  Synthesis and Biological Evaluation of Some Acyclic Pyridine C-Nucleosides. Part Two

  摘要：

  3-Bromo-5-(2-hydroxyethylthiomethyl)pyridine ((7) under bar) was synthesized by reaction of 3-bromo-5-chloromethylpyridine hydrochloride ((6) under bar) with the mono sodium salt of 2-mercaptoethanol. 3-Bromo-5-hydroxymethylpyridine (<(10)under bar>) was, after protection as a silyl ether, converted to the 3-carboxy analogue using BuLi and CO2. After deprotection with NH4F, the alcohol function was chlorinated using SOCl2. Finally, attachment of the acyclic chain and ammonolysis gave the acyclic nicotinamide nucleosides. Treatment of the latter compounds with Lawesson's reagent gave the thioamide analogues. All compounds were identified by NMR and DCI-MS. The acyclic pyridine C-nucleosides were evaluated against a series of tumor-cell lines and a variety of viruses. No marked biological activity was found.

  The synthesis of phosphonomethoxy derivatives of some acyclic pyridine-C-nucleosides is described. Reaction of the acyclic nucleoside alkoxides with diethyl (tosyloxymethyl)phosphonate (5) led to the protected phosphonate derivatives. After eventual modification of the pyridine moiety, the ethyl protecting groups could be removed by treatment with bromotrimethylsilane. The phosphonates were evaluated against a series of tumor cell lines and a variety of viruses. Compared to the nucleoside analogues, they showed a slightly higher activity.
