F. Raynaud et al., SYNTHESIS AND CHARACTERIZATION OF O-6-MODIFIED DEOXYGUANOSINE-CONTAINING OLIGODEOXYRIBONUCLEOTIDES FOR TRIPLE-HELIX FORMATION, Tetrahedron, 52(6), 1996, pp. 2047-2064
Two new modified deoxyguanosine derivatives linked through their C-6 p
osition to a psoralen and an acridine derivative have been synthesized
and incorporated into oligonucleotide chains. Difficulties observed d
ining the purification of oligonucleotides containing a stretch of G a
nd one method used to solve this problem are discussed.
