PRMT5 plays important roles in diverse cellular processes and is upregulated in several human malignancies. Besides, PRMT5 has been validated as an anticancer target in mantle cell lymphoma. In this study, we found a potent and selective PRMT5 inhibitor by performing structure-based virtual screening and hit optimization. The identified compound 17 (IC50 = 0.33 μM) exhibited a broad selectivity against a panel of other methyltransferases. The direct binding of 17 to PRMT5 was validated by surface plasmon resonance experiments, with a Kd of 0.987 μM. Kinetic experiments indicated that 17 was a SAM competitive inhibitor other than the substrate. In addition, 17 showed selective antiproliferative effects against MV4-11 cells, and further studies indicated that the mechanism of cellular antitumor activity was due to the inhibition of PRMT5 mediated SmD3 methylation. 17 may represent a promising lead compound to understand more about PRMT5 and potentially assist the development of treatments for leukemia indications.

通过基于结构的虚拟筛选和命中优化开发的有效，选择性和细胞活性蛋白精氨酸甲基转移酶5（PRMT5）抑制剂。
PRMT5在多种细胞过程中起着重要作用，并在几种人类恶性肿瘤中被上调。此外，PRMT5已被确认为套细胞淋巴瘤的抗癌靶标。在这项研究中，我们通过执行基于结构的虚拟筛选和命中优化，发现了一种有效的选择性PRMT5抑制剂。鉴定出的化合物17（IC 50 = 0.33μM）对一组其他甲基转移酶表现出广泛的选择性。通过表面等离振子共振实验验证了17与PRMT5的直接结合，K d为0.987μM。动力学实验表明17是除底物以外的SAM竞争性抑制剂。另外17提示对MV4-11细胞具有选择性的抗增殖作用，进一步的研究表明，细胞抗肿瘤活性的机制是由于PRMT5介导的SmD3甲基化的抑制。17可能是一种有前途的先导化合物，可以进一步了解PRMT5，并可能有助于开发白血病适应症的治疗方法。
