Quassin isolated from Quassia amara enhanced the host protective immune response by enhancing generation of NO and expression of iNOS both at a protein and at mRNA levels and by upregulating proinflammatory cytokines, TNF-[alpha] and IL-12 (Bhattacharjee et al.
Quassin alters the immunological patterns of murine macrophages through generation of nitric oxide to exert antileishmanial activity.
For example, quassin is soluble in polar solvents like methanol and non-polar solvents like benzene and acetone but not in other non-polar solvents, such as diethyl ether (Budavari 1989); consequently, it is likely that the methanol fraction contained quassin, which caused phagodeterrence.

These quassinoids are interchangeable, as quassin can be reduced to the neoquassins and the neoquassins oxidized to quassin, and can undergo several transformations catalized by mild acidic conditions (Polonsky, 1973).
