Coprinus quadrifidus

Eine wesentlich polarere Verbindung, die Jones und Stephenson (155) aus der Kulturlosung von Coprinus quadrifidus isolieren konnten,... 

The quadrifidins were detected as antibiotic compounds in cultures of the basidiomycete, Coprinus quadrifidus (Doery et al., 1951). The spectra of two of these compounds, published in the original paper, were characteristic of polyacetylenes. Because of this, the organism was later investigated again, and structures of four poly acetylenes isolated from it were reported (Jones and Stephenson, 1959). 

Direct proof of the biological validity of this type of decarboxylation was afforded by enzymatic decarboxylation of an a-acetylenic acid. Gardner et al, (1961) incubated the ten-carbon a-acetylenic acid (XXXVIII) with a cell free extract of Coprinus quadrifidus mycelium and isolated from the extract a compound (XXXIX) containing one less carbon and a free ethynyl group.
