Sugar-Coated Peptides: Glycosylation as a New Way to Get Neuropeptides Into the Brain
Attaching sugar molecules (glycosylation) to opioid and other neuropeptides improved their blood-brain barrier penetration and stability, enabling peripherally administered peptides to reach the brain — a new drug delivery paradigm.
Quick Facts
What This Study Found
Glycosylation of opioid and other neuropeptides enhanced BBB penetration, metabolic stability, and analgesic potency after peripheral administration, establishing glycopeptides as a practical strategy for delivering peptide drugs to the brain.
Key Numbers
