Non-adherence to antihypertensive treatment has a negative impact on blood pressure control. There are several strategies to measure adherence to antihypertensive drug treatment, classified as direct and indirect methods. Direct methods are performed through biological analysis (blood or urine). However, they are high-cost alternatives and only available in research environments. In the indirect methods, self-report scales stand out, which are a safe and cost-effective option, as they are simple, low-cost, applicable in various environments and provide immediate feedback, therefore being easy to incorporate into the daily clinical practice. However, to be widely used, an adherence rating scale must be tested and validated, in addition to being available for use at no additional cost. Given the above, the objective of the present study was to validate the General Medication Adherence Scale (GMAS) into Brazilian Portuguese in patients with Systemic Arterial Hypertension. Therefore, this research was carried out in two phases. At first, the cross-cultural validation process of the GMAS instrument from English to Brazilian Portuguese was carried out. This process involved the stages of translation, cross-cultural adaptation and validation and used the methodology described by Beaton et al. In the second phase, a cross-sectional study was carried out in the cardiology sector of hospitals, public and private, in Maceió (AL, Brazil), through the application of the instrument through structured interviews to patients diagnosed with hypertension. In this step, the following analyzes were performed: internal consistency through reliability and test-retest; intraclass correlation coefficients; and Pearson's correlation coefficient to assess content validity. The assessment of convergent validity was performed using the Brief Medication Questionnaire (BMQ) scale. In addition, measurements of blood pressure, measurements of anthropometric parameters and 24-hour ABPM Examination were carried out. Translation and cross-cultural validation generated a Portuguese version of the GMAS scale that was applied to 123 patients. As for the sample, most patients were female (67.5%), and the mean age was 58.47 ± 11.8 years. The scale's internal consistency was 0.75, and its reproducibility could be measured by test-retest, performed using Spearman's correlation (0.761; p<0.001). As for convergent validity, when comparing GMAS and BMQ, they obtained a degree of 77.6% for adherent behavior (p < 0.05). Finally, the discriminant validity was evaluated according to criteria established by the author of the original version of the scale and a relationship between age and adherence was identified, with non-adherent behavior being more frequent among patients considered younger (<45 years) (p <0. 05). The constructs evaluated for adherence were behavior (n=90.73.2%), treatment (n=103, 83.7%) and cost (n=81.65.9%). In view of this, the Brazilian Portuguese version of the GMAS is a valid and reliable tool to measure adherence in patients with hypertension.

The brown and red type propolis from the mangrove region of Alagoas are evidenced in Alagoas, being the red propolis, of defined botanical origin. The study of the chemical composition of brown propolis from the region of União dos Palmares has been the subject of this study. The study of the chemical composition is being carried out through different analytical techniques and analytical methods such as fingerprint studies (fingerprint) and possible botanical origin using HPLC-DAD-UV, LC-Orbitrap-FTMS techniques, chemical assays of total flavonoids and activity antioxidant, as well as microbiological assay of Minimum Inhibitory Concentration. The research consisted of collecting brown propolis from the municipality of União dos Palmares (PMUP) for extraction from September 2019 to August 2021. An amount between 38 and 91g of in natura sample was collected from apiaries close to the municipality of União dos Palmares. The extraction method chosen for PMUP was maceration, in two cycles of 48 hours, using 15 g of PMUP and, for each cycle, 50 ml of hydroethanolic solution at 92.8 ºGL. The extracts were pooled and concentrated to obtain a crude solvent-free extract. Crude extracts 5 (January/2021) and 12 (July/2021) were stored in a freezer until the moment of total flavonoids, antioxidant activity by DPPH, microbiological assays and chromatographic profile assay. A brown propolis key marker isolation study was performed with a brown propolis sample from October 2019 that was subjected to partitioning using liquid-liquid extraction to obtain hexane, hexane-ethyl acetate (9:1), hexane-ethyl acetate (7 :3) and dichloromethane fraction. The dichloromethane phase was subjected to column chromatography on cellulose as a solid support and Methanol:H2O acidified with acetic acid (1%) to obtain fractions between 0% methanol