| Description | Tyrphostin 8 is a tyrosine kinase, with an IC50 of 560 μM for EGFR kinase. Tyrphostin 8 is also a GTPase inhibitor. Tyrphostin 8 can inhibit the protein serine/threonine phosphatase calcineurin (IC50=21 μM)[1][2][3]. |

| In Vitro | Tyrphostin 8 (10-100 μM; pretreated for 20 min) blocks the Carbachol-initiated PKCδ tyrosine phosphorylation and ERK1/2 activation in parotid acinar cells[1]. Tyrphostin 8 (10-100 μM) produces a rapid and large increase in the basal O2 consumption of parotid acinar[1]. Tyrphostin 8 (10-100 μM) reduces the parotid ATP content by ∼90% at the concentration of 100 μM[1]. Tyrphostin 8 increases apical-to-basolateral transport of insulin-transferrin conjugate by enhancing transferrin receptor-mediated transcytosis in filter-grown Caco-2 cell monolayer[2]. Western Blot Analysis[1] Cell Line: Parotid acinar cells Concentration: 10, 100 μM Incubation Time: Pretreated for 20 min Result: Reduced the increase in tyrosine phosphorylation of PKCδ initiated by carbachol. Reduced the activation of ERK1/2 by carbachol. | 
| In Vivo | Tyrphostin 8 improves the glucose-lowering effect of Insulin-transferrin in Streptozotocin-induced diabetic rats[2]. |
