KWZL-7f15
KWZL-7f15 is a dual CDK6/BRD4 inhibitor with an IC50 of 31.81 nM against human CDK6. KWZL-7f15 inhibits the CDK6-RB axis and BRD4-Myc axis, and also acts as a pan-BET inhibitor. KWZL-7f15 exhibits antiproliferative activity against triple-negative breast cancer cells. KWZL-7f15 shows antitumor activity in xenograft mouse models. KWZL-7f15 can be used in studies related to triple-negative breast cancer.

KWZL-7f15 (compound 7f15) exhibited potent cytotoxicity against triple-negative breast cancer (TNBC) cell lines MDA-MB-231 (IC50 = 0.35 μM), BT-549 (IC50 = 2.77 μM), and showed high selectivity with IC50 > 30 μM against normal mammary epithelial MCF-10A cells[1].
KWZL-7f15 (500 nM for CDK4/CycD1 and CDK6/CycD3) acted as a pan-BET and preferential CDK4/CDK6 inhibitor, with IC50 values of 31.81 nM (CDK6), 56.41 nM (BRD4), 37.30 nM (BRD2 BD1+BD2), 34.02 nM (BRD3 BD1+BD2), 31.79 nM (BRD4 BD2), and showed 57.73% inhibition of CDK4/CycD1 and 80.53% inhibition of CDK6/CycD3 at 500 nM[1].
KWZL-7f15 (0.25-1 μM; 12-48 h) modulated protein expression in MDA-MB-231 cells, causing dose- and time-dependent downregulation of BRD4, c-Myc, p-Rb, and Bcl2, and upregulation of Bax and cleaved-caspase 3[1].
KWZL-7f15 (0.25-1 μM; 48 h) induced G0/G1 phase arrest in MDA-MB-231 cells in a dose-dependent manner[1].
KWZL-7f15 induced oxidative stress and DNA damage in MDA-MB-231 cells, increasing intracellular ROS levels, elevating γ-H2AX, suppressing RAD51, and inducing DNA strand breaks[1].
KWZL-7f15 (0.25 μM, 48 h) inhibited cell migration of MDA-MB-231 cells in a wound-healing assay[1].
KWZL-7f15 (0.25 μM, 48 h) inhibited colony formation of MDA-MB-231 cells[1].
