Product Description
Staurosporine is a broad spectrum protein kinase inhibitor. Enzymes inhibited include protein kinase C, p60v-src tyrosine protein kinase, protein kinase A, and CaM kinase II (IC50 values are 3nM, 6 nM, 7 nM and 20 nM, respectively). Staurosporine reduces nuclear myosin heavy chain 9 phosphorylation which inhibits gastric cancer cell progression in transgenic mouse models. Staurosporine inhibits cell viability and promotes apoptosis in oral and pancreatic cancer cells. Staurosporine also enhances efficiency of lentiviral transduction of human hematopoietic stem and progenitor cells by 2-fold, induces dopaminergic axonal outgrowth in vitro and triggers mitophagy. Staurosporine has high affinity (Kd = 100 nM) for the yjdF aptamer. The riboswitch function of yjdF motif RNAs is activated by Staurosporine and leads to robust reporter gene expressions in B. subtilis.Staurosporine synthesized to Ancillary Material Grade is also available.
Scientific Data Images for Staurosporine
Reduced viability of differentiated cardiomyocytes exposed to cardiotoxic small molecules.
The viability of differentiated cardiomyocytes was assessed using a Resazurin metabolism assay. A) Untreated cells metabolize Resazurin (Catalog # AR002) to produce resorufin, a fluorescent molecule that can be measured using a fluorometric plate reader. Resorufin fluorescence accumulated in untreated cardiomyocytes. Cells treated with the cardiotoxic small molecules Staurosporine (blue; Catalog # 1285), a non-selective protein kinase inhibitor, or Doxazosin (tan; Catalog # 2964), an alpha1 antagonist, did not metabolize Resazurin, as shown by lack of fluorescence accumulation, indicating a loss of viability upon treatment. B) Cell morphology of untreated, Staurosporine-treated, and Doxazosin-treated cardiomyocytes was assessed by brightfield microscopy.Product Specifications
