New N-alkylaminocyclitols bearing a 1,2,3-triazole system at different positions of the alkyl chain have been prepared as potential GCase pharmacological chaperones using click chemistry approaches. Among them, compounds 1d and 1e, with the shorter spacer (n = 1) between the alkyltriazolyl system and the aminocyclitol core, were the most active ones as GCase inhibitors, revealing a determinant effect
已经使用点击化学方法制备了在烷基链的不同位置带有1,2,3-三唑系统的新的N-烷基氨基环醇,作为潜在的GCase药理伴侣。其中,化合物1d和1e具有较短的间隔基(n= 1)在烷基三唑基系统和氨基环糖醇核心之间,是最活跃的GCase抑制剂,显示了三唑环位置对活性的决定性作用。此外,SAR数据和计算对接模型表明了亲脂性和酶抑制之间的相关性,并提出了化合物的“扩展”和“弯曲”潜在结合模式。在“弯曲”模式下,活性最高的化合物可以在三唑部分和酶残基Q284之间建立氢键相互作用。在三唑和氨基环糖醇核心之间具有更长间隔基的化合物中,将排除这种相互作用。
