Potent kinase inhibitors containing N-aryl bonds play a crucial role for enzyme inhibition. Hence, the
present investigation was carried out to evaluate the antifungal activity of N-aryl amides of
pyrido[1,2-a]pyrimidin 2-ones. The synthesized compounds were evaluated for their in vitro antifungal
activity against Aspergillus niger and Candida albicans by the disc diffusion method. All the compounds
showed significant antifungal activity. Further, the docking studies were carried out against the active
site of 1NMT and 1KS5 fungi protein. The whole compounds showed great binding affinity and
possess bioavailability. DFT/B3LYP technique using the 6-31G basis set at gaseous phase all the
compounds were optimized and the HOMO-LUMO energies also calculated. Furthermore, in silico
prediction of toxicity and bioactive score values indicates that the compounds are highly reactive.
According to Lipinski’s “rule of five,” all the compounds are expected to be biologically active. It is
expected that these findings will provide clarity regarding molecular recognition and will undoubtedly
aid drug scientists in developing novel drugs in the future.
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.
