N-甲基-D-天冬氨酸 MSDS(R)-2-(Methylamino)succinic acid
NMDA是兴奋性氨基酸神经递质，只与NMDA受体结合，而不会影响其他谷氨酸受体（如AMPA和Kainate)。NMDA特异性与NMDA受体的NR2亚基结合，刺激非特异性阳离子通道的打开，使Ca
NMDA (0.2 nM) shows significant effects on MF, IF, IL, and EL, respectively, decreasing the mount and intromission frequencies, and shortening the intromission and ejaculation latencies. NMDA and AP-5 significantly, respectively, facilitates and inhibits the ejaculatory behavior during the copulation testing 30 min. Bilateral microinjection of NMDA into PVN significantly increases the baseline LSNA, the peaking increment of LSNA occurred within 5 min from the time of NMDA microinjected into PVN.
