This invention creates compounds represented by the following formula (1) which, alone or as a plurality of them simultaneously, act upon serotonin receptors, and thereby provides pharmaceutical compositions that contain these compounds and are useful for the treatment or prevention of diseases which are considered to be induced by the abnormality of central and peripheral serotonin controlling functions. (see formula 1) In the formula, R1 is a hydrogen atom, a lower alkyl group or an aralkyl group; R2 is a hydrogen atom or a specified substituent; n is an integer of 2 to 6; and .alpha. is the following formula (a), (b), (c), (d) or (e). (see formula a) (see formula b) (see formula c) (see formula d) (see formula e) In formulae (a) and (b), R3 is a hydrogen atom or a specified substituent; X is NR10, NCONR11R12, S, SO, SO2 or O; R10 is a hydrogen atom or a specified substituent; R11 and R12 is independently a hydrogen atom or a lower alkyl; Y is a methylene group or a carbonyl group. In formula (c), R4 is a hydrogen atom or a specified substituent; R5 is a hydrogen atom or a specified substituent; k is 0 or an integer of 1 to 3; m is 0 or an integer of 1 to 3; each of A and B is a group which forms a specified ring via a double bond; k + m is an integer of 1 to 3. In formulae (d) and (e), R4 is as defined above; G is CH2, S, O or C=O; D is CH or N; p is an integer of 1 to 3; each of E and J is a group which forms a benzene ring or a pyridine ring via a double bond; R6 and R7 is independently a hydrogen atom or a lower alkyl or the like specified substituent.

L'invention concerne des composés de la formule générale (1) qui agissent seuls ou simultanément en combinaison les uns avec les autres sur des récepteurs de la sérotonine et contribuent ainsi au traitement ou à la prévention de diverses maladies en apparence provoquées par des anomalies dans les systèmes central et périphérique de régulation de la sérotonine. L'invention concerne également des compositions médicinales contenant ces composés. Dans ladite formule (1), R<1> est hydrogène, etc.; R<2> est hydrogène, etc; n est un entier compris entre 2 et 6; et alpha représente les formules (a) à (e). Dans les formules (a) et (b), R<3> est hydrogène, etc; X est NR<10>, etc. (R<10> étant hydrogène, etc.); et Y est méthylène, etc. Dans la formule (c), R<4> est hydrogène, etc; R<5> est hydrogène, etc; k est un entier compris entre 0 et 3; m est un entier compris entre 0 et 3; et A et B sont chacun un groupe formant un noyau spécifique par l'intermédiaire d'une liaison double. Dans les formules (d) et (e), R<3> est tel que défini ci-dessus; G est CH2, etc.; D est CH, etc.; p est un entier compris entre 1 et 3; E et J sont chacun un groupe formant un noyau benzénique ou un noyau pyridique par l'intermédiaire d'une liaison double; et R<6> et R<7> sont l'un et l'autre, indépendamment, hydrogène, etc.
