A number of aromatic nuclei are associated with significant antimalarial activity when attached to N-alkylaminoethanol or a-piperidylmethanol side chains. A series of N- monoalkyl-and N, N-dialkylaminopropanol side chains have now been attached to a series of these active nuclei. The preparation and antimalarial activity of the aminopropanol variants are described. The antimalarial bioassay data for the title compounds show an ...
