Application

Src Inhibitor-1 may be used in Src kinase-mediated cell signaling studies.

Biochem/physiol Actions

Apart from Src kinase, some Src inhibitors also inhibit the activity of Abl kinase, Lck, Csk and Yes proteins and are therefore being explored as viable anti-cancer drug options.
Src Inhibitor-1 is a potent, competitve dual site (both the ATP- and peptide-binding) Src kinase inhibitor. Src Inhibitor-1 is one of the "gold standards" for Src kinase inhibition. It has been shown to use PP1 or PP2 in parallel with Src-I1 to inhbit Src family kinases. Src Inhibitor-1 is a selective, competitive inhibitor of Src family of tyrosine kinases (IC50 = 44 nM and 88 nM for Src and Lck, respectively). Src Inhibitor-1 Inhibits VEGFR2 and c-fms tyrosine kinases at much higher concentrations (IC50 = 0.32 μM and 30 μM, respectively).

We previously reported that several 7-alkoxy-4-phenylamino-3-quinolinecarbonitriles were potent inhibitors of Src kinase activity. We disclose here a new highly efficient and versatile route to these compounds, which are also potent inhibitors of Abl kinase.

Oxidative posttranslational modifications of intracellular proteins can potentially regulate signaling pathways relevant to cartilage destruction in arthritis. In this study, oxidation of cysteine residues to form sulfenic acid (S-sulfenylation) was examined in osteoarthritic (OA) chondrocytes and investigated in normal chondrocytes

Soluble urokinase plasminogen activator receptor (suPAR) is an immune-derived circulating signaling molecule that has been implicated in chronic kidney disease, such as focal segmental glomerulosclerosis (FSGS). Typically, native uPAR (isoform 1) translates to a 3-domain protein capable of binding and
