1,3-Oxazole derivatives of cytisine as potential inhibitors of glutathione reductase of Candida spp.: QSAR modeling, docking analysis and experimental study of new anti-Candida agents
“…Among the various derivatives of cytisine, compounds are constantly found with other types of biological activity that are not characteristic of itself (antispasmodic, antiarrhythmic, hepatoprotective, analgesic, cholinergic, insecticidal, antioxidant, etc. ), which attracts attention and encourages the synthesis and study of its new derivatives [9,10]. Small doses of cytisine strongly arouse breathing and increase blood pressure.…”
QSAR analysis of a 5143 compounds set of previously synthesized compounds tested against multi-drug resistant (MDR) clinical isolate Escherichia coli strains was done by using Online Chemical Modeling Environment (OCHEM).The predictive ability of the regression models was tested through cross-validation, giving coefficient of determination q2=0.72-0.8. The validation of the models using an external test set proved that the models can be used to predict the activity of newly designed compounds with reasonable accuracy within the applicability domain (q2=0.74-0.8). The models were applied to screen a virtual chemical library of cytisine derivatives, which was designed to have antibacterial activity. The QSAR modeling results allowed to identify a number of cytisine derivatives as effective antibacterial agents against antibiotic-resistant E. coli strains. Seven compounds were selected for synthesis and biological testing. In vitro investigation of the selected cytisine derivatives have shown that all studied compounds are potential antibacterial agents against MDR E. coli strains

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
