This investigation aimed to evaluate the in vitro effect of harmaline and piperine against T. gondii tachyzoites in infected Vero cell cultures. After 24 hours of host cell infection, the cultures were treated with harmaline or piperine (0.49 to 15.63 µg/mL). Negative and positive controls were RPMI/DMSO (0.1%) and sulfadiazine (200 µg/mL).

According to an intracellular parasite proportion scale, it was observed that the Vero cells with low or moderate parasitic proliferation were more prevalent after the alkaloid treatment.
