intermediate in the non-mevalonate pathway for the biosynthesis of isoprenoids and also serves as a very strong activator of human γδ T cells expressing Vγ9Vδ2 receptors. This paper describes the synthesis of analogues of HMBPP, in which the diphosphate group is replaced by potential isosteric moieties, i.e., carbamate, N-acyl-N‘-oxy sulfamate, or aminosulfonyl carbamate functionalities. The potential of the synthesized
(E)-1-羟基-2-甲基-丁-2-烯基4-二磷酸酯(HMBPP)是非甲羟戊酸途径生物合成类异戊二烯的中间体,也是人类γδT细胞的非常强的激活剂表达Vγ9Vδ2受体。本文描述了HMBPP类似物的合成,其中二磷酸基团被潜在的等排结构部分取代,即氨基甲酸酯,N-酰基-N'-氧基氨基磺酸酯或氨基磺酰基氨基甲酸酯官能团。评估了合成的类似物刺激Vγ9/Vδ2T细胞反应或抑制非甲羟戊酸途径中的最后一种酶GcpE和LytB的潜力。
