  Synthesis of Peptide Nucleic Acid Monomers Containing the Four Natural Nucleobases: Thymine, Cytosine, Adenine, and Guanine and Their Oligomerization

  摘要：

  The preparation of mixed-sequence PNAs (PNAs containing the four natural nucleobases; thymine, cytosine, adenine, and guanine) is described. The PNA monomers containing thymine, Cbz-protected cytosine, or adenine or benzyl-protected guanine were prepared via convergent syntheses. Subsequent to introduction of the carboxymethyl linker at N-1 of the pyrimidines or N-9 of the purines and suitable protection of exocyclic groups, the nucleobase derivatives were coupled to the Boc-protected backbone esters 10a or 10b and finally hydrolyzed affording the monomers 12a-d. The exocyclic amino groups of cytosine and adenine were protected with a benzyloxycarbonyl group. The exocyclic amino group of guanine was left unprotected whereas O-6 was protected as the benzyl ether. Two mixed-sequence 10-mers, each with five purines incorporated, and a mixed-sequence 15-mer Containing seven purines were assembled essentially following standard solid phase peptide synthesis protocols.

  produced and report herein a diverse library of 181 purine, pyrimidine, and 1,2,4-triazole-N-acetamide analogues which were prepared in a parallel high throughput solution-phase reaction format. A set of assorted amines were reacted with several nucleic acid N-acetic acids utilizing HATU as the coupling reagent to produce diverse acyclic nucleoside N-acetamide analogues. These reactions were performed

  使用高通量筛选技术，分子多样性在针对表型或基于酶的靶标的现代药物发现中起着关键作用。在美国国立卫生研究院路线图计划的试点图书馆计划的主持下，我们生产并报告了181种嘌呤，嘧啶和1,2,4-三唑-N-乙酰胺类似物的多样化文库，它们以平行的高通量制备溶液相反应形式。利用HATU作为偶联剂，将一组各种胺与几种核酸N-乙酸反应，以产生多种无环核苷N-乙酰胺类似物。这些反应是在惰性气氛下使用24孔反应块和自动试剂分配平台进行的。使用自动装载固体样品的预装柱和预装硅胶柱，在自动纯化系统上纯化目标化合物。所有化合物均通过NMR和HRMS进行表征，并通过HPLC分析纯度，然后提交至NIH的分子库小分子储存库（MLSMR）。通过分子图书馆探针生产中心网络（MLPCN）程序进行的初步筛选表明，几种类似物均表现出多样而有趣的生物学活性。

  molecule constituted by (i) a hexameric PNA moiety complementary to six among the nine residues of the dimerization initiation site loop of HIV-1 and (ii) a spacer tethering the N- to the C-extremities of the PNA, has been elaborated to inhibit the dimerization process of HIV-1 genome. This compound has been synthesized following a liquid-phase procedure (fully protected backbone approach). Preliminary
