The present invention is directed to the means by which to alter the binding affinity and/or specificity of a compound with a sequence of DNA in the minor groove of a double-strand thereof. More particularly, the present invention is directed to a synthetic and/or non-naturally occurring compound (e.g., an analog of a polyamide oligomer or polymer) which contains at least one hydrogen bond donor moiety and at least one hydrogen bond acceptor moiety, wherein the latter moiety or “building block” has a fused, bicyclic structure which is heteroaromatic, said structure having a heteroatom therein which acts as a hydrogen bond acceptor to bind guanine in the minor groove of the dsDNA sequence, and which is incapable of forming a tautomer. In one particular embodiment of the synthetic and/or non-naturally occurring compound, the fused, bicyclic structure occupies an initial or first terminal position within the compound.
本发明涉及一种改变化合物与DNA双链中小沟的序列的结合亲和力和/或特异性的方法。特别地,本发明涉及一种合成和/或非自然存在的化合物(例如,聚酰胺寡聚物或聚合物的类似物),该化合物含有至少一个氢键供体基团和至少一个氢键受体基团,其中后者基团或“构建块”具有融合的、杂环芳香性的双环结构,该结构在其中具有作为氢键受体以结合双链DNA序列中的鸟嘌呤的杂原子,并且不能形成互变异构体。在合成和/或非自然存在的化合物的一个特定实施例中,融合的、双环结构占据化合物的初始或第一端位置。
