Drugs, in particular, pyrazole derivatives represented by general formula (I) which have a calcium release-dependent calcium channel inhibitory effect and medicinal compositions, in particular, calcium release-dependent calcium channel inhibitors containing the above compounds as the active ingredient, in said formula each symbol has the following meaning: B: phenylene, a nitrogen- containing, divalent, saturated ring group, or an optionally alkylated, monocyclic, divalent heteroaromatic ring group; X: -NR1-CR2R3-, -CR2R3-NR1-, - NR1-SO2-, -SO2-NR1- or -CR4=CR5-; and A: phenyl optionally having one or more substituents; mono-, di- or tricyclic fused heteroaryl optionally having one or more substituents; cycloalkyl optionally having one or more substituents; a nitrogen-containing, saturated ring group optionally having one or more substituents; lower alkenyl optionally having one or more substituents; lower alkynyl optionally having one or more substituents; or alkyl optionally having one or more substituents.

L'invention concerne des médicaments, notamment, des dérivés de pyrazole, représentés par la formule générale (I), qui ont un effet inhibiteur du canal calcique dépendant de la libération de calcium, ainsi que des compositions médicinales, notamment, des inhibiteurs du canal calcique dépendant de la libération de calcium, contenant lesdits composés en tant que principe actif. Dans cette formule (I), B représente phénylène, un groupe à noyau saturé, divalent, contenant de l'azote, ou un groupe à noyau hétéroatomique, divalent, monocyclique, éventuellement alkylé; X représente -NR<1>-CR<2>R<3>-, -CR<2>R<3>-NR<1>-, -NR<1>-SO2-, -SO2-NR<1>- ou -CR<4>=CR<5>; et A représente phényle ayant éventuellement un ou plusieurs substituants; hétéroaryle condensé mono, di ou tricyclique ayant éventuellement un ou plusieurs substituants; cycloalkyle ayant éventuellement un ou plusieurs substituants; un groupe à noyau saturé, contenant de l'azote ayant éventuellement un ou plusieurs substituants; alcényl inférieur ayant éventuellement un ou plusieurs substituants; alkynyle inférieur ayant éventuellement un ou plusieurs substituants; ou alkyle ayant éventuellement un ou plusieurs substituants.
