demethylase 1 (LSD1) is associated with different cancer types, and it is increasingly recognized as a potential therapeutic target in oncology. Here, utilizing core hopping and conformational restriction strategies, we designed and synthesized a series of coumarin analogs that were shown to be potent LSD1 inhibitors in the enzyme assay. Furthermore, several potent compounds were selected to evaluate their
赖氨酸特异性组蛋白去甲基化酶 1 (LSD1) 的异常表达与不同的癌症类型有关,它越来越被认为是肿瘤学中的潜在治疗靶点。在这里,利用核心跳跃和构象限制策略,我们设计并合成了一系列香豆素类似物,这些类似物在酶测定中被证明是有效的 LSD1 抑制剂。此外,选择了几种有效的化合物来评估它们对 LSD1 高表达的 A549 细胞和 MGC-803 细胞的抗增殖活性。其中,YX10对A549细胞和MGC-803细胞具有抗克隆作用,IC 50值分别为 1.52 ± 0.16 和 0.98 ± 0.18 μM。建模表明,抑制剂将与位于 Asp555 和 Lys661 关键残基周围的蛋白质活性位点结合。同时,初步的成药性评估表明,化合物YX10在 10 μM 时表现出良好的肝微粒体和中等血浆稳定性,对细胞色素 P450 异构体的抑制活性较弱。所有结果表明,化合物YX10可以代表一种有前途的先导化合物,有待进一步开发。
