摘要: An oligonucleotide analogue having 10 to 200 natural and/or synthetic nucleoside units, linked by internucleoside linkages, at least one of the internucleoside linkages being of formula (I), where the indicated methylene group is attached to a 3' carbon atom of a nucleoside, the indicated oxygen atom is attached to a 5' carbon atom of an adjacent nucleoside, R1 is hydrogen, hydroxy, O-, thiol, S-, -NH2 or a group of formula R1a, -OR1a, -SR1a, -NHR1b or -NR1bR1c where R1a is an unsubstituted or substituted C1 to C10 alkyl, C2 to C10 alkenyl, C3 to C8 cycloalkyl, C6 to C10 aryl or C7 to C13 aralkyl group and R1b and R1c are each independently an unsubstituted or substituted C1 to C10 alkyl, C2 to C10 alkenyl, C3 to C8 cycloalkyl, C6 to C10 aryl or C7 to C13 aralkyl group or R1b and R1c together with the nitrogen atom to which they are attached denote a five- or six-membered heterocyclic ring, and X is oxygen or sulphur.
