AbstractA library of queuine analogues targeting the modification of tRNA isoacceptors for Asp, Asn, His and Tyr catalysed by queuine tRNA ribosyltransferase (QTRT, also known as TGT) was evaluated in the treatment of a chronic multiple sclerosis model: murine experimental autoimmune encephalomyelitis. Several active 7‐deazaguanines emerged, together with a structure–activity relationship involving the necessity for a flexible alkyl chain of fixed length.
摘要 针对奎宁 tRNA 核糖转移酶(QTRT,又称 TGT)催化的 tRNA 对 Asp、Asn、His 和 Tyr 的异接受体的修饰,我们评估了一个奎宁类似物库,用于治疗慢性多发性硬化症模型:小鼠实验性自身免疫性脑脊髓炎。结果发现了几种具有活性的 7-脱氮鸟嘌呤,同时还发现了一种结构-活性关系,即必须有固定长度的柔性烷基链。
