bis-amidates in excellent yields (83–98%) and purity. The methodology has been applied to the synthesis of the potent anticancer agent GS-9219, and symmetrical bis-amidates of other biologically active phosphonic acids. Anti-HIV, antiproliferative, and immunomodulatory activities of the compounds are discussed including the bis-amidate prodrugs 14 and 17 that exhibited anti-HIV activity at submicromolar
报道了一种从游离膦酸或膦酸酯二酯开始一锅合成无环核苷膦酸酯的二酰胺(双酰胺)前体药物的新颖有效的方法。膦酸酯二酯通过其双(三甲基甲硅烷基)酯的方法非常方便,消除了膦酸的分离和繁琐的纯化,并以极佳的收率(83-98%)和纯度提供了相应的双氨基酸酯。该方法已应用于有效的抗癌药GS-9219以及其他具有生物活性的膦酸的对称双氨基酸盐的合成。讨论了该化合物的抗HIV,抗增殖和免疫调节活性,包括双氨基酸盐前药14和17 在亚微摩尔浓度下表现出抗HIV活性,且细胞毒性最小。
