2型糖尿病与胰岛素抵抗、胰岛β细胞胰岛素分泌受损和非酒精性脂肪性肝病有关。组织特异性的SWELL1消融影响了脂肪、骨骼肌和内皮细胞中的胰岛素信号传导,影响了β细胞的胰岛素分泌和血糖控制。在这里,我们展示了在小鼠和人类糖尿病中,脂肪和β细胞中的ICl,SWELL和SWELL1蛋白质被降低。通过结合冷冻电镜、分子对接、药物化学和功能研究,我们定义了一种结构活性关系,以合理设计SWELL1通道抑制剂(DCPIB/SN-401)的活性衍生物,这些衍生物结合SWELL1六聚体复合物,通过SWELL1依赖机制恢复SWELL1蛋白质、质膜转运、信号传导、血糖控制和胰岛素分泌。在体内,SN-401恢复小鼠糖尿病的血糖控制,减少肝脏脂肪变性/损伤,改善胰岛素敏感性和胰岛素分泌。这些发现表明,SWELL1通道调节剂改善了2型糖尿病中依赖SWELL1的全身代谢,代表了糖尿病和非酒精性脂肪性肝病的首个一类治疗方法。
Type 2 diabetes is associated with insulin resistance, impaired pancreatic β-cell insulin secretion, and nonalcoholic fatty liver disease. Tissue-specific SWELL1 ablation impairs insulin signaling in adipose, skeletal muscle, and endothelium, and impairs β-cell insulin secretion and glycemic control. Here, we show that ICl,SWELL and SWELL1 protein are reduced in adipose and β-cells in murine and human diabetes. Combining cryo-electron microscopy, molecular docking, medicinal chemistry, and functional studies, we define a structure activity relationship to rationally-design active derivatives of a SWELL1 channel inhibitor (DCPIB/SN-401), that bind the SWELL1 hexameric complex, restore SWELL1 protein, plasma membrane trafficking, signaling, glycemic control and islet insulin secretion via SWELL1-dependent mechanisms. In vivo, SN-401 restores glycemic control, reduces hepatic steatosis/injury, improves insulin-sensitivity and insulin secretion in murine diabetes. These findings demonstrate that SWELL1 channel modulators improve SWELL1-dependent systemic metabolism in Type 2 diabetes, representing a first-in-class therapeutic approach for diabetes and nonalcoholic fatty liver disease.
