研究人员优化了一种双重GLP-1R/GIPR激动剂,用于2型糖尿病和肥胖. 新的,BGM0504,显示显著增强的活性和疗效比提尔泽帕提德,同时保持长半衰期.
科学领域:
- 药理学 药理学是指药理学的学科.
- 分子生物学分子生物学
- 内分泌学 在内分泌学.
背景情况:
- 葡萄糖类-1受体 (GLP-1R) 和依赖葡萄糖的胰岛素型多受体 (GIPR) 的双重激活是2型糖尿病和肥胖症的关键策略.
- 双重激动剂蒂尔泽帕提德 (Tirzepatide) 显示出卓越的疗效,但其部分激动性和延长半衰期的结构基础需要进一步研究.
研究的目的:
- 调查蒂尔泽帕提德与GLP-1R和GIPR相互作用的结构基础.
- 开发一种优化的双重激动剂,具有增强的活性和疗效.
主要方法:
- 分子动力学模拟以探索受体相互作用.
- 在体外和体内实验,以评估的活性和有效性.
- 一种新型双重激素的设计和合成,BGM0504.4.
主要成果:
- 在K20确定了母和GLP-1R/GIPR之间的关键盐桥,在冷EM结构中看不到.
- 与提尔泽帕提德相比,优化的,BGM0504,在激动性活动中呈现出两到三倍的增加.
- 在实验室和动物研究中,BGM0504与提尔泽帕蒂德相比,在实验室和动物研究中显示出更高的疗效,同时保持更长的半衰期.
结论:
- 基于分子动力学的洞察力重新定位了化侧链,从而产生了更强大的双GLP-1R/GIPR激动剂.
- BGM0504代表了对2型糖尿病和肥胖的有希望的治疗候选者,其疗效比提尔泽帕提德更好.
