Hydroquinine

Hydroquinine (Dihydroquinine) is an anti-bacterial agent that inhibits both Gram-positive and Gram-negative bacteria. Hydroquinine inhibits the growth of multidr_ug-resistant pseudomonas aeruginosa via the suppression of the arginine deiminase pathway genes. Hydroquinine inhibits Plasmodium falciparum and Plasmodium berghei. Hydroquinine displays anti-malarial and demelanizing activities. Hydroquinine effectively induces specific RND-type efflux pump systems in Pseudomonas aeruginosa, particularly the MexCD-OprJ and MexXY efflux pumps. Hydroquinine inhibits Pseudomonas aeruginosa adhesion and biofilm formation. Hydroquinine serves as a precursor for derivatives such as C9 epihydroquinine, 9-acetoxy-10,11-dihydroquinine, and 10,11-dihydroquinine monohydrochloride[1][2][3].
