Abstract/OtherAbstract:
The development and progression of chronic complications in diabetic patients, such as retinopathy, nephropathy, neuropathy, cataracts, and stroke, are related to the activation and/or overexpression of aldose reductase (ALR2), which is a member of the aldo-keto reductase superfamily. A structure-activity relationship study focused on the C7 position of 1,2,4-benzothiadiazine-1,1-dioxide derivatives was pursued in an attempt to discover ALR2 inhibitors with enhanced potency and selectivity. These studies led to a series of new C7-substituted compounds, which were evaluated for their inhibitory activity against ALR2; they exhibited IC(50) values in the range of 2.80-45.13 nM. Two compounds with a C7-dimethylcarbamoyl and a C7-diethylcarbamoyl substituent, respectively, were found to be the most active and presented excellent selectivity for ALR2 over aldehyde reductase (ALR1). The structure-activity relationship analyses and molecular modeling studies presented herein highlight the importance of hydrophobic and bulky groups at the C7 position for inhibitory activity and selectivity toward ALR2.
