Key Strategies in Cyclic Peptide Drug Development

Cyclic peptides provide strong target affinity and conformational control, yet development often faces hurdles like permeability issues and metabolic instability. This article outlines modular support from design review to preclinical preparation, including scaffold optimization, synthesis via solid-phase peptide synthesis (SPPS), SAR expansion, and developability assessments. Teams can align workflows to specific stages, such as hit generation or lead refinement, to address common risks effectively.
