[Antineoplastic activity of lambdamycin in different murine test models compared with cyclophosphamide, 6-mercaptopurine and 5-fluorouracil (author's transl)]

Lambdamycin, a chromoglycoside antibiotic like chartreusin was found to be very active against leukemias L 1210 and P 388 and moderate effective against melanoma B 16 and Lewis lung carcinoma of mice. It was nearly without any effect when tested on Walker 256 carcinoma of rats. The effectiveness of lambdamycin was compared with that of cyclophosphamide, 5-fluorouracil and 6-mercaptopurine.
