描述 Flavopiridol is a pan CDK inhibitor with IC50 value of 30nM, 40nM, 20-40nM, 60nM, 875nM and 20nM for CDK1, 2, 4, 6, 7, 9 (measured by in vitro kinase assays), respectively[1][2].

It can inhibit the whole cell cycle progression through a variety of mechanisms related to CDK inactivation including:

1. Inhibition of CDK4/6 with cyclin D leads to decreased level of pRb-p107 and p130, as well as inactivation of E2F and stop in G1 progression;

2. Inhibition of cdk2 accompanied with cyclin A or E leads to further decreased phosphorylation and inactivation of Rb, as well as inactivation of E2F, and results in retardation in cell cycle progression through the S-phase and accumulation in G1 and G2;

3. Inhibition of CDK1 accompanied with cyclin A or B leads to inhibition of activation of topoisomerase activators, of lamin proteoglycans histone 1 protein and chromatin condensation, as well as results in retardation in cell cycle progression through S-phase and accumulation in G2 phase;

4. Inhibition of cdk7 accompanied with cyclin H complexes leads to reduced activation of cdk’s, such as CDK4 with cyclin D or CDK1 with cyclin B, and reduced activation of RNA polymerase;

5. Flavopiridol may directly influence expression of cyclin D1 and D3 or participate directly in the control of transcription and activation of RNA-polymerase.

Flavopiridol is able to induce apoptosis of tumor cells, including leukemia cells, head and neck tumors, breast carcinomas and non-small cell lung carcinoma cell lines, as well as normal cells in vitro after 6–48h with concentration ranging in 0.1–0.4uM[3].

Intraperitoneal treatment of 5mg/kg flavopiridol for 12 days showed antitumor activity in subcutaneous HN12 xenograft mice[4].

Clinical studies of flavopiridol of treatement for advanced solid tumors, ALL, AML, CLL, CML, mantle cell lymphoma, multiple myeloma, non-Hodgkin and other lymphomas, advanced sarcomas, breast, esophageal, head and neck, kidney, ovarian, pancreatic, gastric carcinomas and NSCLC are undergoing[5].
作用机制 Flavopiridol is an ATP-competitive inhibitor[6].
