The fundamental advantage of peptide-based drugs lies in their inherent biological activity and ability to interact with specific molecular targets in the body. Unlike small molecule drugs, peptides are larger molecules composed of amino acids, which allows them to mimic natural hormones, growth factors, and neurotransmitters. This structural similarity enables them to bind with high affinity and selectivity to their intended receptors, leading to more precise therapeutic effects and often fewer off-target side effects.作者：C Lamers·2022·被引用次数：139—Current challenges inpeptide-based drugdiscovery.
