Tyrphostin 8

SKU: orb1694982

Description

Tyrphostin 8 is a GTPase and EGFR kinase inhibitor that also potently inhibits calmodulin-dependent phosphatases. It enhances transferrin receptor-mediated transcytosis in Caco-2 cell models and has been shown to augment the oral hypoglycemic effect of insulin-transferrin conjugates in research studies.

Bioactivity

• Target IC50:
  Calcineurin phosphatase:21 μM (IC50)|EGFR:560 μM (IC50)
• In Vivo:
  In Streptozotocin-induced diabetic rats, Tyrphostin 8 enhances the glucose-lowering effect of insulin-transferrin.
• 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. Additionally, at concentrations of 10-100 μM, Tyrphostin 8 induces a rapid and substantial increase in the basal O2 consumption of parotid acinar cells. Furthermore, at a concentration of 100 μM, Tyrphostin 8 reduces parotid ATP content by approximately 90%. 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.
