Flavonoids exhibit essential but limited biological properties which can be enhanced through chemical modifications. In this study, we designed, synthesized, and characterized two novel flavonoid derivatives, quercetin penta-acetamide (1S3) and apigenin tri-acetamide (2S3). These compounds were confirmed using (1H, 13C) NMR, UV-Vis, and FT-IR characterizations. Their interaction with fish sperm DNA
类黄酮表现出重要但有限的生物特性,可以通过化学修饰来增强。在本研究中,我们设计、合成并表征了两种新型黄酮类衍生物:槲皮素五乙酰胺(1S3)和芹菜素三乙酰胺(2S3)。这些化合物使用 ( 1 H, 13 C) NMR、UV-Vis 和 FT-IR 表征进行了确认。通过紫外-可见光和荧光分光光度法研究了它们在生理 pH 下与鱼精子 DNA (FS-DNA) 的相互作用。发现UV-Vis实验的结合常数( K b )对于1S3为1.43±0.3×10 4 M -1 ,对于2S3为2.08±0.2×10 4 M -1 。1S3和2S3的荧光猝灭实验的结合常数( K SV )分别为1.83×10 4 M -1和1.96×10 4 M -1。基于分子建模和对接研究,发现1S3和2S3的结合亲和力分别为-7.9和-9.1 kcal mol -1 。化合物-DNA对接模型与我们的实验结果相关,它们是凹槽结合
