Alternative Name: SF 2370

Chemical Name: (9S,10R,12R)-2,3,9,10,11,12-Hexahydro-10-hydroxy-9-methyl-1-oxo-9,12-epoxy-1H-diindolo[1,2,3-fg:3',2',1'-kl]pyrrolo[3,4-i][1,6]benzodiazocine-10-carboxylic acid methyl ester

Biological Activity

Non-selective protein kinase inhibitor; analog of staurosporine (Cat.No. 1285). Inhibits PKC (IC50 = 32.9 nM), Ca2+/calmodulin-stimulated phosphodiesterases (IC50 = 1.3 - 2.9 μM), MLCK (Ki = 20 nM) and receptor tyrosine kinases. Inhibits the oncogenic properties of MET; prevents autophosphorylation and activation of downstream effectors (MAPK, Akt).

Technical Data

Soluble to 25 mM in DMSO
>98 %
Desiccate at -20°C
