nonhydrolyzable purine diphosphate mimic was synthesized. A modular synthetic protocol was developed, utilizing 2-amino-6-(methylthio)-4-(trimethylsilyl)nicotinonitrile as the key synthon in the preparation of highly substituted 2-aminonicotinonitriles. These building blocks were subsequently elaborated to the pyrido[2,3-d]pyrimidine bisphosphonates (PYPY-BPs). Biochemical screening identified analogs of PYPY-BPs
双膦酸盐可以模拟核苷酸转移反应中的焦磷酸盐离去基团,并有效抑制RNA / DNA聚合酶。在寻找HIV-1逆转录酶(RT)抑制剂的过程中,合成了一种新的非水解性嘌呤二磷酸嘌呤模拟物的化学型。利用2-氨基-6-(甲硫基)-4-(三甲基甲硅烷基)烟腈作为制备高度取代的2-氨基烟腈的关键合成子,开发了一种模块化的合成方案。这些构件随后被修饰为吡啶并[2,3- d ]嘧啶双膦酸酯(PYPY-BPs)。生化筛选鉴定出可抑制HIV-1 RT催化的DNA合成的PYPY-BPs类似物。
