4.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 80 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Quisinostat (JNJ-26481585) 2HCl is a novel second-generation HDAC inhibitor with highest potency for HDAC1 with IC50 of 0.11 nM in a cell-free assay, modest potent to HDACs 2, 4, 10, and 11; greater than 30-fold selectivity against HDACs 3, 5, 8, and 9 and lowest potency to HDACs 6 and 7. Phase 2.
in vitro 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]
in vivo 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]
特徴 An orally bioavailable, second-generation, hydroxamic acid-based HDAC inhibitor.

キナーゼアッセイ 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.
細胞アッセイ 細胞株 NCL-H2106, Colo699 and LNCAP cells
濃度 0-300 nM
反応時間 24 hours
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.
動物実験 動物モデル HCT116 human colon carcinoma cells are injected s.c. into the inguinal region of athymic male NMRI nu/nu mice, C170HM2 cell suspensions are injected into the peritoneal cavity of male MFI nude mice.
投薬量 ≤10 mg/kg
投与方法 Administered via both p.o. and i.p.
