Research Overview
Arenicin-1
Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.
Leu-enkephalin
Leu-enkephalin is a standard tool in opioid receptor and pain-transmission research because it helps distinguish delta- from mu-preferring signaling. Its research value is high, but its clinical utility is limited by rapid enzymatic breakdown and delivery challenges.
