, (2008/06/13)
Described herein are D4 receptor-selective compounds of the general formula: STR1 wherein: A and B are independently selected, optionally substituted, saturated or unsaturated 5-or 6-membered, homo-or heterocyclic rings;X 1 is selected from CH 2, O, NH, S, C=O, CH--OH, CH--N(C 1-4 alkyl) 2, C=CHCl, C= CHCN, N-C 1-4 alkyl, N-acetyl, SO 2 and SO;X. sub.2--is selected from N=, CH 2--, CH=, C(O)--, O--, and S--;R 1 represents C 1-4 alkyl;Y is selected from CH and N;n is 0, 1 or 2;q is 1 or 2;R 2 is C 1-6 alkyl optionally incorporating a heteroatom selected from N, O and S; D is cyclohexane or benzene; andE is a saturated or unsaturated 5-or 6-membered heterocycle incorporating 1, 2 or 3 heteroatoms selected from O, N, and S, wherein E is optionally substituted with 1 or 2 substituents selected from halogen, C 1-4 alkyl and halogen-substituted C 1-4 alkyl;and acid addition salts, solvates and hydrates thereof. Their use as ligands for dopamine receptor identification and in a drug screening program, and as pharmaceuticals to treat indications in which the D4 receptor is implicated, such as schizophrenia, is also described.

Reduction of N-(2-chloro-10,11-dihydrodibenzothiepin-10-yl)formamide with lithium aluminium hydride resulted in the methylamino compound IV.The dimethylamino compound V was obtained by methylation of 10-amino-2-chloro-10,11-dihydrodibenzothiepin with formic acid and aqueous formaldehyde.Substitution reactions of 2,10-dichloro-10,11-dihydrodibenzothiepin with a series of primary and secondary amines afforded the title compounds VI to XXVIII.The bases were transformed to salts and pharmacologically tested.Only the pyrrolidino compound IX (hydrogen succinate VUFB-15551) showed a clear pharmacological profile of a potential antidepressant.

10-(2-Bromoethoxy)-2-chloro-10,11,dihydrodibenzothiepin (X), prepared by two methods, was subjected to substitution reactions with 2-(1-piperazinyl)ethanol, 3-(1-piperazinyl)propanol, 1-methylpiperazine, 3-(1-piperazinyl)propionamide, piperazine, and 1-(ethoxycarbonyl)piperazine and gave the title compounds II-VII.The alcohol II was esterified by treatment with acid chlorides to compounds VIII and IX.Compounds II, V, and VIII proved to be noncataleptic neuroleptic agents and II (clopithepin, VUFB-17 076) was selected for preclinical studies.
