New substituted (1-thioxo-1,2,3,4-tetrahydro-b-carbolin-9-yl) acetic acids were designed as the inhibitor of AKR1B1 based upon the structure of rhetsinine, a minor alkaloidal component of Evodia rutaecarpa, and twenty derivatives were synthesized and evaluated. The most active compound of the series was (2-benzyl-6-methoxy-1-thioxo-1,2,3,4-tetrahydro-b-carbolin-9-yl) acetic acid (7m), which showed comparable inhibitory activity for AKR1B1 (IC50 = 0.15 mu M) with clinically used epalrestat (IC50 = 0.1 mu M). In the view of activity and selectivity, the most potent compound was (2-benzyl-6-carboxy-1-thioxo1,2,3,4-tetrahydro-b-carbolin-9-yl) acetic acid (7t), which showed strong inhibitory effect (IC50 = 0.17 mu M) and very high selectivity for AKR1B1 against AKR1A1 (311: 1) and AKR1B10 (253: 1) compared with epalrestat.
