Abstract

The ubiquitous methyltransferases employing SAM as the methyl donor have emerged as potential targets in many disease treatments, especially in Anticancer. Therefore, developing SAM-competitive inhibitors of methyltransferases is of great interest to the drug research. To explore this direction, herein, we rationally designed a series of nucleoside derivatives as potent PRMT5 inhibitors with novel scaffold. The representative compounds A2 and A8 exhibited highly potent PRMT5 inhibition activity as well as good selectivity over other PRMTs and PKMTs. Further cellular experiments revealed that compounds A2 and A8 potently reduced the level of sDMA and inhibited the proliferation of Z-138 and MOLM-13 cell lines by inducing Apoptosis. Moreover, compounds A8 which had favorable pharmacokinetic properties exhibited potent antitumor efficacy without the loss of body weight in a subcutaneous MOLM-13 xenograft model. In summary, our efforts provided a series of novel nucleoside analogs as potent PRMT5 inhibitors and may also offer a new strategy to develop SAM analogs as other methyltransferases' inhibitors.
