Abstract
Mixed backbone oligonucleotides (MBOs) which contain segments of prima ry phosphoramidate linkages (PO-NH2) in conjunction,with either phosph oric diesters (PO), or phosphorothioates (PS) were prepared. Thermal d enaturation of the duplexes with RNA and DNA reveal that they form sta ble duplexes which display cooperative melting profiles. Preliminary s tability studies reveal that the PO-NH2 linkage is resistant to serum nucleases. Thus, these MBOs represent novel antisense molecules. Copyr ight (C) 1996 Elsevier Science Ltd
