Abstract
The metabolites of ethyl 4-(3,4-dimethoxyphenyl)-6,7-dimethoxy-2-(1,2,4-triazol-1-ylmeth yl)quinoline -3-carboxylate (1, TAK-603), which is under clinical evaluation as a new type of disease-modifying antirheumatic drug (DMARD), were prepared to confirm their structures and to study their pharmacological properties. Of the metabolites identified, the 4-(4-hydroxy-3-methoxyphenyl) derivative (2c, M-I) was found to have an anti-inflammatory effect in an adjuvant arthritic rat model, although its potency in this model was slightly lower than that of the parent compound.
