, p. 807 - 809 (2007/10/02)
Incubation of a series of 6-oxygenated ent-kaur-16-enes with Gibberella fujikuroi affords the seco ring B derivative, fujenal, and some other metabolites.
THE MICROBIOLOGICAL TRANSFORMATION OF SOME ENT-KAUR-6,16-DIENES BY GIBBERELLA FUJIKUROI
Fraga, Braulio M.,Gonzalez, Antonio G.,Gonzalez, Pedro,Hanson, James R.,Hernandez, Melchor G.
, p. 691 - 694 (2007/10/02)
The preparation of ent-kaur-6,16-diene and ent-18-hydroxykaur-6,16-diene from epicandicandiol and of ent-3β,18-dihydroxykaur-6,16-diene from foliol is described.On incubation with Gibberella fujikuroi ent-kaur-6,16-diene gave 7-hydroxykaurenolide and 18-hydroxykaur-6,16-diene afforded 7,18-dihydroxykaurenolide, whilst ent-6α,7α-epoxy-3β,18-dihydroxykaur-16-ene was obtained from ent-3β,18-dihydroxykaur-6,16-diene.The possible biosynthetic significance of the 6,7-epoxidation in kaurenolide is noted. -- Key Word Index - Gibberella fujikuroi; ent-kaur-6,16-dienes; ent-6α,7α-epoxy-3β,18-dihydroxykaur-16-ene; kaurenolide biosynthesis.
THE INHIBITION OF GIBBERELLIN PLANT HORMONE BIOSYNTHESIS BY ENT-6-OXO-5&β(H)-7-NORGIBBERELL-16-ENES
Hanson, James R.,Parry, Keith P.,Willis, Christine L.
, p. 1955 - 1958 (2007/10/02)
Ent-19-hydroxy-6-oxo-5β(H)-7-norgibberell-16-ene and the corresponding 19-carboxylic acid are shown to be inhibitors of gibberellin biosynthesis in the fungus, Gibberella fujikuroi, at stages involved in the oxidative modification of ring B of the kaurenoid precursors.Key Word Index - Gibberella fujikuroi; Hypocreales; biosynthesis; gibberellic acid; plant growth regulator.
THE MICROBIOLOGICAL TRANSFORMATION OF SOME ENT-KAUR-16-ENE 7-, 15- AND 18-ALCOHOLS BY GIBBERELLA FUJIKUROI
Fraga, Braulio M.,Hanson, James R.,Hernandez, Melchior G.,Sarah, Fahmi Y.
, p. 1087 - 1092 (2007/10/02)
The effect of the 7-, 15- and 18-hydroxyl groups on the microbiological transformation of some diterpenoids by Gibberella fijikuroi has been studied.An 18-substituent appears to exert an inhibitory effect on transformation involving reaction at the 6β-position. - Key Word Index: Gibberella fujikuroi; candol A; candol B; sideridiol; 7,18-dihydroxykaurenolide.
