Potent Dibasic GPIIb/IIIa Antagonists with Reduced Prolongation of Bleeding Time: Synthesis and Pharmacological Evaluation of 2-Oxopiperazine Derivatives
2-oxopiperazine derivatives, possessing basic moieties at the 3- and the 4-positions, were synthesized and evaluated for their abilities to inhibit plateletaggregation and for their effects on bleeding time. Among the compounds, 2-[(3S)-4-[2-[(4-guanidinobenzoyl)amino]acetyl]-3-[3-[(4-guanidinobenzoyl)amino]propyl]-2-oxopiperazinyl]acetic acid (12c) showed a potent inhibitory effect on plateletaggregation and
合成了一系列在3-位和4-位具有碱性部分的2-氧杂哌嗪衍生物,并对其抑制血小板聚集的能力及其对出血时间的影响进行了评估。在这些化合物中,2-[((3S)-4- [2-[(4-胍基苯甲酰基)氨基]乙酰基] -3- [3-[(4-胍基苯甲酰基)氨基]丙基] -2-氧代哌嗪基]乙酸(图12c)显示了对血小板聚集的有效抑制作用,以及功效和出血副作用之间的良好分离。静脉内以1.6 microg / mL / min的剂量注入化合物12c可完全防止豚鼠内皮损伤引起的动脉血栓形成。将出血时间延长至对照值的三倍的12c剂量为5.8 microg / mL / min。这些结果表明,化合物12c在血栓性疾病的临床治疗中可能有用,
