Application

Tyrphostin 47 has been used in LOPAC screening assays to identify human tissue transglutaminase (TGM2) inhibitors. Tyrphostin 47 has also been used to study its effects on hyperpolarization-activated cation current in porcine pacemaker cells.

Biochem/physiol Actions

Tyrphostin 23 is a small molecule inhibitor of epidermal growth factor (EGF) receptor kinase function. This molecule associates with the substrate subsite of the protein tyrosine kinase (PTK) domain,.
EGFR tyrosine kinase inhibitor.

Preparation Note

Tyrphostin 47 is is soluble in DMSO (50 mg/ml) and yields a clear, orange solution. The product is also soluble in ethanol (40 mM).

The present study reported proof-of-principle for a kinase assay approach that can detect specific peptide phosphorylation events. The method involves attachment of peptides onto commercial aminosilane and polycarbodiimide-coated glass slides, using a newly developed DNattach linker system that consists of

Bradykinin (1 microM) and histamine (100 microM) evoked an initial transient increase and a subsequent sustained increase in intracellular Ca(2+) concentration ([Ca(2+)](i)) in fura-2-loaded human gingival fibroblasts, which may be attributed to Ca(2+) release from intracellular stores and Ca(2+) entry