and 100% methanol. The MeOH10%, MeOH20%, MeOH30% and MeOH45% fractions were submitted to semi-preparative HPLC-UV for the isolation of 2 main markers (pk35; pinocembrin) and (pk23; naringenin in mixture with naringenin) of brown propolis (PMUP) that were identified by LC-Orbitrap-FTMS and NMR 1H and 13C. The phenolic compounds identified by the LC-MS technique based on comparison with data from the literature were divided into benzoic acids, cinnamic acids (caffeic acid, ferulic acid), chlorogenic acid, prenylated cinnamic acids (dupranin and artepillin C), stilbene (resveratrol), coumarins and flavonoids divided into flavanonols, flavonones, flavones, flavonols, flavana-3-ol, flavana-4-ol and chalcones. Crude PMUP extracts showed total flavonoid content of 0.5 to 2% based on the quercetin pattern and high antioxidant activity with DPPH free radical scavenging percentage between 80 and 90%. The microbiological assay using Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Candida albicans, Trichophyton mentagrophytes and Microsporum canis strains showed MIC between 32 and 1024 µg/mL for MEOH20% fraction and MIC between 16 and 256 µg/mL for MEOH35% fraction.

Moringa oleifera Lam is a tree vegetable, belonging to the moringaceae family, of Indian origin, cultivated mainly in places with dry tropical climates in various regions of the world. Due to its bioactivity, it has gained enormous attention in the last decade, which has led to increased exploration and understanding of its pharmacological functions and underlying mechanisms. The aim of this study was to characterize phenolic phytochemical compounds and antioxidant activity of hydroalcoholic extracts of Moringa oleifera Lam at different collection times. The collection of samples (powder and tea) was carried out at the Centro de Ciências Agrárias (CECA) from the Federal University of Alagoas (UFAL) in Rio Largo-AL (samples 2019) and in the village Sítio Salão in the municipality of Inhapi-AL. The samples were submitted to hydroalcoholic extraction. The methodology adopted includes Antioxidant activity (DPPH), determination of total flavonoids content (AlCl3), determination of total phenols (Folin-Ciocauteal), analysis of HPLC-DAD and LC-Orbitrap_ESI-FTMS. The DPPH radical scavenging capacity assay of the 2019 Powder samples showed good results with high antioxidant capacity for MO50% extract (>85%), followed by MO40% extract (>62%), MO30% extract (30.42%) and extract MO20% (21.33%), also being noticeable that the antioxidant capacity was concentration dependent. Samples of MO powder extracts collected in 2021 showed that extracts collected in June, July and August using a high percentage of alcohol (50% and 75%) during the extractive process showed an IC50 result of less than 50 µg/mL. The MO tea samples collected in 2021 consolidated the study of antioxidant activity, showing that hydroalcoholic extracts with a lower percentage of alcohol (MO25% tea extract) had lower antioxidant activity than the extracts with a higher percentage of alcohol used in the extraction (MO50% tea and MO75% tea). The MO powder samples showed higher antioxidant capacity than the MO tea samples. The MO powder samples exhibited significant total flavonoid contents between 1.14% and 2.35%, highlighting the months of June powder 50% with 2.35% and August powder 75% with 2.00%, 1, 14% August powder 50%, while the months of January and February showed values between 0.67% and 0.98% of total flavonoids, respectively.The analysis of the total phenol content showed a high content in the months of intense sunlight with values of 13.39% and 8.38% for the months of January and February, respectively; while the rainy months (June, July and August) showed minimal variation with values between 5.39% (July) and 5.78% (June). The LCMS assay using the analytical standards method identified the presence of acid flavonoids caffeic acid, 2-coumaric acid, umbelliferone, p-coumaric acid, vitexin, rutin, quercetin, kaempferol, luteolin, apigenin, pinocembrin at high intensities in samples of moringa extract February and July 75% powder. The LC-MS assay also detected the presence of isoquercitrin, quercetin 3-O-malonylglucoside (m/z 550.0927), kaempferol 3-O-(6´´-malonylglucoside) (m/z 489.1493) and kaempferol 3-O-glucoside (m/z 447.2616) known as astragalin based on scientific literature data. In general, the antioxidant activity and flavonoid content of MO powder extracts increased in the months of heavy rainfall (June, July and August), decreasing significantly in the months with low rainfall. While the total phenol content was higher in the months of intense sunshine and lower in the rainy months. The LC-MS data corroborate this information with lower values for ferulic acid and caffeic acid (February sample) and higher values for flavonoids (vitexin, rutin, quercetin, kaempferol, luteolin) in the July sample.

