We describe a series of pyrazole and isoxazole analogs as antagonists of the 043 receptor. Compounds showed low to sub-nanomolar potency against alpha(v)beta(3), as well as good selectivity against alpha(IIb)beta(3). In HT29 cells, most analogs also demonstrated significant selectivity against alpha(v)beta(6). Several compounds showed good pharmacokinetic properties in rats, in addition to anti-angiogenic activity in a mouse corneal micropocket model. Compounds were synthesized in a straightforward manner from readily available glutarate precursors. (c) 2006 Elsevier Ltd. All rights reserved.
