Abstract
In a continuous study on the Indonesian marine sponges, we found a Hyrtios sponge during our expedition in Lhok Mata Ie, an isolated place around Aceh Besar, Indonesia in 2017. The bioassay-guided separation with several steps of chromatography was applied to give pure material. Moreover, the spectroscopic analysis revealed the presence of puupehenone (1), a unique class of merosesquiterpene together with its analogs (2-3). Their structures and bioactivity against multidrug-resistant Escherichia coli (MDR E. coli) together with several cell lines are described here.
