Abstract: The neuropeptide relaxin-3 plays a crucial role in the normal function of the central nervous system and provides a blueprint for molecular mimicry that can drive drug discovery. However, the development of relaxin-3 peptide therapeutic has been limited with the challenges in synthesis and requirement of surgical implantation into the brain providing the limitation of therapeutic development of novel compounds. Introducing a “hydrocarbon-stapling” technology, we first rationally designed and tested a series of stapled peptides installed at the relaxin-3 B-chain sequence. Notably, the successful emergence of a lead stapled peptide demonstrated improved in-vitro and in-vivo pharmacological activity. Further, we aimed to validate the potential for non-invasive intranasal delivery of relaxin-3 and the lead stapled peptide in animal models. Our research findings have suggested that the strategy of intranasal delivery of “stapled” relaxin-3/RXFP3 system has a potential in pursuit of translational pharmacological approaches for eating and stress-related neuropsychiatric disorders.
