fluorenylidene allene oxides were generated photochemically from appropriately substituted fluorenol derivatives in 2,2,2-trifluoroethanol (TFE) in order to assess the affect of steric bulk on the absolute reactivity of the allene oxides. The absolute reactivities of the allene oxides were measured using nanosecond laser flash photolysis, and were found to change little in TFE upon going from α-methyl to

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.
Chemical agents, such as derivatives of hydroxy benzene moieties, and similar heterocyclic ring structures, including salts thereof, that act as anti-cancer and anti-tumor agents, especially where such agents modulate the activity of enzymes and structural polypeptides present in cells, such as cancer cells, or where the agents modulate levels of gene expression in cellular systems, including cancer cells, are disclosed, along with methods for preparing such agents, as well as pharmaceutical compositions containing such agents as active ingredients and methods of using these as therapeutic agents.
Oligonucleotide analogues conjugated to carrier peptides are provided. The disclosed compounds are useful for the treatment of various diseases, for example diseases where inhibition of protein expression or correction of aberrant mRNA splice products produces beneficial therapeutic effects.
