製品説明 | Marizomib (Salinosporamide A) is a novel marine derived proteasome inhibitor which inhibits CT-L β5, C-L β1, and T-L β2 proteasome activities in human erythrocyte-derived 20S proteasomes with IC50 of 3.5 nM, 430 nM, 28 nM. |
---|---|
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.[1] |
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.[1] |

実験の流れ | Proteasome activity is measured in neural stem cells and glioblastoma-derived glioma stem cells at baseline and 2 hours after treatment with marizomib (60 nM). Invasion capability of U-251 MG and D-54 MG cells treated or untreated with 60 nM marizomib for 24 hours is analyzed using Matrigel invasion chambers. |
