Ten acetogenins, one of them new, were isolated from leaves and twigs of a Bolivian collection of Annona montana. The new compound that we named tucupentol (1) is a mono-tetrahydrofuran-pentahydroxy-acetogenin. The inhibitory potency of tucupentol (1) on the mitochondrial complex I was evaluated, and this activity was compared with that of the known acetogenins, annonacin-A, cis-annonacin-10-one, aromin, and gigantetronenin, also isolated from this plant material. The mentioned acetogenins acted as selective inhibitors of mitochondrial complex I in the 0.8-5.4-nM range.
