Bruceantin is a chemical compound that was first isolated from the plant Brucea antidysenterica in 1973.^[2] Chemically, it is classified as a secotriterpenoid and a quassinoid.

Bucreantin has attracted interest as a potential antitumor drug because of its antineoplastic activity.^[3] It inhibits the peptidyl transferase elongation reaction, resulting in decreased protein and DNA synthesis.^[3] Bruceantin also has antibiotic, antiamoebic,^[4] and antimalarial activity.^[3]

Phase I and II clinical trials were conducted for the treatment of metastatic breast cancer and malignant melanoma, but tumor regression was not observed and clinical development was terminated.^[5]^[6]
