Research Overview
Insulin Aspart
Research consistently shows faster onset and earlier peak action than regular human insulin. It is commonly studied for meal-time glycemic control and pump-based insulin delivery.
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.
