Abstract
Thirteen fucosterol derivatives were prepared by structural modification at the hydroxyl group in C-3 and catalytic hydrogenation at the carbon-carbon double bond in C-5(6) and C-24(28). The structures of all compounds were established based on their spectral data (IR, MS, and NMR). Fucosterol (1) and its derivatives (2-12, and a mixture of 13a and 13b) were evaluated for their in vitro antibacterial activity against Klebsiella pneumoniae (ATCC 10031), Escherichia coli (ATCC 10536), Pseudomonas aeruginosa (ATCC 15442), Streptococcus mutans (ATCC 0046) and Staphylococcus aureus using the microdilution method. Among them, 1, 8, 9, 10, and a mixture of 13a and 13b exhibited the best antibacterial activity. The derivative 7 was inactive against all bacterial strains evaluated (MIC ≥ 2.327 mM). In addition, the investigation of binding interactions of more active compounds (1, 8, 9, 10, and mixture of 13a and 13b) to appropriate proteins was performed using molecular docking. This paper registers for the first time the in silico studies on the antibacterial activity of compounds 1, 8, 9, 10, and mixture of 13a/13b, and the spectral data of compounds 4, 6, and 7.

Abstract
Species from the Annona (Anonaceae) genus are used in traditional medicine for the treatment of various
diseases. Ethnobotanical studies provide information regarding the plant part and the preparation method
being used, while scientific studies such as in vitro, in vivo, and clinical tests can provide evidence supporting
ethnopharmacological reports, directing studies towards the isolation of compounds which may be active for
specific pathologies. Annona muricata and Annona squamosa were the most commonly reported species from
those studied, with Annona cherimola and Annona classiflora also standing out. Acetogenins were the most
commonly isolated metabolite class due to their cytotoxic properties, with flavonoids, alkaloids, steroids, and
peptides also being reported. Many species from the Annona genus have proven biological activities, such as
antitumor, antioxidant, antimicrobial and antifungal. The present review had as its objective to facilitate access to
ethnobotanical, chemical and biological information in order to direct future researches.

Abstract
In this study the physicochemical characterization of the pulp and almond fixed oil was carried out; their antibacterial activity and aminoglycoside antibiotic modifying action against standard and multiresistant Gram-positive and -negative bacteria were investigated using the broth microdilution assay. Physical properties such as moisture, pH, acidity, peroxide index, relative density and refractive index indicate stability and chemical quality of the oils. In the GC/MS chemical composition analysis, a high unsaturated fatty acid content and the presence of oleic and palmitic acids were observed in the oils. In the antibacterial assay, more significant results were obtained for Escherichia coli, while other standard and multi-resistant strains presented MIC values ≥ 1024 μg/mL. Furthermore, the fixed oils in association with antibiotics were able to significantly improve antibacterial activity against S. aureus with a reduction in MICs.

Abstract
In order to develop bioactive lithocholic acid derivatives, we prepared fifteen semi-synthetic compounds through modification at C-3 and/or C-24. The reactions showed yields ranging from 37% to 100%. The structures of all compounds obtained were identified on the basis of their spectral data (IR, MS, 1D- and 2D-NMR). The activity of lithocholic acid and derivatives was evaluated against the growth of Escherichia coli, Staphylococcus aureus, Bacillus cereus and Pseudomonas aeruginosa. The derivative 3α-formyloxy-5β-cholan-24-oic acid (LA-06) showed the best activity, with MIC values of 0.0790 mM against E. coli (Ec 27) and B. cereus in both cases, and 0.0395 mM against S. aureus (ATCC 12692). Lithocholic acid and the derivatives with MIC⩽1.2 mM were evaluated on the susceptibility of some bacterial pathogens to the aminoglycoside antibiotics neomycin, amikacin and gentamicin was evaluated. There are no previously reported studies about these compounds as modifiers of the action of antibiotics or any other drugs.

