Pharmacological studies and synthesis of morpholino alkyl derivatives.

Seven morpholin derivatives were synthesized (compounds 1-7) and their behavioural effects were evaluated; the elements considered were locomotor activity, motor coordination, catalepsy, stereotyped behaviour and antinociception. All the compounds, at doses of 10-20-40 mg/kg/i.p., induced a reduction of all behavioural elements without a significant antinociceptive effect. These results indicate that these morpholin derivatives affect the central nervous system.