Introduction: The α- terpineol (TPN) is a monoterpene obtained from Protium hepthaphylum. That has several pharmacological activities such as: anti-inflammatory, anti-obesity and cardioprotection on Spontaneously Hypertensive Rats (SHR) by isoproterenol model. ISO evoked metabolic disturbance on hepatocytes, stimulate fatty acids storage on vesicles inducing non-alcoholic steatosis. The aims of this study were verify the hepatoprotective effects of TPN in SHR against liver damage induced by ISO. Methods: Experimental protocols were approved by the CEUA/UFAL nº09/2015. Male rats were allocated into 5 groups and treated for 15 days (n=5): (G1= saline 0.9% P.O/d); (G2= Infarcted saline 0.9% P.O./d + ISO 85mg/kg 2x s.c); (G3= TPN 25 mg/kg P.O./d); (G4=TPN 50 mg/kg P.O./d) and (G5=TPN 75 mg/kg P.O./d). On 16º day, rats were anesthetized (Ketamine 80 mg/kg + Xylazine 4 mg/kg i.p.) and morphometric tests were performed in accordance with Scherle´s methods. Morphology tests were examined under light by stereoscopy, while lipid levels were estimated by total cholesterol and triglyceride dosages of blood serum. The results were expressed as mean ± SEM, and analyzed statistically by ANOVA one-way followed by Newman- Keuls test considered significant when * p <0.05, ** p<0.001 and *** p< 0.0001. Results: Weight of the liver (G1= 6.92 ± 0.22g/g* vs. G2= 8.67 ± 0.3g/g), (G4= 6.40 ± 0.36g/g* vs. G2= 8.67 ± 0.31g/g), (G5= 5.22 ± 0.7g/g*** vs. G2= 8.67 ± 0.31g/g) and (G3= 7.44 ± 0.6g/g vs. G5= 5.22 ± 0.7g/g), reason liver weight by body weight (G3=1.86 ± 0.05g/g* vs. G4= 2.44 ± 0.16g/g), (G3=1.86 ± 0.05g/g** vs G5= 2.64 ± 0.23g/g), (G4= 2.44 ± 0.16g/g *vs. G2= 1.68 ± 0.05g/g) and (G5= 2.64 ± 0.23g/g** vs. G2= 1.68 ± 0.05g/g) and reason liver weight by femur weight (G1= 65.7± 9.24g/g**** vs. G2= 547.4 ± 7.15g/g), (G3= 834.4 ± 9.51g/g**** vs. G2= 547.4 ± 7.15g/g Through morphological and histopathological aspects, it was observed that TPN inhibited non-alcoholic hepatic steatosis due to damage caused by induction with isoproterenol, in addition, previous treatment with TPN significantly inhibited the increase in total cholesterol levels (G1= 21,5 ± 1,0 vs. G2= 68,1 ± 1,2****), (G2= 68,1 ± 1,2****vs. G3 = 20,7 ± 1,3****), (G2= 68,1 ± 1,2**** vs. G4 = 22,6± 1,5****) and (G2= 68,1 ± 1,2****vs G5= 22,3 ± 4,6 ****) and triglyceride G1= 23,4 ± 1,6 vs. G2= 353,4 ± 23,3 ****), (G2= 353,4 ± 23,3 vs. G3 = 28,9 ± 2,8****), (G2= 353,4 ± 23,3 vs. G4 = 27,5± 1,7****) and (G2= 353,4 ± 23,3 vs G5= 16,2 ± 1,5 ****), levels at all doses tested. In addition, after the glucose tolerance curve, it was noted that there was a reversal in this curve, which may also influence glucose metabolism, however further studies are needed. Conclusion: Taken together, the results indicate that TPN has a significant hepatoprotective effect, in hypertensive and infarcted rats.

