Natural products play a dominant role in pharmaceutical industry, providing resources for the discovery of new drug molecules. Quassinoids are degraded triterpenes reported from the members of the Simarouboidaea subfamily of Simaroubaceae. The importance of quassinoids as antiplasmodial, anticancer and anti-HIV compounds has revived interest in them as potential drug candidates. Its efficacy as combinatorial drug coupled with the structure-activity analysis has reclaimed novel structural leads for new drug development. Quassinoids are categorized into five distinct groups according to their basic skeleton, viz., C-18, C-19, C-20, C-22, and C-25. This present entry reviews the structure, structure-activity
