DopamineD3receptor antagonists and partial agonists have been shown to modulate drug-seeking effects induced by cocaine and other abused substances. Compound 6 [PG01037, (N-(4-(4-(2,3-dichlorophenyl)piperazin-1-yl)-trans-but-2-enyl)-4-pyridine-2-ylben zamide)] and related analogues are currently being evaluated in animal models of drug addiction. In these studies, a discrepancy between in vitro binding
This invention relates to novel acylamino cyclopropane derivatives, processes for their preparation, pharmaceutical compositions containing them and their use as modulators of dopamine D3 receptors and for the treatment of anxiety, psychosis, substance abuse, Parkinson's disease, sexual dysfunction, and other central nervous system disorders.
Compounds of formula (I): H.sub.2 N--(CH.sub.2).sub.n --A--(CH.sub.2).sub.m --O--NH.sub.2 and salts thereof are described in which the radical A is C.sub.3 -C.sub.6 cycloalkylene; n is 0 or 1 and, independently thereof, m is 0 or 1; with the provisos that a) the distance between the aminooxy radical H.sub.2 N--O-- and the amino group --NH.sub.2 is at least 3 and not more than 4 carbon atoms and that b) the two radicals H.sub.2 N--(CH.sub.2).sub.n -- and --(CH.sub.2).sub.m --O--NH.sub.2 are not bonded to the same ring carbon of A. The compounds of formula (I) and their salts are ornithine decarboxylase inhibitors.
