Design, Synthesis and Antimicrobial Evaluations of Novel 3,7-Disubstituted 2H-1-benzopyran-2-ones
Asian Journal of Chemistry/Asian journal of chemistry(2020)
Abstract
In present study, a novel class of 3,7-disubstituted 2H-1-benzopyran-2-one derivatives (3xa-3zc) bearing a basic ether side chain at C-7 and a substituted phenyl ring at C-3 of the coumarin ring is synthesized. These compounds have been evaluated for antimicrobial (antibacterial/antifungal) activities. Some of the compounds viz. 3xc, 3xe, 3xf, 3yb, 3yc and 3yf have shown significant antifungal activities against selective strains. Compounds 3xe, 3yb and 3yc with the MIC values of 1.56 μg/mL displayed better antifungal activity than fluconazole against Trichophyton mentagrophytes
