Research Overview
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.
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.
