Abstract
A series of alpha(v)beta(3) antagonists based on a thiophene scaffold were synthesized via two routes and evaluated for in vitro biological activity. We have identified several structurally similar antagonists with different selectivities towards alpha(IIb)beta(3), alpha(v)beta(5) and alpha(5)beta(1) at the cellular level. In addition, these antagonists exerted an antiangiogenic effect in the chick chorioallantoic membrane (CAM) assay.
