Selective cell adhesion inhibitors: Barbituric acid based alpha4beta7--MAdCAM inhibitors.

ABSTRACT

A novel series of barbituric acid derivatives were identified as selective inhibitors of alpha4beta7 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 alpha4beta1 VCAM.
