for the management of hormone dependent diseases, such as endometriosis and uterine fibroids. Despite its presence on the market since 2018, a thorough NMR analysis of this drug, together with its synthetic intermediates, is still lacking. Hence, with the aim of filling this literature gap, we here performed a detailed NMR investigation, which allowed the complete assignment of the 1H, 13C, and 15N NMR
Elagolix 钠盐是第一个上市的口服活性非肽类促性腺激素释放激素受体拮抗剂 (GnRHR-ant),用于治疗激素依赖性疾病,例如子宫内膜异位症和子宫肌瘤。尽管该药物自 2018 年上市以来,仍缺乏对该药物及其合成中间体的全面核磁共振分析。因此,为了填补这一文献空白,我们在这里进行了详细的核磁共振研究,从而实现了 1H、13C 和 15N NMR 信号的完整分配。在构象分析的支持下,这些数据允许确定两种阻转异构体的立体化学特征,可在溶液中检测到。此外,这些后者也通过基于纤维素的手性 HPLC 检测到,从通过针对报告的已实施合成程序制备的样品开始。总的来说,这些结果有助于进一步理解药物发现中的阻转异构现象,并可用于设计安全稳定的类似物,从而提高目标选择性。
