Polymer-assisted solution-phase (PASP) parallel library synthesis was used to discover a piperazinyl glutamate pyridine as a P2Y(12) antagonist. Exploitation of this lead provided compounds with excellent inhibition of platelet aggregation its measured in a human platelet rich plasma (PRP) assay. Pharmacokinetic and physiochemical properties were optimized through modifications at the 4-position or the pyridine ring and the terminal nitrogen of the piperazine ring, leading to compound (4S)4-[(4-[4-(methoxymethyl)piperdin-1-yl]-6-phenylpyridin-2-yl}carbonyl)amino]-5-oxo-5-4-[(pentyloxy)carbonyl]piperazin-1-yl}pentanoic acid 47s with good human PRP potency, selectivity, in vivo efficacy, and oral bioavallability. Compound 47s was selected for further preclinical evaluations.
