Abstract
In search of better antibacterial and anticancer agents, a series of novel 3-(5-((aryl) methyl) isoxazol-3-yl)-4Hchromen- 4-one derivatives was synthesized (4a-4l) by using 4-oxo-4H-chromene-3-carbaldehyde and alkyne via in situ generated nitrile oxide and evaluated for their antibacterial and anticancer activity in vitro. Antibacterial activity was evaluated against three G+ bacterial strains and anticancer activity against breast cancer cell line (MCF-7) and cervical carcinoma cell line (HeLa). Among all the tested compounds, 4j and 4g exhibited potent antibacterial activity against tested grampositive bacterial strains. 4g, 4i and 4j exhibited potent cytotoxic activity against MCF-7 with IC50 values nearer to the standard drug doxorubicin.
