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

体外研究:
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.
