Abstract

Parasitic diseases are responsible for significant morbidity and mortality among vulnerable populations in developing countries where poor sanitation and lack of access to health care foster disease transmission. Current drugs are not sustainable for long-term treatment due to high toxicity, resistance issues, prohibitive prices, or inadequate methods of administration. There is an urgent need for new therapeutics that will address these issues. This mini-review discusses the potential of targeting therapeutically relevant protein-protein interactions with peptide inhibitors as anti-parasite drugs.


INTRODUCTION

Protein–protein interactions
Protein–protein interactions (PPIs) are physical contacts established between two or more proteins that can occur in response to biochemical signals. These interactions result in a functional output that is unique to the protein complex. By this general definition, PPIs are intimately involved in almost all biological processes, including inter- and intracellular signal transduction, gene expression, cell proliferation, and programmed cell death. Therefore, PPIs are important phenomena for basic scientific research and are also attractive targets for human therapeutics. The number of characterized PPI targets that are linked to human disease is rapidly increasing and targeting PPIs for drug d
