  Biotransformation of Bioactive Isocaryolanes by Botrytis cinerea

  摘要：

  The metabolism of the fungistatic agent (8R,9R)-8-methoxyisocaryolan-9-ol (4) by the fungus Botrytis cinerea has been investigated. Biotransformation of compound 4 yielded compounds 5 and 6-9. No dihydrobotrydial is observed after 4 days of incubation of compound 4. Separate biotransformation of (8R,9R)-isocaryolane-8,9-diol (5) yielded compounds 7-11. The evaluation of the fungistatic activity against B. cinerea of compounds 4, 5, and 6 is reported. (4R,8R,9R)-8-Methoxyisocaryolane-9,15-diol (6), a major metabolite of (8R,9R)-8-methoxyisocaryolan-9-ol (4), shows a much reduced biological activity when compared with the parent compound. Isocaryolane derivatives 6-11 are described for the first time.

  Under modified Mitsunobu reaction conditions, a novel skeleton rearrangement of terpenes has been obtained. The reactivity of 8, 9-dioxygenated isocaryolane derivatives has been investigated. When either (8R,9R)-8-methoxyisocaryolane-9-ol (7) or (8R, 9R)-isocaryolane-8,9-diol (10) are treated under acidic conditions, isocaryolan-9-one (9) and the rearrangement compound (1S,2S,5R,8S)-1, 4,4-trimethyltricyclo[6

  Research has been conducted on the biotransformation Of (8S,9R)-isocaryolan-9-ol (4a) and (1S,2S,5R,8S)-8-methylene-1,4,4-trimethyltricyclo [6.2.1.0(2'5)] uridecan-12-ol (5a) by the fungal phytopathogen Botrytis cinerea. The biotransformation of compound 4a yielded compounds 6-9, while the biotransformation of compound 5a yielded compounds 10-13. The activity of compounds 4a and 5a against B. cinerea has been evaluated. (8R,9R)- Isocaryolane-8,9-diol (6), a major metabolite of compound 4a, shows activity compared to its parent compound 4a, which is inactive. The effect of isocaryolanes 3,4a, and 5a, together with. their biotransformation products 6-8, 10, and 14-17, on the germination and radicle and shoot growth of Lactuca sativa (lettuce) has also been determined. Compounds 7-13 are, described for the first time.
