Synthesis and binding study of phosphonate analogues of PNAs and their hybrids with PNAs

Article abstract of DOI:10.1080/07328319808004700

The preparation of monomers for the synthesis of phosphonate analogues of peptide nucleic acids containing the four natural nucleobases: thymine, cytosine, adenine and guanine, has been accomplished. The monomers obtained were used for the automated online solid phase synthesis of pure phosphono- PNA oligomers as well as chimeras consisting of phosphono-PNA and PNA resudies. The hybridization properties of these oligonucleotide mimics to complementary DNA and RNA fragments were studied.
