The present invention relates to a compound of formula (I):
wherein A is N or CH; B is N O, or S; R1 is H, a (C1-C4)alkyl group, a methyl(C1-C6)cycloalkyl group or a (C1-C6)cycloalkyl group; R2 is an aryl, an arylmethyl group or a methylheteroaryl group such as methylpyridine and methylthiophene; R3 is absent when B is O or S, or is H or a (C1-C4)alkyl group when B is N; R4 is a (C1-C5)alkyl group or a (C1-C4)cycloalkyl group, each group bearing a carboxylic acid group, and said (C1-C5)alkyl group or (C1-C4)cycloalkyl being optionally substituted by a hydroxyl group, a halogen group or a methoxy group, and when B is N, R3 and R4 can together form a 5- or 6-membered heterocycle substituted by a carboxylic acid group, and optionally substituted by a halogen atom, a hydroxyl group, a methoxy group or a hydroxymethyl group, or anyone of its pharmaceutically acceptable salt, for use in the treatment of a disease characterized by a reduction in macrophage-mediated bacterial killing.
The present invention further relates to a few compounds which are new to the corresponding pharmaceutical composition for the same use.
本发明涉及一种式 (I) 的化合物:
其中 A 是 N 或 CH;B 是 N O 或 S;R1 是 H、(C1-C4)烷基、甲基(C1-C6)环烷基或(C1-C6)环烷基;R2 是芳基、芳甲基或甲基杂芳基,如甲基吡啶和甲基噻吩;当 B 是 O 或 S 时,R3 不存在,当 B 是 N 时,R3 是 H 或(C1-C4)烷基;R4是(C1-C5)烷基或(C1-C4)环烷基,每个基团都带有一个羧酸基,所述(C1-C5)烷基或(C1-C4)环烷基可选择被羟基、卤素基或甲氧基取代,当 B 为 N 时,R3 和 R4 可共同形成一个被羧酸基取代的 5 或 6 元杂环、和任选被卤原子、羟基、甲氧基或羟甲基取代的杂环,或其任何药学上可接受的盐,用于治疗以巨噬细胞介导的细菌杀伤力降低为特征的疾病。
本发明进一步涉及一些化合物,它们是用于相同用途的相应药物组合物的新化合物。
