title: A new inhibitor of protein kinase C, RK-1409 (7-oxostaurosporine). II. Fermentation, isolation, physico-chemical properties and structure.
abstract: RK-1409, a new inhibitor of protein kinase C, was isolated from the culture broth of Streptomyces platensis subsp. malvinus RK-1409. The structure was elucidated as 7-oxostaurosporine on the basis of spectroscopic analyses and oxidation of staurosporine.
