CMP-5 是一种有效的选择性 PRMT5 抑制剂，对 PRMT1，PRMT4 和 PRMT7 酶无活性。CMP-5 在组蛋白的准备过程中，通过抑制 PRMT5 甲基转移酶活性选择性地阻断 S2Me-H4R3。CMP-5 阻断 EBV 驱动的 B 淋巴细胞转化，但对正常 B 细胞没有影响。

CMP-5 is a potent, specific, and selective PRMT5 inhibitor, while displays no activity against PRMT1, PRMT4, and PRMT7 enzymes. CMP-5 selectively blocks S2Me-H4R3 by inhibiting PRMT5 methyltransferase activity on histone preparations. CMP-5 prevents Epstein-Barr virus (EBV)-driven B-lymphocyte transformation but leaving normal B cells unaffected.

CMP-5 (0-100 μM; 24-72 hours) is selectively toxic to lymphoma cells, but shows a limited toxicity to normal resting B lymphocytes even after prolonged incubation.
CMP-5 (40 μM; 24 hours) decreases p-BTK and pY(416)SRC expression in 60A cells when it compares to the DMSO-treated group.
CMP-5 (0-40 μM; 24 hours) preferentially suppresses the proliferation of human Th1 cells over Th2 cells (43 versus 9% inhibition, respectively). The sensitivity of Th1 cells over Th2 cells to PRMT5 inhibition is different, the IC50 values are 26.9 μM and 31.6 μM in human Th1 cells and Th2 cells, respectively.
CMP-5 (25 μM; 24 hours) alone inhibits mouse Th1 cell proliferation by 91%, when added different doses IL-2, IL-2 enhances proliferation and reaches a peak at 5 ng/ml.
