Research Overview
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.
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.
