Inorganic pyrophosphate (PPi) is the product of the polymerization reaction catalyzed by DNA- and RNA-polymerases. A number of novel non-hydrolsable PPi analogues was synthesized; some of them inhibited the polymerization reaction catalyzed by hepatitisCvirusRNA-dependentRNA-polymerase (NS5B). A new pharmacophore based on a non-hydrolysable methylenediphosphonate backbone has been developed. The
无机焦磷酸盐 (PPi) 是由 DNA 和 RNA 聚合酶催化的聚合反应产物。合成了许多新型的不可水解的 PPi 类似物;其中一些抑制了丙型肝炎病毒 RNA 依赖性 RNA 聚合酶 (NS5B) 催化的聚合反应。已开发出基于不可水解的亚甲基二膦酸酯骨架的新药效团。介绍了 12 种双膦酸盐的构效关系分析,并说明了对 NS5B 聚合酶活性抑制至关重要的结构特征。

neuromodulator that influences various functions of the central nervous system. It possesses anticonvulsant and neuroprotective properties [1, 2]. At the same time adenosine modification reveals new properties of the nucleoside. Recently, a series of N6,5'-bisureidoadenosines with a broad spectrum of antiproliferative activity have been obtained [3]. Adenosine salt of aspartic acid is known to exhibit antifibrotic

The convenient methods for the synthesis of new trimethylsilyl esters of aminomethylenediphosphonic acids are elaborated. The new substituted N-formylaminomethylenediphosphonates are obtained via the interaction of trimethylsilyl esters of methylenediphosphonic acids with a mixture of triethyl orthoformate and ethanol. Also boron trifluoride–diethyl etherate as an effective catalyst is used for the

Valuable and highly water soluble N-phosphono methylene mono- and di-amino alkane mono- and polyphosphonic acids which have not only an >N--CH.sub.2 --PO.sub.3 H.sub.2 group but also a C--PO.sub.3 H.sub.2 group in their molecule are produced by reacting amino alkane mono- or diphosphonic acids with formaldehyde and phosphorous acid or alkane nitriles with phosphorous acid, formaldehyde, and concentrated hydrochloric acid. The resulting phosphonic acid compounds are valuable sequestering agents forming complex compounds with bi- and polyvalent metal ions. They are useful for water softening even in substoichiometric amounts, in textile treatment baths, in the paper manufacture, in tanning baths, for the manufacture of liquid fertilizers, and for other purposes.
