Synthesis of highly potent and selective hetaryl ureas as integrin alpha(V)beta3-receptor antagonists

Bioorg Med Chem Lett. 2002 May 20;12(10):1379-82. doi: 10.1016/s0960-894x(02)00161-0.

Abstract

Solid-phase synthesis and SAR of integrin alpha(V)beta3-receptor antagonists containing a urea moiety as non-basic guanidine mimetic are described. The most potent compounds exhibited IC(50) values towards alpha(V)beta3 in the nanomolar range and high selectivity versus related integrins like alpha(IIb)beta3. For selected examples efficacy in functional cellular assays is demonstrated.
