Summary
Purvalanol A is a potent CDK inhibitor, which inhibits cdc2-cyclin B, cdk2-cyclin A, cdk2-cyclin E, cdk4-cyclin D1, and cdk5-p35 with IC 50 s of 4, 70, 35, 850, 75 nM, resepctively.
IC50 & Target
|
cdc2-cyclin B 4 nM (IC 50 ) |
cdk2-cyclin E 35 nM (IC 50 ) |
cdk2-cyclin A 70 nM (IC 50 ) |
cdk4-cyclin D1 850 nM (IC 50 ) |
cdk5-p35 75 nM (IC 50 ) |
erk1 9000 nM (IC 50 ) |
In Vitro
Purvalanol A inhibits cdc28 (S. cerevisiae) and erk1 with IC 50 s of 80 and 9000 nM. Purvalanol A shows inhibitory activities against the NCI panel of 60 human tumor cell lines, with average GI50 of 2 μM; two cell lines show an -20-fold increase in sensitivity to purvalanol A: the KM12 colon cancer cell line with a GI 50 of 76 nM and the NCI-H522 non–small cell lung cancer cell line with a GI 50 of 347 nM [1] . Purvalanol A is a 2.5-fold more potent inhibitor of CDK2, but also inhibits DYRK1A potently and a number of other protein kinases in the low micromolar range. Purvalanol A inhibits MKK1, MAPK2/ERK2, JNK/SAPK1c with IC 50 s of 80, 26, 84 μM [2] . Purvalanol A selectively inhibits the phosphorylation of cellular proteins. Purvalanol A prevents the increases of the contents of cyclins D and E during serum-induced G1 phase progression. Purvalanol A does not inhibit transcription under cell-free conditions [3] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
