4、r kainate-mediates excitotoxicity. Neu2000 inhibits the electrophysiologic response of cultured corticalneurons to 300 M NMDA in a concentration-dependent manner, indicating that the effect is mediated by aspecific action at NMDA receptors. The Neu2000 dose-response has an IC50 of 35.385.94 M and Hi

Neu2000 (100 M) significantly reduces the maximal NMDA response by58.312.72% (n=5) and the EC50 values of NMDA from 18.881.85 to 9.920.17 M (n=5, P 1.體內研究 Pharmacokinetic analysis reveals that the half-life of Neu2000 is 1.42, 2.14, and 1.79h followingintraperitoneal ad

11、The pharmacokinetic profile of Neu2000 in normal rats is examined using intraperitoneal (ip) route ofAdministration 2 administration. Rats are anesthetized by ether inhalation and the femoral artery cannulated. Rats are placedinto cages for 1h and then receive injections (10, 25, or 50mg/kg ip, n=6

12、per dose) of Neu2000 dissolved insterile saline. Blood is collected from the femoral artery at 15, 30, 60, 120, 240, 480, and 1440min followinginjection. Plasma aliquots of 50L are spiked with 100L of internal standard solution (Neu2000IS, 10g/mLin acetonitrile). After vortex mixing for 1min, the sa
