Abstract: | Pladienolide B is a 12-membered macrolide isolated from Streptomyces platensis Mer-11107. It showed potent in vitro and in vivo antitumor activities and is a potential lead for novel antitumor agents. The absolute configurations at ten chiral centers were determined on the basis of spectral data of pladienolide B and its chemical transformation products. |
