Abstract

By antimicrobial and cytotoxic-guided fractionation, a bioactive norquinone-methide triterpene, 15α-hydroxypristimerin, was isolated from a South American medicinal plant, Maytenus scutioides. Its structure was determined on the basis of spectroscopic evidence. Successful chemical transformation of pristimerin to netzahualcoyene indicates that the 15-hydroxy compounds seems to be a possible precursor of 14(15)-ene-quinone-methide-triterpenoids in the biogenetic pathway.
