At one time the microbial introduction of a hydroxy group into the tertiary 17a-position of steroids was considered to have potential importance as a stage in the preparation of adreno-corticosteroids. In this connection, 17a-hydroxylation of 21-hydroxyprogesterone (1) was undertaken with Trichothecium roseum 289 and Cephalotheeium roseum 290. [Pg.407]

Further studies have been made concerning the formation of the mycotoxin trichothecin (47) produced by Trichothecium roseum. Earlier reports of H/ C ratios obtained after feeding [2- H2]- or [5- H2]-MVA (together with [2- C]MVA) that had supported the involvement of the co-metabolite crotocin (50) as an... [Pg.192]

Cane et a/.92 have re-examined the biosynthesis of trichodiene (127) by incubation of trans,trans[ -3U2,12,13-14C]farnesyl pyrophosphate (156) [3H/14C atom ratio 2 2] with a cell-free extract of Trichothecium roseum. A crystalline derivative of the trans-diol derived from the endocyclic double bond of labelled trichodiene had a... [Pg.98]

Trichothecin (9.7), the first of the trichothecenes to be isolated, was described as an anti-fungal metabolite of the fungus Trichothecium roseum in 1949. This fungus produces a pink rot on apples and trichothecin has been associated with the bitter taste of infected fruit. The correct structure of trichothecin embodying its 12,13-epoxide was finally established in 1962 as a result of an inter-relationship with trichodermol. The details of this are described in Chapter 5. [Pg.167]

According to the investigations of Fattinger (1950), the fungicidal action of copper is enhanced by cadmium, cobalt, nickel and zinc compounds in Alternaria tenuis and Trichothecium roseum cultures. Zinc sulfate (ZnSO 7HjO) was tried in place of copper sulfate its effect however was inferior to that of the copper compound. Nevertheless, it is still used against rosette disease a physiological disease caused by zinc deficiency. [Pg.272]
