Description
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.

EGFR:560 μM (IC50), Calcineurin phosphatase:21 μM (IC50)
In vitro
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].
In vivo
In Streptozotocin-induced diabetic rats, Tyrphostin 8 enhances the glucose-lowering effect of insulin-transferrin[2].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
