Neoiriepentaol and nangenyne, halogenated diterpenoid and C15-acetogenin from red alga Laurencia nangii Masuda collected in Borneo [2018]
The red algal genus Laurencia is a prolific producer of halogenated secondary metabolites. A new tricyclic dibrominated diterpenoid, neoiriepentaol (1) and chlorinated C₁₅-acetogenin, nangenyne (2), along with two known terpenoids, neoirietetraol (3) and dactyloxene A (4), were isolated from methano...
