CDK6-IN-2
CDK6-IN-2 is a CDK6 covalent inhibitor with an IC50 of 0.013 μM. CDK6-IN-2 inhibits the proliferation and migration of triple-negative breast cancer cells, and induces cell cycle arrest and apoptosis. CDK6-IN-2 induces ROS accumulation and mitochondrial damage through cellular metabolic reprogramming. CDK6-IN-2 exhibits anti-tumor activity and can be used for the research of triple-negative breast cancer.

Caspase 3 |
CDK6-IN-2 (compound C32) (72 h) selectively inhibits the viability of TNBC and BRCA1-mutant breast cancer cells with an IC50 value ≤ 0.08 μM, while exhibits low activity against normal mammary epithelial cells and ER-positive breast cancer cells[1].
CDK6-IN-2 (0-0.2 μM; 0-72 h) potently inhibits the proliferation and migration of MDA-MB-231 and BT-549 triple-negative breast cancer (TNBC) cells, and induces apoptosis, cell cycle arrest, and intracellular ROS accumulation[1].
CDK6-IN-2 (0-0.20 μM; 72 h) induces mitochondrial damage and dysfunction, including reduced membrane potential and structural abnormalities, in MDA-MB-231 and BT-549 triple-negative breast cancer (TNBC) cells[1].
CDK6-IN-2 (0-0.20 μM; 72 h) inhibits autophagic flux and degradation processes in MDA-MB-231 and BT-549 triple-negative breast cancer (TNBC) cells, which is evidenced by the co-accumulation of LC3II and P62 proteins[1].
