Microbial and chemical transformation studies of the marine sesquiterpene phenols (S)-(+)-curcuphenol (1) and (S)-(+)-curcudiol (2), isolated from the Jamaican sponge Didiscus oxeata, were accomplished. Preparative-scale fermentation of 1 with Kluyveromyces marxianus var. lactis (ATCC 2628) has resulted in the isolation of six new metabolites: (S)-(+)-15-hydroxycurcuphenol (3), (S)-(+)-12-hydroxycurcuphenol
从牙买加海绵Didiscus oxeata分离出的海洋倍半萜烯酚(S)-(+)-姜酚(1)和(S)-(+)-姜二醇(2)的微生物和化学转化研究完成。马克斯克鲁维酵母1的制备规模发酵。乳酸(ATCC 2628)导致分离出六种新代谢产物:(S)-(+)-15-羟基姜酚(3),(S)-(+)-12-羟基姜酚(4),(S)-( +)-12,15-二羟基姜酚(5),(S)-(+)-15-羟基姜酚-12-al(6),(S)-(+)-12-羧基-10,11-二氢姜酚(7) )和(S)-(+)-12-羟基-10,11-二氢姜酚(8)。将1与小曲霉(NRRL 315)孵育14天,得到新化合物(S)-(+)-10beta-hydroxycurcudiol(9),(S)-(+)-curcudiol-10-one(10)和(S)-(+)-4- [1-(2-羟基-4-甲基)苯基)]戊酸(11)。温育6天和8天时,阿勒根霉(ATCC
