Selective cell adhesion inhibitors: Barbituric acid based α4β7—MAdCAM inhibitors

A novel series of barbituric acid derivatives were identified as selective inhibitors of α4β7 MAdCAM (mucosal addressin cell adhesion molecule-1) interactions via a high throughput screening exercise. These inhibitors were optimized to submicromolar potencies in whole cell adhesion assays, retaining their selectivity over other integrins.
