The present invention relates to novel 2-aminocarbonyl-1,2-bis(methylsulfonyl)-1-(2-chloroethyl)hydrazines and 2-aminocarbonyl-1,2-bis(methylsulfonyl)-1-methylhydrazines, and their use to treat malignant tumors. The agents are especially useful in the treatment of animal and human cancers. Two preferred agents in this class, especially for use in the treatment of tumors are 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)-2-(2-chloroethyl)aminocarbonylhy drazine and 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)-2-methylaminocarbonylhydrazine. These agents are characterized by the following: they are incapable of undergoing inactivation by the denitrosation mechanism proposed for the inactivation of the CNUs; they are incapable of generating a hydroxyethylating species by the mechanism proposed for the CNUs; and they are capable of chloroethylation or methylation and carbamoylation.
本发明涉及新颖的2-氨基羰基-1,2-双(甲磺酰基)-1-(2-氯乙基)肼和2-氨基羰基-1,2-双(甲磺酰基)-1-甲基肼,以及它们用于治疗恶性肿瘤。这些药物在动物和人类癌症的治疗中特别有用。在这一类别中,特别适用于肿瘤治疗的两种首选药物是1,2-双(甲磺酰基)-1-(2-氯乙基)-2-(2-氯乙基)氨基羰基肼和1,2-双(甲磺酰基)-1-(2-氯乙基)-2-甲基氨基羰基肼。这些药物具有以下特点:它们无法通过被提出用于CNUs失活的去亚硝化机制而失活;它们无法通过被提出用于CNUs的生成羟乙基化物种的机制而生成;它们能够进行氯乙基化或甲基化和羰基化。
