Abstract
Several phenylalanine based inhibitors were synthesized as antagonists of the leukocyte cell adhesion process that is mediated through the interactions of the mucosal addressin cell adhesion molecule (MAdCAM) and the integrin alpha4beta7. Analogues 20, 21, 22 and 24 displayed inhibition of adhesion in a cell based assay in the low micromolar range.
