Degradation products of 1-(2-chloroethyl)-3-(4-substituted-2, 3-dioxo-1-piperazinyl)-alkyl-1-nitrosourea in aqueous solution were investigated. Among them, a symmetrical urea derivative, 1, 3-bis [4-(4-ethyl-2, 3-dioxo-1-piperazinyl) butyl] urea (3c), was found to have antitumor activity. A synthetic unsymmetrical urea derivative, 1-[2-(4-ethyl-2, 3-dioxo-1-piperazinyl) ethyl]-3-methylurea (4a), also showed antitumor activity against Ehrlich carcinoma (solid form).
在水溶液中研究了1-(2-氯乙基)-3-(4-取代-2,3-二酮-1-哌嗪基)-烷基-1-亚硝脲的降解产物。其中发现一种对称的脲衍生物,1,3-双[4-(4-乙基-2,3-二酮-1-哌嗪基)丁基]脲(3c),具有抗肿瘤活性。一种合成的不对称脲衍生物,1-[2-(4-乙基-2,3-二酮-1-哌嗪基)乙基]-3-甲基脲(4a),也表现出对Ehrlich癌(固体形式)的抗肿瘤活性。
