1H‐imidazo[4,5‐c]pyridine derivatives has been prepared and evaluated as inotropic agents. The 1H‐imidazo‐[4,5‐b] derivatives were found to be consistently more potent than their isomers in the [4,5‐c] series in isolated guinea pig papillary muscle preparations. Structure‐activity relationships and the species‐dependence of inotropic potencies are discussed.

[EN] A subject-matter of the present invention is a composition exhibiting a pH ranging from 1 to 6.9 and comprising, in an appropriate dyeing medium, at least one coupler and at least one aminopyrazolopyridine oxidation base chosen from the bases of following formula (I): at least one oxidizing agent. The composition of the present invention makes it possible in particular to obtain a colouring with varied, powerful, attractive and not very selective shades which is highly resistant to the various attacks to which hair may be subjected. [FR] La présente invention porte sur une composition présentant un pH se situant dans la plage allant de 1 à 6,9 et comprenant, dans un milieu de coloration approprié, au moins un coupleur et au moins une base d'oxydation d'aminopyrazolopyridine choisie parmi les bases de formule suivante (I): au moins un agent oxydant. La composition de la présente invention permet en particulier d'obtenir une coloration avec des tons variés, puissants, attirants et pas très sélectifs qui sont hautement résistants aux diverses attaques auxquelles le cheveu peut être soumis.
