Research Overview

Arenicin-1

Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.

DADLE

DADLE has been studied for analgesic, neuroprotective, and receptor-selective opioid effects in animal and tissue models. It remains important as a mechanistic probe because it is more stable than endogenous enkephalins but still peptide-like in its delivery constraints.
