“…As reference drugs, the itraconazole inhibitor (1YN) was used, which is complexed with the enzyme (PDB 5V5Z) (Keniya et al, 2018) and fluconazole, one of the main antifungals used for Candida spp. (Sueth-Santiago et al, 2015) For anticholinesterase activity, (-) -Galanthamine was used. The ligands must be in their best potential energy state for the simulations; therefore, they were optimized by the semiempirical parametric method 7 (PM7) (Stewart 2013;Almeida-Neto et al, 2020) using the MOPAC® software.…”

“…Pointed out as one of the main causes of mortality in immunocompromised patients, fungal infections caused by Candida species have been gaining prominence (Sueth-Santiago et al, 2015). One of the main classes of antifungals, triazoles, Colombo et al, 2013).…”

“…A target of azoles, the enzyme lanosterol 14α-demethylase (CYP51) plays a fundamental role in the process of biosynthesis of fungi ergosterol (Keniya et al, 2018;Sueth-Santiago et al, 2015;Hess & Smentek 2013). The inhibition of CYP51 prevents the formation of ergosterol, weakening the fungal cell membrane Colombo et al, 2013),…”

The aim of the present study was to investigate the biological activity of A. sativum essential oil against clinical isolates of C. albicans and, in addition, a computational study of the action of two main compounds of the essential oil on the protein of the fungus CYP51 was carried out. The Minimum Inhibitory Concentration and the Minimum Fungicidal Concentration were determined by the broth microdilution method. The biofilm formation was evaluated by biomass quantification using the violet crystal staining method. For the study of molecular docking computer simulations of interaction between CYP51 and ligands were performed using the AutoDock Vina code. The main constituents were diallyl disulfide, followed by diallyl disulfide. The essential oil demonstrated activity against clinical isolates of C. albicans. The essential oil showed a reduction progressive increase in the biomass produced from the biofilms of all yeasts tested in this study. The ligands Diallyl disulfide, Diallyl trisulfide and fluconazole formed complexes with the protein target. Based on the results, the essential oil of A. sativum can be considered promising product for the development of new drugs in the prevention of infections associated with C. albicans. This study characterizes the effects of A. sativum essential oil against clinical isolates of C. albicans responsible for the development of pathologies in humans.

“…Trypanosoma cruzi, an intracellular protozoan parasite, is the causative agent of Chagas disease, which affects nearly 8 million people worldwide [1]. Multiple factors contribute to the clinical course of this infection, but the host immune response appears to be essential in coordinating the parasite replication and cardiac pathogenesis [2][3][4]. In this context, the production of cytokines and chemokines has been shown to essentially regulate leukocyte recruitment during T. cruzi infection, which could eliminate the parasite but also worsen the clinical condition [5][6][7].…”

The protozoan Trypanosoma cruzi is responsible for triggering a damage immune response in the host cardiovascular system. This parasite has a high affinity for host lipoproteins and uses the low-density lipoprotein (LDL) receptor for its invasion. Assuming that the presence of LDL cholesterol in tissues could facilitate T. cruzi proliferation, dietary composition may affect the parasite-host relationship. Therefore, the aim of this study was to evaluate myocarditis in T. cruzi-infected C57BL/6 mice—acute phase—fed a high-fat diet and treated with simvastatin, a lipid-lowering medication. Animals (n=10) were infected with 5×103 cells of the VL-10 strain of T. cruzi and treated or untreated daily with 20 mg/kg simvastatin, starting 24 h after infection and fed with a normolipidic or high-fat diet. Also, uninfected mice, treated or not with simvastatin and fed with normolipidic or high-fat diet, were evaluated as control groups. Analyses to measure the production of chemokine (C-C motif) ligand 2 (CCL2), interferon- (IFN-) γ, interleukin- (IL-) 10, and tumor necrosis factor (TNF); total hepatic lipid dosage; cholesterol; and fractions, as well as histopathological analysis, were performed on day 30 using cardiac and fat tissues. Our results showed that the high-fat diet increased (i) parasite replication, (ii) fat accumulation in the liver, (iii) total cholesterol and LDL levels, and (iv) the host inflammatory state through the production of the cytokine TNF. However, simvastatin only reduced the production of CCL2 but not that of other inflammatory mediators or biochemical parameters. Together, our data suggest that the high-fat diet may have worsened the biochemical parameters of the uninfected and T. cruzi-infected animals, as well as favored the survival of circulating parasites.

“…Imidazolium salts (IS) are ionic compounds consisting of an organic cation, carrying an imidazolium ring and an organic or inorganic anion (Schrekker et al, 2008(Schrekker et al, , 2013. These compounds have antifungal action related to the inhibition of the enzyme sterol-14α-demethylase (CYP51) (belonging to the cytochrome P450 family), which in turn act on the integrity of the fungal membrane (Sueth-Santiago et al, 2015). For this reason, they are of interest for pharmaceutical drug development with proven action on fungi of medical importance, such as Candida albicans (CP Robin) Berkhout and Rhodotorula mucilaginosa (A Jörg.)…”

Sericulture in Brazil is an activity developed mainly by families on small rural properties, contributing to improving workers' income and reducing rural exodus (Meng et al., 2017). This configures a low technological level for the breeding environment of silkworm, Bombyx mori L. (Lepidoptera: Bombycidae), and among the problems associated with sericulture that directly affect the quality of the threads, the diseases caused by entomopathogenic viruses, bacteria, and fungi stand out (
