Chemical structure of quassin

Quassinoids are degraded triterpene lactones (similar to limonoids) of the Simaroubaceae plant family grouped into C-18, C-19, C-20, C-22 and C-25 types.[1] The prototypical member of the group, quassin, was first described in the 19th century from plants of the genus Quassia from which it gets its name.[2] It was isolated in 1937[3] and its structure elucidated in 1961.[4]

They are a biologically potent class of natural products, possessing antimalarial,[5] antifeedant,[6] insecticidal,[7] anti-inflammatory,[8] and anticancer[9] properties. The quassinoid bruceantin reached two separate phase II clinical trials in 1982[10] and 1983[11] but was deemed too cytotoxic to continue.

Other quassinoids include:[12]
