Prostacyclin controls cardiovascular function via activation of the prostacyclin receptor. Decreased prostacyclin production occurs in several cardiovascular diseases. However, the clinical use of prostacyclin and its analogues is complicated by their chemical and metabolic instability. A medicinal chemistry program searched for novel nonprostanoid prostacyclin receptor agonists not subject to these
前列环素通过前列环素受体的激活来控制心血管功能。前列环素产生的减少发生在几种心血管疾病中。然而,前列环素及其类似物的临床使用由于其化学和代谢不稳定而变得复杂。一项药物化学程序正在寻找不受这些限制的新型非前列腺素类前列环素受体激动剂。合成具有二苯基吡嗪结构核心的化合物。通过修饰线性侧链优化了代谢稳定性和激动剂效能。化合物12b(MRE-269,ACT-333679)被鉴定为有效且高度选择性的前列环素受体激动剂。用N取代末端羧基-酰基磺酰胺基产生母体化合物26a(selexipag,NS-304,ACT-293987),该化合物具有口服活性,并提供持续的12b血浆暴露。化合物26a被开发用于治疗肺动脉高压,并在3期事件驱动的临床试验中显示出降低复合发病率/死亡率终点的风险。
