Synthesis, toxicological, and pharmacological assessment of derivatives of 2-aryl-4-(3-arylpropyl)morpholines
The synthesis of nine original morpholine derivatives, i.e.2-aryl-4-(3- arylpropyl)morpholines, is described. The structure of all synthesised derivatives was proved by IR and 1H-NMR, and some of them by 13C-NMR. Acute toxicity studies of the compounds were performed on mice. A comparative pharmacological study of the in vivo effects on the central nervous system was undertaken using the screening tests: hexobarbital induced sleeping time; locomotor activity; and behaviour despair (for antidepressive activity). The most active compound 4-(2-benzoylethyl)-2-phenyl-3-methyl) morpholine 4e was studied for MAO-A and MAO-B inhibition in vitro in rat brain mitochondria preparations.
