Abstract
Cultivation of Streptomyces chartreusis NRRL 11407 in the presence of antibiotic A23187 methyl ester produces 16-hydroxy A23187 methyl ester, 16-hydroxy-N-demethyl A23187 methyl ester, and N-demethyl A23187 methyl ester. Hydrolysis of the products affords the corresponding free acids which form dimeric complexes with divalent cations.
