Several new bioanalogues of (+/-)-N-methyl-N-{1-[3-(4-fluorophenoxy) -
2- hydroxy -propyl]piperidin -4- yl} benzothiazol-2-amine (1, sabeluzo
le, CAS 104383-17-7) were prepared by reacting 1,2-epoxy-3-aryloxyprop
anes with 4-arylamninopiperidines. Some of these derivatives showed en
hanced activity in the potassium cyanide hypoxia test and in the pente
trazol convulsion test in mice compared to 1.
