Research Overview
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.
Neurotensin
Neurotensin has reproducible analgesic and neuromodulatory effects in preclinical studies, especially in inflammatory and neuropathic pain paradigms. It is not a standard clinical analgesic, but it is a real non-opioid peptide with pain-relevant biology.
