PJ-68
PJ-68 is a selective PRMT5 inhibitor (IC50 = 517 nM). PJ-68 reduces KLF5 methylation, stability, and downstream target gene expression. PJ-68 induces Apoptosis, inhibits self-renewal capacity, blocks the Wnt/β-catenin signaling pathway by reducing DVL3 expression, and decreases BCR-ABL mRNA and protein levels. PJ-68 serves as a Ligand for Target Protein for PROTAC for the synthesis of PRMT5 PROTAC degraders, such as YZ-17 (HY-189213). PJ-68 inhibits the growth of basal-like breast cancer. PJ-68 prolongs the survival of CML mice. PJ-68 is used for research on basal-like breast cancer and chronic myeloid leukemia.
