Patent ID: 8461194

Claim:
A compound of formula (I): wherein A is a σ bond, —X 1 —, or —X 1 —O—X 2 —, in which X 1 and X 2 , which may be identical or different from each other, are an alkyl group having from 1 to 5 carbon atoms, optionally substituted with one or more alkyl groups having from 1 to 5 carbon atoms; Y is H when A is a σ bond, or Y is H, —OH, or —N(R 11 )(R 12 ), when A is —X 1 — or —X 1 —O—X 2 —, in which R 11 is hydrogen, an alkyl group having from 1 to 5 carbon atoms, or R 11 together with R 12 forms a 5- or 6-membered heterocycle, R 12 is hydrogen or an alkyl group having from 1 to 5 carbon atoms, or R 12 together with R 11 forms a 5- or 6-membered heterocycle; R 1 and R 2 , which may be identical or different from each other, are hydrogen or an alkyl group having from 1 to 5 carbon atoms; R 3 and R 4 which may be identical or different from each other, are hydrogen, an alkyl group having from 1 to 5 carbon atoms, an alkoxy group having from 1 to 3 carbon atoms, —OH, —N(R′)(R″), —N(R′)COR″, —CN, —CONR′R″, nitro, or trifluoromethyl; with R′ and R″, which may be identical or different from each other, being hydrogen or an alkyl group having from 1 to 5 carbon atoms; R 8 is hydrogen, an alkyl group having from 1 to 5 carbon atoms, an alkoxy group having from 1 to 3 carbon atoms, a halogen atom, —OH, —N(R′)(R″), —N(R′)COR″, —CN, —CONR′R″, nitro, or trifluoromethyl; with R′ and R″, which may be identical or different from each other, being hydrogen or an alkyl group having from 1 to 5 carbon atoms; R 5 is hydrogen, or an alkyl group having from 1 to 5 carbon atoms, or R 5 together with one from R 6 and R 7 forms a ring having 5 or 6 carbon atoms; R 6 and R 7 , which may be identical or different from each other, are hydrogen, an alkyl group having from 1 to 5 carbon atoms, or together form a group C═O, or one from between R 6 and R 7 , together with R 5 , forms a ring having 5 or 6 carbon atoms, or a pharmaceutically acceptable salt, ester, or prodrug thereof, with the proviso that, when A is a σ bond, and Y, R 1 , R 2 , R 6 , and R 7 are hydrogen atoms, if R 8 is a hydrogen atom, then the group linked to the nitrogen atom in the 1-position of the indazole ring is different from a benzyl group, a 4-chlorobenzyl group, or a 2-4-dichlorobenzyl group, if R 8 is a fluorine atom in the 5-position of the indazole ring, then the group linked to the nitrogen atom in the 1-position of the indazole ring is different from a 5-chloro-2-methoxybenzyl group, and if R 8 is a trifluoromethyl group in the 6-position of the indazole ring, then the group linked to the nitrogen atom in the 1-position of the indazole ring is different from a 2-4-dichlorobenzyl group.
