产品描述 | Tyrphostin 8(4-Hydroxybenzylidenemalononitrile) is a potent GTPase inhibitor that inhibits EGFR kinase with an IC50 of 560 μM.Tyrphostin 8 inhibits protein serine/threonine calmodulin phosphatases (IC50=21 μM), enhances transferrin receptor-mediated transcytosis in Caco-2 cells, and increases the hypoglycemic effect of oral insulin-transferrin. hypoglycemic effect. |
靶点活性 | EGFR:560 μM (IC50), Calcineurin phosphatase:21 μM (IC50) |
体外活性 | Pretreated for 20 minutes at concentrations ranging from 10 to 100 μM, Tyrphostin 8 blocks Carbachol-initiated PKCδ tyrosine phosphorylation and ERK1/2 activation in parotid acinar cells[1]. Additionally, at concentrations of 10-100 μM, Tyrphostin 8 induces a rapid and substantial increase in the basal O2 consumption of parotid acinar cells[1]. Furthermore, at a concentration of 100 μM, Tyrphostin 8 reduces parotid ATP content by approximately 90%[1]. In another context, Tyrphostin 8 enhances the apical-to-basolateral transport of insulin-transferrin conjugate by promoting transferrin receptor-mediated transcytosis in filter-grown Caco-2 cell monolayers[2]. |
体内活性 | In Streptozotocin-induced diabetic rats, Tyrphostin 8 enhances the glucose-lowering effect of insulin-transferrin[2]. |

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。
