PROCESS FOR PRODUCING MACROLIDE COMPOUND

摘要

It is intended to provide a novel process for producing a 12-membered macrolide compound 11107D having an antitumor activity via biological conversion. The 12-membered macrolide compound 11107B represented by the formula (I), which is a starting substance, is incubated in the presence of a strain capable of converting it into the compound 11107D represented by the formula (II) and belonging to the genus Mortierella or Streptomyces or the family of Micromonosporaceae(for example, Streptomyces sp. AB-1704 strain (FERM BP-8551)) or a cultured cell preparation thereof together with oxygen and then the target compound 11107D is harvested from the incubation medium.
