1. Faeriefungin: a new broad-spectrum antibiotic from Streptomyces griseus var. autotrophicus
M G Nair, A R Putnam, S K Mishra, M H Mulks, W H Taft, J E Keller, J R Miller, P P Zhu, J D Meinhart, D G Lynn J Nat Prod. 1989 Jul-Aug;52(4):797-809. doi: 10.1021/np50064a022.
Faeriefungin, a polyol polyene macrolide lactone antibiotic, was isolated from the mycelium of Streptomyces griseus var. autotrophicus, MSU-32058/ATCC 53668, collected from the soil sample of a fairy ring in an old lawn in Lansing, Michigan. Faeriefungin has some properties similar to the previously reported polyene macrolides, mycoticin and flavofungin, but possesses different physiochemical and biological properties. Aspergillus, Fusarium, Microsporum, Trichophyton, and Alternaria spp. were completely inhibited by faeriefungin at 3.2 micrograms/ml, Candida spp. at 5.5 micrograms/ml, and Pythium, Phialophora, Leptosphaeria spp., and some selected Gram-negative penicillin-resistant strains of Neisseria gonorrhoeae at 16.0 micrograms/ml. At a concentration of 100 ppm, it caused 100% mortality of mosquito larvae (Aedes aegypti, Rockefeller strain) and free-living nematodes (Panagrellus redivivus). Unlike the related polyene macrolides, faeriefungin is crystalline and stable with broad-spectrum antimicrobial and insecticidal activity. Preliminary cytotoxicity studies with human erythrocytes and rat liver epithelial cells indicated that faeriefungin and amphotericin B have comparable toxicity. Solution nmr study has indicated that faeriefungin is a mixture of two compounds, faerifungins A [1] and B [2], and that they differ in the attachment of a H or an Me at C-33.
2. [An electron microscopic study of the vegetative mycelia of Actinomyces flavus during flavofungin biosynthesis]
Z I Kulalaeva, V A Poltorak, E I Zaichkin, V S Tiurin, A B Silaev Mikrobiologiia. 1976 Jan-Feb;45(1):133-6.
The vegetative mycelium of a submerged culture of Actinomyces flavus 12 was studied by complex electron microscopy (negative and positive contrasting, cryofractography) in the course of biosynthesis of flavofungin. The antibiotic is accumulated first in the cytoplasm as singular small granules which later grow larger. Accumulation of flavofungin is accompanied with destruction of the cytoplasm, nucleoid and other structures. Secretion of the antibiotic is supposed to be accomplished according to holocrine type.
3. Rare Polyene-polyol Macrolides from Mangrove-derived Streptomyces sp. ZQ4BG
Wenling Wang, Tengfei Song, Weiyun Chai, Lu Chen, Lei Chen, Xiao-Yuan Lian, Zhizhen Zhang Sci Rep. 2017 May 10;7(1):1703. doi: 10.1038/s41598-017-01912-z.
Bioactive natural products from mangrove-derived actinomycetes are important sources for discovery of drug lead compounds. In this study, an extract prepared from culture of an actinomycete Streptomyces sp. ZQ4BG isolated from mangrove soils was found to have activity in inhibiting proliferation of glioma cells. Large culture of this mangrove actinomycete in Gause's liquid medium resulted in isolation of seven novel polyene-polyol macrolides, named as flavofungins III-IX (3-9), together with known flavofungins I (1) and II (2) and spectinabilin (10). Structures of these isolated compounds were elucidated by extensive NMR analyses and HRESIMS data. The stereochemical assignments were achieved by a combination of NOE information, universal NMR database, and chemical reactions including preparation of acetonide derivatives and Mosher esters. Flavofungins IV-VIII (4-8) are rare 32-membered polyene-polyol macrolides with a tetrahydrofuran ring, while flavofungin IX (9) represents the first example of this type of macrolide with a unique oxepane ring. Flavofungins I (1) and II (2) and spectinabilin (10) showed anti-glioma and antifungal activities.
