title: A new nitrosourea derivative TA-077, 1-(2-chloroethyl)-3-isobutyl-3-(beta-maltosyl)-1-nitrosourea. I. Comparative study on antitumor activity.
abstract: A new water-soluble nitrosourea derivative, 1-(2-chloroethyl)-3-isobutyl-3-(beta-maltosyl)-1-nitrosourea (TA-077), was tested for antitumor activity against murine tumors and a human mammary carcinoma (MX-1) implanted in athymic mice, and the results were compared with those obtained with five other nitrosourea derivatives currently in clinical use: 1-(2-chloroethyl)-3-(methyl-alpha-D-glucopyranos-6-yl)-1-nitrosourea (MCNU), 1-(2-chloroethyl)-3-(beta-D-glucopyranosyl)-1-nitrosourea (GANU), 3-[(4-amino-2-methyl-5-pyrimidinyl) methyl]-1-(2-chloroethyl)-1-nitrosourea hydrochloride (ACNU), chlorozotocin, and 1-(2-chloroethyl)-3-(4-methylcyclohexyl)-1-nitrosourea (Me-CCNU).
