| In vitro(体外研究) | Staurosporine, a microbial alkaloid, significantly inhibits protein kinase C from rat brain with IC50 of 2.7 nM. Staurosporine displays strong inhibitory effect against HeLa S3 cells with IC50 of 4 nM. Staurosporine also inhibits a variety of other protein kinases, including PKA, PKG, phosphorylase kinase, S6 kinase, Myosin light chain kinase (MLCK), CAM PKII, cdc2, v-Src, Lyn, c-Fgr, and Syk with IC50 of 15 nM, 18 nM, 3 nM, 5 nM, 21 nM, 20 nM, 9 nM, 6 nM, 20 nM, 2 nM, and 16 nM, respectively. Staurosporine (1 μM) induces >90% apoptosis in PC12 cells. Consistently, Staurosporine treatment induces a rapid and prolonged elevation of intracellular free calcium levels i, accumulation of mitochondrial reactive oxygen species (ROS), and subsequent mitochondrial dysfunction. The apoptosis of MCF7 cells induced by Staurosporine can be enhanced by the expression of functional caspase-3 via caspase-8 activation and Bid cleavage. Staurosporine treatment at 1 μM only partially inhibits IL-3-stimulated Bcl2 phosphorylation but completely blocks PKC-mediated Bcl2 phosphorylation. Staurosporine induces apoptosis of human foreskin fibroblasts AG-1518, depending on the lysosomal cathepsins D mediated cytochrome c release and caspase activation. In addition to activating the classical mitochondrial apoptosis pathway, Staurosporine triggers a novel intrinsic apoptosis pathway, relying on the activation of caspase-9 in the absence of Apaf-1. |
| In vivo(体内研究) | In the gerbil and rat ischemia models, Staurosporine pretreatment (0.1-10 ng) before ischemia prevents neuronal damage in a dose-dependent manner, suggesting the involvement of PKC in CAl pyramidal cell death after ischemia. |