Abstract
Background The challenge of antibiotic resistance and the emergence of new infections have generated considerable interest in the exploration of natural products from plant origins as combination therapy. In this context, crude ethanolic extract (CEE), ethyl acetate fraction (EAF), and methanolic fraction (MF) from Anacardium microcarpum were tested alone or in combination with antibiotics (amikacin, gentamicin, ciprofloxacin, and imipenem) against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Methods Antibiotic resistance-modifying activity was performed using the microdilution method by determining the minimal inhibitory concentration (MIC). In addition, phytochemical prospecting analyses of tested samples were carried out. Results Our results indicated that all the extracts showed low antibacterial activity against multidrug-resistant strains (MIC =512 μg/mL). However, addition of CEE, EAF, and MF to the growth medium at the subinhibitory concentration (MIC/8=64 μg/mL) significantly modulated amikacin- and gentamicin-resistant E. coli 06. CEE and EAF also demonstrated a significant (P<0.001) synergism with imipenem against S. aureus. In contrast, MF antagonized the antibacterial effect of ciprofloxacin and gentamicin against P. aeruginosa 03 and S. aureus 10, respectively. Qualitative phytochemical analysis of the extracts revealed the presence of secondary metabolites including phenols, flavonoids, xanthones, chalcones, and tannin pyrogallates. Conclusion Taken together, our results suggest that A. microcarpum is a natural resource with resistance-modifying antibacterial activity that needs to be further investigated to overcome the present resistant-infection problem.

Abstract
Evaluations of the therapeutic potential of medicinal plants and their components have been the subject of many studies. Furthermore, the biological activities of various plant species have been reported in various pieces of literature. Hyptis martiusii Benth (Lamiaceae), popularly known as "mad balm" is commonly found in the North, Southeast, and Northeast of Brazil. Its leaves are used ethnobiologically as antiulcerogenic, antimicrobial, antitumor and as insecticide. This study aimed to analyze the chemical composition of the essential oil of H. martiusii Benth (OEHM) by GC/MS as well as its possible topical activity as an antiedematogenic. This is verified by the models of ear edema induced by single (acute edema) and multiple (chronic edema) applications of croton oil topically, and systemically verified through the model of paw edema induced by carrageenan 1%. Doses of 50, 75 and 100 mg/kg OEHM were used in all tests. Chemical analysis of the oil revealed the 1,8-cineole (34.58%) and δ-carene (21:58%) as major components present in the essential oil. On the model of ear edema, acute and chronic OEHM in all the tested doses showed no significant antiedematogenic activity (p < 0.05). The systemic model of paw edema induced by carrageenin showed that a dose of 100 mg/kg effectively reduced swelling by 55.37% in the second hour evaluation when compared to the saline group. The anti-inflammatory systemic effect can give greater bioavailability of the components present in the essential oil and your interference in cytokines and leukotriene, thromboxane and prostaglandin biosynthesis. It is therefore concluded that OEHM presents systemic antiedematogenic activity but not topical activity at these doses.

Abstract
BACKGROUND The use and investigation of natural products with antimicrobial activity from vegeral source have been reported by several researchers. Cajanus cajan (Fabaceae) is a multiple use specie mainly as human food. In popular medicine, diverse parts of the plant are used as sedative and to treat cough, hepatitis, and diabetes. MATERIALS AND METHODS This study shows the characterization of secondary metabolites present in ehtanolic extracts from leaves and roots of Cajanus cajan by phytochemical prospection. The evaluation of the antifungal activity was performed by the microdilution method, and from the subinhibitory concentrations (MIC 1/8) the modulatory activity of antifungical (fluconazole and ketoconazole) was analyzed by the direct contact assay against C. albicans ATCC40006, Candida krusei ATCC 6538 and Candida tropicalis ATCC 40042. RESULTS The results showed the presence of tannins, flavonoids, and alkaloids in both extracts as the clinically relevant antifungal activity. The modulatory potential is presented by the antifungal tested against yeasts. CONCLUSION The extracts studied here have demonstrated to be a new therapeutic source to treat these microorganism-associated diseases.
