Biochem/physiol Actions

K-252a is also a specific inhibitor of Trk (tyrosine kinase) receptors and selectively blocks the effect of nerve growth factor. At lower concentrations, K-252a acts as a neuroprotective compound prompting survival of primary neuronal cultures. K-252a induces cell cycle arrest and apoptosis by inhibiting both Cdc2 and Cdc25c. K-252a improves psoriasis in a SCID mouse-human skin model and also suppresses referred mechanical hypersensitivity and neuropeptide up-regulation associated with acute pancreatitis.

The organic molecule K-252a promoted cell survival, neurite outgrowth, and increased choline acetyltransferase (ChAT) activity in rat embryonic striatal and basal forebrain cultures in a concentration-dependent manner. A two- to threefold increase in survival was observed at 75 nM K-252a

The indole carbazole K252a has been shown in previous studies to inhibit the platelet-derived growth factor signal transduction pathway in gliomas. Because K252a has nonspecific effects on protein kinase function, we studied its effect on cyclin-dependent kinases (CDK) and cell
