Abstract:
:A novel series of the biheterocycles-based compounds with core structure distinguished from combretastatin A-4 (1) and colchicine (5) have been synthesized and evaluated as potent anti-mitotic agents. Compound 1-(4'-Indolyl and 6'-quinolinyl)-4,5,6-trimethoxyindoles 13 and 19 showed substantial anti-proliferative activity against various human cancer cell lines, regardless to the tissue origin and the expression of multiple-drug resistance MDR1, with a mean IC(50) value of 38 and 24 nM respectively. Compound 13 (IC(50) = 1.7 μM) also exhibited similar anti-tubulin activities to 1 (IC(50) = 1.8 μM) and displayed strong binding property to the colchicine binding site on the microtubules. Computational modeling analysis revealed that the binding mechanism of compound 13 is similar to that of CA4.
