| isolation, structure elucidation and biological activity of metabolites from sch-642305-producing endophytic fungus phomopsis sp. cmu-lma. | eight polyketide compounds were isolated from the cultivation broth of phomopsis sp. cmu-lma. we have recently described lma-p1, a bicyclic 10-membered macrolide, obtained as a bioconversion derivative of sch-642305, the major compound isolated in this study. benquinol is the ethyl ester derivative of the 13-dihydroxytetradeca-2,4,8-trienoic acid produced by valsa ambiens. this compound is concomitantly produced with the 6,13-dihydroxytetradeca-2,4,8-trienoic acid (dhtta) previously isolated fro ... | 2011 | 21924749 |
