Tat-Gap 19是一种针对连接蛋白43 (Cx43) 半通道的肽抑制剂,由HIV-1 Tat蛋白传导域与对应于Cx43第128-136残基的九氨基酸肽连接而成。Tat-Gap 19 (10 µM) 能够抑制初级大鼠肝细胞中由谷氨酸引发的ATP释放,这是Cx43半通道活性的标志。在通过中脑动脉堵塞(MCAO)诱导的小鼠脑缺血再灌注损伤模型中,以25 mg/kg的剂量进行给药,可减少梗死体积。腹腔内注射Tat-Gap 19 (1 mg/kg 每天) 能够减少硫代乙酰胺引起的小鼠肝损伤模型中的纤维化病灶面积及表达α-平滑肌肌动蛋白 (α-SMA) 的肝星状细胞(成纤维细胞的前体)面积,并提高同种小鼠分离的肝细胞中超氧化物歧化酶 (SOD) 活性。

产品描述 | Tat-Gap 19, a peptide inhibitor of connexin43 (Cx43) hemichannels, is derived from the HIV-1 Tat protein transduction domain fused with a nine-amino acid sequence from Cx43 residues 128-136. This compound, at a concentration of 10 µM, effectively suppresses glutamate-induced ATP release in primary rat hepatocytes, indicating inhibition of Cx43 hemichannel activity. Furthermore, Tat-Gap 19 demonstrates therapeutic potential by significantly reducing infarct volume in a mouse cerebral ischemia-reperfusion injury model following middle cerebral artery occlusion (MCAO) at a dosage of 25 mg/kg. Moreover, its intraperitoneal administration at 1 mg/kg per day ameliorates fibrosis and decreases the area of hepatic stellate cells, the precursors to myofibroblasts, expressing α-smooth muscle actin (α-SMA), in a model of thioacetamide-induced liver damage. Additionally, it enhances superoxide dismutase (SOD) activity in hepatic cells from the treated mice, indicating its antioxidative benefits. |

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。
