- 内分泌学 在内分泌学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 阿迪波涅丁是一种由脂肪细胞分泌的激素,通过阿迪波R1和阿迪波R2调节葡萄糖和脂质代谢.
- 肥胖症下降的阿迪波涅丁水平与胰岛素抵抗和2型糖尿病有关.
- 用小分子准AdipoRs为代谢障碍提供了潜在的治疗策略.
研究的目的:
- 识别和描述AdipoR1和AdipoR2.2的口服活性小分子激动剂.
- 在肥胖和2型糖尿病的临床前模型中评估这些激动剂的治疗潜力.
主要方法:
- 在体外结合测定以确认合成激素激剂的AdipoR1和AdipoR2激活.
- 在体内研究使用高脂肪饮食诱导的肥胖小鼠和遗传肥胖的db/db小鼠.
- 评估胰岛素敏感性,葡萄糖耐受性和对治疗的反应寿命.
主要成果:
- 一种新型化合物,AdipoRon,在体外证明与AdipoR1和AdipoR2.2结合.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
