title: [The search for new antiparasitic agents. 10. The synthesis, toxicological and antimalarial properties of nitrogen-containing heterocycles with a 4-(4-alkylpiperazinyl-1) phenylamine substituent (the preparation quinoprazine)].
abstract: Synthesis is described and acute toxicity and antimalaria action is studied in new derivatives of quinoline and benzo(g)quinoline containing a 4-(4-alkylpiperazinyl-1)phenylamine substitute. Only the derivatives of benzo(g)quinoline were found to have a high antimalaria effect and to have advantages over the standard agent chloroquine on their tolerance and protective action. One of the compounds, 4-[4-(4-ethylpiperazinyl-1)phenylamino] benzo(g)quinoline, named QUINOPRAZINE, showed some action against Plasmodium berghei chloroquine--resistant infection (isolate LN-K65). This agent was elected for further tests.
