Disclosed are novel bis-dioxopiperazine derivatives and non-toxic salts thereof, process for their preparation, antitumor agents comprising them and compositions containing them. The bis-dioxopiperazine derivatives are represented by the following general formula (I): ##STR1## wherein R represents an alkyl radical having 1 to 17 carbon atoms, a cycloalkyl radical having 3 to 7 carbon atoms, a lower alkyl radical having a substituent or substituents selected from the group consisting of halogeno, carboxy, alkoxycarbonyl having 2 to 5 carbon atoms, lower alkoxy, substituted or unsubstituted phenoxy, naphthyloxy, substituted or unsubstituted phenylthio, substituted or unsubstituted phenyl and naphthyl, a substituted or unsubstituted phenyl lower alkenyl radical, a substituted or unsubstituted phenyl radical, a naphthyl radical, a heterocyclic radical selected from the group consisting of pyridyl, furyl and thienyl, an alkoxy radical having 1 to 8 carbon atoms, a substituted or unsubstituted phenyl lower alkoxy radical, or a substituted or unsubstituted phenoxy radical. A substituent or substituents on R may be selected from the group consisting of lower alkyl, halogeno, lower alkoxy, acyloxy having 2 to 5 carbon atoms, methylenedioxy, carboxy, amino, methanesulfonylamino and nitro. The above-mentioned "lower alkyl", "lower alkoxy" and "lower alkenyl" respectively refer to alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms and alkenyl having 2 to 4 carbon atoms.
揭示了新颖的双二氧哌嗪衍生物及其无毒盐,其制备方法,包含它们的抗肿瘤剂和含有它们的组合物。双二氧哌嗪衍生物由以下一般式(I)表示:##STR1##其中R代表具有1至17个碳原子的烷基基团,具有3至7个碳原子的环烷基基团,具有来自卤素、羧基、具有2至5个碳原子的烷氧羰基、辅基或辅基的下位烷氧基、取代或未取代的苯氧基、萘氧基、取代或未取代的苯硫基、取代或未取代的苯基和萘基、取代或未取代的苯下位烯基基团、取代或未取代的苯基基团、萘基团、选自吡啶基、呋喃基和噻吩基的杂环基团、具有1至8个碳原子的烷氧基、取代或未取代的苯下位烷氧基团,或取代或未取代的苯氧基团。R上的辅基或辅基可选自下位烷基、卤素、下位烷氧基、具有2至5个碳原子的酰氧基、亚甲二氧基、羧基、氨基、甲磺酰氨基和硝基的群。上述“下位烷基”、“下位烷氧基”和“下位烯基”分别指具有1至4个碳原子的烷基,具有1至4个碳原子的烷氧基和具有2至4个碳原子的烯基。
