Research Overview
Orexin-A
Preclinical studies link orexin signaling to arousal, learning, and memory consolidation, making orexin-A a candidate for cognition-related research. It is not an approved cognitive enhancer and remains an experimental peptide.
Arenicin-1
Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.
