CAS No. 131740-09-5
Flavopiridol HCl (NSC 649890 HCl, alvocidib, L86-8275, HMR-1275, DSP-2033) competes with ATP to inhibit CDKs including CDK1, CDK2, CDK4 and CDK6 with IC50 of ~ 40 nM in cell-free assays. It is 7.5-fold more selective for CDK1/2/4/6 than CDK7. Flavopiridol is initially found to inhibit EGFR and PKA. Flavopiridol HCl induces autophagy and ER stress. Flavopiridol HCl blocks HIV-1 replication. Phase 1/2.

Flavopiridol is initially found to inhibit the epidermal growth factor receptor and protein kinase A (IC50 = 21 and 122 μM). Flavopiridol is later shown to inhibit cell proliferation, at more physiologically relevant concentrations (IC50 = 66 nM) when Flavopiridol is tested in the National Cancer Institute Development Therapeutics Program panel of 60 human tumor cell lines.  Flavopiridol induces G1 arrest with inhibition of CDK2 and CDK4 in human breast carcinoma cells in a time and concentration dependent manner.  Short time treatment of Flavopiridol (~12 hours) induce apoptosis in hematopoietic cell lines including SUDHL4, SUDHL6 (B-cell lines), Jurkat and MOLT4 (T-cell lines ), and HL60 (myeloid).  In the clonogenic assay, Flavopiridol functions as a highly potent cytotoxic compound with a mean IC70 with 8 ng/mL in 23 human tumor models.  A recent study shows Flavopiridol treatment induces a substantial AKT-Ser473 phosphorylation in human glioblastoma T98G cell line. 
|In vivo||At the maximal tolerated dose of 10 mg/kg/day administered p.o. on days 1-4 and 7-11, Flavopiridol effects tumor regression in PRXF1337 and tumor stasis lasting for 4 weeks in PRXF1369.  After treatment with 7.5 mg/kg Flavopiridol bolus intravenous (IV) or intraperitoneal on each of 5 consecutive days, 11 out of 12 advanced stage subcutaneous (s.c.) human HL-60 xenografts undergo complete regressions, and animals remain disease-free several months after one course of Flavopiridol treatment. SUDHL-4 s.c. lymphomas treated with flavopiridol at 7.5 mg/kg bolus IV for 5 days undergo either major (two out of eight mice) or complete (four out of eight mice) regression, with two animals remaining disease-free for more than 60 days. The overall growth delay is 73.2%. Daily IV or IP administration of ﬂavopiridol results in peak plasma levels of about 7 µM, followed by a progressive decline to approximately 100 nM in 8 hours.|
Recombinant CDKs Kinase Reactions:CDKs activities are determined in microtiter plates as follows. Forty μg Gst-Rb are mixed with different amounts of Flavopiridol and unlabeled ATP. Reactions are then started by the addition of an ammonium sulfate cut of the S100 fraction obtained from insect cells expressing recombinant human CDKs. The final reaction conditions are 10 mM MgCl2, 50 mM Tris-HCl (pH 7.5), and 1 mM DTT. The final concentration of ATP is adjusted accordingly. Radiolabeled ATP is used as a phosphoryl donor. The reaction is carried out for 2.5 minutes at 30 °C after addition of enzyme and then terminated with the addition of EDTA. The Gst-Rb is then captured with glutathione-Sepharose and the incorporated radioactivity is determined by liquid scintillation counting.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
