ABSTRACT

Introduction: Type 2 diabetes is a rapid-growing complex chronic metabolic disease characterized by hyperglycemia due to lessened insulin secretion, insulin resistance and hepatic glucose overproduction. GPR119 is a class A of G protein-coupled receptor, expressed on certain enteroendocrine L and K cells in the small intestine and by β-cells within the islets of Langerhans of the pancreas. Activation of GPR119 stimulates the secretion of glucagon-like peptide-1 (GLP-1) in the intestinal tract and glucose-dependent release of insulin in pancreatic β-cells.

Area covered: This review summarized the reported patents on GPR119 agonists from 2014 to present. The authors described the structural features of these novel synthetic molecules and compared their biological activities (including in vitro and in vivo) as potent GPR119 agonists for the treatment of diabetes.

Expert opinion: GPR119 agonists remain the advantage of stimulating both insulin and incretin release in a glucose-dependent manner over other hypoglycemic agents, although some GPR119 agonist clinical candidates have been discontinued in Phase І or Phase II. GPR119 agonists will succeed to be developed as anti-diabetic drugs after accumulated scaffolds of agonists are discovered and the crystallographic structure of GPR119 is elucidated. The synergic effect of GPR119 agonist and DPP-4 inhibitor will also elicit a benefit for the new therapeutic of diabetes.

Article highlights

  • GPR119 has been considered as a promising antidiabetic target.

  • This review summarized the structural feature and bioactivity of synthetic GPR119 agonists reported in the patents from 2014 to present.

  • The patented compounds were classified by a variety of scaffolds.

  • Most compounds showed nanomolar activation of GPR119.

  • The synergic effect of GPR119 agonist and DPP-4 inhibitor is beneficial for development of novel hypoglycaemic drugs based on the GLP-1 related mechanism.
