Protein arginine methyltransferases 5 (PRMT5) represents an attractive drug target in epigenetic field for the treatment of leukemia and lymphoma. Here, a series of N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)amide derivatives targeting PRMT5 were designed with structure-based approach and synthesized. Among them, compound 46 showed potent and selective PRMT5 inhibition activity with an
蛋白质精氨酸甲基转移酶5(PRMT5)在表观遗传学领域代表了一种有吸引力的药物靶标,用于治疗白血病和淋巴瘤。在这里,基于结构的方法设计并合成了一系列靶向PRMT5的N-(3-(3,4-二氢异喹啉-2(1 H)-基)-2-羟丙基)酰胺衍生物。其中,化合物46表现出有效且选择性的PRMT5抑制活性,IC 50为8.5 nM,与I期临床试验PRMT5抑制剂GSK-3326595大致相当(IC 50 = 5.5 nM)。化合物46在MV4-11细胞中也显示出明显的抗增殖活性(GI 50 = 18 nM)和MV4-11小鼠异种移植模型的抗肿瘤活性。该分子可以作为探测PRMT5生物学功能的优秀工具化合物。
