Research Overview
Endomorphin-1
Endomorphin-1 is a key research peptide in studies of endogenous mu-opioid signaling and spinal analgesia. Like other peptide analgesics, its main translational hurdles are enzymatic instability, limited oral bioavailability, and delivery across barriers.
Insulin Glargine
Clinical and translational studies support its use as a basal comparator because of prolonged absorption and stable glycemic control. It is heavily used in basal-bolus regimen research and insulin-delivery optimization studies.
