Description

General description

Chemical structure: indol derivative

Staurosporinefrom Streptomyces sp. is an alkaloid that induces apoptosis in a rangeof cell lines. It facilitates the inhibition of tumor cell proliferation, PKCinhibition, and blockage of cell cycle progression in various cells.[1] Themechanisms followed by staurosporine-induced apoptosis differ among differentcell lines that include, mitochondrial apoptotic pathway, Bcl-2 overexpession,and caspase-independent mechanisms.[2] It partially reverses multi-drug resistance (MDR), sensitizing cellswith MDR phenotype to cytotoxic agents. Staurosporine inhibits p-glycoprotein(Pgp) phosphorylation. However, the functional significance of Pgpphosphorylation is ill-defined.

Application

Staurosporine from Streptomyces sp. was used to induce cell death in human mesenchymal stem cells[3] and to induce cell death by PKC inhibition in hamster lung fibroblast line CCL-39.[4]

Biochem/physiol Actions

Potent inhibitor of phospholipid/calcium-dependent protein kinase. Inhibits the upregulation of VEGF expression in tumor cells.

Staurosporine from Streptomyces sp. yields clear, colorless to faint yellow solution in methanol at 2 mg/ml.
