In the present work, the oxoaporphine alkaloid dicentrinone was isolated, for the first time, from leaves of Ocotea puberula (Lauraceae). This alkaloid exhibited antiparasitic activity against trypomastigote forms of Trypanosoma cruzi (IC50 of 16.4 ± 1.7 μM), similar to the positive

Prijava / prijava
In a continuation of our search for potential tumor inhibitors from plants, we found that a crude extract from Ocotea leucoxylon showed selective activity typical of inhibitors of the enzyme topoisomerase I in a yeast assay for DNA-damaging agents. Using a bioassay-directed fractionation approach,
