Bioorg Med Chem Lett. 2013 Dec 1;23(23):6228-33. doi: 10.1016/j.bmcl.2013.09.094. Epub 2013 Oct 8.

Abstract

The synthesis, SAR, binding affinities and pharmacokinetic profiles are described for a series of cyclohexane-based prolylcarboxypeptidase (PrCP) inhibitors discovered by high throughput screening. Compounds show high levels of ex vivo target engagement in mouse plasma 20 h post oral dose.

Keywords: Inhibitor; Obesity; PrCP; Prolylcarboxypeptidase; Serine protease.
