Dpp4抑制 剂 Dipeptidyl peptidase 4 (DPP-4), also recognized as DPP4, DPPIV, or CD26 (cluster of differentiation 26), is a significant enzyme that plays a multifaceted role within the human body. This serine exopeptidase, primarily found anchored to the cell surface as a transmembrane glycoprotein, is also present in a soluble, circulating form within the blood. Its enzymatic activity involves the cleavage of a dipeptide from the N-terminus of various peptides, particularly those with proline or hydroxyproline as the penultimate residue. This catalytic function allows DPP-4 to regulate the bioactivity of numerous peptides by their cleavage and inactivation.

The Crucial Role of Dipeptidyl Peptidase 4 in Metabolic Regulation

A principal function of dipeptidyl peptidase 4 lies in its interaction with incretin hormones, most notably glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). These incretins are crucial regulators of glucose homeostasis, released from the gastrointestinal tract following nutrient intake. They stimulate insulin secretion and suppress glucagon release in a glucose-dependent manner, thereby helping to lower blood sugar levelsDipeptidyl peptidase 4 (DPP4) is a widely expressed, serine protease which regulates the bioactivity of many peptides through cleavage and inactivation .... DPP-4 acts to rapidly inactivate these beneficial incretin hormones, shortening their duration of action.The Roles of Dipeptidyl Peptidase 4 (DPP4) and DPP4 Inhibitors ... - NIH This inactivation is achieved by cleaving the N-terminal dipeptide of GLP-1 and GIP.

Dipeptidyl Peptidase 4 Inhibitors: A Glimpse into Advanced Diabetes Management

The understanding of DPP-4's role in incretin degradation has led to the development of a class of drugs known as Dipeptidyl peptidase 4 (DPP-4) inhibitors, often referred to as "gliptins." These prescription medicines are designed to block the enzyme dipeptidyl peptidase-4 by inhibiting its activity. By preventing DPP-4 from inactivating GLP-1 and GIP, these inhibitors effectively prolong the action of these incretin hormones. This leads to enhanced glucose-dependent insulin secretion and reduced glucagon secretion, ultimately contributing to improved glycemic control in individuals with type 2 diabetes mellitus.

Dipeptidyl peptidase 4 (DPP-4) inhibitors are widely utilized as a treatment to lower blood sugar levels in people with type 2 diabetes作者：CF Deacon·2020·被引用次数：412—Overall, DPP4ihave a favourable therapeutic profileand are safe and effective in the majority of patients with type 2 diabetes mellitus.. They are considered valuable pharmaceutical agents due to their generally favorable therapeutic profile, demonstrating both safety and efficacy in the majority of patients. These medications are often employed either as monotherapy when metformin is unsuitable, or in combination with other antidiabetic agents. The potential for DPP-4 inhibitors to provide Efficacy as monotherapy or combination therapy has made them a cornerstone in modern diabetes management strategies.
