title: Cytotoxic mono-tetrahydrofuran ring acetogenins from leaves of Annona montana.
abstract: Further studies on leaves of Annona montana led to isolation of one iso-acetogenin, montanacin G, three pairs of acetogenins, montanacin H-J and 34-epi-montanacin H-J, together with four known acetogenins, gigantetrocins A and B, annonacin and cis-annonacin. Montanacin G belongs to the iso-acetogenin group with a terminal 2,4-trans-ketolactone unit. Montanacin H-J and 34-epi-montanacin H-J contain the rare gamma-hydroxy-gamma-methyl-gamma-lactone moiety. The cytotoxic activities of these compounds, together with previously reported acetogenins, montanacins B and C, were examined against Meth-A and LLC tumor cell lines in vitro.
