Lysine-specific demethylase 1 (LSD1/KDM1A) is a promising therapeutic target for the treatment of cancers. Several derivatives of tranylcypromine (2-phenylcyclopropylamine) have been developed as LSD1 inhibitors. One such derivative is ; however, this compound has a high hERG channel inhibitory activity and a low microsomal stability, making it unsuitable as a drug candidate. Here, using an hERG inhibition prediction model, we designed, synthesized, and evaluated a novel series of derivatives characterized by modifications of the benzyloxy and piperazine groups. Among the synthesized derivatives, a compound possessing 2-fluoropyridine and 2,8-diaza-spiro[4.5]decane groups (compound ) showed the most desirable activities, and its eutomer, , was isolated by the optical resolution of . In addition to potent LSD1 inhibitory activity, exhibited desirable hERG channel inhibition and microsomal stability profiles.
赖氨酸特异性去甲基化酶1（LSD1/KDM1A）是一种很有前景的癌症治疗靶点。反苯环丙胺（2-苯基环丙胺）的几种衍生物已被开发为LSD1抑制剂。其中一种衍生物是 ；然而，该化合物具有较高的人乙醚相关基因（hERG）通道抑制活性和较低的微粒体稳定性，使其不适宜作为候选药物。在此，我们使用hERG抑制预测模型，设计、合成并评估了一系列以苄氧基和哌嗪基团修饰为特征的新型衍生物。在合成的衍生物中，一种具有2-氟吡啶和2,8-二氮杂螺[4.5]癸烷基团的化合物（化合物 ）表现出最理想的活性，其优映体 通过 的光学拆分被分离出来。除了具有强大的LSD1抑制活性外， 还表现出理想的hERG通道抑制和微粒体稳定性特征。
