Our services are designed to streamline the drug development process, offering innovative solutions that accelerate the identification of novel drug candidates with improved efficacy and safety profiles.
Introduction of Peptide Modification Design
Peptides represent a promising class of molecules for drug development due to their high specificity, potency, and low toxicity. However, their inherent limitations, such as poor stability, rapid degradation, and limited bioavailability, pose significant challenges in translating them into viable therapeutic agents. Peptide modification design aims to overcome these obstacles by optimizing the properties of peptides through rational modifications, thereby enhancing their pharmacokinetic properties, target binding affinity, and overall therapeutic potential.