Essential oils are complex substances that have in their composition several constituents that give these oils biological activities. The clove (Syzygium aromaticum) is an arboreal plant of the Myrtaceae family that has been used in medicine since ancient times, possessing an antioxidant, anesthetic, insecticidal and antimicrobial activity. The encapsulation technique by ionic gelation consists of producing spheres by electrostatic interactions between ionic polymers and ions with different charges, in order to form a three-dimensional network, for the entrapment of the active compound. In this context, the objective of this work was to develop alginate globules loaded with clove essential oil through the ionic gelation technique, identify and quantify the main marker of clove essential oil, quantify the total phenols and evaluate the antioxidant potential and thermally characterize the alginate globules carried with clove essential oil. The globules were obtained by the ionic gelation technique. Essential oil and globules were evaluated for antioxidant activity by DPPH methods. Quantification of total phenols was performed using the Folin-Ciocalteau method. Identification and quantification of the main oil marker were performed by GC-MS. The thermogravimetric stabilities of the globules were evaluated by TGA and DSC. Contents of 1190.66, 714.84 and 433.43 mg EAG g-1 of total phenolic compounds were found in the essential oil and globules of 1% and 2% alginate, respectively. The DPPH antioxidant method showed high activities where in the EO the percentage was from 28.16% to 80.27% and in the 1% alginate globules 12.90% to 59.36%, 2% alginate globules 11, 19% to 31.79%. Eugenol was the major compound in the essential oil with a content of 83.73. The encapsulation efficiency was 7.12% in the 1% alginate formulation and 10.22% in the 2% alginate formulation. The globules presented a translucent appearance, while those with the oil presented an opaque color, closer to white. Thermal analysis showed good stability for the globules. The ionic gelation process was successful, providing greater thermal stability to the clove essential oil, maintaining its biological properties.

Red propolis from Alagoas is a sticky resin made from a complex mixture of biologically active substances with great biotechnological potential. Various studies have shown that red propolis extracts have a wide variety of biological activities as an antioxidant. Drug-excipient compatibility testing is one of the most fundamental phases in the pre-formulation research process. Given the above, this research aims to evaluate compatibility and thermal stability of red propolis associated with different excipients in obtaining polymeric membranes. The ethanolic extract of red propolis by maceration. Assays were carried out to quantify the content of phenolic compounds, using the Folin-Ciocalteu reagent method, and flavonoids, using the aluminum chloride method of the EEPV. The investigation of the antioxidant activity of EEPV was carried out using the DPPH method. Synthetic membranes were prepared using the solvent evaporation method. And the physical-chemical properties of thermal stability of membranes, components, and binary mixtures were analyzed by Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetric Analysis (DSC). It was estimated that the content of total phenolic compounds was 208.0 mg EAG.g-1, and the total flavonoid content was 45.3 mg EAG.g-1. The analysis of the antioxidant activities of EEPV by the DPPH method varied between 59.36% and 88.31%. The thermal profile obtained by the EEPV TGA showed 4 thermal degradation events, none of which were superimposed. The second event (onset: 82.01 °C, endset: 135.29 °C and mass loss of 12.83%). Thermogravimetric thermal analyzes (TGA) showed sodium benzoate as the most stable excipient. Second curve (onset: 514.77 °C, endset: 562.11 °C and mass loss of 44.79%). Propylene glycol was the least stable excipient. Its second thermal event (onset: 117.43 °C, endset: 147.35 °C and 82.57% mass loss). Membranes and binary mixtures were successfully obtained and presented a uniform appearance. The MX1 membrane presented 7 thermal degradation events, with the 1st overlapping with the 2nd, the 3rd with the 4th, and the 6th with the 7th. The second thermal event (onset: 54.75 °C, endset: 104.48 °C and mass loss of 15.88%). The EEPV decomposition curve by DSC showed two thermal events. The first transition process was endothermic (onset: 153.32 °C; endset: 364.35 °C; peak: 346.48 °C; enthalpy: -152.62 J/g). The EEPV + sodium benzoate binary mixture curve showed 6 thermal events. The first event was endothermic (onset: 35.12 °C; endset: 79.85 °C; peak: 61.38 °C; enthalpy: -36.04 J/g). The MX1 decomposition curve by DSC showed 4 transition processes. The first and third being endothermic, and the second and fourth exothermic. The first (onset: 126.49 °C, endset at 136.09, and enthalpy: -21.53 J/g). Thus, the red propolis ethanolic extract showed good thermal stability. And, among the excipients, sodium benzoate was the most thermally stable. In contrast, propylene glycol was the excipient with the lowest thermal stability. And all excipients were compatible with red propolis ethanolic extract. All membranes were successfully obtained, however thermogravimetric analysis (TGA) determined that MX1 has better thermal stability.

