Biological Activity
CTX-439 (0-10 μM; 6-72 h) inhibits the proliferation of SUM149PT cells with an IC50 of 100.5 nM, induces DNA damage and apoptosis, and downregulates the expression of DNA damage repair genes by inhibiting CDK12 activity[1].
CTX-439 (0-1 μM; 0-24 h) downregulates MCL1 protein levels in SUM149PT and OV90 cells[1].
CTX-439 (100-800 nM; 4-8 h) synergizes with the BCL-2/BCL-xL inhibitor AZD4320 (HY-112416) to rapidly induce apoptosis in SUM149PT and OV90 cells[1].
