UCN-01 and UCN-02, new selective inhibitors of protein kinase C. I. Screening, producing organism and fermentation.
TLDR
In the course of continued screening program for new selective inhibitors of protein kinase C (PKC), fermentation broths from over 5,000 soil isolates were screened for their inhibitory activity of PKC and the pH control of fermentation resulted in an increase of the production of UCN-01 andUCN-02.
