1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 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. 
* <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 C646 is an inhibitor for histone acetyltransferase, and inhibits p300 with a Ki of 400 nM in a cell-free assay. Preferentially selective for p300 versus other acetyltransferases. C646 induces cell cycle arrest, apoptosis and autophagy.
in vitro C646 is an inhibitor for histone acetyltransferase, inhibits p300 with a Ki of 400 nM and is selective versus other acetyltransferases. C646 produces 86% inhibition of p300 in vitro at 10 μM. C646 is a classical reversible p300 inhibitor. C646 treatment (25μM) reduces histone H3 and H4 acetylation levels and abrogates TSA-induced acetylation in cells. [1] C646 (20μM) induces apoptosis in androgen-sensitive and castration-resistant prostate cancer cell lines by interfering with AR and NF-kB pathways. [2] C646 blocks dynamic acetylation of H3K4me3 globally in mouse and fly cells, and locally across the promoter and start-site of inducible genes in the mouse, thereby disrupting RNA polymerase II association and the activation of these genes. [3]
in vivo C646 infused into the ILPFC immediately after weak extinction training enhances the consolidation of fear extinction memory. [4] C646 attenuates mechanical allodynia and thermal hyperalgesia, accompanied by a suppressed COX-2 expression, in the spinal cord. [5]
特徴 Extensively used as a pharmacologic probe in cancer cells. Potential use for prostate and lung cancers.

キナーゼアッセイ Radioactive assay
IC50 values for the putative p300 HAT inhibitors are determined using the direct radioactive assay described above. Reactions are performed in 20 mM HEPES (pH 7.9), and contained 5 mM DTT, 80μM EDTA, 40μg/ml BSA, 100μM H4-15, and 5 nM p300. Putative inhibitors are added over a range of concentrations, with DMSO concentration kept constant (<5%). Reactions are incubated at 30°C for 10 min, then initiated with addition of a 1:1 mixture of 12C-acetyl-CoA and 14C-acetyl-CoA to 20 mM. After 10 min at 30°C, reactions are quenched with 14% SDS (w/v). All concentrations are screened in duplicate. Gels are run, washed, dried, and exposed to a PhosphorImager plate, and production of Ac-H4-15 quantified to obtain IC50s.
細胞アッセイ 細胞株 C3H10T1/2
濃度 ~25 μM
反応時間 1 to 3 hr
実験の流れ Histone acetylation assays in mouse cells. C3H10T1/2 mouse fibroblasts are grown in DMEM with 10% FCS at 37°C with 6% CO2. Confluent cultures are rendered quiescent in DMEM with 0.5% FCS for 18-20 hr prior to treatment. Cells are treated with the following compounds: TSA (10 ng/ml [33 nM]), C646 (25 μM), C37 (25 μM). Antibodies are used at the following concentrations: total H3 (1:10000; ab7834; Abcam); H4K12ac (1:2500; 06-761; Upstate). Rabbit anti-H3K9ac (1:10000) antibodies are generated in-house. Histones are isolated from cells by acid extraction, separated by SDS and acid-urea polyacrylamide gel electrophoresis and analyzed by western blotting.
