During the course of in vitro screening of agents which are preferentially active against ras oncogene-expressed cells, a new anthracycline (identified as 2-demethylsteffimycin D) and a heptaene (possibly a new member of partricins) were isolated from microbial fermentation broths. Among known compounds tested, 5-fluorouracil, 5-fluorodeoxyuridine and oxanosine showed high selectivity towards ras oncogene-expressed cells.
在对优先作用于表达ras癌基因的细胞的药物进行体外筛选过程中，从微生物发酵液中分离出一种新的蒽环类抗生素（鉴定为2-去甲基司替米星D）和一种七烯类化合物（可能是盘尼西林类的新成员）。在所测试的已知化合物中，5-氟尿嘧啶、5-氟脱氧尿苷和氧杂核苷对表达ras癌基因的细胞表现出高选择性。
