A series of novel isocombretapyridines were designed and synthesized based on a lead compound isocombretastatin A-4 (isoCA-4) by replacing 3,4,5-trimethoxylphenyl with substituent pyridine nucleus. The MTT assay results showed that compound 20a possessed the most potent activities against all tested cell lines with IC50 values at nanomolar concentration ranges. Moreover, 20a inhibited tubulin polymerization at a micromolar level and also displayed potent anti-vascular activity in vitro. Further mechanistic studies were conducted to demonstrate that compound 20a could bind to the colchicine site of tubulin,and disrupte the cell microtubule networks, induce G2/M phase arrest, promote apoptosis and depolarize mitochondria of K562 cells in a dose-dependent manner. Notably, 20a exhibited more potent tumor growth inhibition activity with 68.7% tumor growth inhibition than that of isoCA-4 in H22 allograft mouse model without apparent toxicity. The present results suggested that compound 20a may serve as a promising potent microtubule-destabilizing agent candidate for the development of therapeutics to treat cancer.

Further optimization of the trimethoxyphenyl scaffold of parent chalcone compound (2a) by introducing a pyridine ring afforded a series of novel pyridine-chalcone derivatives as potential anti-tubulin agents. All the target compounds were evaluated for their antiproliferative activities. Among them, representative compound 16f exhibited the most potent activity with the IC50 values ranging from 0.023 to 0.045 μM against a panel of cancer cell lines. Further mechanism study results demonstrated that compound 16f effectively inhibited the microtubule polymerization by binding to the colchicine site of tubulin. Moreover, cellular mechanism studies disclosed that 16f caused G2/M phase arrest, induced cell apoptosis and disrupted the intracellular microtubule network. Also, 16f reduced the cell migration and disrupted the capillary-like tube formation of human umbilical vein endothelial cells (HUVECs). Importantly, 16f significantly inhibited tumor growth in H22 xenograft models without apparent toxicity, which was stronger than the reference compound CA-4, indicating that it is worthy to investigate 16f as a potent microtubule-destabilizing agent for cancer therapy.

Renal cell carcinomas (RCC) are refractory to standard therapy with advanced RCC having a poor prognosis; consequently treatment of advanced RCC represents an unmet clinical need. The von Hippel-Lindau (VHL) tumor suppressor gene is mutated or inactivated in a majority of RCCs. We recently identified a 4-pyridyl-2-anilinothiazole (PAT) with selective cytotoxicity against VHL-deficient renal cells mediated by induction of autophagy and increased acidification of autolysosomes. We report exploration of structure-activity relationships (SAR) around this PAT lead. Analogues with substituents on each of the three rings, and various linkers between rings, were synthesized and tested in vitro using paired RCC4 cell lines. A contour map describing the relative spatial contributions of different chemical features to potency illustrates a region, adjacent to the pyridyl ring, with potential for further development. Examples probing this domain validated this approach and may provide the opportunity to develop this novel chemotype as a targeted approach to the treatment of RCC. 2009 American Chemical Society.
