30.0mg/ml Taking the 1 mL working solution as an example, add 300 μL of 100 mg/ml clarified propylene glycol stock solution to 50 μL of Tween 80, mix evenly to clarify it; then continue to add 650 μL of D5W 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 Droxinostat (NS 41080) is a selective inhibitor of HDAC, mostly for HDACs 6 and 8 with IC50 of 2.47 μM and 1.46 μM, greater than 8-fold selective against HDAC3 and no inhibition to HDAC1, 2, 4, 5, 7, 9, and 10.
in vitro Droxinostat is originally identified as a sensitizer of PPC-1 cells to FAS and TRAIL by downregulating the expression of c-Fas-associated death domain-like interleukin-1-converting enzyme-like inhibitory protein (c-FLIP). [1] In PPC-1 cells cultured in suspension but not adherent conditions, Droxinostat (20 μM–60 μM) sensitizes cells to anoikis by initially activating caspase 8 with subsequent activation of the mitochondrial pathway. Similarly, Droxinostat also sensitizes other cancer cell lines including PC-3, DU-145, T47D, and OVCAR-3, but not LNCaP or MB-MDA-468, to anoikis or CH-11-induced apoptosis. [2] However, the direct targets of Droxinostat remains enigma until recently. It is revealed that in histone deacetylases (HDAC) isoform 1-10, Droxinostat selective inhibits HDAC3, 6, and 8, with IC50 values of 16.9 μM, 2.47 μM, and 1.46 μM, respectively, without inhibiting other HDAC members (IC50 > 20 μM). [3] In MCF-7 breast cancer cells, Droxinostat (10 μM–100 μM) sensitizes cells to apoptosis by decreasing c-FLIPL and c-FLIPS expression, reducing cell survival, and inducing apoptosis. [4]
in vivo In SCID mice models, Droxinostat (30 μM)-treated PPC-1 cells results in decreased distant tumor formation than untreated cells. [2]
特徴 Selective inhibitor of HDAC3, HDAC6,and HDAC8.

プロトコル(参考用のみ)

キナーゼアッセイ HDAC Inhibition Assay
HDAC inhibition is assessed using the CycLex HDACs fluorometric assay according to the manufacturer's protocol and using crude nuclear extract from HeLa cells (principally HDAC1 and HDAC2). The relative activity is expressed as (fluorescence intensity of treated samples/fluorescence intensity of controls) × 100
細胞アッセイ 細胞株 PPC-1 cells
濃度 0–100 μM, dissolved in DMSO (final concentration of DMSO is 0.5%)
反応時間 24 hours
実験の流れ PPC-1 cells (1 × 104) are seeded overnight into 96-well flat-bottomed plates in 100 μL of medium containing 2.5% FCS. The next day, Droxinostat is added. CH-11 antibody (100 ng/mL) is then added and the cells are incubated for 24 hours before assessing cell viability by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) dye reduction assay.
