Novel representative of the important group of biologically active benzosuberones bearing 2, 4-thiazolidenone moiety was synthesized as potential Anticancer agents (6a-j). These compounds were synthesized in good yields from Knoevenagel condensation of compounds 2a-b with thiazolidenone derivatives 3a-e in the presence of sodium acetate and glacial acetic acid. The in vitro cytotoxicity of these compounds was evaluated against different human Cancer cell lines (A549, HeLa, MDA-MB-231, MCF-7) and normal cell line, HEK293. Compound 6a exhibited promising cytotoxicity with IC₅₀ values ranging from 2.98 to 13.34 μM against all the tested Cancer cell lines, HeLa, A549, MCF-7 and MDA-MB-231, while compound 6g showed potent cytotoxicity against human breast adenocarcinoma cell line (MCF-7, IC₅₀ value of 1.91 μM).
