In a study published in the “Journal of Medicinal Chemistry”, fourteen structurally diverse Annonaceous acetogenins, found in Guyabano extract were identified and tested for their ability to inhibit the growth of adriamycin resistant human mammary adenocarcinoma cells. This cell line is known to be multidrug resistant cancer cells. Some of the acetogenins from the guyabano extract were found to be more potent than adriamycin and thus may have chemotherapeutic potential, especially with regard to multidrug resistant tumors”.
