Abstract
Sequence-tag-guided screening of soil environmental DNA libraries can be used to guide the discovery of new compounds with improved properties. In heterologous expression experiments the eDNA-derived arm cluster encodes arimetamycin A, an anthracycline that is more potent than clinically used natural anthracyclines and retains activity against multidrug-resistant (MDR) cancer cells.
摘要
序列标签引导的土壤环境 DNA 文库筛选可用于指导新化合物的发现，改善其性质。在异源表达实验中，eDNA 衍生的 arm 簇编码阿霉素 A，一种蒽环类抗生素，比临床使用的天然蒽环类抗生素更有效，并保留对多药耐药 (MDR) 癌细胞的活性。
