[Annomonysvin: a new cytotoxic gamma-lactone-monotetrahydrofuranyl acetogenin from Annona montana]. / Annomontacine: une nouvelle acétogénine gamma-lactone-monotetrahydrofurannique cytotoxique de l'Annona montana.

The structure of annomontacin [I], a novel monotetrayhydrofuran fatty acid gamma-lactone (acetogenin) isolated from the seeds of Amnona montana, was determined by spectral analysis. The cytotoxicities in vitro of annomontacin [I], annonacinone [2], and annonacin were measured against murine leukemia L1210, human breast adenocarcinoma MDA-MB231, and human breast carcinoma MCF7 cell lines and compared with adriamycin.
