small molecules that bind to CTG trinucleotide repeats in DNA. 1H-Pyrrolo[3,2-h]quinoline-8-amine (PQA) has a tricyclic aromatic system with unique non-linear hydrogen-bonding surface complementary to thymine. We have synthesized a series of PQA derivatives with different alkylamino linkers. These PQAs showed binding to pyrimidine bulge DNAs and CNG (N = T and C) repeats depending on the linker structure
我们描述了一种新的分子设计,合成以及与DNA中CTG三核苷酸重复序列结合的小分子的研究。1 H-吡咯并[3,2- h ]喹啉-8-胺(PQA)具有三环芳族体系,其独特的非线性氢键表面与胸腺嘧啶互补。我们合成了一系列具有不同烷基氨基接头的PQA衍生物。这些PQA显示与嘧啶凸出的DNA结合,并且CNG(N = T和C)重复序列取决于接头结构,而缺少吡咯环的喹啉衍生物显示出更低的结合亲和力。PQA是CTG和CCG重复结合的有用分子单元。
