Background

Staurosporine (CAS 62996-74-1) is an alkaloid compound originally isolated from the bacterium Streptomyces staurospores and functions as a broad-spectrum inhibitor of serine/threonine protein kinases. It potently inhibits multiple kinases, including protein kinase C (PKC), protein kinase A (PKA), epidermal growth factor receptor kinase (EGF-R kinase), calmodulin-dependent protein kinase II (CaMKII), phosphorylase kinase, and ribosomal protein S6 kinase. Its activity against PKC exhibits an IC50 value of approximately 2.7 nM. In biomedical research, staurosporine is commonly employed to induce apoptosis in mammalian cancer cell lines and to investigate the roles and signaling pathways of protein kinases.

Protocol

Cell experiment:

Cell lines

A31 cell lines, CHO-KDR cell lines, Mo-7e cell lines and A431 cell lines.

Preparation method

The solubility of this compound in DMSO is

Reaction Conditions

24 h; IC50=0.08 mM (A31 cell lines), IC50=0.30 mM (Mo-7e cell lines), IC50=1.0 mM (CHO-KDR cell lines).

Applications

Staurosporine inhibited the ligand-induced autophosphorylation of the receptors for platelet-derived growth factor (PDGF) (IC50=0.08 mM) in A31 cell lines, stem cell factor (c-Kit, IC50=0.30 mM) in Mo-7e cell lines, and for VEGF (KDR, IC50=1.0 mM) in CHO-KDR cell lines, but did not affect the ligand-induced autophosphorylation of the receptors for insulin, IGF-I, or epidermal growth factor (EGF) in A431 cell lines.

Animal experiment:

Animal models

Athymic nude mice

Dosage form

75 mg/kg/day; oral taken.

Applications

The treatment with Staurosporine (75 mg/kg/day p.o.) completely inhibits the angiogenic response to VEGF, but not to bFGF. Thus, Staurosporine may suppress tumor growth by inhibiting tumor angiogenesis (via its effects on the VEGF-R tyrosine kinases) in addition to directly inhibiting tumor cell proliferation (via its effects on PKCs). This anti-angiogenic action may contribute to the antimetastatic and broad antitumor activity displayed by Staurosporine, as well as the synergy with cytotoxic agents.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
