dc.description.abstractThe in vitro anti-proliferative effects are described of several atisine-type diterpenoid alkaloids against the protozoan parasite Leishmania infantum, which causes human visceral leishmaniasis and canine leishmaniasis in the Mediterranean basin, as well as human cutaneous leishmaniasis throughout the Mediterranean region. From a total of 43 compounds tested, including C19- and C20-diterpene alkaloids from several chemical classes, only 15,22-O-diacetyl-19-oxo-dihydroatisine, azitine and isoazitine were highly active against cultures of the parasite (promastigote form) with IC50 values within the range of the reference drug pentamidine-isothionate (7.39–12.80 mg/L for the test compounds, 11.32 mg/L for the positive control). These compounds were not toxic to the host cell. When treated with a dosage of 5 μg/mL of the active compounds (half of their IC50), the promastigote forms lost 80% of their infection capacity and the multiplication of extracellular forms of L. infantum was severely affected. The study showed that atisine-type C20-diterpenoid alkaloids exhibited promising anti-leishmanial properties with strong molecular selectivity. These might have implications for other intracellular pathogens- or phylogenetically related parasites, such as Trypanosoma spp.-
