Research Overview
Arenicin-1
Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.
NPY
NPY has been shown in animal studies to protect neurons from excitotoxic injury and to dampen stress-linked cognitive impairment. It is often discussed as a counterbalance to overactive glutamatergic and stress pathways in the brain.
