There are disclosed 7-chloro-3-substituted aryi-3,4-dihy- dro-1,9(2H,10H) and 10-hydroxy acridinedioneimines, processes for their production and pharmaceutical compositions containing such compounds. The novel compounds have the following formula:
where Y is a hydrogen atom or hydroxy group; R1 is a hydrogen, fluorine, chlorine, bromine or iodine atom; each of R2 and R3, which are the same or different, is a hydrogen, fluorine, chlorine, bromine or iodine atom or a trifluoromethyl group;
wherein n is zero or an integer from 1 to 5; each of R4 and R5, which are the same or different, is a hydrogen atom or an alkyl radical containing one to four carbon atoms, -CH2-CH2-OH,
allyl, or R4 and R5 together are (CH2)4 to 5. or
each of R6 and R7, which are the same or different, is hydrogen, methyl or ethyl; and R8 is hydrogen or methyl. The invention extends to the pharmaceutically acceptable salts of these compounds. The novel compounds and their salts are suitable for use in the prevention and cure of protozoal infections and have a high activity against malaria parasites.
