A new class of shape-modified nucleosides is introduced. These novel "fleximers" feature the purine ring systems of adenosine, inosine, and guanosine split into their individual imidazole and pyrimidine components (as in 1-3). This structural modification serves to introduce flexibility into the nucleoside while still retaining the elements essential for recognition. As a consequence, these novel fleximers
引入了一类新的形状修饰的核苷。这些新颖的“挠性分子”具有腺嘌呤,肌苷和鸟苷的嘌呤环系统,分为各自的咪唑和嘧啶组分(如1-3所示)。这种结构修饰用于将柔韧性引入核苷,同时仍保留识别所必需的元素。结果,这些新颖的挠性基团应该被用作研究探针-辅酶结合位点以及核酸和蛋白质相互作用的生物探针。描述了它们的设计和综合。
