have been synthesized which are structurally related to the natural antiviral antitumor antibiotics netropsin and distamycin bearing two such moieties linked by polymethylene bridges. Cytostatic activity against both human and murine tumor cell lines and their in vitro activity against a range of viruses are reported. Enhanced antiviral activity was obtained against vaccinia virus. As a result of the
合成了一组寡肽,其在结构上与天然抗病毒抗肿瘤抗生素netropsin和distamycin有关,带有通过聚亚甲基桥连接的两个这样的部分。据报道,对人和鼠肿瘤细胞系均具有细胞抑制活性,并且它们对多种病毒具有体外活性。获得了针对牛痘病毒的增强的抗病毒活性。由于引入了多亚甲基接头[(CH2)n,n = 1、2和6-8],与母体化合物netropsin和distamycin相比,其抗肿瘤和抗痘苗病毒的活性均显着增强。讨论了这些试剂的生物学活性,既涉及其结构差异,也涉及其与双链DNA的小沟结合。
