inhibition of PGE2 formation in human blood by four bicyclico [3.2.1] octane neolignans isolated from
Aniba firmula
bark, two with unusual structural pattern
Abstract:The phytochemical investigation of the stem bark crude extract of Aniba firmula (Lauraceae) led to the isolation of undescribed bicyclic [3.2.1] octane neolignans, 1 and 2, characterized by unusual bicyclic patterns and two other known bicyclic neolignans 3 and 4. Anti-inflammatory bicyclic [3.2.1] octane neolignans metabolites were previously reported in the literature, and the A. firmula stands out in the Lauraceae family as a source of potentially bioactive compounds. Thus, herein the anti-inflammatory pote… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
