标 题:Derivatives of nucleosides which may be used for the synthesis of marked oligonucleotides, and oligonucleotides obtained from these derivatives and their synthesis
摘要:A nucleoside derivative which may be used for the synthesis of oligonucleotides of the formula (I), in which: R1 represents a hydrogen atom or an unstable radical in an acid medium suitable for nucleotide synthesis; R2 represents a hydrogen atom or a protective radical, a functional radical or a support which may be used for nucleotide synthesis; R3 represents a hydrogen atom, the hydroxyl radical or a protected hydroxyl radical; and B represents a radical derived from a puric or pyrimidic base comprising an exocyclic NH2 group substituted by an R4Z group where R4 represents a single bond or a hydrocarbonated radical and Z is a marker element.

标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.
