| General description: | Chemical structure: indol derivative |
| General description: | Staurosporine is an alkaloid that is obtained from Streptomyces sp. It possesses a wide range of activities such as protein kinase C inhibitor, inhibition of tumor cell proliferation, and blockage of cell cycle progression in various cells. Staurosporine is a well-known inducer of apoptosis in various cell lines. The mechanisms of staurosporine-induced apoptosis vary among different cell lines that include, mitochondrial apoptotic pathway, Bcl-2 overexpression, and caspase-independent mechanisms. It partially reverses multi-drug resistance (MDR), sensitizing cells with MDR phenotype to cytotoxic agents. Staurosporine inhibits p-glycoprotein (Pgp) phosphorylation. However, the functional significance of Pgp phosphorylation is ill-defined. |