Chronic kidney disease (CKD) is considered a global public health problem, especially in low- and middle-income countries, as they are less prepared to deal with the prevention, treatment and progression of CKD. Early detection of CKD and therapeutic follow-up of patients with hypertension and diabetes are necessary to reduce morbidity and mortality. Stage 3 and advanced stages 4 and 5 of CKD were associated with 2.2 million deaths in the global population, more than half of which were from cardiovascular disease, while 0.96 million deaths were related to end-stage renal disease. Furthermore, risks increase when prescribed medications are not adhered to. Patients undergo hemodialysis three times a week, starting early in the morning, and there may be chronic changes in sleep schedules due to waking up early or sleeping late. In the literature, the prevalence of sleep disorders and poor medication adherence in patients with CKD are well evidenced, but there are few studies on whether sleep-related problems are associated with poor medication adherence. In addition, until the time of the study, there were no reports in the literature on the identification of circadian chronotype and occurrence of social jetlag in hemodialysis patients. In view of this, the study aims to analyze the behavior of circadian preference and sleep-related problems if they are associated with therapeutic adherence in patients on hemodialysis. A cross-sectional study was carried out with 108 patients with CKD undergoing hemodialysis treatment in three hospitals in Maceió from June to November 2022. Data collection was performed through interviews with the patient using the following validated questionnaires: Pittsburgh Sleep Quality – PSQI, EPWORTH Daytime Sleepiness Scale, Chalder Fatigue Scale, Morisky Therapeutic Adherence Scale (MMAS-8), Obstructive Sleep Apnea Risk Factor Questionnaire – STOP-Bang, Morningness Eveningness Questionnaire – MEQ and Munich Chronotype Questionnaire - MCQT. Questions about health conditions, life habits, sociodemographic data and continuous use medication were also addressed. The main results obtained, patients had a morning circadian preference (56.5%), among the concomitant diseases, hypertension was the most frequent (60.2%), patients used cell phones before going to sleep (61.1%) and 13% exceeded cell phone use for more than 2 hours. Short sleep duration was observed in patients, 62.9% had a sleep duration < 6 hours, poor sleep quality (81.5%), high-risk prevalence of obstructive sleep apnea syndrome (64.8% ), low adherence to medication (72.2%) and occurrence of social jetlag in patients for more than 1 hour (56.5%). The associations were significant between daytime sleepiness, fatigue and chronotype with therapeutic adherence. Therefore, the results indicate worrisome problems that can lead to complications in comorbidities and worsen the prognosis. Clinical trials reinforce the importance for future studies to determine the best method or combination of different methods to manage medication adherence and integrate pharmaceutical care into patients' daily routine.

