Abstract
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; PA1 R.sub.2 is hydrogen, C.sub.1 -C.sub.10 alkyl or an amide-substituted alkyl having up to 10 carbon atoms; PA1 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 PA1 R.sub.2 and R.sub.3 are linked together to form an alkylene chain; and PA1 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.
