Summary: | The work reports the synthesis under solvent-free condition using the ionic liquid [Et₃NH][HSO₄] as a catalyst of fifteen novel 3-((dicyclohexylamino)(substituted phenyl/heteryl)-methyl)-4-hydroxy-2
-chromen-2-onederivatives
-
as potential antimicrobial agents. The structures of the synthesized compounds were confirmed by IR, ¹H-NMR,
C-NMR, mass spectral studies and elemental analyses. All the synthesized compounds were evaluated for their
antifungal and antibacterial activity. The compound
bearing 4-hydroxy-3-ethoxy group on the phenyl ring was found to be the most active antifungal agent. The compound
bearing a 2,4-difluoro group on the phenyl ring was found to be the most active antibacterial agent. The mode of action of the most promising antifungal compound
was established by an ergosterol extraction and quantitation assay. From the assay it was found that
acts by inhibition of ergosterol biosynthesis in
. Molecular docking studies revealed a highly spontaneous binding ability of the tested compounds to the active site of lanosterol 14α-demethylase, which suggests that the tested compounds inhibit the synthesis of this enzyme. The synthesized compounds were analyzed for
ADMET properties to establish oral drug like behavior and showed satisfactory results. To establish the antimicrobial selectivity and safety, the most active compounds
and
were further tested for cytotoxicity against human cancer cell line HeLa and were found to be non-cytotoxic in nature. An
acute oral toxicity study was also performed for the most active compounds
and
and results indicated that the compounds are non-toxic. |
