产品描述 | NK-252 is a potential activator of Nrf2. It has great Nrf2-activating potential. |
体外活性 | NK-252 shows this effect with higher potency than OPZ based on the fact that the EC2 value (concentration for a 2-fold induction above background), calculated with linear extrapolation from the values above and below the induction threshold, is 20.8 μM for OPZ and 1.36 μM for NK-252. NK-252 has potential as an Nrf2 activator in hepatic cells. The protective effects of OPZ and NK-252 are examined against H2O2-induced cytotoxicity using Huh-7 cells to evaluate their antioxidant properties. The cells treated with OPZ or NK-252 show increased resistance to H2O2-induced cytotoxicity compared with control cells. The luciferase activity in Huh-7.5 cells treated with Oltipraz (OPZ) or NK-252 displays activation of the NAD(P)H quinone oxidoreductase 1 (NQO1)-ARE in a dose-dependent manner. Prototypical Nrf2 activators that include OPZ have been reported to protect microglial cells from H2O2-induced cytotoxicity [1]. |
体内活性 | Rats on a choline-deficient L-amino acid–defined (CDAA) diet given OPZ or NK-252 show decreased fibrosis scores compared with CDAA control rats. The effects of NK-252 on both fibrosis score and fibrosis area are dose-dependent[1]. Compared with rats fed a normal control diet (naive) (14.7 and 0.72%, respectively), CDAA control rats display approximately 20-fold augmentation of the liver fibrosis area. This augmentation is also drastically reduced by administration of OPZ or NK-252 (5.80% for OPZ, 6.20% for NK-252_low, and 4.97% for NK-252_high). NK-252 alone has no antitumor effect in P388/S- and P388/VCR-mice. The combination therapy with Etoposide and NK-252 significantly increases the life-span of mice inoculated i.p. with P388/VCR compared with the corresponding survival time with Etoposide alone[2]. The combination therapy of Etoposide with NK-252 administered p.o. significantly increases the life-span of mice inoculated i.p. with P388/S compared with the corresponding therapeutic effects with Etoposide alone. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
