report the synthesis of hitherto unknown 5-haloethynyl and 5-(1,2-dihalo)vinyluracil nucleoside analogues of the anti-HIV AZT, and FLT drugs. The key step of those syntheses is a Pd(0) cross-coupling at C5 position under Sonogashira conditions. Finally, based on their in vitro anti-HIV activities and their cytotoxicity on PBM, CEM, and VERO cell lines, the best compounds were the 2′,3′-dideoxy-3′-fluor
在本文中,我们报告了迄今为止未知的 5-卤乙炔基和 5-(1,2-二卤) 乙烯基尿嘧啶核苷类似物的抗 HIV AZT 和 FLT 药物的合成。这些合成的关键步骤是在 Sonogashira 条件下 C5 位置的 Pd(0) 交叉偶联。最后,根据其体外抗 HIV 活性及其对 PBM、CEM 和 VERO 细胞系的细胞毒性,最好的化合物是 2',3'-dideoxy-3'-fluoro-5-(bromo-2-iodo )乙烯尿苷(10b,EC 50为 0.6 μM)和 3'-azido-2',3'-dideoxy-5-(bromo-2-iodo)vinyluridine ( 16b , EC 50为 1.1 μM)。
