(-)-U-50488 hydrochloride ((-)-Trans-(1S,2S)-U-50488 hydrochloride) 是一种选择性 κ-阿片受体 (KOR) 激动剂 (Kd=2.2 nM) 选择性大于 μ 阿片受体 (MOR) (Kd=430 nM)。(-)-U-50488 hydrochloride 比 (+) trans-(1R,2R) U-50488 或 (±) 外消旋混合物 U-50488 对映体更具活性。(-)-U-50488 hydrochloride 对受感染的单核细胞来源巨噬细胞 (MDM) 具有持续有效的抗HIV 作用。
产品描述 | (-)-U-50488 hydrochloride ((-)-Trans-(1S,2S)-U-50488 hydrochloride) is a selective kappa-opioid receptor (KOR) agonist (b>K d =2.2 nM) which is a more selective than μ-opioid receptor (MOR) (b>K d =430 nM). (-)-U-50488 hydrochloride is a more active enantiomer than (+) trans-(1R,2R) U-50488 or the (±) trans-racemic mixture U-50488. (-)-U-50488 hydrochloride has a potent and sustained anti- HIV effect in fected blood monocyte-derived macrophages (MDM) [1]. |
体外活性 | (-)-U-50488 hydrochloride (1 pM-100 nM; 7 days) shows a concentration-dependent inhibition of HIV-1 expression, the maximal inhibition at 10 13 M (approximately 73% suppression) in acutely infected blood monocyte-derived macrophages (MDM) [2]. (-)-U-50488 hydrochloride (10 - 13 M; 7-14 days) (10 13 M) markedly inhibits HIV-1 expression both at 7 and 14 days after infection, it has a sustained inhibitory effect on HIV-1 infection in MDM [2]. |
体内活性 | (-)-U-50488 hydrochloride (intraperitoneal injection ; 5mg/kg; 2 hrs before 4% paraformaldehyde (PFA)) acutely induced pMeCP2-S421 (phosphorylation of the methyl-DNA binding protein MeCP2 at Ser421) and Fos selectively in the nucleus accumbens (NAc) without altering MeCP2 levels in any brain region [3]. Animal Model: C57BL/6J mice [1] Dosage: 5 mg/kg Administration: Intraperitoneal injection; single dose; 2 hrs before 4% PFA Result: Induced pMeCP2-S421 in the brain acutely. |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
