N-cycloheptylglycyl-N-(4-carbamimidoylbenzyl)-L-prolinamide

N-cycloheptylglycyl-N-(4-carbamimidoylbenzyl)-L-prolinamide is a synthetic small molecule dipeptide, structurally characterized by a central proline moiety, a terminal cycloheptyl group, and a benzamidine-type (carbamimidoyl) substituent. It was developed as part of a congeneric series of trypsin inhibitors for biochemical research. The compound binds to the S3/S4 specificity pocket of trypsin and related serine proteases, acting as an inhibitor by occupying the active site and blocking substrate access. Its mechanism involves competitive inhibition at the orthosteric site of trypsin. This molecule has been studied primarily in structural biology and enzymology contexts rather than clinical development[6][8].
