چکیده

7-Nitro indazole (25-100 mg/kg i.p.), an inhibitor of neuronal nitric oxide (NO) synthase, attenuated the severity of pilocarpine (300 mg/kg i.p.)-induced seizures in mice. This indicates that the decreased neuroexcitability of the central nervous system (CNS) following administration of 7-nitro indazole may be due to inhibition of neuronal NO synthase, implying that NO acts as an excitatory and proconvulsant factor in the CNS.

7-Nitro indazole, a neuron-specific nitric oxide synthase inhibitor, produces amnesia in the chick.

7-Nitro indazole (7-NI), which is selective for the neuronal isoform of nitric oxide synthase (NOS), was tested in a passive avoidance task in the chick. Injection of 50 mg/kg i.p. pretraining had amnesic effects for the task when tested 30 min, 2 or 24 hr after training. Injections post-training had no effect. Because 7-NI does not inhibit the endothelial isoform of NOS, it does not affect blo...

Effects of Nitric Oxide Synthase Inhibitors, 7-ni and L-name, on Content of Reduced Glutathione in Experimental Model Huntington′s Disease

The etiology of neuronal death in neurodegenerative diseases, including Huntington′s disease (HD), is still unknown. There could be a complex interplay between altered energy metabolism, excitotoxicity and oxidative stress. Our aim was to examine the effects of intrastriatal injection of a selective inhibitor of neuronal nitric oxide synthase, 7 nitro indazole (7-NI), and non-specific potent ni...

Halothane minimum alveolar anesthetic concentration and neuronal nitric oxide synthase activity of the dorsal horn and the locus ceruleus in rats.

UNLABELLED There is some evidence of a relationship between nitric oxide and pain control pathways. However, it is still controversial whether nitric oxide synthase (NOS) inhibitors affect minimum alveolar anesthetic concentration (MAC). We examined the effects of 7-nitro indazole (7-NI), a selective neuronal NOS (nNOS) inhibitor, on halothane MAC. With nicotinamide adenine dinucleotide phospha...

Activities of 7-nitroindazole and 1-(2-(trifluoromethylphenyl)-imidazole independent of neuronal nitric-oxide synthase inhibition.

7-Nitroindazole (NI) is a widely used inhibitor of neuronal nitricoxide synthase (nNOS) used to study the role of the neuronal NO pathway in the nervous system. 7-NI prevents convulsions, including 2-amino-4-methylphosphinobutyric acid (glufosinate)-induced convulsions, in experimental models. Herein, we examined nNOS involvement in glufosinate-induced convulsions and the specificity of 7-NI fo...
