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 as measured in a human platelet rich plasma (PRP) assay. Pharmacokinetic and physiochemical properties were optimized leading to compound (4S)-4-[({4-[4-(methoxymethyl)piperidin-1-yl]-6-phenylpyridin-2-yl}carbonyl)amino]-5-oxo-5-{4-[(pentyloxy)carbonyl]piperazin-1-yl}pentanoic acid 22J with good human PRP potency, selectivity, in vivo efficacy and oral bioavailability.
聚合物辅助溶液相(PASP)平行库合成法被用于发现一种哌嗪基 - 谷氨酸 - 吡啶作为P2Y(12)拮抗剂。对该先导化合物的开发得到了在人富血小板血浆(PRP)试验中对血小板聚集具有优异抑制作用的化合物。对其药代动力学和物理化学性质进行了优化,得到了化合物(4S)-4-[({4-[4-(甲氧基甲基)哌啶-1-基]-6-苯基吡啶-2-基}羰基)氨基]-5-氧代-5-{4-[(戊氧基)羰基]哌嗪-1-基}戊酸22J,其在人PRP中具有良好的效力、选择性、体内疗效和口服生物利用度。
