Labdane diterpenes from the marine pulmonate gastropod Trimusculus peruvianus

Abstract

The marine gastropod mollusk *Trimusculus peruvianus collected on the coast of Central Chile yielded four new labdane metabolites. The structural elucidation of all compounds was accomplished by spectral analysis. One diterpenoid showed modest antimicrobial activity.
