Conformationally Constrained ortho-Anilino Diaryl Ureas: Discovery of 1-(2-(1′-Neopentylspiro[indoline-3,4′-piperidine]-1-yl)phenyl)-3-(4-(trifluoromethoxy)phenyl)urea, a Potent, Selective, and Bioavailable P2Y1 Antagonist
摘要:
Preclinical antithrombotic efficacy and bleeding models have demonstrated that P2Y(1) antagonists are efficacious as antiplatelet agents and may offer a safety advantage over P2Y(12) antagonists in terms of reduced bleeding liabilities. In this article, we describe the structural modification of the tert-butyl phenoxy portion of lead compound 1 and the subsequent discovery of a novel series of conformationally constrained ortho-anilino diaryl ureas. In particular, spiropiperidine indoline-substituted diaryl ureas are described as potent, orally bioavailable small-molecule P2Y(1) antagonists with improved activity in functional assays and improved oral bioavailability in rats. Homology modeling and rat PK/PD studies on benchmark compound 31 will also be presented. Compound 31 was our first P2Y(1) antagonist to demonstrate a robust oral antithrombotic effect with mild bleeding liability in the rat thrombosis and hemostasis models.

Heterocyclic products have been accomplished using microwave-assisted [Pd]-catalyzed intramolecular reductive Heck coupling. The protocol found suitable in delivering indolines, oxindoles, and dihydrobenzofurans. Notably, the process was successful in sole aqueous medium and furnished the products bearing a quaternary carbon center.
