Triazolyl phenylalanine and tyrosine‐aryl C‐glycoside hybrids were readily synthesized via microwave‐assisted Cu(I)‐catalyzed azide‐alkyne 1,3‐dipolar cycloaddition in high yields. Successive enzymatic assay identified the synthesized glycoconjugates as novel PTP1B inhibitors with low micromole‐ranged inhibitory activity and at least several‐fold selectivity over other homologous PTPs tested. In addition
通过微波辅助的Cu(I)催化的叠氮化物-炔烃1,3-偶极环加成反应可轻松合成三唑基苯丙氨酸和酪氨酸-芳基C-糖苷杂化物。连续的酶法分析鉴定出合成的糖缀合物是新型PTP1B抑制剂,具有低微摩尔范围的抑制活性,并且比其他测试的同源PTP具有至少几倍的选择性。另外,发现葡糖基部分上的苄基对抑制PTP1B至关重要。
