Compounds of the class including 4-methyl-5-(unsubstituted and substituted henoxy)-6-methoxy-8-(aminoalkylamino)quinolines as the free bases and pharmaceutically acceptable acid amine salts are described. The compounds are highly effective antimalarial agents which possess, surprisingly, both tissue schizonticidal (radical curative) and blood schizonticidal (suppressive) activity. In addition, these drugs have significantly better therapeutics indices than primaquine which is the current tissue schizonticidal drug of choice. Primaquine possesses no useful blood schizonticidal activity at tolerated dose levels.

喹啉作为自由碱和药学上可接受的酸胺盐。这些化合物是高效的抗疟疾药物,令人惊讶的是,它们具有组织红细胞分裂体杀灭(根治性)和血液红细胞分裂体杀灭(抑制性)活性。此外,这些药物的治疗指数显著优于普利昂奎,后者是目前组织红细胞分裂体杀灭药物的首选药物。普利昂奎在可耐受的剂量
水平下没有有用的血液红细胞分裂体杀灭活性。
