Two routes to the naturally occuring DNA-binding antitumor antibiotic DC-81 are described, one of which involves a novel cyclization process based on acid resin. The second route involves the synthesis of a new compound, 6-nitrovanillic acid, a key A-ring component of many naturally occuring PBDs. These routes have provided a sufficient quantity of DC-81 to allow complete characterization and evaluation
描述了两种天然结合DNA的抗肿瘤抗生素DC-81的途径,其中一种涉及基于酸性树脂的新型环化过程。第二种途径涉及新化合物6-硝基香草酸的合成,6-硝基香草酸是许多天然存在的PBD的关键A环成分。这些途径提供了足够量的DC-81,可以在DNA结合和体外细胞毒性研究中进行完整的表征和评估。
