[Anti-anoxic effect of 4-(o-benzlphenoxy)-N-methylbutylamine hydrochloride (MCI-2016)]. 1983

A Tobe, and M Egawa, and N Hashimoto

Anti-anoxic effects of MCI-2016 were compared with those of drugs for cerebrovascular diseases, tricyclic antidepressants and physostigmine in mice. Minimal effective doses of MCI-2016 which significantly increased the survival time or gasping duration were 12.5 mg/kg, p.o. for hypoxia, 50 mg/kg, p.o. for KCN-induced anoxia, and 100 mg/kg, p.o. for decapitation-induced gasping. As a whole, these effects of MCI-2016 were superior to those of reference drugs for cerebrovascular diseases. MCI-2016 was also shown to be effective under a consecutive administration schedule. In marked contrast to the effect of MCI-2016, tricyclic antidepressants significantly shortened the survival time under hypoxia. Considering that atropine shortened and physostigmine markedly increased the survival time under hypoxia, involvement of anti-cholinergic action may be postulated for the shortening effect of tricyclic antidepressants. The anti-hypoxic effect of MCI-2016 as well as physostigmine was diminished by atropine treatment. Furthermore, MCI-2016 exhibited a combination effect with physostigmine at optimal doses. Although the influence of norepinephrine uptake inhibitory action on the hypoxic condition are not clear in the present study, these results may suggest that activation of CNS cholinergic system is involved as one of the causative mechanisms for anti-anoxic effect of MCI-2016.

D008297 Male Males
D010830 Physostigmine A cholinesterase inhibitor that is rapidly absorbed through membranes. It can be applied topically to the conjunctiva. It also can cross the blood-brain barrier and is used when central nervous system effects are desired, as in the treatment of severe anticholinergic toxicity. Eserine

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000928 Antidepressive Agents Mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions. Several MONOAMINE OXIDASE INHIBITORS are useful as antidepressants apparently as a long-term consequence of their modulation of catecholamine levels. The tricyclic compounds useful as antidepressive agents (ANTIDEPRESSIVE AGENTS, TRICYCLIC) also appear to act through brain catecholamine systems. A third group (ANTIDEPRESSIVE AGENTS, SECOND-GENERATION) is a diverse group of drugs including some that act specifically on serotonergic systems.

D000929 Antidepressive Agents, Tricyclic Substances that contain a fused three-ring moiety and are used in the treatment of depression. These drugs block the uptake of norepinephrine and serotonin into axon terminals and may block some subtypes of serotonin, adrenergic, and histamine receptors. However, the mechanism of their antidepressant effects is not clear because the therapeutic effects usually take weeks to develop and may reflect compensatory changes in the central nervous system.
