Title
(EN) FORMATION OF TRIPLE HELIX COMPLEXES OF DOUBLE STRANDED DNA USING NUCLEOSIDE OLIGOMERS WHICH COMPRISE PURINE BASE ANALOGS
(FR) FORMATION DE COMPLEXES A TRIPLE HELICE D'ADN DOUBLE BRIN A L'AIDE D'OLIGOMERES DE NUCLEOSIDES QUI COMPRENNENT DES ANALOGUES A BASE DE PURINE
Abstract
(EN)
A specific segment of double stranded DNA may be detected or recognized by formation of a triple helix structure using an oligomer comprised of nucleosidyl units linked by internucleosidyl phosphorus linkages. Function or expression of double stranded DNA segments may be prevented by triple helix formation. Novel oligomers comprising modified nucleosidyl units are useful in triple helix formation, and may be optionally derivatized with DNA modifying groups.
(FR)
Un segment spécifique d'ADN double brin peut être détecté ou reconnu par formation d'une structure à triple hélice en utilisant un oligomère constitué d'unités nucléosides reliées par des liaisons de phosphore internucléoside. La fonction ou l'expression de segments d'ADN double brin peut être empêchée par la formation à triple hélice. De nouveaux oligomères comprenant des unités nucléosides modifiées sont utiles dans la formation à triple hélice et peuvent éventuellement être dérivés avec des groupe de modification de l'ADN.
