It is established that the new compound, 9-[2-(4-isopropylphenoxy)ethyl]adenine (9-IPE-adenine) in a dose of 10 mg/kg per day produces neuroprotective effect in rats with brain ischemia model. 9-IPE-adenine decreased the neurologic deficiency 1.2 times more effectively (p < 0.05) than the reference drug mexidol in analogous dose, and had equal effect with this drug at 25 mg/kg per day on the neurologic deficiency and survival of animals. Electrophysiological studies in hippocampal slices in rats showed that 9-IPE-adenine depressed orthodromic population spikes in CA1 area by 42 ± 4%. Non-competitive antagonist of NMDA receptor complex MK-801, in contrast to D-AP5 (competitive NMDA receptor antagonist) and CNQX (competitive AMPA receptor antagonist), enhanced the depressive effect of the new drug more than two times. These ese results are indicative of the ability of 9-IPE-adenine to modulate the ion channel of NMDA receptor complex.

D016194 Receptors, N-Methyl-D-Aspartate A class of ionotropic glutamate receptors characterized by affinity for N-methyl-D-aspartate. NMDA receptors have an allosteric binding site for glycine which must be occupied for the channel to open efficiently and a site within the channel itself to which magnesium ions bind in a voltage-dependent manner. The positive voltage dependence of channel conductance and the high permeability of the conducting channel to calcium ions (as well as to monovalent cations) are important in excitotoxicity and neuronal plasticity.

D016291 Dizocilpine Maleate A potent noncompetitive antagonist of the NMDA receptor (RECEPTORS, N-METHYL-D-ASPARTATE) used mainly as a research tool. The drug has been considered for the wide variety of neurodegenerative conditions or disorders in which NMDA receptors may play an important role. Its use has been primarily limited to animal and tissue experiments because of its psychotropic effects. Dizocilpine,MK-801,MK 801,MK801
