The present disclosure describes bis-modified bicyclic nucleosides and oligomeric compounds that can be prepared comprising at least one of these bis-modified bicyclic nucleosides. More particularly, the bis-modified bicyclic nucleosides have at least one substituent group at the 5′-methylene and on the bridge methylene and can be chiral. These bis-modified bicyclic nucleosides are expected to be useful for enhancing one or more property of oligomeric compounds including for example enhancing nuclease resistance.

The present invention provides a reactive diluent composition which overcomes drawbacks of both the radical-cure and the cationic-cure reactive diluents and can be applied in a broad variety of uses such as paints, inks, adhesives, pressure sensitive adhesives, surface-modifiers, and molding materials; a curable resin composition containing the same; an activated energy ray-curable resin composition; and an activated energy ray-curable ink composition for ink-jet printing.A reactive diluent composition comprisinga vinyl ether group-containing (meth)acrylic ester represented by the following general formula (1):wherein R<1 >represents a hydrogen atom or a methyl group; R<2 >represents an organic residue of 2 to 20 carbon atoms; R<3 >represents a hydrogen atom or an organic residue of 1 to 11 carbon atoms anda hydroxyl group-containing polymerizable compound and / or divinyl ether.

This invention provides novel liver targeting agents and their synthetic methods. A liver targeting agent, with a lysine based nitrilotriacetic acid structure as backbone which acquires multivalency with saccharide groups, to bind with a galactosamine chain or lactose chain is disclosed. In particular, only one amino acid L-lysine is involved to provide trivalency. All carboxyl groups in Nε-benzyloxycarbonyl-Nα-dicarboxymethyl-L-lysine can be conjugated with three glycosides of ahGalNAc or ahLac in one step. This invention also provides a hexa-lactoside. In particular, the TFA-AHA-Asp was used to conjugate 2 molecules of NTA(ahLac)3. This invention also provides a method for adding a spacer between NTA and DTPA. The extended hepatocyte-specific glyco-ligand has higher 111In-radiolabelling yield than those non-extended.
