Abstract: The present invention relates to the use of a substituted quinoline derivative for the preparation of a medicament for the treatment of an infection with a drug resistant Mycobacterium strain wherein the substituted quinoline derivative is a compound according to Formula (Ia) or Formula (Ib) the pharmaceutically acceptable acid or base addition salts thereof, the stereochemically isomeric forms thereof, the tautomeric forms thereof and the N-oxide forms thereof. Also claimed is a composition comprising a pharmaceutically acceptable carrier and, as active ingredient, a therapeutically effective amount of the above compounds and one or more other antimycobacterial agents.

Abstract: The present invention concerns compounds for use as a medicine having the formula the N-oxide forms, the salts, the quaternary amines and stereochemically isomeric forms thereof, wherein R1 represents hydrogen, C1-6alkyl, C1-4alkylthio, C1-4alkyloxy, or halo; R2 represents hydrogen or C1-6alkyl; R3 represents phenyl substituted with halo, cyano, C1-4alkyloxy, C1-4alkylthio, C1-6alkyl, haloC1-6alkyl; 2-thienyl; or 3-thienyl, R4 represents hydrogen; or R2 and R4 form an extra bond, which are active against dermatophytes, and their preparation; it further relates to compositions comprising them, as well as their use as a medicine.

Abstract: The present invention relates to novel substituted quinoline derivatives according to the general Formula (Ia) or the general Formula (Ib) the pharmaceutically acceptable acid or base addition salts thereof, the stereochemically isomeric forms thereof, the tautomeric forms thereof and the N-oxide forms thereof. The claimed compounds are useful for the treatment of mycobacterial diseases, particularly those diseases caused by pathogenic mycobacteria such as Mycobacterium tuberculosis, M. bovis, M. avium and M. marinum. In particular, compounds are claimed in which, independently from each other, R1 is bromo, p=1, R2 is alkyloxy, R3 is optionally substituted naphthyl or phenyl, q=1, R4 and R5 each independently are hydrogen, methyl or ethyl, R6 is hydrogen, r is equal to 0 or 1 and R7 is hydrogen.
