Abstract (en)

[origin: FR2761061A1] The invention concerns compounds of formula (I) in which: A represents a hydrogen atom, a halogen such as fluorine, chlorine or bromine, a cyano group, a C1-4 alkyl group or a C1-4 alkoxy group; R1 and R2 identical or different, represent each a hydrogen atom, a C1-6 alkyl group, a C2-6 alkenyl group, or R1 and R2 together form a C2-6 alkylene or C2-6 alkenylene chain; and R3 represents a hydrogen atom of a C1-4 alkyl group excluding 3-benzenesulphonamido-guanidine hydrochloride. The compounds are useful as medicine, in particular as smooth muscle agents, and more particularly for treating stress incontinence.
