Oxygenated terpenes from Indo-Pacific nudibranchs: Scalarane sesterterpenes from Glossodoris hikuerensis and 12-acetoxy dendrillolide a from Goniobranchus albonares

Abstract

Two new scalarane sesterterpenes (1, 2) were characterized from an organic extract of a single specimen of the nudibranch Glossodoris hikuerensis collected from Bali. 12-Acetoxy dendrillolide A (10) was identified from specimens of Goniobranchus albonares, while dendrillolide A (11) was isolated both from G. albonares and its sponge diet. The structures and relative configuration of the new metabolites have been elucidated by analysis of their spectroscopic data.
