saturated heterocyclic analogues of distamycin were prepared and examined. A fluorescent intercalator displacement (FID) assay conducted on p[dA]-p[dT] DNA to obtain C(50) values and a hairpin deoxyoligonucleotide containing an A/T-rich binding site was used to evaluate DNA binding affinity. It is observed that saturated heterocycles greatly reduce the DNA binding relative to distamycin.
制备并检查了一系列的他霉素的饱和杂环类似物。对p [dA] -p [dT] DNA进行荧光嵌入剂置换(FID)分析以获得C(50)值,并使用含有富含A / T的结合位点的发夹脱氧寡核苷酸来评估DNA结合亲和力。观察到饱和杂环大大降低了相对于双霉素的DNA结合。
