  • In vitro drug sensitivity of (C) quisinostat. Acute lymphoblastic leukemia cell lines (NALM-6, KOPN-30bi) and primary cultured cells established from patient 21 were cultured with the indicated concentrations of anticancer drugs, and viability was measured at 48 hours. Data are presented as percentages of dimethylsulfoxide (DMSO) control and depict the mean 6 standard deviation.

JNJ-26481585 exhibits broad spectrum antiproliferative activity in solid and hematologic cancer cell lines, such as all lung, breast, colon, prostate, brain, and ovarian tumor cell lines, with IC50 ranging from 3.1-246 nM, which is more potent than vorinostat, R306465, panobinostat, CRA-24781, or mocetinostat in various human cancer cell lines tested. [1] A recent study shows that JNJ-26481585 promotes myeloma cell death at low nanomolar concentrations by resulting in Mcl-1 depletion and Hsp72 induction. [2]

体内試験 In an HDAC1-responsive A2780 ovarian tumor screening model, JNJ-26481585 dosing at its maximal tolerated dose (10 mg/kg i.p. and 40 mg/kg p.o.) for 3 days leads to an HDAC1-regulated fluorescence , which predicts tumor growth inhibition. Furthermore, JNJ-26481585 also shows more potent inhibitory effects on the growth of C170HM2 colorectal liver metastases than 5-fluorouracil/Leucovorin. [1]

HDAC activity assays :

In all cases, full-length HDAC proteins are expressed using baculovirus-infected Sf9 cells. In addition, HDAC3 is coexpressed as a complex with human NCOR2. For assessing activity of HDAC1-containing cellular complexes, immunoprecipitated HDAC1 complexes are incubated with an [3H]acetyl- labeled fragment of histone H4 peptide [biotin-(6-aminohexanoic)Gly-Ala-(acetyl[3H])Lys-Arg-His-Arg-Lys-Val-NH2] in a total volume of 50μL enzyme assay buffer (25mM HEPES (pH 7.4), 1 M sucrose, 0.1 mg/mL BSA and 0.01% (v/v) Triton X-100). Incubation is performed for 45 minutes at 37 °C (immunoprecipitates) or 30 min at room temperature. Before addition of substrate, HDAC inhibitors are added at increasing concentrations and preincubated for 10 minutes at room temperature. After incubation, the reaction is quenched with 35μL stop buffer (1 M HCl and 0.4 M acetic acid). Released [3H]acetic acid is extracted with 800μL ethyl acetate and quantified by scintillation counting. Equal amounts of HDAC1 are immunoprecipitated as indicated by Western blot analysis. HDAC1 activity results are presented as mean ± SD of three independent experiments on a single lysate.

  • 実験の流れ: All cell lines are obtained from American Type Culture Collection and cultured according to instructions. The effect of HDAC inhibitors on cell proliferation is measured using an MTT. Proliferation of non–small cell lung carcinoma (NSCLC) cell lines is assessed using an Alamar Blue–based assay. For proliferation of hematologic cell lines, cells are incubated for 72 hours and the cytotoxic activity is evaluated by MTS assay. Data are presented as mean IC50 or IC40 ± SD of at least three independent experiments.

よくある質問(FAQ)

  • 質問1:

    I was thinking of resuspending the powder in 10% hydroxy-propyl-β-cyclodextrin, 25mg/ml mannitol, in sterile water (final pH 8.7). Is this a good vehicle to use? What is the solubility of this chemical in such a vehicle?

  • 回答:

    This vehicle can be used for in vivo studies. The following papers also used this vehicle: 1. http://www.nature.com/leu/journal/v23/n10/full/leu2009121a.html; 2. http://cancerres.aacrjournals.org/content/69/13/5307.long (The solvent contains 10% hydroxypropyl-β-cyclodextrin, 0.8% HCl (0.1 N), 0.9 % NaOH (0.1 N), 3.4% mannitol and pyrogen-free water). The solubility is 2mg/ml.
