A series of 1,2,3-triazole analogs of the amino acids l-histidine and l-tryptophan were modeled, synthesized and tested for l-type amino acid transporter 1 (LAT1; SLC7A5) activity to guide the design of amino acid-drug conjugates (prodrugs). These triazoles were conveniently prepared by the highly convergent Huisgen 1,3-dipolar cycloaddition (Click Chemistry). Despite comparable predicted binding modes
一系列的氨基酸的1,2,3-三唑类似物升-组氨酸和升色氨酸进行建模,合成并测试了升型氨基酸转运体1(LAT1; SLC7A5)活性,以指导氨基酸-的设计药物偶联物(前药)。这些三唑可通过高度收敛的Huisgen 1,3-偶极环加成法(点击化学)方便地制备。尽管预测了可比的结合方式,但是三唑相对于其天然氨基酸对应物通常显示出降低的细胞摄取和LAT1结合能力。这些三唑的结构活性关系(SAR)数据对使用氨基酸前药或LAT1抑制剂治疗癌症和脑部疾病具有重要意义。
