synthesized a new scaffold in which the triazole pharmacophore was substituted with a glycine-like amino acid. Structure-activity relationship studies on this scaffold identified a N-(2-(Benzylamino)-2-oxoethyl)benzamide analog WO5m that possesses β-cell protective activity against ER stress with much improved potency (maximal activity at 100% with EC50 at 0.1 ± 0.01 µm) and water solubility.

内质网应激引起的胰腺β细胞功能障碍和死亡在糖尿病的发展中起重要作用。到目前为止,1,2,3-三唑衍生物1是为保护β细胞免受ER应力而保护的仅有的少数结构之一。然而,该化合物具有狭窄的活性范围和有限的水溶性。为了克服这些问题,我们设计并合成了一种新的支架,其中三唑药效团被甘氨酸样氨基酸取代。在该支架上的构效关系研究确定了N-(2-(苄基氨基)-2-氧乙基)苯甲酰胺类似物WO5m,具有对ER应力的β细胞保护活性,且效能大大提高(EC50为0.1时,最大活性为100%) ±0.01 µm)和水溶性。
