Patent ID: 7833991

Claim:
A compound represented by the following general formula (1), a pharmacologically acceptable salt thereof, or a prodrug thereof: wherein each of n 1 , n 2 , and n 3 is an integer of 1; each of R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 is independently a hydrogen atom; A 1 is an imidazole ring or an imidazole ring substituted with an alkyl group; A 2 is an imidazole ring which may be substituted with an alkyl group, a hydroxyalkyl group, an alkoxy group, a hydroxy group or a halogen atom; W is a phenylene group or a naphthylene group; X is —(C═O)—, CH 2 or NH; D is a group represented by the following formula (6): —Q—Y—B (6) wherein Q is C═O when X is NH, or NR 12 when X is —(C═O)— or CH 2 , wherein R 12 is a hydrogen atom, or an alkyl group; Y is —(CH 2 ) m4 -z-(CH 2 ) m5 —; wherein each of m 4 and m 5 is an integer of 0 to 2; z is a phenylene group; and B is —NR 25 R 26 wherein each of R 25 and R 26 is, independently a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or cyclic alkyl group having 3 to 6 carbon atoms, wherein one or two or more asymmetric carbon atoms may exist in the compound represented by the general formula (1), where when one asymmetric carbon atom exists, the compound may be in the form of any one of a pure optically active substance represented by the absolute configuration R or S, a mixture thereof in a predetermined ratio, and a racemic mixture thereof or when two or more asymmetric carbon atoms exist, the compound may be in the form of any one of an optically pure diastereomer, a racemic mixture thereof, and a combination thereof in a predetermined ratio, and wherein said prodrug is formed by attachment of an alkoxycarbonyl group or a dialkylaminosulfone group to a nitrogen in an imidazole ring of a compound of general formula (I).
