ChEBI: Bruceine A is a quassinoid.

Biological Activity

ic50: 7.7 nm against the parasitescanine babesiosis is a tick-borne disease caused by the intraerythrocytic apicomplexan parasites, babesia gibsoni and b. canis. clinical signs of b. gibsoni infection are anemia, fever, thrombocytopenia, splenomegaly, lymphadenopathy, and lethargy. bruceine a, a natural quassinoid compound extracted from the brucea javanica (l.) merr. dried fruits, was reported to have antibabesial activity.

Physiological effects

Bruisein A has an effect of treating malignant tumor, antimalarial and anti-inflammatory.

in vitro

bruceine a inhibited the in-vitro babesia gibsoni growth in canine erythrocytes at lower concentration compared with the antibabesial drug diminazene aceturate and killed the parasites within 24 hr at a concentration of 25 nm [1].

in vivo

oral administration of bruceine a at a dosage of 6.4 mg/kg/day for 5 days resulted in no clinical findings in a dog. an untreated dog developed typical acute babesiosis symptoms including high fever, severe anemia, and complete loss of appetite and movement. however, the two bruceine a-treated dogs maintained their healthy conditions throughout the experimental period of 4 weeks [1].
