D. Rejman et al., Oligonucleotides with isopolar phosphonate internucleotide linkage: A new perspective for antisense compounds?, NUCLEOS NUC, 20(4-7), 2001, pp. 819-823
Several types of isopolar modified oligothymidylates and oligoadenylates (1
5 mers) with the phosphonate -O-P-CH2-O- internucleotide linkage were prepa
red. The modified oligonucleotides were subjected to the study of their hyb
ridization properties, resistance against nucleases, and the ability to eli
cit RNase H activity.
