A novel family of acyclic nucleoside phosphonates (ANPs) bearing a (1H-1,2,3-triazol-4-yl)phosphonic acid group in the acyclic side chain have been prepared in order to study the influence of the hetaryl rigidizing element on the biological properties of such compounds. The key synthetic step consisted of a copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) between diethyl ethynylphosphonate and
为了研究杂芳基刚性化元素的影响,制备了一个新的无环侧链上带有(1 H -1,2,3-三唑-4-基)膦酸基团的无环核苷膦酸酯(ANP)家族。这类化合物的生物学特性。关键的合成步骤包括乙二炔基膦酸二乙酯与相应的叠氮烷基前体之间的铜(I)催化的叠氮化物-炔烃环加成反应(CuAAC)。该家族中的两个带有鸟嘌呤碱基的ANP,无论在C-2'原子上的立体化学如何,都对人6-氧嘌呤磷酸核糖基转移酶具有最高的效力。四种化合物抑制恶性疟原虫6-氧嘌呤磷酸核糖基转移酶的K i差异很小不论碱基是鸟嘌呤,次黄嘌呤还是黄嘌呤,该值均抑制Pv HGPRT ,只有两个以鸟嘌呤为碱基。
