Synthetic N-[(substitutedsulfamoyl)phenyl]acetamides as moderate chymotrypsin inhibitors.

A facile method has been implemented for the synthesis of different N-substituted sulfamoylacetamides by reacting 4-acetamidobenzenesulfonyl chloride (1) with different alkyl/aralkyl/aryl amines (2a-q) in basic aqueous media under controlled pH to afford -[(Substitutedsulfamoyl) phenyl]acetamides (3a-q) which were confirmed through spectral analysis like FT-IR, EIMS and H-NMR. Moreover, the synthesized derivatives were screened against α-Chymotrypsin. The enzyme inhibitory results revealed that most of the synthesized compounds were found to be moderate enzyme inhibitors.
