5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 0 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 550 μL of ddH2O to adjust the volume to 1 mL. 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 Givinostat (ITF2357) is a potent HDAC inhibitor for maize HD2, HD1B and HD1A with IC50 of 10 nM, 7.5 nM and 16 nM in cell-free assays. Phase 2.
in vitro In LPS-stimulated cultured human peripheral blood mononuclear cells (PBMCs), ITF2357 reduces the release of TNFα, IL-1α, IL-1β, and IFNγ, with IC50 of 10-25 nM, respectively. Using the combination of IL-12 plus IL-18, ITF2357 reduces IFNγ and IL-6 production with IC50 of 12.5-25 nM, independent of decreased IL-1 or TNFα. [1] ITF2357 is cytotoxic in multiple myeloma (MM) cell lines (RPMI8226, NCI-H929, JJN3, KMS 11, KMS 12, KMS 18, and KMS 20) and acute myelogenous leukemia (AML) cell lines (HL-60, THP-1, U937, KASUMI, KG-1, and TF-1), with IC50 of 200 nM. ITF2357 activates the intrinsic apoptotic pathway, upregulates p21 and downmodulates Bcl-2 and Mcl-1. ITF2357 inhibits the production of IL-6, VEGF, and IFNγ in mesenchymal stromal cells (MSCs) by 80-95%. [2] ITF2357 favors β-cell survival during inflammatory conditions. ITF2357 at concentrations of 25 and 250 nM increases islet cell viability, enhances insulin secretion, inhibits release of MIP-1α and MIP-2, reduces NO production and decreases apoptosis rates. [3]
in vivo ITF2357 (1-10 mg/kg) reduces LPS-induced serum TNFα and IFNγ by more than 50% in mice. Anti-CD3-induced cytokines are not suppressed by ITF2357 in PBMCs in the circulation in mice. In concanavalin-A-induced hepatitis, ITF2357 (1 or 5 mg/kg) significantly reduces liver damage. [1] ITF2357 (10 mg/kg) significantly prolongs survival of severe combined immunodeficient mice inoculated with the AML-PS in vivo passaged cell line. [2] In a mouse model of closed head injury (CHI), ITF2357 (10 mg/kg) improves neurobehavioral recovery, decreases neuronal degeneration, reduces lesion volume, and induces glial apoptosis. [4]
特徴 An orally active, potent inhibitor of histone deacetylases (HDACs).

プロトコル(参考用のみ)

キナーゼアッセイ Enzymatic Assay for HDAC Inhibitory Activity of Synthetic Compounds
The assay is performed by adding 100 μL substrate (2×105 cpm), 40 μL buffer (50 mM Tris-HCl, pH 8.0, 750 mM NaCl, 5 mM PMSF, 50% glycerol) and 95 μL distilled water to the crude cellular extract (5 μL). ITF2357 (50 μL) is added to test for HDAC inhibition. The mixture is incubated overnight at room temperature and the reaction quenched by adding 50 μL of a solution containing 259 μL 37% HCl and 28 μL acetic acid in 1 mL distilled water. The [3H]acetyl residues released from the substrate are separated by organic extraction with 600 μL of ethyl acetate, 200 μL of the organic phase is added to standard scintillation fluid, and radioactivity is measured by a beta-counter. Inhibition of HDACs is expressed as the concentration inhibiting 50% of the control activity (by comparing the radioactivity of the samples containing inhibitors to that of the control containing cellular crude extract alone).
細胞アッセイ 細胞株 peripheral blood mononuclear cells (PBMCs)
濃度 1 nM - 1 μM
反応時間 24 hours
実験の流れ After washing, the isolated PBMCs are resuspended in RPMI containing 5% FCS at 5×106/mL, added to a 50-mL conical polypropylene tube, and placed at 4 °C overnight. The PBMCs are resuspended the next morning and added to a 96-well flat microtiter plate (100 μL per well). ITF2357 is then added for inhibition studies, and the plates are incubated at 37 °C for 1 hour, after which the cells are stimulated with LPS or other stimulants in a final volume of 200 μL per well. The supernatants are removed after incubation at 37 °C for 24 hours, and frozen at -80 °C until assayed for cytokines.
動物実験 動物モデル Mice. For LPS induction of serum cytokines: BALB/c; for anti-CD3-induced cytokines: CD1; for concanavalin A (Con A)-induced acute hepatitis: BALB/c or C57Bl6.
投薬量 0.01-50 mg/kg
投与方法 By gavage in 100 μL water.
