Proteasome inhibitor research

Pristimerin (CAS: 1258-84-0) is a naturally occurring quinonemethide triterpenoid isolated primarily from medicinal plants of the Celastraceae family, such as Celastrus paniculatus, Maytenus ilicifolia, and Salacia oblonga.It belongs to the friedelane-type triterpenoids, characterized by a quinonemethide moiety that contributes to its potent biological activity. This rare structural feature makes Pristimerin a valuable compound for pharmacological and biochemical research.
