| 描述 | Nitrobenzylthioinosine (NBTI, NBMPR), a specific inhibitor of type 1 equilibrative nucleoside transporter, could regulate the extracellular adenosine concentration and have protective roles in seizures. In vivo, compared to control group, the expression of adenosine A1 receptor protein was increased at 24 h and 72 h after seizure, didn't change at 0 min and 1 w, and decreased at 2 w. In vitro, NBTI decreased the eEPSCs amplitude of pyramidal neurons in hippocampus CA1 region. It also inhibits eEPSCs amplitude on the basis of lower concentration adenosine (50µM), and adenosine A1 receptor inhibitor DPCPX partially reversed this effect[1]. The NBMPR content of plasma from mice injected with NBMPR-P was maximal at about 20 min after injection and declined to < 0.2% of the peak value by 10 h. Erythrocyte-associated NBMPR was also maximal at 20 min, and declined to 11% of the peak value by 10 h after injection. Time courses for the disappearance of NBMPR from plasma and erythrocytes were monoexponential and yielded half-life values of 0.39 h and 0.68 h, respectively, an apparent volume of distribution of 0.61 l/kg, and a clearance of 1.1 l/h per kg[2]. NBMPR can protect CA1 pyramidal neurons from ischemic death without statistically significant effects on adenosine levels or adenosine receptor-mediated inhibition of the proinflammatory cytokine TNF-alpha[3]. NBMPR protected mice against potentially lethal treatment regimens with nebularine, tubercidin or toyocamycin; protection resulted when NBMPR was administered i.p. in advance of or simultaneously with nebularine, but not when NBMPR followed nebularine by 1 hr. Both NBMPR and its 5'-monophosphate protected mice against nebularine lethality when administered s.c[4]. | ||
