生物活性:
HDAC1/2 and CDK2-IN-1 (compound 14d) is a potent HDAC1, HDAC2 and CDK2 dual inhibitor, with IC50 values of 70.7, 23.1 and 0.80 μM, respectively. HDAC1/2 and CDK2-IN-1 can block the cell cycle and induce apoptosis. HDAC1/2 and CDK2-IN-1 exhibits desirable in vivo antitumor activity.

体外研究:
HDAC1/2 and CDK2-IN-1 (compound 14d) shows excellent antiproliferative activities against H460, A375, HepG2, HCT116 and Hela cells with IC50 values of 1.59, 0.47, 0.86, 0.58 and 1.05 μM, respectively.HDAC1/2 and CDK2-IN-1 (0.5 μM, 48 h) significantly inhibits the migration of H460 and A375 cells.HDAC1/2 and CDK2-IN-1 (0-2 μM, 24 h) significantly blocks the cell cycle in the G2/M phase.HDAC1/2 and CDK2-IN-1 (0-2 μM, 48 h) promotes cancer cell apoptosis in a dose-dependent manner.HDAC1/2 and CDK2-IN-1 (1 μM, 12 h) inhibits CDK2 and HDAC activity, causing cancer cell death.HDAC1/2 and CDK2-IN-1 (1 μM, 24 h) strongly increases ROS levels in A375 cells, causes cancer cell death by improving intracellular ROS levels.
