Abstract
Abstract The present invention relates to the use of a compound of formula (I) ##STR1## wherein R represents a hydrogen atom; a C 1-4 alkyl group; a group COR 1 wherein R 1 represents amino or C 1-4 alkoxy; or a group --CH 2 R 2 wherein R 2 represents a halogen atom (e.g. chlorine or bromine), C 1-4 alkylthio, or azido, X and Y each independently represent --CH-- or --N; and Z represents --CR 3 , wherein R 3 is hydrogen or C 1-4 alkyl, or Z represents --N--; or a physiologically acceptable salt, ester or other physiologically functional derivative thereof, for the manufacture of a medicament for the treatment and/or prophylaxis of a parasitic infection in a mammal, and to certain novel compounds of formula (I), pharmaceutical compositions containing them and processes for their preparation.
