Four natural epothilone analogues, including two 14-membered epothilones L （1）, L1 （2） and two epoxide opened epothilones A （3） and B （4）, were isolated from the extract of fermentation adsorber resin of Soran...Four natural epothilone analogues, including two 14-membered epothilones L （1）, L1 （2） and two epoxide opened epothilones A （3） and B （4）, were isolated from the extract of fermentation adsorber resin of Sorangium cellulosum strain So0157-2. Their structures were elucidated on the basis of comprehensive NMR and MS data. They are all isolated from the wild type S. cellulosum strain So0157-2 as natural products for the first time.展开更多
