Harnessing the Therapeutic Potential and Biological Activity of Antiviral Peptides

Von Wiley-VCH zur Verfügung gestellt

Peptides are ideal candidates for the development of antiviral therapeutics due to their specificity, chemical diversity and potential for highly potent, safe, molecular interventions. By restricting conformational freedom and flexibility, cyclic peptides frequently increase peptide stability. Viral targets are often very challenging as their evasive strategies for infectivity can preclude standard therapies. In recent years, several peptides from natural sources mitigated an array of viral infections. In parallel, short peptides derived from key viral proteins, modified with chemical groups such as lipids and cell-penetrating sequences, led to highly effective antiviral inhibitor designs. These strategies have been further developed during the recent COVID-19 pandemic caused by the novel coronavirus SARS-CoV-2. Several anti-SARS-CoV-2 peptides are gaining ground in pre-clinical development. Overall, peptides are strong contenders for lead compounds against many life-threatening viruses and may prove to be the key to future efforts revealing viral mechanisms of action and alleviating their effects.
