To provide a compound which can be used for the prevention and / or treatment of a disease associated with a 5-HT2B receptor or a 5-HT7 receptor, particularly for the treatment of irritable bowel syndrome (IBS). It is found that an amide derivative having a nitrogenated bicyclic hetero ring such as an indole or a pharmaceutically acceptable salt thereof has a potent antagonistic effect on both of a 5-HT2B receptor and a 5-HT7 receptor. The compound having an antagonistic effect on both of these receptors shows a better pharmacological activity compared to an antagonist alone which is selective to either of these receptors. Therefore, the compound is useful for the prevention and / or treatment of a disease associated with a 5-HT2B receptor or a 5-HT7 receptor, particularly for the treatment of irritable bowel syndrome (IBS).

[Problem] To provide a compound which may be used for the prevention and / or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).[Means for Resolution] It was found that a pyrrole derivative characterized by the possession of a guanidinocarbonyl group or amido group as a substituent group at the 3-position, or a pharmaceutically acceptable salt thereof, has a strong antagonism for both of the 5-HT2B receptor and 5-HT7 receptor. In addition, the compound of the present invention having the antagonistic activity for both of the receptors showed a good pharmacological action in comparison with the case in which an antagonist selective for either one of the receptors was used alone. Based on the above, the compound of the present invention is useful for the prevention and / or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).

Contemplated substituted arylpiperazinyl compounds, and most preferably 18F-Mefway, exhibit desirable in vitro and in vivo binding characteristics to the 5-HT1A receptor. Among other advantageous parameters, contemplated compounds retain high binding affinity, display optimal lipophilicity, and are radiolabeled efficiently with 18F-fluorine in a single step. Still further, contemplated compounds exhibit high target to non-target ratios in receptor-rich regions both in vitro and in vivo, and selected compounds can be effectively and sensitively displaced by serotonin, thus providing a quantitative tool for measuring 5-HT1A receptors and serotonin concentration changes in the living brain.

A series of N-(1,2,3,4-tetrahydronaphthalen-1-yl)-4-aryl-1-piperazinealkylamides was prepared and their affinity for serotonin 5-HT7, 5-HT1A, and 5-HT2A receptors was measured using in vitro binding assays. In relation to 5-HT7 receptor affinity, receptor binding studies indicated that: (i) the optimal alkyl chain length was five methylenes; (ii) an unsubstituted 1,2,3,4-tetrahydronaphthalenyl nucleus was selected for further substitutions; and (iii) the substitution pattern of the aryl ring linked to the piperazine ring played a significant role. Several compound with high affinity for 5-HT7 receptors were identified. Among them, 4-(2-methoxyphenyl)-N-(1,2,3,4-tetrahydronaphthalen-1-yl)-1-piperazinehexanamide (28), 4-(2-acetylphenyl)-N-(1,2,3,4-tetrahydronaphthalen-1-yl)-1-piperazinehexanamide (34), 4-(2-methylthiophenyl)-N-(1,2,3,4-tetrahydronaphthalen-1-yl)-1-piperazinehexanamide (44), 4-(2-hydroxyphenyl)-N-(1,2,3,4-tetrahydronaphthalen-1-yl)-1-piperazinehexanamide (46), 4-(2-methylphenyl)-N-(1,2,3,4-tetrahydronaphthalen-1-yl)-1-piperazinehexanamide (49) were assayed for the 5-HT7 receptor mediated relaxation of substance P-induced guinea-pig ileum contraction. Compounds 28, 44, and 49 behaved as full agonists, compound 34 as a partial agonist, whereas derivative 46 acted as an antagonist.

It was found that a compound according to the following formula:or a pharmaceutically acceptable salt thereof, has a strong antagonism for both the 5-HT2B and 5-HT7 receptors.
