IC50 2 nM 5 nM 4 nM 20 nM 73 nM 1086 nM

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 <10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reacting condition

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.

Application

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.

Background

Staurosporine, an alkaloid produced in Streptomyces staurospores originally as an antifungal agent, is an inhibitor of a broad spectrum of protein kinases, including protein kinase C (PKC), Camp-dependent protein kinase (PKA), phosphorylase kinase, ribosomal protein S6 kinase, epidermal growth factor receptor (EGF-R) kinase and Ca2+/calmodulin-dependent protein kinase II (Ca/CaM PKII). The inhibition potency is strongest for PKC (IC50 = 2.7 nM) but several-fold lower for other protein kinases. Staurosporine exhibits a strong cytotoxicity to some mammalian tumor cell lines, induces cell apoptosis, and arrests fission yeast cell elongation specifically at a stage immediately after cell division.
