摘要:
Modified oligonucleotides which possess at least one substituted 7-deazapurine base form more stable hybridization complexes with nucleic acids than unsubstituted analogs. They are useful as inhibitors of gene expression, as probes for detecting nucleic acids, as aids in molecular biology and as pharmaceuticals or diagnostic agents. Processes for preparing them are provided.
