antiviral, anticancer, and other biological activities. However, their direct interactions at target binding sites are not well understood. A new class of 2′-deoxy-2′-fluoro-C6-substituted uridine and UMP derivatives were synthesized and evaluated as inhibitors of orotidine 5′-monophosphate decarboxylase (ODCase or OMPDCase). These compounds were synthesized from the key intermediate, fully protected 2′-de
氟化核苷和核苷酸因其抗病毒、抗癌和其他生物活性而引起药物化学家的极大兴趣。然而,它们在目标结合位点的直接相互作用尚不清楚。合成了一类新的 2'-脱氧-2'-氟-C6-取代的尿苷和 UMP 衍生物,并将其作为乳清酸 5'-单磷酸脱羧酶(ODCase 或 OMPDCase)的抑制剂进行评估。这些化合物是由关键中间体、完全保护的 2'-脱氧-2'-氟尿苷合成的。在合成的化合物中,2'-deoxy-2'-fluoro-6-iodo-UMP 以 0.62 ± 0.02 M -1 s -1的二级速率常数共价抑制人 ODCase. 有趣的是,6-cyano-2'-fluoro 衍生物与 ODCase 共价相互作用,打破了传统思维,其核糖基衍生物通过 ODCase 转化为 BMP。这证实了 2'-氟部分影响核苷酸 C6 位置的化学反应,从而影响 ODCase 活性位点的相互作用。将 2'-氟化核苷酸的分子相互作用与
