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.
本类化合物包括4-甲基-5-(未取代和取代的苯氧基)-6-甲氧基-8-(氨基烷基)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,出人意料地具有组织无性红体杀灭(根治性)和血液无性红体杀灭(抑制性)活性。此外,这些药物的治疗指数显著优于目前组织无性红体杀灭药物首选的前奎宁。在可耐受的剂量水平下,前奎宁没有有用的血液无性红体杀灭活性。
