How to use

In Vitro:

Marizomib inhibits the proteasome activity, proliferation, and invasion of glioma cells. Meanwhile, free radical production and apoptosis induced by marizomib can be blocked by antioxidant N-acetyl cysteine.

In Vivo:

In animal studies, marizomib distributes into the brain at 30% of blood levels in rats and significantly inhibits (>30%) baseline chymotrypsin-like proteasome activity in brain tissue of monkeys. Encouragingly, the immunocompromised mice, intracranially implanted with glioma xenografts, survives significantly longer than the control animals when treated with marizomib.
