Oompounds of formula (I), wherein R
2
represents a hydrogen atom or a C
1-4
alkyl group; q is 1 or 2; A represents a group of formula (a), (b), (c) or (d), wherein Ar represents an optionally substituted phenyl ring or an optionally substituted 5- or 6-membered aromatic heterocyclic ring; or an optionally substituted bicyclic ring system; Ar
1
and Ar
2
each independently represent an optionally substituted phenyl ring or an optionally substituted 5- or 6-membered aromatic heterocyclic ring; and Y represents a bond, —NHCO—, —CONH—, —CH
2
—, or —(CH
2
)
m
Y
1
(CH

)
n
—, wherein Y
1
represents O, S, SO
2
or CO and m and n each represent zero or (I) such that the sum of m+n is zero or 1; providing that when A represents a group of formula (a), any substituent present in Ar ortho to the carboxamide moiety is necessarily a hydrogen or methoxy group; r and s independently represent an integer from zero to 3 such that the sum of r and s is equal to an integer from 1 to 4; V represents a bond, O or S; and salts thereof. Compounds of formula (I) and their salts have affinity for dopamine receptors, in particular the D
3
receptor, and thus potential in the treatment of conditions wherein modulation of the D
3
receptor is beneficial, e.g. as antipsychotic agents.
式(I)的化合物,其中R2代表氢原子或C1-4烷基;q为1或2;A代表公式(a)、(b)、(c)或(d)的基团,其中Ar代表可选取代的苯环或可选取代的5-或6-成员芳香杂环环;或可选取代的双环环系;Ar1和Ar2分别独立地代表可选取代的苯环或可选取代的5-或6-成员芳香杂环环;Y代表键,—NHCO—,—CONH—,—CH2—或—(CH2)mY1(CH2)n—,其中Y1代表O、S、SO2或CO,m和n分别代表零或(I),使得m+n的和为零或1;但当A代表公式(a)的基团时,Ar中与羧酰胺基团相对的任何取代基必须是氢或甲氧基;r和s独立地表示从零到3的整数,使得r和s的和等于从1到4的整数;V代表键、O或S;以及它们的盐。式(I)的化合物及其盐具有亲和力,特别是对D3受体,因此在调节D3受体有益的情况下具有潜在的治疗作用,例如作为抗精神病药物。
