NF-56-EJ40 hydrochloride 是一种有效，高亲和力和高度选择性的人 SUCNR1 (GPR91) 拮抗剂，IC50 为 25 nM，Ki 为 33.5 nM，对大鼠 SUCNR1 几乎没有活性。 NF-56-EJ40 hydrochloride 对人源化大鼠 SUCNR1 具有高亲和力，Ki 值为 17.4 nM。
| 产品描述 | NF-56-EJ40 hydrochloride is a potent, high-affinity, and highly selective human SUCNR1 (GPR91) antagonist with an IC50 of 25 nM and a Ki of 33 nM, and shows almost no activity towards rat SUCNR1. NF-56-EJ40 hydrochloride has high affinity for humanized rat SUCNR1 with a Ki value of 17.4 nM. |
| 体外活性 | NF-56-EJ40 hydrochloride is bound deep inside the hydrophobic pocket, with the acid group coordinated by the hydroxyl groups of the conserved residues Y832.64 and Y301.39 on one side, and R2817.39 on the other side. The conserved E181.27 is predicted to form an additional hydrogen bond to the piperazine ring of NF-56-EJ40 hydrochloride. E221.31 and N2747.32 in human SUCNR1 are replaced by K181.31 and K2697.32 in rat SUCNR1. These two amino acid exchanges could prevent the binding of NF-56-EJ40 hydrochloride to rat SUCNR1 owing to steric hindrance. Radioligand-binding studies with human SUCNR1 showed partial agreement with our homology model: the Y301.39F mutant of human SUCNR1, shows reduced binding of NF-56-EJ40. Similar effects are observed with the E181.27K and E181.27R mutants, probably owing to steric clashes of the Lys and Arg residues with NF-56-EJ40 hydrochloride and the loss of a hydrogen bond to its piperazine ring[1]. Human SUCNR1 residues are introduced into rat SUCNR1 to form the double mutant K181.31E/K2697.32N (hereafter denoted humanized rat SUCNR1) (Ki of 17.4 nM and 33.5 nM for human and humanized rat SUCNR1, respectively). NF-56-EJ40 hydrochloride increases the thermal stability of both humanized rat SUCNR1 and human SUCNR1, but not that of rat SUCNR1[1]. |

体内实验配液计算器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。
