Advances in the research of long-acting strategy of insulin and GLP-1 analogs

Insulin as well as glucagon-like peptide 1(GLP-1)and its analogs are commonly used in treating type II diabetes. Both insulin and GLP-1 are endogenous peptides, and have advantages such as high efficiency and selectivity. However, there are some disadvantages to using regular insulin with slow effect, short-time effect and risk of hypoglycemia. Due to the elimination of kidneys and the metabolism of enzymes, the half-life of GLP-1 is so short that neither of them can stabilize glucose. Therefore, it is of great significance to study the long-acting strategy of insulin and GLP-1. Based on the long-acting strategy and pharmacological assessment of peptide drugs, this paper reviewed the latest progress of the related drugs that already on the market and under research to provide references for the design of novel long-acting insulin and GLP-1 analogs.
