Viral proteases are common targets for drugs: nelfinavir inhibits HIV-1 protease, nirmatrelvir inhibits 3C-like protease of coronaviruses, telaprevir inhibits NS3/4A serine protease of the hepatitis C virus. Proteases of eukaryotic cells may also be targeted: matrix metalloproteinase inhibitors, like tanomastat, can be used as antimetastatic agents. Additionally, neutrophil-expressed elastate, when combined with its activator, eosinophil cationic protein, showed antitumor activity, although that activity was lower in vivo, which is thought to be due to the abundance of protease inhibitors in the tumor environment.

CD95 and H1.0 assay after ELANE administration, from ‘Neutrophil elastase selectively kills cancer cells and attenuates tumorigenesis’ by Cui et al.

We use pNA assays to monitor protease activity. pNA can be characterised as:

  • pNA peptides are a protease substrate
  • Protease cleavage and hydrolysis of the pNA peptides releases p-nitroaniline
  • Free p-nitroaniline is yellow
  • Color intensity is then measured
