Treatment of 5-(methylamino)-1-β-D-ribofuranosylimidazole-4-carboxamide (3) with CNBr followed by cyclization and reaction with bromoacetone gave 3-β-D-ribofuranosylwye (2) whose glycosidicbond was cleaved rapidly in acidic or alkaline solution, but was fairly stable at pH 5–8·5 at 37 °C.

Oligomer compositions comprising first and second oligomers are provided wherein at least a portion of the first oligomer is capable of hybridizing with at least a portion of the second oligomer, at least a portion of the first oligomer is complementary to and capble of hybridizing to a selected target nucleic acid, and at least one of the first or second oligomers has a modified base for binding to an adenine or guanine base in the opposite strand. Oligonucleotide/protein compositions are also provided comprising an oligomer complementary to and capable of hybridizing to a selected target nucleic acid and at least one protein comprising at least a portion of an RNA-induced silencing complex (RISC), wherein the oligomer has a modified base for binding to an adenine or guanine base in the opposite strand.
