overcome such issues, we aimed to identify novel, small-molecule hGnRH-R antagonists. This led to the discovery of compound BAY 1214784, an orally available, potent, and selective hGnRH-R antagonist. Altering the geminal dimethylindoline core of the initial hit compound to a spiroindoline system significantly improved GnRH-R antagonist potencies across several species, mandatory for a successful compound
子宫肌瘤的生长是性激素依赖性的,并且通常与高度致残的症状有关。大多数治疗选择包括控制这些激素的作用,最终阻断增殖性雌激素信号传导(即,人类促性腺激素释放激素受体[hGnRH-R]活性的口服避孕药/拮抗剂)。然而,完全的hGnRH-R阻断会导致更年期症状并影响骨矿化,从而限制了治疗时间或要求使用雌激素补充疗法。为了克服这些问题,我们旨在鉴定新颖的小分子hGnRH-R拮抗剂。这导致了化合物BAY 1214784的发现,该化合物为口服有效,有效的选择性hGnRH-R拮抗剂。将最初命中化合物的双甲基二氢吲哚啉核心改变为螺二氢吲哚系统,可显着提高跨多个物种的GnRH-R拮抗剂效价,这是成功实现体内化合物优化的必要条件。在一项针对绝经后妇女的首次人体研究中,每天使用BAY 1214784进行的治疗有效地降低了血浆黄体生成素的水平,最高可降低49%,同时还具有较低的药代动力学变异性和良好的耐受性。
