Highly potent and selective αVβ3-receptor antagonists: solid-phase synthesis and SAR of 1-substituted 4-amino-1H-pyrimidin-2-ones
摘要:
Solid-phase synthesis and SAR of alpha(V)beta(3)-receptor antagonists based on a NI-substituted 4-amino-1H-pyrimidin-2-one scaffold are described. The most potent compounds exhibited IC50 values towards alpha(V)beta(3) in the nano- to subnanomolar range and high selectivity versus related integrins like alpha(IIb)beta(3). For selected examples efficacy in functional cellular assays was demonstrated. (C) 2002 Published by Elsevier Science Ltd.
