10-(2-oxo-2-Phenylethylidene)-10H-anthracen-9-ones as Highly Active Antimicrotubule Agents: Synthesis, Antiproliferative Activity, and Inhibition of Tubulin Polymerization
摘要:
A series of 10-(2-oxo-2-phenylethylidene)-10H-anthracen-9-ones were synthesized and evaluated for interactions with tubulin and for antiproliferative activity against a panel of human and rodent tumor cell lines. The 4-methoxy analogue 17b was most potent, displaying IC50 values ranging from 40 to 80 nM, including multidrug resistant phenotypes, and had excellent activity as an inhibitor of tubulin polymerization (IC50 = 0.52 mu M). Concentration-dependent flow cytometric studies showed that KB/HeLa cells treated with 17b were arrested in the G2/M phases of the cell cycle (EC50 = 90 nM). In competition experiments, 17b strongly displaced [H-3]-colchicine from its binding site in the tubulin. The results obtained demonstrate that the anti proliferative activity is related to the inhibition of tubulin polymerization.

The present invention provides novel anthracene compounds according to the formulae (I) and (II) and also selected anthracene compound compounds. The present invention furthermore provides a process for preparing such anthracene compounds. Also provided are pharmaceutical formulations comprising these anthracene compounds. The anthracene compounds provided are particularly suitable for the treatment and/or prophylaxis of physiological and/or pathophysiological conditions which can be treated by inhibiting tubulin polymerization and/or by inhibiting microtubuli-based motor proteins, in particular various tumor disorders.
