A new series of 4‐aryl‐4H‐chromenes bearing a 5‐arylisoxazol‐3‐yl moiety at the C‐4 position were prepared as potential anticancer agents. The in vitrocytotoxicactivity of the synthesized compounds was investigated against a panel of tumor cell lines including MCF‐7 (breast cancer), KB (nasopharyngeal epidermoid carcinoma), Hep‐G2 (liver carcinoma), MDA‐MB‐231 (breast cancer), and SKNMC (human neuroblastoma)
Background: A new series of quinazoline linked chalcone conjugates were synthesized and evaluated for their in vitro cytotoxicity. Methods: The quinazoline-chalcone derivatives (13a-r) have been prepared by the Claisen-Schmidt condensation of various substituted benzaldehydes (12a-r) with substituted l-(4-(3,4- dihydroquinazolin-4-ylamino)phenyl)ethanone (11a-b) in the presence of aqueous NaOH.
