| 產品描述： | Epoxomicin (BU-4061T) is an epoxyketone-containing natural product and a potent, selective and irreversible proteasome inhibitor. Epoxomicin covalently binds to the LMP7, X, MECL1, and Z catalytic subunits of the proteasome and potently inhibits primarily the chymotrypsin-like activity. Epoxomicin can cross the blood-brain barrier. Epoxomicin has strongly antitumor and anti-inflammatory activity |

| 體內研究： |
Epoxomicin (0.063-1 mg/kg; intraperitoneal injection; once daily; for 9 days; male BDFX mice) treatment shows significant antitumor effect with the minimumeffective dose of 0.13mg/kg/day. Epoxomicin also effectively inhibits NF-κB activation in vitro and potently blocks in vivo inflammation in the murine ear edema assay. Epoxomicin is injected into adult rats over a period of 2 weeks. After a latency of 1 to 2 weeks, animals developed progressive Parkinsonism with bradykinesia, rigidity, tremor, and an abnormal posture. Postmortem analyses shows striatal dopamine depletion and dopaminergic cell death with apoptosis in the substantia nigra pars compacta. |
