Description | Flavopiridol is a broad spectrum and competitive inhibitor of CDKs, inhibiting CDK1, CDK2, CDK4 with IC50s of 30, 170, 100 nM, respectively. |

In Vitro | Flavopiridol (2 μM) robustly induces a distinct pattern of ER stress in CLL cells that contributes to cell death through IRE1-mediated activation of ASK1 and possibly downstream caspases[1]. Flavopiridol results in potent upregulation of a number of PRGs in treatments lasting 4-24 h. Flavopiridol has and immediate and long-term effect on the expression of several PRGs. In serum starved cells re-stimulated with serum, flavopiridol also inhibits the expression of these genes, but subsequently, JUNB, GADD45B and EGR1 are upregulated in the presence of flavopiridol[2]. |
Kinase Assay | Briefly, lysates containing approximately 3×106 cells are incubated with 50 μM LEVD-AFC (caspase 4 substrate) or LETD-AFC (caspase 8 substrate) containing 10 mM dithiothretiol (DTT). caspase 4 activity is measured one hour after addition of substrate and caspase 8 activity is measured 30 minutes after addition of substrate. Release of free AFC is measured with a Beckman-Coulter DTX 880 multimode detector. |
Cell Assay | The cells treated with flavopiridol are washed after 4 hours with PBS and resuspended in regular growth medium (RPMI 1640) supplemented with 10% human serum and antibiotics for the remainder of the incubation time. In the case of flavopiridol/chloroquine samples, chloroquine is re-added in the fresh media after flavopiridol is washed at 4 hours. For all the other conditions, cells are incubated with the respective drugs for 24 hours continuously. |
