A microbiological assay has been developed for chromomycin A(3), an antitumor antibiotic showing promise in human trials. The assay bacterium is a derived strain of Streptococcus faecalis resistant to methotrexate. Studies with mice revealed that relatively high concentrations of this antibiotic were maintained in the blood, kidneys, and liver of mice after a single-dose intraperitoneal injection of the drug.
已开发出一种用于色霉素A(3)的微生物测定法,色霉素A(3)是一种在人体试验中显示出前景的抗肿瘤抗生素。测定用细菌是对甲氨蝶呤耐药的粪链球菌衍生菌株。对小鼠的研究表明,单次腹腔注射该药物后,小鼠的血液、肾脏和肝脏中能维持相对较高浓度的这种抗生素。
