GIP His18突变为Ala增强了其促胰岛素作用。通过用丙氨酸取代GCG中的Arg18同时提高了GLP-1和GIP的活性。使用来自GLP-1的Ala18可能增加GIP活性机率。 Lys20-X: 用Ala取代GLP-1 Lys26会导致亲和力和活性略有下降。在semaglutide中,脂肪酸链连接在该位点,亲和力和活性增 …
GIP and GLP‐1, the two incretin hormones: Similarities and differences
Gastric inhibitory polypeptide (GIP) and glucagon‐like peptide‐1 (GLP‐1) are the two primary incretin hormones secreted from the intestine on ingestion of glucose or nutrients to stimulate insulin secretion from pancreatic β cells.

2023年10月16日 · GLP-1(胰高血糖素样肽-1,又称肠促胰岛素),其关联度较高的靶点为GIP(葡萄糖依赖性促胰岛素释放多肽)和GCG(胰高血糖素)。 GLP-1的功能是刺激胰岛素分泌,抑制胰高血糖素分泌;GIP是双功能激素,在高血糖时促进胰岛素分泌,低血糖时刺激释放胰高血糖素,维稳血糖;GCG可以刺激能量消耗,降低血脂,从而减轻体重。 GLP-1、GIP、GCG于人体内共同完成相应的受体激活,调节糖、脂肪的代谢和平衡。 当前GLP-1方向已有大量药物获 …
Mechanisms of action and therapeutic applications of GLP-1 and dual GIP ...
Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are two incretins that bind to their respective receptors and activate the downstream signaling in various tissues and organs. Both GIP and GLP-1 play roles in regulating food intake by stimulating neurons in the brain’s satiety center.

The Emerging Role of Dual GLP-1 and GIP Receptor Agonists in …
Of the two main incretin hormones released with food ingestion, the actions of glucagon-like peptide-1 (GLP-1) have been exploited for therapeutic benefit. However, little attention has been paid to glucose-dependent insulinotropic polypeptide (GIP) until the recent experimental introduction of dual agonists, or “twincretins”.
