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.
Statherin
Statherin has been extensively studied as a key regulator of enamel mineral equilibrium and pellicle biology. It is used in biomimetic dentistry research to model or improve enamel protection and remineralization.
