the structural differences between isocombretastatin A‐4 (isoCA‐4) bearing a 1,1‐diarylethylene scaffold and the natural Z‐stilbene combretastatin A‐4 (CA‐4), we examined the metabolic profile of isoCA‐4 using humanliver fractions. Seven isoCA‐4 metabolites, resulting from O‐demethylation, hydroxylation of the aromatic rings were identified and synthesized. Evaluation of their cytotoxicity and their
Herein is reported a convergent synthesis of isocombretastatins A, a novel class of potent antitubulin agents. These compounds having a 1,1-diarylethylene scaffold constitute the simplest isomers of natural Z-combretastatins A that are easy to synthesize without need to control the Z-olefin geometry. The discovery of isoCA-4 with biological activities comparable to that of CA-4 represents a major progress in this field.