Use of medicines and psychoactive substances by UFAL students during the COVID-19 pandemic The Pandemic caused by SARS-CoV-2 is considered the biggest public health problem faced by humanity in this century. It has been responsible for causing important changes in lifestyle, in interpersonal relationships, resulting in an increase in domestic violence, traffic accidents, unemployment, psychological problems, changes in the undue and indiscriminate consumption of licit and illicit drugs, and medication, reduction quality of life and well-being, as well as reduced productivity and schooling. Students make up a segment of the population with considerable vulnerability to the use of psychoactive substances. This topic is the subject of research, as the consumption of psychoactive substances can impact the student's academic and personal life. The objective of the study is to determine the profile of students at the Federal University of Alagoas, within the scope of Psychosocial Toxicology, regarding the use and local pattern of use of psychoactive substances (licit, illicit and medicines), considering the pandemic caused by the new coronavirus. This is a descriptive quantitative study. For the elaboration of the research, the screening instruments, AUDIT and ASSIST, were used, aimed at undergraduates, which allowed the remote application of a questionnaire. Statistical analysis was performed using the EpiInfo 7 program. Univariate analysis was performed to describe quantitative variables related to the social and educational profile. Bivariate analysis to identify the association between psychoactive substances and social and educational variables, with the chi-square test and 5% significance. 256 responses were obtained. As for the AUDIT, 68.01% of the students reported consuming alcohol, with 6.64% presenting behavior suggestive of abuse. Of those surveyed, 14.69% reported not being able to stop drinking once they started. Changes in behavior, feelings of guilt, and inability to remember facts when drinking were observed, in addition to a trend towards increased alcohol use in both sexes during the pandemic. The ASSIST pointed to an increasing trend in the use of tobacco, alcohol and marijuana derivatives, in addition to the report of significant consumption of antidepressants and anxiolytics. The use of cocaine/crack, amphetamines, inhalants, sedatives and hallucinogens was also reported. A relationship was identified between exact sciences courses and increased use of tobacco derivatives [(18.87%) p=0.0391], marijuana [(20.75%) p=0.0066], anxiolytics [ (13.21%) p=0.9946], from the human area and increased consumption of hypnotics/sedatives [(11.58%) p=0.0202] and anti-adhesive drugs [(18.95%) p=0 .0489]. Thus, the research pointed to a diversification in the use of psychoactive substances among university students and the contribution to outline a consumption profile in order to support the elaboration of internal policies aimed at undergraduates regarding the confrontation of the use of these substances in the academic environment.

Introduction: Hypertension is one of the most prevalent chronic diseases in Brazil and in the world and has been one of the underlying comorbidities most related to death from cardiovascular causes. In the context of the Covid-19 pandemic, it has been observed that these patients are at greater risk of developing severe infections and post-covid sequelae, as well as a worse prognosis for their underlying disease. In this way, it is necessary to understand how covid-19 has impacted the health of patients with hypertension. Objective: To assess the prevalence of blood pressure control and associated factors among patients with systemic arterial hypertension (SAH) in the context of the covid-19 pandemic. Methods: Cross-sectional study nested within a retrospective cohort study carried out in outpatient cardiology services in hospitals in Maceió. A total of 110 patients with SAH undergoing drug treatment were included. In order to obtain the data, questionnaires were applied through face-to-face interviews and analysis of the medical prescription, as well as measurement of physiological measures such as blood pressure, weight and height. To verify therapeutic adherence to antihypertensive medication, the Brief Medication Questionnaire (BMQ) scale was applied. Results: The mean age was 58.2 years (SD= 11.3) with a predominance of females 68.2%. As for treatment for SAH, 43.64% were on dual therapy and the average number of medications per patient was 2.14. Only 32 (29.1%) participants had blood pressure control, contradictorily 67.3% had good adherence to the SAH treatment. Mean systolic blood pressure was 138.05 mmHg (SD=19.9) and mean diastolic blood pressure was 81.20 mmHg (SD=11.6). The prevalence of covid-19 among hypertensive patients was 37.3% (n=41) of these 39 underwent treatment for covid, however, only 25 reported remembering the medications, 69 reported drugs, with an average of 2.76 medications per respondent . On the other hand, 35.5% (n=39) of patients self-medicated as a means of preventing covid-19, a total of 50 medications were mentioned, with an average of 1.28 medications per patient. Of which ivermectin was the most prevalent 42%. Post-covid sequelae had a frequency of 58.5% (n=24) in the group that reported having covid-19 (n=41), the most related health problem after infection was fatigue with 37.5% (n=9) in this subset. Conclusion: The low prevalence of covid-19 among respondents was possibly limited due to survivor bias. For this group, having had covid-19 was not related to a worse clinical situation of the underlying disease (SAH), factors associated with non-control of SAH were BMI measurements of male abdominal circumference.

