Flavopiridol HCl Chemical Structure

Molecular Weight(MW): 438.3

Flavopiridol HCl 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. Phase 1/2.

  • (C) In vivo treatment of Tg:Pomc-Pttg;Pomc-eGFP embryos with small-molecule CDK inhibitors (50μM) or 0.2% DMSO as control from 18 to 40 hpf. One hundred to one hundred fifty embryos were treated with each compound. Representative images of live embryos are shown with gross morphology (Right) and pituitary Pomc-GFP–positive cells at higher magnification (Left) at 40 hpf. Embryos exposed to flavopiridol developed early developmental defect before pituitary POMC cell ontogeny occurs. (D) Relative expression of pituitary Pomc-eGFP fluorescence analyzed using Volocity 5.2 software (Improvision; mean ± SE of relative expression, n = 7). (E) R-roscovitine specifically suppresses expansion of pituitary POMC cells overexpressing zPttg from 18 to 48 hpf. Double transgenic Tg:Pomc-Pttg;Prl-RFP embryos were generated by breeding Tg:Pomc-Pttg fish with a previously generated PRL-RFP transgenic line, in which RFP was targeted to pituitary lactotrophs by a zebrafish Prolactin promoter (34). Representative fluorescent microscopy of pituitary POMC-eGFP (a and b) and PRL-RFP (c and d) expression in live Tg:Pomc-Pttg; Pomc-eGFP and Tg:Pomc-Pttg;Prl-RFP embryos treated with 0.2% DMSO (a and c) or 50 μM R-roscovitine (b and d). (F) Relative expression of pituitary POMC-eGFP or PRL-RFP fluorescence were analyzed (mean ± SE of relative expression; n = 10). Results represent one of three similar experiments;*P < 0.02 and **P < 0.000005. (Scale bar, 50 μm.)

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. [1] Flavopiridol induces G1 arrest with inhibition of CDK2 and CDK4 in human breast carcinoma cells in a time and concentration dependent manner. [2] 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). [3] 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. [4] A recent study shows Flavopiridol treatment induces a substantial AKT-Ser473 phosphorylation in human glioblastoma T98G cell line. [5]

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. [4] 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.[6]

Protocol

Kinase Assay:[1]
+ Expand

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.

  • Concentrations: 0, 100 500, 5000 nM
  • Incubation Time: 14 hours
  • Method: Cells grown at a density of 1 × 106 cells/mL are exposed to Flavopiridol for different concentrations and time periods. DNA is extracted. Briefly, cells are washed once with cold phosphate-buffered saline (PBS) and lysed with 3 mL lysis buffer (5 mM Tris-HCL [pH 7.5]; 20 mM EDTA; 0.5% Triton X-100) for 15 minutes at 4 °C. The chromatin of the cell lysates is isolated by centrifugation (20 minutes at 26,000g, 4 °C). The supernatants containing small DNA fragments are extracted sequentially with phenol, phenol:chloroform (1:1), and chloroform. Nucleic acids are precipitated in 0.5 M NaCl, 90% ethanol at -20 °C overnight. RNA is then digested by bovine RNAaseA (60 μg/mL). After sequential reextraction and reprecipitation, DNA is dissolved in 10 mM Tris-HCL (pH 7.5), 1 mM EDTA, 0.5% sodium dodecyl sulfate (SDS) before electrophoresis on 1.6% agarose gel.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Concentration
    Volume
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1
    V1
    C2
    V2

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Molecular Weight Calculator

Molecular Weight Calculator

Enter the chemical formula of a compound to calculate its molar mass and elemental composition:

Total Molecular Weight: g/mol

Tip: Chemical formula is case sensitive. C10H16N2O2 c10h16n2o2

Instructions to calculate molar mass (molecular weight) of a chemical compound:

To calculate molar mass of a chemical compound, please enter its chemical formula and click 'Calculate'.

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.
