Identification of Covalent Cyclic Peptide Inhibitors Targeting Protein–Protein Interactions Using Phage Display

Covalent Modifiers

4c15843 Peptide macrocycles are promising therapeutics for a variety of disease indications due to their overall metabolic stability and potential to make highly selective binding interactions with targets. Boyd, Lei Wang, Ralf Bartenschlager, and Matthew Bogyo Journal of the American Chemical Society 2025 DOI: 10.1021/jacs.4c15843

Metabolism of macrocyclic drugs

Metabolite Tales Blog

Not only this, the reduction in rotatable bonds and consequent reduction in susceptibility to metabolism is an additional benefit [4]. The resulting macrocyclic structure was found to be associated with improved metabolic stability and low propensity for P-gp efflux compared to the acyclic analog [13]. Avicenna J Med 12:154–156.
