Herein we disclose a series of novel heteroaryl styryl sulfone derivatives as potential anticancer agents. Structure-activity relationships of these newly synthesised compounds were explored with respect to the significance of the position and number of nitrogen atom of the heteroaryl ring for anti-proliferative activity in human cancer cell lines. A lead compound 14f was tested against a panel of cancerous and untransformed cell lines, and found to be highly potent against cancer cells with minimal toxicity in the untransformed cells. Further mechanistic studies uncovered that 14f caused cell-cycle arrest at the G2/M phase and induced apoptosis by targeting CDC25C and Mcl-1 proteins in A2780 ovarian cells.

A series of novel (E)-N-aryl-2-arylethenesulfonamides (6) were synthesized and evaluated for their anticancer activity. Some of the compounds in this series showed potent cytotoxicity against a wide spectrum of cancer cell-lines (IC50 values ranging from 5 to 10 nM) including all drug resistant cell-lines. Nude mice xenograft assays with compound (E)-N-(3-amino-4- methoxyphenyl)-2-(2′,4′,6′-trimethoxyphenyl)ethenesulfonamide (6t) showed dramatic reduction in tumor size, indicating their in vivo potential as anticancer agents. A preliminary drug development study with compound 6t is predicted to have increased blood-brain barrier permeability relative to many clinically used antimitotic agents. Mechanistic studies indicate that 6t and some other analogues disrupted microtubule formation, formation of mitotic spindles, and arrest of cells in mitotic phase. Compound 6t inhibited purified tubulin polymerization in vitro and in vivo and circumvented drug resistance mediated by P-glycoprotein. Compound 6t specifically competed with colchicine binding to tubulin and with similar avidity as podophylltoxin, indicating its binding site on tubulin.
