  • (C) In vivo treatment of Tg:Pomc-Pttg;Pomc-eGFP embryos with small-molecule CDK inhibitors (50 μM) 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.)

  • Pharmacological inhibition of either CDK1/2 or E2F1 prevented the induction of the expression of MAD2 by SKP2 overexpression. Notes: (A) Human lung cancer A549 cells were transfected with 2 μg of vector pcDNA3.1 or pcDNA-SKP2 for 48 h, then treated with CDK1/2 inhibitor flavopiridol or E2F1 inhibitor HLM006474 for additional 24 h. Total RNAs were extracted for the detection of the mRNA levels MAD2 by RT-QPCR with GAPDH as internal control. Quantitative analysis are expressed as mean ± SEM. n=3, *P<0.05 vs control. (B) Human lung cancer A549 cells were transfected with 2 μg of vector pcDNA3.1 or pcDNA-SKP2 for 48 h, then treated with CDK1/2 inhibitor flavopiridol or E2F1 inhibitor HLM006474 for additional 24 h. Total proteins were extracted for the detection of the protein levels Skp2 and Mad2 and the phosphorylation of Rb at Ser780 (pRb-S780) by Western blotting. GAPDH served as the loading control. (C) Human lung cancer A549 cells were transfected with 50 nM control or SKP2-specific siRNA with lipofectamine 2000 for 48 h, then treated with CDK1/2 inhibitor flavopiridol or E2F1 inhibitor HLM006474 for additional 24 h. Total proteins were extracted for the detection of the protein levels Skp2 and Mad2 by Western blotting. GAPDH served as the loading control. Abbreviations: MAD2, mitotic arrest deficient 2; SKP2, S-phase kinase-associated protein 2; mRNA, messenger RNA; SEM, standard error of the mean; Rb, retinoblastoma; siRNA, small interfering RNA.

Flavopiridol displays less activity against unrelated kinases such as MAP, PAK, PKC, and EGFR with IC50 of >14 μM. Flavopiridol significantly inhibits the colony growth of HCT116, A2780, PC3, and Mia PaCa-2 cells with IC50 of 13 nM, 15 nM, 10 nM and 36 nM, respecitively. [1] Flavopiridol also potently inhibits the activity of Glycogen synthase kinase-3 (GSK-3) with an IC50 of 280 nm. [2] Compared with other CDKs, Flavopiridol inhibits the activity of CDK7 less potently with IC50 of 875 nM. Flavopiridol (0.5 μM) inhibits both pSer807/811 Rb and pThr199 NPM, whereas mild changes are observed at pThr821 Rb. Flavopiridol also decreases the overall RNA polymerase II level, as well as the phosphorylation of RNA polymerase II on the CTD repeats at Ser2 Ser5. [3] As a broad spectrum CDK inhibitor, Flavopiridol can inhibit cell cycle progression in either G1 or G2. Flavopiridol (0.3 μM) induces G1 arrest in either MCF-7 or MDA-MB-468 cells by inhibition of the CDK4 or CDK2 kinase activity. [4] Flavopiridol exhibits potent cytotoxicity against a wide variety of tumor cell lines with IC50 values ranging form 16 nM for LNCAP to 130 nM for K562. [5]

体内試験 Administration of Flavopiridol at 7.5 mg/kg for 7 days displays slight antitumor activity against P388 murine leukemia, resulting in %T/C value of 110, and active against the human A2780 ovarian carcinoma implanted sc in nude mice, producing 1.5 log cell kill (LCK). [5] Flavopiridol treatment at 1-2.5 mg/kg for 10 days significantly suppresses collagen-induced arthritis in mice in a dose-dependent manner, by inhibiting synovial hyperplasia and joint destruction, whereas serum concentrations of anti-collagen type II (CII) Abs and proliferative responses to CII are maintained. [6] In the p21-intact Hct116 xenografts in nude mice, administration of CPT-11 (100 mg/kg) followed by Flavopiridol (3 mg/kg) 7 and 16 hours later significantly inhibits tumor regression by 86% and 82%, respectively, displaying >2 fold inhibition compared with CPT-11 alone by 40 %. The combination produces ~30% complete response rate (CR) in contrast to CPT-11 alone where no CR is found. [7]

For CDK2/cyclin E kinase assay, kinase reactions consist of 5 ng of baculovirus expressed GST-CDK2/cyclin E (human) complex, 0.5 μg GST-RB fusion protein (amino acids 776-928 of retinoblastoma protein), 0.2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL kinase buffer (50 mM Hepes, pH 8.0, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT). For CDK4/cyclin D1 kinase assay, kinase reactions consist of 150 ng of baculovirus expressed GST-CDK4/cyclin D1 (human), 280 ng of Stag-cyclin D1, 0.5 μg GST-RB fusion protein (amino acids 776-928 of retinoblastoma protein), 0.2 μCi [γ-33P]ATP, 25 μM ATP in 50 μL kinase buffer (50 mM Hepes, pH 8.0, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT). Reactions are incubated for 45 minutes for CDK1 and CDK2, or 1 hour for CDK4 at 30 °C and stopped by the addition of cold trichloroacetic acid (TCA) to a final concentration 15%. TCA precipitates are collected onto GF/C unifilter plates using a Filtermate universal harvester and the filters are quantitated using a TopCount 96-well liquid scintillation counter. Flavopiridol is dissolved at 10 mM in dimethylformamide (DMF) and evaluated at six concentrations, each in triplicate. The final concentration of DMF in the assay = 2%. IC50 values are derived by nonlinear regression analysis and have a coefficient of variance = 16%. To assay Flavopiridol activity on CDK6, a filter-binding assay is established. The following are combined in the reaction mixture: 2 μL of CDK6 (0.7 mg/μL), 5 μL of histone H1 (6 mg/mL), 14 μL of kinase buffer (60 mM β-glycerophosphate, 30 mM p-nitrophenyl phosphate, 25 mM MOPS (pH 7.0), 5 mM EGTA, 15 mM MgCl2, 1 mM DTT, 0.1 mM Na-vanadate), 3 μL of increasing concentrations of Flavopiridol diluted in 50% DMSO, and 6 μL of 33P-ATP (1 mCi/mL) in nonradioactive ATP at 90 μM concentration (final concentration: 15 μM). The assay is initiated by the addition of 33P-ATP. The reaction is incubated for 20 minutes at 30°C. A 25 μL aliquot of the supernatant is then spotted onto Whatman P81 phosphocellulose paper. Filters are washed 5 times with 1% phosphoric acid solution. Wet filters are counted in the presence of 1 mL of scintillation fluid. Cdk9 activity is measured using 50 nM of recombinant Cdk9/cyclin T in 50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM DTT, 3 μM Na3VO4, 150 μM RNA polymerase CDT peptide and 80 μM ATP. Cdk7 assay is performed in the same buffer using 37 nM of purified kinase in the presence of 200 μM ATP and 10 μM myelin binding protein as a substrate. The potency of Flavopiridol toward CDK9 and CDK7 is determined using either a strong anion exchanger (Dowex 1-X8 resin, formate form)-based assay or a scintillation proximity assay. IC50 values are calculated from the dose-response curves.
