Discovery of a synthetic Aminopeptidase N inhibitor LB-4b as a potential anticancer agent

Bioorg Med Chem Lett. 2013 May 1;23(9):2512-7. doi: 10.1016/j.bmcl.2013.03.021. Epub 2013 Mar 13.

Abstract

APN inhibitors have been considered as potential anticancer agents for years. LB-4b is the first synthetic APN inhibitor to be evaluated for both of its anti-invasion and anti-angiogenesis effects. As a potent synthetic APN inhibitor (IC50=850 nM, versus bestatin of 8.1 μM), LB-4b was determined to have more significant block effects to cancer cell invasion and angiogenesis than bestatin. Besides, it is able to be easily synthesized with a high total yield, while the reported synthetic methods of bestatin are much more complex.
