Antitumor agents and immunosuppressants (I):
wherein R is a monosubstituted benzoyl group in which the substituent is (a) a phenyl, alkanoyl, formyl, halogenoalkyl, aralkyloxy, phenoxy, alkoxycarbonyl, aralkyloxycarbonyl alkanoyloxy, benzoyl, carboxyl, hydroxy, aralkyloxycarbonylamino, lower alkoxycarbonylamino, carboxyamino or carbamoyl group or a group (IV)
(wherein X, and X2 are each independently hydrogen or lower alkyl); (b) a cinnamoyl group which may be substituted at the a-position and/or the phenyl ring with one or more substituents selected independently from alkyl, alkoxy, aryl, nitro, methylenedioxy, formyl, halogenoalkyl, hydroxy, carboxyl, amino and cyano groups and halogens or (c) a benzoyl group substituted with from two to five substituents selected independently from alkyl, alkoxy, aralkyloxy, nitro, hydroxy, alkanoyloxy, formyl, carboxyl, alkylthio, alkylsulfonyl, sulfo and sulfamoyl groups, halogens, and groups (IV) above; and non-toxic salts thereof. They are obtained from 4-carbamoylimidazolium-5-olate and the corresponding acids ROH.

其中 R 是单取代的苯甲酰基,其取代基是 (a) 苯基、烷酰基、甲酰基、卤代烷基、烷氧基、苯氧基、烷氧羰基、烷氧羰基烷酰氧基、苯甲酰基、羧基、羟基、烷氧羰基氨基、低级烷氧羰基氨基、羧基氨基或氨基甲酰基或基团 (IV)
(其中 X 和 X2 各自独立地为氢或低级烷基);(b) 肉桂酰基,可在 a 位和/或苯环上被一个或多个取代基取代,取代基独立选自 烷基、烷氧基、芳基、硝基、亚甲基二氧基、甲酰基、卤代烷基、羟基、 羧基、氨基和氰基以及卤代烷基、或 (c) 被 2 至 5 个独立选自烷基、烷氧基、芳氧基、硝基、羟基、烷甲酰氧基、甲酰基、羧基、烷硫基、烷基磺酰基、磺酰基和氨基磺酰基、卤素和上述基团 (IV) 的取代基取代的苯甲酰基;及其无毒盐类。它们由 4-氨基甲酰基咪唑鎓-5-醇和相应的酸 ROH 制得。
