  Synthesis of cyclic di-nucleotidic acids as potential inhibitors targeting diguanylate cyclase

  摘要：

  Five analogs of cyclic di-nucleotidic acid including c-di-GMP were synthesized and evaluated for their biological activities on Slr1143, a diguanylate cyclase of Synechocystis sp. Slr1143 was overexpressed from the recombinant plasmid which contained the gene of interest and subsequently purified by affinity chromatography. A new HPLC method capable of separating the compound and product peaks with good resolution was optimized and applied to the analysis of the compounds. Results obtained show that cyclic di-inosinylic acid 1b demonstrates a stronger inhibition on Slr1143 than c-di-GMP and is a potential inhibitor for biofilm formation. (c) 2010 Elsevier Ltd.

• Synthesis of Oligoinosinates with 2′–5′ Internucleotide Linkage in Aqueous Solution Using Pb²⁺Ion
  作者：Hiroaki Sawai、Masaji Ohno

  DOI：10.1246/bcsj.54.2759

  日期：1981.9

  the polymerization of inosine-5′-phosphorimidazolide in aqueous solution using Pb2+ ion. 2′–5′ Internucleotide linkage was preferentially formed. The yields of the 2′–5′ linked dimer, trimer, and tetramer were 14.8, 4.5, and 1.6%, respectively. A small amount of linkage isomers of oligoinosinates with 3′–5′ linkage was obtained. The products were characterized by sequential enzyme tests.
