Synthesis and kinase inhibitory activity of 3'-(S)-epi-K-252a

Bioorg Med Chem Lett. 2002 Oct 21;12(20):2829-31. doi: 10.1016/s0960-894x(02)00638-8.

Abstract

The 3'-epi diastereomer of K-252a was synthesized with the goal of evaluating the stereochemical requirements of the 3'-sugar alcohol on kinase inhibitory activity. Inverting the 3'-alcohol resulted in a 20 nM inhibitor of VEGFR2 and a 1 nM inhibitor of TrkA tyrosine kinase.
