Broad Spectrum Anti-viral Peptides

HKU
Overview

A series of broad spectrum antiviral peptides and composition including therapeutically effective amounts of the antiviral peptides along with a pharmaceutically acceptable carrier were developed. The antiviral compositions show a strong broad spectrum antiviral effect without resulting to viral resistance. These antiviral peptides are effective in treating diseases caused by viral infections, particularly respiratory viruses.

Problem addressed

Viral infection annually still causes millions of deaths globally. Taking Influenza virus as an example, annually causes over 3 to 5 million cases of severe illness with about 0.25 million deaths globally. In addition, resistance was found in most of current anti-viral drugs so it is essential to develop a new broad spectrum anti-viral drug.

Innovation
  • The duo function anti-viral peptides provide effective and broad-spectrum of anti-viral effect by blocking viral entry and preventing the viral replication through inhibiting the endosomal acidification
  • The studies indicated that there is low possibility of inducing drug-resistance viruses
  • The metabolic toxicity for the peptides is low and did not induce significant change of body weight in the animal model
Key impact
  • The duo function peptides provide effective and broad-spectrum of anti-viral effect to Influenza A, influenza B and SARS-CoV-2
  • Low possibility of inducing drug-resistance viruses
  • Low metabolic toxicity for these anti-viral peptides in the animal model
Application
  • Broad-spectrum antiviral agent, particular to those pH-dependent viruses such as influenza A, influenza B, SARS-CoV
