Patent ID: 7951926

Claim:
Molecules of formula (XIII): wherein X is selected from N, O, S, an alcane di-yl comprising 1 to 12 carbon atoms; preferentially X is selected from N, O; m is an integer, m≧1 L is a linker which may be selected from the following list: alcane poly-yl functions with 1 to 12 carbon atoms, linear branched or cyclic possibly interrupted by one or several oxygen (—O—), nitrogen (—NH—, —N═) or sulphur (—S—) bridges or phosphodiester [—O—(O − )P(═O)—O—] bridges; x is an integer, 30≧x≧1; x′ is an integer, 30≧x′≧1; D is a linker between X and the carbon in position 4 of the triazole ring; D′ is a linker between L and the carbon in position 4 of the triazole ring; y is 0, 1 or 2; z and z′ are integers, z and z′≧0, at least one of z and z′ is ≧1; B is selected from H, a solid support or a tag; the oligonucleotide is substituted either on its 3′-extremity, on its 5′-extremity or inside of the sequence; R is a molecule of interest.
