  Synthesis and properties of d-glucosamine N-peptidyl derivatives as substrate analog inhibitors of papain and cathepsin B

  摘要：

  N-peptidyl derivatives of D-glucosamine 7c-7n were synthesized and tested as 7c-7n were synthesized and tested as reversible, substrate analog inhibitors of cysteine and serine-proteases. D-Glucosamine itself showed fair inhibiting properties against cysteine-proteases. Derivatives 7c-7i, designed to improve binding at papain active site, displayed reversible inhibition with K(i) ranging from 67-860-mu-M for papain and from 111-2400-mu-M for cathepsin B. Representative serine proteases were unaffected. No inhibitory activity against human leukocyte elastase was observed for derivatives 7m and 7n bearing very effective peptidyl recognizing units for this enzyme.
