Claim:
A compound according to formula IAb: wherein Ab represents a pyrazolyl radical substituted with a radical chosen from â€”NHâ€”C(â•O)NY 1 bY 2 b, acylamino(NHâ€”COâ€”R 6 b), and â€”NHâ€”C(â•O)R 6 b, with NY 1 bY 2 b such that either Y 1 b and Y 2 b, which may be identical or different, are chosen from hydrogen and optionally substituted alkyl, cycloalkyl, cycloalkylalkyl, phenyl, naphthyl, phenoxy, phenylalkyl, phenylalkylthio and naphthylalkyl or Y 1 b and Y 2 b form, together with the nitrogen atom to which they are attached, a piperidyl, hexahydrofuran, morpholinyl or morpholinylalkyl radical; A 1 b and A 4 b are hydrogen; A 2 b and A 3 b, which may be identical or different, are chosen from a hydrogen atom, halogen atoms, hydroxyl, alkyl, alkenyl, alkoxy, nitro, cyano, furyl, thienyl, benzothienyl, naphthyl, thianthrenyl, phenyl and phenoxy radicals and a carboxyl radical which is free, salified, esterified with an alkyl radical or amidated with a radical NA 6 bA 7 b such that either A 6 b and A 7 b, which may be identical or different, are chosen from hydrogen and alkyl, alkoxyalkyl, phenoxyalkyl, phenyl, phenylalkyl, cycloalkylalkyl, cycloalkyl, furylalkyl, naphthylalkyl, thienylalkyl, piperidylalkyl, pyridylalkyl, benzothienylalkyl, pyrazolylalkyl, dihydrobenzofuranylalkyl, hexahydropyranylalkyl, ethylenedioxyphenylalkyl and benzimidazolylalkyl radicals, all these radicals being optionally substituted, or A 6 b and A 7 b form, together with the nitrogen atom to which they are attached, a pyrrolidinyl, morpholino or piperazinyl radical, the piperazinyl radical being optionally substituted on the second nitrogen atom with an alkyl radical itself optionally substituted, it being understood that A 2 b and A 3 b can form, with the benzimidazole radical to which they are attached, an optionally substituted 4,5-ethylenedioxybenzimidazole radical or an optionally substituted 4,5-methylenedioxybenzimidazole radical; A 5 b represents a hydrogen atom; all the above radicals containing alkyl, alkenyl, phenyl, phenoxy, furyl, thienyl, piperidyl, pyridyl, pyrazolyl and benzimidazolyl being optionally substituted with one or more radicals chosen from halogen atoms and hydroxyl, cyano, alkyl, alkoxy, amino, alkylamino, dialkylamino, phenylamino, phenylalkylamino, acylamino(NHâ€”COR 6 b), â€”C(â•O)OR 6 b, acyl â€”C(â•O)R 6 b, hydroxyalkyl, carboxyalkyl, phenoxyalkyl, S(O) n -alk, S(O) n â€”NH 2 , S(O) n â€”NH(alk), S(O) n â€”N(alk) 2 , CF 3 , OCF 3 , NO 2 , CN, phenyl, itself optionally substituted with one or more halogen atoms, thienyl, phenoxy, phenylalkoxy, â€”C(â•O)â€”NH 2 , â€”C(â•O)â€”NH(alk) or C(â•O)â€”N(alk) 2 radicals; with n representing an integer from 0 to 2, and R 6 b representing hydrogen, all the phenyl radicals of the above radicals furthermore being optionally substituted with a dioxole radical; or a racemic, enantiomeric or diastereoisomeric isomer form of such compound, or an addition salt with a mineral or an organic acid or with a mineral base of such compound.
