Hence, there is considerable interest in understanding the mechanism underlying the beneficial effects of GLP-I and developing stable and effective GLP-1R agonists. Here, we summarize the presently known mechanism of GLP-I actions, which are mainly through regulating cAMP-PKA signaling pathway; the latest developments in novel clinical GLP-1R agonists are also introduced, which are characterized with multiple properties, such as extended half-life, reduced side-effects, lower production costs and more convenient drug dosing mode. The potential risk of GLP-I-based therapeutics, an often-ignored fact, is also discussed.展开更多

Due to the subdued effects of reducing hemoglobin A1c (HbA1c) on macrovascular complications, controlling other CV risk factors such as hypertension and hyperlipidemia instead of hyperglycemia has been the mainstay treatment to improve CV outcome in patients with type 2 diabetes mellitus (T2DM) until recent years. This review is intended to summarize and compare the results from the available cardiovascular outcome trials (CVOTs) for the two classes of glucose lowering drug: sodium-glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1 RA). The results including the EMPA-REG, CANVAS program and DECLARE-TIMI 58 trials for SGLT2i, and the ELIXA, LEADER, SUSTAIN-6, EXSCEL and HARMONY trials for GLP-1 RA were summarized. The potential mechanisms of these CV beneficial effects and the optimal CV risk reduction treatment in patients with T2DM based on patient risk stratification and evidence from these CVOTs in real-world setting were discussed.展开更多
