| abstract |
This invention relates to compounds of formula (I) which are glyoxalase I inhibitors, pharmaceutical salts or compositions comprising such compounds, and the use of such compositions and compounds to treat various conditions alleviated by the inhibition of glyoxalase I. Wherein X is N or CH. R2 is H, CF3; or optionally substituted C5-6 aryl, C3-7 cycloalkyl, C5-7 heterocyclyl. R3 is H; or optionally substituted C5-6 aryl, C3-7 cycloalkyl, C5-7 heterocyclyl. Alternatively R2 and R3 together form an optionally substituted C3-4alkylene group wherein L3 and L4 are single bonds thus forming a C5-6 ring fused with the aromatic ring to which L3 and L4 are attached. L3 and L4 are independently selected from a single bond, optionally substituted C1-4 alkylene, -L9YN(OH)C(=O)L10- and -L9C(=O)N(OH)YL10-, wherein L9 and L10 are independently selected from optionally substituted C1-4 alkylene, C5-6 arylene, C1-4 alkylene-C5-6arylene and a single bond, wherein Y is NH or a single bond. |
