    摘要: There is disclosed an isolated polypeptide and derivatives thereof having protease biological activity for human precursor IL-1β and for a substrate comprising: R1-Asp-R2-R3 wherein R1 and R3 are independently any D or L isomer amino acid, R2 is Ala or Gly, and wherein the specific protease cleavage site is between Asp and R2. Inhibitor compounds, compositions and methods for inhibiting Interleukin 1β protease activity are also disclosed. The inhibitor compounds comprise an amino acid sequence of from 1 to about 5 amino acids having an N-terminal blocking group and a C-terminal Asp residue connected to an electronegative leaving group, wherein the amino acid sequence corresponds to the sequence Ala-Tyr-Val-His-Asp.
