Av. Shipitsyn et al., Synthesis of [bis(inosine-5 ')]-tetraphosphate and [bis(inosine-5 ')]-pentaphosphate analogue bearing the residues of methylenediphosphonic acid, NUCLEOS NUC, 19(5-6), 2000, pp. 881-889
Various methods of synthesis of metabolically stable phosphonate analogues
of bisnucleoside oligophosphates containing two residues of methylenediphos
phonic acid in the oligophosphate chain are studied. Phosphonate analogues
of Ip(4)I and Ip(5)I are prepared.
