Abstract

Three newly synthesized benzamides by the Department of Pharmaceutical Chemistry of the Faculty of pharmacy from the University of Medicine and Pharmacy „Carol Davila” Bucharest were tested in order to determine whether these new molecules have similar effects on the central nervous system as those already in therapeutic use belonging to the same chemical group, such as tiapride (neuroleptic) or lidocaine (local anaesthetic). Tests were carried out on NMRI mice which were given new compounds, conventionally named I5C, I14C, and II5C in a dose of 1/20 of the lethal dose 50% (LD50), as previously determined. They received this treatment daily for 21 days. The evasive–investigating capacity of mice was determined using the platform test, and the motor activity using an Activity cage device. The results have shown that compounds I5C and II5C decrease the investigation capacity of the mice; and compound I5C inhibits motor activity, while II5C stimulates it. Thus we concluded that only compounds I5C and II5C have a neuroleptic potential that might be investigated further.