Leishmaniasis is a neglected, infectious, and non-contagious disease caused by parasites of the genus Leishmania. Leishmania has two evolutionary forms, promastigote and amastigote, and two main clinical manifestations: cutaneous and visceral, with the latter being of greater concern as it can lead to the patient's death if untreated. Despite the complexity of the disease, the therapeutic arsenal remains limited, with pentavalent antimonials being the first choice and drugs like amphotericin B and pentamidine as the second choice. However, this therapy presents undesirable adverse effects, along with significant cytotoxicity and parasitic resistance. In light of this issue, the present study evaluated extracts from fungus producing secondary metabolites from Antarctica, and also conducted a patent review regarding the leishmanicidal activity of fungal metabolites. In the experimental study, the biomass of these fungi was produced, followed by solvent extraction using ethyl acetate and acetone, pigment concentration, drying, dilution, cell viability tests (MTT), and evaluation of leishmanicidal activity against the promastigote form of L. amazonensis and L. chagasi. Yeast extracts (19L15, 4L2, 2L19, NL1, and GL19) and filamentous fungus extracts (4FFLQ2, 5YP4, 2FFLQ6 acetate, 2FFLQ6 acetone, 1EMP1, 3EMP4, and 2EMP4) were produced and tested at concentrations of 100, 30, 10, 3, 1, and 0.3 µg/mL. In the cell viability assay, the maximum cytotoxic effect found for yeast extracts was 40.54 ± 3.37%; 24.37 ± 3.66%; 29.09 ± 3.57%; 6.28 ± 1.00%; 22.98 ± 1.63%, respectively. The cytotoxic effect of filamentous fungi was: 60.53 ± 2.50%; 67.33 ± 1.51%; 19.68 ± 6.62%; 19.68 ± 6.62%; 23.38 ± 7.16%; 17.30 ± 10.59%; 29.08 ± 18.80%, and NA. In the assay to evaluate leishmanicidal activity, the tested yeast extracts (for both species) and filamentous fungus extracts (for L. chagasi) were not lethal to the parasites even at the maximum tested concentration of 100 µg/mL. The extracts 2FFLQ6 acetate and 2FFLQ6 acetone exhibited a maximum effect of 74.36 ± 4.10% and 84.62 ± 5.32% against the L. amazonensis species, suggesting the need for further studies in this area. In the patent review, four patents were selected, which demonstrated activity against L. major, L. amazonensis, and L. donovani species, along with low toxicity. Despite the results, the subject is still underexplored by the academic community, and the continuation and encouragement of bioprospecting research using fungal isolates and extracts is warranted.

