  4. 3'-Cholesterol SynBase™ CPG 1000/110
  5. View Product Details >

    The introduction of hydrophobic residues into oligonucleotides with a view to improving their penetration into cells is an idea that has recently met with some success. Cholesteryl-conjugated oligonucleotides have in particular been the subject of substantial interest in antisense and other studies due to the lipophilicity and ready availability of cholesterol.

    Historically this has been done by post-synthetic conjugation of an amino-modified oligo to cholesterol chloroformate, however direct attachment during synthesis is much more convenient. For 3'-modification we offer 3'-Cholesterol SynBase™ CPG 1000/110. This product has a couple of notable advantages over existing products. It is not susceptible to 1,2-diol elimination as observed in some other supports. The product can also be used without IP restriction.

    For 5'-modification see Cholesterol Phosphoramidite.

  6. 5'-Tocopherol-CE Phosphoramidite
  7. View Product Details > An extension to our line of hydrophobic modifiers, based on Vitamin E. This is used to introduce tocopherol at the 5'-end of the oligo, either directly on the 5'-OH of the final base or in conjunction with a spacer or linker such as spacer 18 or C6 S-S thiol. The latter will enable the tocopherol to be cleaved via the disulphide bridge, for example once the oligo has been delivered to the cell. To include a C8 spacer natively use 5'-Octyl-tocopherol.

This is used to introduce tocopherol at the 5'-end of the oligo directly on the 5'-OH with a C8 spacer natively included. Incorporation of thiol C6 S-S will also enable the tocopherol to be cleaved via the disulphide bridge, for example once the oligo has been delivered to the cell. To omit the C8 spacer use 5'-Tocopherol.

    The introduction of hydrophobic residues into oligonucleotides with a view to improving their penetration into cells is an idea that has recently met with some success. Cholesteryl-conjugated oligonucleotides have in particular been the subject of substantial interest in antisense and other studies due to the lipophilicity and ready availability of cholesterol.

    Historically this has been done by post-synthetic conjugation of an amino-modified oligo to cholesterol chloroformate, however direct attachment during synthesis is much more convenient. For this purpose, therefore, we offer 3'-Cholesterol SynBase™ CPG 1000/110(2394).

    Of similar application, but comparatively less studied to date, is the incorporation of the palmitoyl moiety into oligonucletides. Recently, researchers synthesised an oligonucleotide conjugate with a 5'-terminal palmitoyl group attached through an amide bond. This has been used to modify GRN163, a thio-phosphoramidate oligonucleotide, to enhance the potency of telomerase inhibition.

    Using similar synthetic methodology to that of 2394, we have prepared 3'-Palmitate SynBase™ CPG 1000/110 for direct incorporation of a palmitoyl group during oligo synthesis.
