General description

A cell-permeable dioxobenzothiazole compound that acts a selective Cdk4 inhibitor (IC50 = 6.0 µM for Cdk4/D1 and >200 µM for Cdk2/A). Exhibit better cytotoxic potential against cancer cells (IC50 = 0.61, 1.08, 0.30, and 1.21 µg/ml against A 549, Col 1, HL-60, and HepG2 tumor cells, respectively) than Cisplatin (Cat. No. 232120).
