Research Overview
DPDPE
DPDPE is widely cited in opioid pharmacology because it helped establish the functional role of delta-opioid receptors in pain control. Its constrained structure is also used to explore how peptide cyclization changes potency, stability, and tissue selectivity.
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.
