Strobilurins: Evolution of a New Class of Active Substances

The strobilurins--new antifungal antibiotics from the basidiomycete Strobilurus tenacellus.

The strobilurins are two antifungal antibiotics which were isolated from the mycelium of Strobilurus tenacellus strain No. 21602. The strobilurins A and B are highly active against yeasts and filamentous fungi. In vitro antitumor activity was tested using cells of the ascitic form of EHRLICH carcinoma. The strobilurins strongly inhibited the incorporation of radioactive leucine, uridine, and th...

Agrochemical Discovery: Finding New Fungicides From Natural Products

The continuing development of fungicide resistance in plant and human pathogens necessitates the discovery and development of new fungicides. Discovery and evaluation of natural product fungicides is largely dependent upon the availability of miniaturized antifungal bioassays. Essentials for natural product bioassays include, sensitivity to microgram quantities, selectivity to determine optimum...

Strobilurins F, G and H, three new antifungal metabolites from Bolinea lutea. II. Structure determination.

To date six antifungal antibiotics of the strobilurin-type are known (Scheme 1): Strobilurin A (1)1>2) which is identical with mucidin3), strobilurin B (2)ia\ strobilurin C (3)4), methoxymucidin (4)5), hydroxystrobilurin D6) and strobilurin E7). They contain an unsaturated side chain with a terminal (£)-/?-methoxyaerylate moiety and differ usually in their aromatic substitution. In the precedin...
