Use | Tyrphostin 23 can be used as a tyrosine kinase inhibitor for studying rat ghrelin-induced MAPK stimulation in GH3 cells. Tyrphostin 23 has also been used to analyze its effects on secretoneurin (SN)-induced chemotaxis of neutrophils. |
In vitro study | AG 18 inhibited EGFR and IR, and K I was 11 μm and 12 mM, respectively. AG 18 acted on A431 cells to inhibit EGFR autophosphorylation induced by EGF, and the IC50 was 15 μm. AG 18 (10 μm) inhibited the proliferation of GH3 cells induced by EGF. AG 18(10 μm) now inhibits cell proliferation induced by 10 nM and 1 μm Ghrelin. AG 18(10 μm) inhibited Ghrelin-stimulated increase in ERK1/2 phosphorylation in GH3 cells. AG18 acts on primary cultured astrocytes, inhibits volume-sensitive [AG 18 (300μm) acts on A549 epithelial cells, and inhibits TPA-induced stimulation of ICAM-1 expression in a dose-dependent manner. AG 18(300 μm) also inhibited TPA-stimulated NF-kappaB DNA-protein binding and ICAM-1 promoter activity in A549 epithelial cells. AG 18(100 μm) inhibits TNF-alpha-and TPA-stimulated IKK activity in A549 epithelial cells. AG 18(10 μm) acts on the carotid artery, reducing the potency of 5-HT by a factor of 4 and reducing the maximum contraction of 5-HT. AG 18(10 μm) transferred 2-fold KCl-induced contraction and produced maximal significant inhibition. |
