Biological Activity

Description

Purvalanol A is a potent, and cell-permeable CDK inhibitor with IC50 of 4 nM, 70 nM, 35 nM, and 850 nM for cdc2-cyclin B, cdk2-cyclin A, cdk2-cyclin E, and cdk4-cyclin D1, respectively. Purvalanol A induces endoplasmic reticulum stress-mediated apoptosis and autophagy.

Targets

Cdc2/CyclinB ^[1]	CDK2/CyclinE ^[1]	CDK2/CyclinA ^[1]	CDK4/CyclinD1 ^[1]
4 nM	35 nM	70 nM	850 nM

In vitro

Purvalanol A decreases cell viability in dose-dependent manner in MCF-7 and MDA-MB-231 cell lines. Purvalanol A induces cell viability loss by 50 % in MCF-7 cells but MDA-MB-231 cells sre less sensitive to Purvalanol A (32 % decreases in cell viability). Purvalanol A induces mitochondria-mediated apoptosis in MCF-7 and MDA-MB-231 cells.^[2] Purvalanol A effectively prevents c-Src-mediated transformation by inhibiting both cell cycle progression and c-Src signaling, and effectively suppresses the anchorage independent growth of some human cancer cells in which c-Src is up-regulated. Purvalanol A has a stronger inhibitory effect on the anchorage-independent growth of HT29 and SW480 human colon cancer cells. ^[3]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines MCF-7 and MDA-MB 231 breast cancer cells Concentrations 100 μM Incubation Time 24 h Method Cells are seeded at 10000 density in 96-well plates and treated with various concentrations of Purvalanol A (0-100 μM) for 24 h. Cells are exposed to 10 μL of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltet- razolium bromide dye (5 mg/mL) and are incubated at 37℃ for 4 h. In order to solubilize the formazan crystals 100 μL DMSO is added. Absorbance is determined at 570 nm spectrophotometrically.
