Abstract

This letter describes the development of a series of potent and selective small molecule Legumain inhibitors suitable as chemical probes for in vitro experiments. Our previous research had identified a dipeptide inhibitor utilizing a semi-reversible cyano warhead that generated 2, a cell active inhibitor. This work explores an alternative P2-P3 linker and further SAR exploration of the P3 group which led to the identification of 16i, a highly potent inhibitor with excellent physiochemical properties.

Keywords
