title: Incorporation of positively charged ribonucleic guanidine linkages into oligodeoxyribonucleotides: Development of potent antisense agents.
abstract: Oligodeoxynucleic acid (21-mer) containing both negatively charged phosphate and positively charged ribonucleic guanidine linkages (RNG/DNA chimera) have been synthesized. DNA binding characteristics and nuclease resistance of RNG/DNA chimeras have been evaluated. Using the bcr-abl oncogene (cause of chronic myeloid leukemia) as a target, the binding of a 21-mer RNG/DNA chimera that includes six RNG's is more than 103.5 stronger than the binding of 21-mer composed solely of DNA.
