IN 1946 two crystalline acidic antibiotics (ânudic acids A and Bâ) were isolated from the culture medium of the basidiomycete Tricholoma nudum (Bull.) Fr. and some preliminary work on their respective constitutions was carried out1. It has now been shown that ânudic acid Bâ is identical with âdiatretyne IIâ (7-cyano-trans-hept-2-en-4 : 6-diynoic acid (I)), which is produced by another fungus, Clitocybe diatreta 2, and which has been obtained synthetically (Ashworth, Jones, Mansfield, Schlögl, Thompson and Whiting, unpublished work).
1946年,从担子菌裸盖菇(牛肝菌)的培养基中分离出两种结晶性酸性抗生素(“裸盖酸A和B”),并对其各自的成分进行了初步研究1。现已证实,“裸盖酸B”与“diatretyne II”(7-氰基-反式-庚-2-烯-4:6-二炔酸(I))相同,后者由另一种真菌Clitocybe diatreta 2产生,可通过合成获得(Ashworth、Jones、Mansfield、Schlögl、Thompson和Whiting,未发表)。
