Abstract

2-Phenyl-pyrimidine-4-carboxamide analogs were identified as P2Y12 antagonists. Optimization of the carbon-linked or nitrogen-linked substituent at the 6-position of the pyrimidine ring provided compounds with excellent ex vivo potency in the platelet aggregation assay in human plasma. Compound 23u met the objectives for activity, selectivity and ADMET properties.

Keywords: Antiplatelet; Antithrombotic; GPCR antagonist; P2Y(12) antagonist; P2Y(12) receptor.
