2'-Deoxypseudoisoguanosine CEP


2'-Deoxypseudoisoguanosine (Pseudoiso-dG) is related to Iso-dG by transposition of the nitrogen atom at position 3 and the carbonyl group at position 2 of the nucleobase. It is also related to 2'-Deoxypseudoguanosine (Pseudo-dG) by transposition of the C-NH2 group at position 3 and the carbonyl group at position 6.  Pseudoiso-dG CEP is a phosphoramidite that may be useful for incorporation into nucleic acids, where it may provide a novel alternate base-pairing scheme.


The transposition of atoms or groups in the purine nucleobase of G/dG provides isomers that have altered base-pairing capabilities.  We offer a family of guanosine isomers in nucleoside and phosphoramidite forms.

Pseudoiso-dG CEP (BA 0314) may be used to incorporate Pseudoiso-dG nucleotides into DNA. It is based on the nucleoside 2'-Deoxypseudoisoguanosine (Pseudoiso-dG, originally synthesized by Hosmane and co-workers1), which is also available (PRA 10104).

Pseudoiso-dG CEP and Pseudoiso-dG are part of a family that includes Guanosine (PR 3703), 2'-Deoxyguanosine (PR 3452), the isomeric nucleosides Isoguanosine (Iso-G, PR 3735), 2'-Deoxyisoguanosine (Iso-dG, PR 3465), 2'-Deoxypseudoguanosine (Pseudo-dG, PRA 10103), and the phosphoramidite Pseudo-dG CEP (BA 0312) .
