The antidepressant-like effect of 5-(3(-)[((2S)-1,4-benzodioxan-2-ylmethyl)amino]propoxy)-1,3- benzodioxole (MKC-242), a novel 5-HT1A receptor agonist, was studied in the forced swimming test in mice injected i.c.v. with 5,7-dihydroxytryptamine to destroy 5-HT neurons or treated with p-chlorophenylalanine to inhibit 5-HT synthesis. MKC-242 reduced immobility time of mice pretreated with vehicle and these drugs, although it did not affect their locomotor activity. The anti-immobility effect was antagonized by 5-HT1A receptor antagonists such as propranolol and N-tert-butyl-3-(4-(2-methoxyphenyl)piperazin-1-yl)-2-phenylpropana mide. These findings support the hypothesis that postsynaptic 5-HT1A receptors play an important role in the antidepressant-like effect of 5-HT1A receptor agonists.

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.

D013550	Swimming	An activity in which the body is propelled through water by specific movement of the arms and/or the legs. Swimming as propulsion through water by the movement of limbs, tail, or fins of animals is often studied as a form of PHYSICAL EXERTION or endurance.
