A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe–Ziegler cyclization. In addition to an adenosine and a guanosine mimic, analogues of the noncanonical xanthosine, isoguanosine, and 2-aminoadenosine were also synthesized and found to be emissive. Isothiazolo 2-aminoadenosine, an adenosine
使用涉及关键的索普-齐格勒环化的发散途径,制备了一系列均由异噻唑并[4,3- d ]嘧啶核组成的放射状核糖核苷嘌呤模拟物。除了腺苷和鸟苷模拟物外,还合成了非经典的黄嘌呤,异鸟苷和2-氨基腺苷的类似物,并且发现它们是发光的。发现异硫唑酮2-氨基腺苷是一种腺苷替代物,其特别发射并被腺苷脱氨酶有效地脱氨基。腺苷脱氨酶与每种类似物结合天然腺苷的竞争性研究表明,在仍使异噻唑啉类似物脱氨的同时,偏爱天然底物。
