Reference Reading
1. Microbial conversion of steffimycin and steffimycin B to 10-dihydrosteffimycin and 10-dihydrosteffimycin B
P F Wiley, D W Elrod, J M Slavicek, V P Marshall J Antibiot (Tokyo). 1980 Aug;33(8):819-23. doi: 10.7164/antibiotics.33.819.
It has been shown that steffimycin (1) and steffmycin B (2) are reduced at the C-10 carbonyl by Actinoplanes utahensis, UC-5885 and Chaetomium sp., UC-4634, respectively. Using cell-free extracts of the latter organism, the optimum conversion time, pH, and enzyme concentration have been determined for the conversion of 2 to 4. The biochemical conversion of 2 has been found to be TPNH linked.
2. Steffimycin E, a new anti-mycobacterial agent against Mycobacterium avium complex, produced by Streptomyces sp. OPMA02852
Nobuhiro Koyama, Satoru Shigeno, Akihiko Kanamoto, Hiroshi Tomoda J Antibiot (Tokyo). 2020 Aug;73(8):581-584. doi: 10.1038/s41429-020-0290-9. Epub 2020 Mar 4.
The marine actinomycete strain OPMA02852, identified as the genus Streptomyces, was found to produce anti-mycobacterial compounds against Mycobacterium avium complex (MAC). One new compound, designated as steffimycin E (1), was isolated together with three known steffimycins (steffimycin (2), 10-dihydrosteffimycin (3), and 8-demethoxysteffimycin (4)) from the culture broth of this producing microorganism by solvent extraction, ODS column chromatography, and preparative HPLC. Compound 1 has a tetracyclic quinone structure with a sugar moiety. Compound 1 exhibited anti-mycobacterial activity against M. intracellulare, M. bovis BCG, and M. smegmatis.
