Treatment of the pyridazinone derivatives (1a, 1b) with ethyl chloroformate afforded novel carbamates (2a, 2b). Subsequent treatment of 2a, 2b with appropriate amines gave novel benzenesulfonylurea derivatives (3a-i). All these compounds were characterized on the basis of (1)H NMR, IR, Mass spectral data and elemental analysis results. Preliminary biological testing of urea derivatives revealed that some compounds possess significant blood sugar lowering activity. Four compounds (3c, 3f, 3g, and 3h) were found to have promising blood glucose lowering activity and may be used as lead compounds for developing new antidiabetic drugs.
