Neurochemical estimations of some new quaternary phenacyl- bromopiperidinium compounds

Considering the fact that N-alkyl substituted quaternary ammonium salts of piperidinium bromide induce brain catecholamine and indoleamine metabolism, we thought it may he valuable to investigate the effects of three selected phenacyl derivatives [I, V and VIII] of piperidine on brain monoamines metabolism in mice [100mg/kg body weight] assuming that these derivatives might alter the brain indoleamine and catecholamine levels differently. Studies are carried out by using HPLC technique. It was found that compound VIII possessed greater neuroleptic activity as compared to compounds I and V
