ligands (DB3P(n); n = 1,2,3,4) was synthesized and their spectral, biological and virological properties were investigated. With a methylene spacers of different lengths blocks of three AT pairs located at different distances from each other could be recognized. The compounds synthesized suppressed the activity of HIV-1 integrase at submicromolar concentrations (0.25–0.50 µМ). Also, DB3P(n) were found
合成了一系列新的 AT 特异性小沟 DNA 配体 (DB 3 P( n );n = 1,2,3,4),并研究了它们的光谱、生物学和病毒学特性。使用不同长度的亚甲基间隔区,可以识别位于彼此不同距离处的三个 AT 对块。合成的化合物在亚微摩尔浓度 (0.25–0.50 µМ) 下抑制了 HIV-1 整合酶的活性。此外,DB 3 P( n ) 被发现是 I 型单纯形病毒和 DNA 拓扑异构酶 I 的有效抑制剂。合成的 DB 3 P( n) 在水中表现出良好的溶解性,可以穿透细胞和核膜,并对活细胞中的 DNA 进行染色。 图形概要
