Bruceantin
methyl (1R,2S,3R,6R,8R,13S,14R,15R,16S,17S)-3-[(E)-3,4-dimethylpent-2-enoyl]oxy-10,15,16-trihydroxy-9,13-dimethyl-4,11-dioxo-5,18-dioxapentacyclo[12.5.0.01,6.02,17.08,13]nonadec-9-ene-17-carboxylate
Bruceantin is a triterpenoid. Bruceantin is a natural product found in Brucea javanica and Brucea antidysenterica with data available. Bruceantin is a triterpene quassinoid antineoplastic antibiotic isolated from the plant Brucea antidysenterica. Bruceantin inhibits the peptidyl transferase elongation reaction, resulting in decreased protein and DNA synthesis. Bruceantin also has antiamoebic and antimalarial activity. (NCI04) C274 - Antineoplastic Agent > C1931 - Antineoplastic Plant Product > C1974 - Quassinoid Agent C784 - Protein Synthesis Inhibitor C1907 - Drug, Natural Product Bruceantin (NSC165563) can be extracted from B. javanica and has inhibitory effects on B16 melanoma, colon cancer 38, L1210 and leukemia P388. Bruceantin (NSC165563) can be extracted from B. javanica and has inhibitory effects on B16 melanoma, colon cancer 38, L1210 and leukemia P388.
