demethylase to catalyze the demethylation of H3K4 and H3K9 and thus is an attractive target for therapeutic cancer. Starting with a high micromolar compound 17i, structure-based optimization of novel indole derivatives is described by a bioelectronic isosteric strategy. Grounded by molecular modeling, medicinal chemistry has efficiently yielded low nanomolar LSD1 inhibitors. One of the compounds, B35, exhibited
赖氨酸特异性去甲基化酶 1 (LSD1) 是一种 FAD 依赖性组蛋白去甲基化酶,可催化 H3K4 和 H3K9 去甲基化,因此是治疗癌症的一个有吸引力的靶点。从高微摩尔化合物17i开始,通过生物电子等排策略描述了新型吲哚衍生物的基于结构的优化。以分子模型为基础,药物化学有效地产生了低纳摩尔 LSD1 抑制剂。其中一种化合物B35对 A549 细胞表现出优异的 LSD1 抑制作用 (IC 50 = 0.050 ± 0.005 μM ) 和抗增殖作用 (IC 50 = 0.74 ± 0.14 μM )。进一步的PK研究表明化合物B35具有良好的代谢稳定性,po和iv的血浆t 1/2分别为6.27±0.72 h和8.78±1.31 h。此外,抑制剂B35具有很强的抗肿瘤作用和良好的体内安全性。同时,化合物B35调节的基因与癌症中的转录错位以及涉及IGFBP3的PI3K/AKT通路密切相关。总而言之,
