Discovery of a novel series of guanidinebenzoates as gut-restricted enteropeptidase and trypsin dual inhibitors for the treatment of metabolic syndrome

Bioorg Med Chem Lett. 2021 May 15:40:127939. doi: 10.1016/j.bmcl.2021.127939. Epub 2021 Mar 11.

Abstract

A novel series of guanidinebenzoate enteropeptidase and trypsin dual inhibitors has been discovered and SAR studies were conducted. Optimization was focused on improving properties for gut restriction, including increased aqueous solubility, lower cellular permeability, and reduced oral bioavailability. Lead compounds were identified with efficacy in a mouse fecal protein excretion study.

Keywords: Enteropeptidase inhibitor; Guanidinebenzoate; Gut-restriction; Trypsin inhibitor.
