Synthetically produced substantially pure biologically active compounds having the general formula ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.20 alkyl, alkenyl, aryl, aralkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, cycloalkenyl, alkylcycloalkenyl, or cycloalkenylalkyl; R.sub.2 is hydrogen, C.sub.1 -C.sub.10 alkyl or an amide-substituted alkyl having up to 10 carbon atoms; R.sub.3 is a cyclic, straight or branched chain hydrocarbon group having 2-12 carbon atoms, particularly --(CH.sub.2).sub.n --, wherein n is 2-12; or R.sub.2 and R.sub.3 are linked together to form an alkylene chain; and R.sub.4 is selected from ##STR2## (substituted or unsubstituted carbamimidoyl), ##STR3## (dimethylpyrimidyl), or ##STR4## (carbamyl) wherein each of R.sub.5, R.sub.6, and R.sub.7 is hydrogen or the same or different C.sub.1 -C.sub.8 alkyl group. The compounds are useful as bactericides for a wide variety of bacteria, including S.pyogenes, B.subtilis, K.pneumoniae, M.avium, B.fragilis, C.perfringens and C.albicans.
综合制备具有一般式##STR1##的基本纯生物活性化合物,其中R.sub.1是C.sub.1-C.sub.20烷基,烯基,芳基,芳基烷基,环烷基,烷基环烷基,环烷基烷基,环烯基,烷基环烯基或环烯基烷基;R.sub.2是氢,C.sub.1-C.sub.10烷基或具有最多10个碳原子的酰胺取代的烷基;R.sub.3是具有2-12个碳原子的环状,直链或支链烃基,特别是--(CH.sub.2).sub.n--,其中n为2-12;或R.sub.2和R.sub.3相互连接形成烷基链;R.sub.4从##STR2##(取代或未取代的氨基甲酰基),##STR3##(二甲基嘧啶基)或##STR4##(氨基甲酰基)中选择,其中R.sub.5,R.sub.6和R.sub.7中的每个都是氢或相同或不同的C.sub.1-C.sub.8烷基。这些化合物可用作广谱细菌杀菌剂,包括S.pyogenes,B.subtilis,K.pneumoniae,M.avium,B.fragilis,C.perfringens和C.albicans的各种细菌。