The characterization of solids for the development of pharmaceuticals and medicines is essential to ensure the processing, transport, and storage of final products. Acrylamides are organic substances, some of which are active against Dengue (DENV) and Zika (ZIKV) viruses, showing significant biological action and low toxicity in human cells. In recent decades, it has been noted a growing number of cases of pests infection by chikungunya (CHIKV), this disease, is quite neglected, with the absence of vaccination and treatments. The study and characterization of active molecules are of great importance for therapeutic alternatives still unknown or little explored. Thus, characterization by thermal analysis and complementary analytical techniques for solids are essential tools for the development of new drugs, as they provide data on the thermal behavior and chemical structure of materials. The work aimed to determine the thermal stability and degradation of the microstructures of acrylamides LQM330, 333, 336, and 338 active against the virus CHIKV. The characterization of the molecules was carried out by thermogravimetry (TG), Differential Scanning Calorimetry (DSC), Spectrophotometry in the Ultraviolet and Visible Region (UV-vis) It in the infrared region with Fourier transform (IRTF), Gas chromatography coupled to mass spectrometry (GC/IN), High-Performance Liquid Chromatography (HPLC) It is Scanning electron microscopy (SEM). The obtained results showed that LQM330 molecules, 333, 336, and 338 showed GC/MS and HPLC purities in the range of 92.50 to 99.55 and from 99.81 to 98.88%. The TG curves demonstrated that the molecules are stable at indifferent heating rates (10,20,30,40, and 50 ºC/min). Thermal decomposition profiles are very similar among acrylamides, with the presence of an endothermic event, except for sample LQM330 that presented exothermic events by DSC, this technique also provided data on the purity of the molecules in the range of 96.31% to 98.82%. The UV-vis spectra evidenced that the speak maximums of absorption for around 220 to 335 nm. Already the IR spectra TF demonstrated the presence of C=O stretching and NH stretching. The samples showed morphology heterogeneous, brittle with clusters in general, except for samples at T600 C that expose Forms of whole and homogeneous cubes, results verified by SEM. Soon, the good thermal stability of the molecules confirmed that they are promising candidates for the development of future drugs against the virus CHIKV and, that characterization by thermal analysis and complementary analytical techniques provided specific and crucial data for the advancement of the pharmaceutical sector.

Leishmaniasis is still one of the most neglected diseases in the world, affecting millions of people mainly in poor and underdeveloped countries. In Brazil, leishmaniasis is a public health problem due to its ease of propagation and ability to cause epidemics. Given this scenario, pyroligneous extracts have drawn the attention of many researchers, given that their processing can contribute to the development of chemical entities with pharmacological potential. In the Technological Prospecting carried out, it was possible to observe the formulation of innovations using pyroligneous extracts for therapeutic purposes and the application of these extracts in the treatment of pathologies such as cancer. The exercise of technological prospection is fundamental to guide the development of new technologies. In the experimental study, seven extracts from plants typical of the Brazilian flora were tested. All extracts showed leishmanicidal effects for the evolutionary form of promastigote amazonensis (100% ± 0.00) with IC 50 ranging from 0.01% (Mimosa tenuiflora) to 0.26% (Eucalyptus), however, they showed cytotoxic effects in the order of 95.13% (Pennisetum purpureum) for macrophages of the J774.A1 strain in the MTT assay. The results obtained in the pharmacological tests associated with those presented in the Technological Prospecting indicate that studies need to be implemented in order to standardize an extraction method, thus favoring the obtainment of compounds with pharmacological properties.

Pesticides and herbicides are intended to improve crop productivity, protecting them and preventing the proliferation of pests. Equally, the use of veterinary products is based on the search for higher yields in livestock. In this context, substances derived from the element arsenic (As), such as sodium methylarsinate (MSMA), are present in several products for veterinary and agricultural use. Considering that such products are widely used in Brazil, and other countries, the topics that clarify the risks and toxicity of these compounds have not yet been fully explored. Metabolomics is a branch of the omics sciences that seeks to understand, through the analysis of the metabolites produced in a given organism, which factors influence specific metabolic changes, whether these occur due to lifestyle habits or exposure to any xenobiotic. The metabolomics strategy includes the analysis of biological samples using equipment such as Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR). Thus, this project aimed to investigate, through an ecotoxicological study associated with metabolomics based on 1H NMR, the proportion of impact that arsenic compounds in water can provoke on aquatic species such as zebrafish (Danio rerio). The choice of this species as a model organism was due to its considerable versatility in bioassays. The toxicity study was based on the acute exposure of embryos to MSMA, with serial concentrations in order to obtain the LD50. Sampling for the metabolomic study followed the protocols available in the literature, associated with 1H NMR spectroscopy and statistical study to get the metabolic profile. Thus, the metabolomic analysis revealed 42 metabolites involved in different metabolic pathways. The biochemical profile study suggested that MSMA caused severe impacts, especially on pathways of energy metabolism, endocrine metabolism, hepatic metabolism, and oxidative stress.
