Functionally-modified oligonucleotide analogues comprising modified intersubunit linkages and/or modified 3′ and/or 5′-end groups are provided. The disclosed compounds are useful for the treatment of diseases where inhibition of protein expression or correction of aberrant mRNA splice products produces beneficial therapeutic effects.
Sulfur and nitrogen half-mustard compounds lose their aggressive properties when the chlorine atom is replaced by a carbonate moiety. The anchimeric effect of the novel mustardcarbonateanalogues is investigated. The reaction follows first-order kinetics, does not need any base, and occurs with –OH, –NH and acidic –CH nucleophiles. Most of these molecules are unexplored and might provide a novel strategy

The cationic 16e complexes [RuCp*(η 2 (N,N)-Me 2 NCH 2 CH 2 N(CH 2 CHMe 2 ) 2 )] + ( 1 ) and [RuCp*(η 2 (N,N)-Me 2 NCH 2 CH 2 H 2 ] + ( 2 ) as well as the 18e complex [RuCp*(η 6 -C 6 H5 -N(Me)NCH 2 CH 2 NMe 2 )] + ( 3 ) have been synthesized as the BAr′ 4 (Ar′=3,5-C 6 H 3 (CF 3 ) 2 ) salts in one-pot reactions starting from [RuCp*(Cl)] 4 . For 1 , the X-ray crystal structure has also been determined
