Quinoline sulfide derivatives represented by formula (I), (wherein R1 represents a hydrogen atom, a halogen atom, a C1-C6 alkoxy, a C1-C6 alkylthio, or a di(C1-C6-alkyl)amino; R2 and R3 represent each a hydrogen atom or a C1-C6 alkyl; any one of R4 and R5 represents a hydroxyl group with the other representing a hydrogen atom, or alternatively CR4R5 may represent a carbonyl group; m is an integer of 1 or 2; and n is an integer of 0 or 1) prepared by reacting a quinoline-4(1H)-thione derivative with a halogen compound, and having a selective antimicrobial activity against Hp.

Dérivés de sulfure de quinoléine représentés par la formule (I), (dans laquelle R¿1? représente un atome d'hydrogène, un atome d'halogène, C¿1?-C¿6? alkoxy, C¿1?-C¿6? alkylthio ou di-(C¿1?-C¿6?alkyle)amino; R¿2? et R¿3? représentent chacun un atome d'hydrogène ou un C¿1?-C¿6? alkyle; R¿4? ou R¿5? représente indifféremment un groupe hydroxyle, l'autre représentant un atome d'hydrogène, ou bien CR¿4?R¿5? peut représenter un groupe carbonyle; m est 1 ou 2; et n est 0 ou 1), préparés en faisant réagir un dérivé de quinoléine-4(1H)-thione avec un composé halogène et qui présente une activité antimicrobienne sélective contre Hp.
