BRIDGED SIX-MEMBERED RING COMPOUNDS

The invention relates to compounds of formula (I), wherein R1, R2, R1a, R2a, R3, R4, A, B, X, W and n are as defined in the description, and pharmaceutically acceptable salts of such compounds. These compounds are useful as calcium channel blockers.

SIGMA RECEPTOR BINDER CONTAINING INDANONE DERIVATIVE

The present invention provides an indanone derivative and an excellent sigma receptor binding agent comprising an indanone derivative. More specifically, it provides a sigma receptor binding agent comprising an indanone derivative represented by the following formula, a pharmacologically acceptable salt thereof or a hydrate of them. In the formula (I), R1, R2, R3 and R4 are the same as or different from each other and each represents hydrogen atom, a halogen atom, hydroxyl group, nitrile group, a C1-6 alkyl group which may be substituted, a cycloalkyl group having three to eight carbon atoms which may be substituted, a C1-6 alkoxy group which may be substituted, a cycloalkoxy group having three to eight carbon atoms which may be substituted, an acyl group having one to six carbon atoms which may be substituted, a C1-6 alkoxycarbonyl group which may be substituted, a C1-6 alkylaminocarbonyloxy group which may be substituted, a di(C1-6 alkyl)aminocarbonyloxy group which may be substituted, nitro group, an amino group which may be substituted, an amido group which may be substituted, mercapto group or a thio-C1-6 alkoxy group which may be substituted, and further R1 with R2, R2 with R3, or R3 with R4 may together form an aliphatic ring, an aromatic ring, a heterocyclic ring or an alkylenedioxy ring; the partial structure: represents a group represented by >CH-CH2-, >C=CH- or >C(-R7)-CH2-; m represents an integer of 0 or 1 to 5; and R5 represents hydrogen atom, a C1-6 alkyl group which may be substituted, a C2-6 alkenyl group which may be substituted, a C2-6 alkynyl group which may be substituted, a cycloalkyl group having three to eight carbon atoms which may be substituted, a 2,2-(alkylenedioxy)ethyl group or a group represented by the formula: (wherein the ring C represents benzene ring, an aliphatic ring or a heterocyclic ring; R6s are the same as or different from each other and each represents hydrogen atom, a halogen atom, hydroxyl group, nitrile group, a C1-6 alkyl group which may be substituted, a C2-6 alkenyl group which may be substituted, a C2-6 alkynyl group which may be substituted, a cycloalkyl group having three to eight carbon atoms which may be substituted, a C1-6 alkoxy group which may be substituted, a C1-6 alkoxyalkoxy group which may be substituted, an aryloxy group which may be substituted or an aralkyloxy group which may be substituted, and further two of R6s may together form an aliphatic ring, an aromatic ring, a heterocyclic ring or an alkylenedioxy ring; R7 represents a halogen atom, hydroxyl group, a C1-6 alkyl group which may be substituted, a C1-6 alkoxy group, nitrile group, a halogeno-C1-6 alkyl group, a hydroxyl-C1-6 alkyl group, a cyano-C1-6 alkyl group, an amino-C1-6 alkyl group, nitro group, azide group, an amino group which may be substituted, a carbamoyl group which may be substituted, a carboxyl group which may be substituted, mercapto group or a thio-C1-6 alkoxy group; and n represents an integer of 1 to 5), provided that 1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]methylpiperidine, a pharmacologically acceptable salt thereof or a hydrate of them are excluded.
