Cyclic peptideantibiotics Cyclic peptide drugs represent a rapidly evolving class of pharmaceuticals, drawing inspiration from nature's own molecular designs to address challenging disease targets. These molecules, characterized by a closed loop of amino acids, offer distinct advantages over traditional small molecules and linear peptides, including enhanced stability, improved binding affinity, and greater specificity. As an established and growing area of drug development, cyclic peptides are increasingly being explored for their therapeutic potential across a wide range of conditions, from bacterial infections to cancer and inflammatory diseases.

The Rise of Cyclic Peptides in Drug Discovery

The inherent stability of cyclic peptides, stemming from their constrained structure, makes them particularly attractive for therapeutic applications. Unlike linear peptides, which are more susceptible to enzymatic degradation, the cyclic nature of these molecules typically confers greater resistance to proteases. This enhanced metabolic stability can lead to improved pharmacokinetic profiles, allowing for longer circulation times and potentially reduced dosing frequency作者：S You·2024·被引用次数：28—Cyclic peptides are an established class of pharmaceuticals, with the ability to bind to a broader range of protein targets than traditional small molecules ....
