A number of novel phosphinate and phosphate triester derivatives of the anti-viral nucleoside analogue araA have been prepared. Spectroscopic and analytical data have been collected on both the reagents and the nucleotides. An in vitro assay indicated inhibition of DNA synthesis by mammalian cells, by each of the nucleotide derivatives, in the range 3-30 microM. Inhibition was reduced, but not abolished, for the phosphinates relative to the phosphates. These results are consistent with a mode of action involving release of the free nucleoside araA and the nucleotide araAMP.
已经制备了抗病毒核苷类似物阿糖腺苷(araA)的多种新型次膦酸酯和磷酸三酯衍生物。已收集了试剂和核苷酸的光谱及分析数据。体外试验表明,每种核苷酸衍生物在3 - 30微摩尔范围内均可抑制哺乳动物细胞的DNA合成。相对于磷酸盐,次膦酸酯的抑制作用有所降低,但并未消除。这些结果与涉及游离核苷阿糖腺苷和核苷酸阿糖腺苷一磷酸(araAMP)释放的作用模式一致。
