Two structural classes of dual alpha(4)beta(1)/alpha(4)beta(7) integrin antagonists were investigated via solid-phase parallel synthesis. Using an acylated amino acid backbone, lead compounds containing biphenylalanine or tyrosine carbamate scaffolds were optimized for inhibition of alpha(4)beta(1)/VCAM and alpha(4)beta(7)/MAdCAM. A comparison of the structure-activity relationships in the inhibition of the alpha(4)beta(7)/MAdCAM interaction for substituted amines employed in both scaffolds suggests a similar binding mode for the compounds.
