Disulfide-Isomerase A4 (PDIA4) inhibitors and use thereof for inhibiting pancreatic β-cell pathogenesis and treating diabetes are disclosed. Drug candidates that inhibit PDIA4 with IC50 values ranging from 4 μM to 300 nM are identified. The compounds are highly active in augmenting insulin secretion from pancreatic β-cells. The representative compound No. 8 (4,5-dimethoxy-2-propiolamidobenzoic acid), alone or in combination with metformin, is effective in preserving pancreatic β-cell function, treating and/or reversing, returning blood glucose concentration to a normal level in a diabetic.
披露了二硫键异构酶A4(PDIA4)抑制剂及其用于抑制胰岛β细胞病理发生和治疗糖尿病的用途。已确定抑制PDIA4的药物候选化合物,其IC50值范围从4μM到300nM。这些化合物在增强胰岛β细胞的胰岛素分泌方面具有很高的活性。代表性化合物No. 8(4,5-二甲氧基-2-丙烯酰胺基苯甲酸),单独或与二甲双胍联合使用,对保护胰岛β细胞功能、治疗和/或逆转糖尿病,将血糖浓度恢复到正常水平具有有效性。
