Puupehenol
WebDec 27, 2016 · A study of the chemical constituents from the Australian Sponge Hyrtios digitatus has provided a perspective on the connection between the chemistry and biology of the puupehenones, a unique and unusual class of merosesquiterpenes. In this study, a new tetracyclic merosesquiterpene, 19-methoxy-9,15-ene-puupehenol (1) was isolated … WebOn the basis of these observations the sample was selected for further investigation. The CH3OH extract of the sponge was fractionated by RP-HPLC to yield two meroterpenoids, the new metabolite puupehenol (1) and the known compound puupehenone (2).20 The molecular formula of 1 was determined to be C21H30O4 by accurate mass measurement.
