Incretin-based obesity treatments are making remarkable progress, marking a new era in the field of obesity pharmacotherapy. These treatments not only meet the long-standing demands for safety and sustainability in obesity medications but also go beyond, significantly improving complications associated with obesity, such as cardiovascular diseases. This review explores the advancement in obesity treatments through the latest research findings on semaglutide and tirzepatide, two incretin-based obesity treatments currently receiving considerable attention.

베타세포 손상 및 비만 등 제 2형 당뇨병의 근본적인 원인을 치료해 줄 인슐린 유사체가 개발됐다. 도마뱀의 타액성분을 합성시켜 만든 한국릴리의 '바이에타'는 엑세나타이드를 주성분으로, 인크레틴계열 호르몬인 GLP-1과 유사한 작용을 갖고 있다. 국내에서는 지난해 6월 식품의약품안전청으로부터 승인을 받고 같은 해 11월 출시됐다.

GLP-1-based drugs (GLP-1 analogues and DPP IV inhibitors) and incretin mimetics are currently one of the most exciting classes of agents for type II diabetes. GLP-1, a gut peptide, is an incretin that potentiates glucose-dependent insulin release from the pancreas, slows GI-transit and stimulates the proliferation of beta-cells. DPP IV inhibitors act like incretins by inhibiting DPP IV which inactivates GLP-1. LC15-0133 is a competitive, reversible DPP IV inhibitor ($IC_{50}$ = 24 nM, Ki=0.247 nM) with excellent selectivity over other critical human proteases such as DPP II, DPP 8, elastase, trypsin. and urokinase. LC15-0133 showed long half-life and good bioavailability in rats and dogs. Inhibition of plasma DPP IV activity by LC15-0133 was kept more than 50% 24 hours after oral dosing in rats and dogs at 0.1 mg/kg and 0.02 mg/kg, respectively. The Minimum effective doses of LC15-0133 were 0.01 mg/kg for lowering blood glucose excursion during oral glucose tolerance test and 0.1 mg/kg for increasing glucose-induced GLP-1 response in C57BL/6 mice. Repeat oral administration of LC15-0133 for 1 month delayed the progression to diabetes and reduced HbA1c levels in a dose-dependent manner in Zucker Diabetic Fatty rats. In conclusion, LC15-0133 is a novel, potent, selective and orally active DPP IV inhibitor and showed an excellent blood glucose lowering effects in various animal models.

Incretin hormones such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide delay gastric emptying, increasing satiety, and enhance insulin secretion. Two new classes of treatments related to incretin hormones for the management of type 2 diabetes mellitus have emerged: GLP-1 receptor agonists (e.g., exenatide, liraglutide) and the dipeptidyl peptidase-4 (DPP-4) inhibitors (e.g., sitagliptin, saxagliptin, vildagliptin, alogliptin), which prevent the degradation of GLP-1. A MEDLINE search was conducted in order to evaluate the efficacy and safety of incretin-based therapies and publications were reviewed. Data from clinical trials indicated incretin-based treatment showed clinically significant reductions in hemoglobin A1c with low risk of hypoglycemia. Weight reductions were observed with GLP-1 receptor agonists where as DPP-4 inhibitors are weight neutral.
