2022年2月25日,中国科学院上海药物研究所王明伟/杨德华团队携手徐华强团队在Nature Communications上发表了题为Structural insights into multiplexed pharmacological actions of tirzepatide and peptide 20 at the GIP, GLP-1 or glucagon receptors的研究论文,首次报道了Tirzepatide–GIPR–Gs (3.4 Å)、未酰化Tirzep...
Incretin-based therapies such as GLP-1 receptor agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors are now established in the therapy of type 2 diabetes. New research results, especially with agonists acting on both GIP and GLP-1 receptors, increased the interest in GIP in the therapy of...
GIP和GLP-1是目前发现的两种主要的肠促胰素。相较于人们对GLP-1的了解与关注,GIP一直是位“灰姑娘”,这是为什么? 纪立农教授:“肠促胰素”效应早在上个世纪初就被发现。人们发现胃肠道在食物营养物质的刺激下分泌的一些激素,在血糖调控和代谢方面发挥重要作用,其中包括GLP-1和GIP[2]。在GIP受体基因敲除的啮齿动...

研究表明,健康个体肠促胰素效应刺激的胰岛素分泌约占进餐后胰岛素分泌总量的70%[8]。相对于GLP-1,GIP的肠促胰素作用占整个肠促胰素效应的三分之二左右[8]。 GIP通过胰岛α细胞表面受体发挥对胰高血糖素分泌的调节作用。FPG正常或偏低时,GIP促进胰高血糖素分...
loss and glycemic control with SAR441255, a potent unimolecular peptide GLP-1/GIP/GCG receptor triagonist的文章,研究人员开发了一种靶向GLP-1、GCG和GIP受体的合成肽激动剂SAR441255,在动物模型中显示出优于双重GLP-1/GCG受体激动剂的效果,在健康受试者中,可以改善混合膳食耐受性测试期间的血糖控制且耐受性...
Although bodyweight improvements are observed with both modalities, the most beneficial metabolic effect of targeting the GIP system appears to occur when adding a GIPR agonist to GLP-1RA therapy [56]. The Dual GIP/GLP-1 Hypothesis Activating both the GIP and GLP-1 receptors is especially ...
The present invention relates to compounds which have agonist activity at the glucagon, GIP and GLP-1 receptors, and to their use in the treatment of metabolic disorders.
GLP-1 and GIP are incretin hormones that play important physiological roles in the control of metabolism. They are expressed in the brain, as are their receptors (Cork et al., 2015, Farr Acknowledgements This work was supported by a fellowship to C.H. under the ‘100 Foreign Expert’ ...
This study examined the biological effects of the GIP receptor antagonist, (Pro3)GIP and the GLP-1 receptor antagonist, exendin(9–39)amide. Cyclic AMP production was assessed in Chinese hamster lung fibroblasts transfected with human GIP or GLP-1 receptors, respectively. In vitro insulin release...
