Imidazolyl derivatives of the formula ##SPC1## Or a tautomer or structural isomer thereof, wherein R.sub.1 is a carbocyclic or heterocyclic aromatic group unsubstituted or substituted by one or more halogen, unsubstituted or substituted hydroxyl, amino, thiol, sulphonic or carbocyclic groups, cyano, nitro, acyl, alkyl, aryl or haloalkyl; R.sub.2 is amino or hydroxyl, or alkoxyl, aryloxyl or aralkoxyl unsubstituted or substituted by one or more halogen, or unsubstituted or substituted hydroxyl or tertiary amino; R.sub.4 is a negative charge when R.sub.3 is N.sub.2.sup.+ of R.sub.4 is hydrogen or C.sub.1.sub.-6 alkyl when R.sub.3 is N=NR.sub.5 R.sub.6, wherein R.sub.5 is methyl or halogen .beta.-substituted ethyl and R.sub.6 is hydrogen, a hydrocarbon unsubstituted or substituted by halogen, or an unsubstituted or substituted hydroxyl or tertiary amino; or an acid addition salt, solvate or solvated acid addition salt thereof; Are useful for their bacteriocidal and antifungal activity and for their antitumor activity against R1 lymphoma, ADJ/PC6 plasma cell tumor and Friend Leukaemia in mice. The imidazole derivatives, wherein R.sub.3 is N.sub.2.sup.+ and R.sub.4 is a negative charge, are intermediates particularly useful in the production of the final product imidazoles having the above specified utilities.
咪唑衍生物的化学式为##SPC1##,或其互变异构体或结构异构体,其中R.sub.1是未取代或取代的一个或多个卤素、未取代或取代的羟基、氨基、硫醇、磺酸基或碳环族群、氰基、硝基、酰基、烷基、芳基或卤代烷基的碳环族群的碳环或杂环芳香族群;R.sub.2是未取代或取代的氨基或羟基,或未取代或取代的烷氧基、芳氧基或芳基烷氧基,其中取代的一个或多个卤素,或未取代或取代的羟基或三级氨基;当R.sub.3为N=NR.sub.5R.sub.6时,R.sub.4为负电荷,其中R.sub.5为甲基或卤代β-取代的乙基,R.sub.6为氢、未取代或取代的碳氢族群、或未取代或取代的羟基或三级氨基;或其酸加合物、溶剂合物或溶剂化酸加合物;对它们的细菌杀灭和抗真菌活性以及对R1淋巴瘤、ADJ/PC6浆细胞瘤和小鼠朋友白血病的抗肿瘤活性是有用的。其中R.sub.3为N.sub.2.sup.+且R.sub.4为负电荷的咪唑衍生物是中间体,特别适用于生产具有上述用途的最终产品咪唑。
