title: Effects of a new oxazolidinone derivative AS-8 on serotonin metabolism in the brains of mouse, rat and chick.
abstract: The effect of 5-morpholinemethyl-3-(4-chlorobenzylideneamino)-2-oxazolidin one (AS-8), a potential antidepressant drug, was tested on 5-hydroxytryptamine (5-HT) metabolism in the brains of rat, mouse and chick. The ip administration of AS-8 (25-500 mg/kg) did not modify the cerebral 5-HT level, but significantly increased the level of 5-hydroxyindoleacetic acid (5-HIAA) the main 5-HT metabolite. In animals receiving pargyline (a MAO-A inhibitor which blocks 5-HT catabolism), AS-8 markedly enhanced 5-HT accumulation in the brains of rats and mice, but not chicks. It is concluded that AS-8 is capable of stimulating of 5-HT synthesis at least in the mammalian brain.
