Improved means for the chemotherapy of malaria have been achieved with 5-oxy-primaquine analogues having the formula: ##STR1## wherein R.sub.4 represents hydrogen or a methyl grouping, and R represents an alkyl group containing 3 to 12 carbon atoms and pharmaceutically acceptable salts thereof, wherein the salt-forming acid may be organic or inorganic in nature. These primaquine-related compounds afford improvement in the chemotherapy of malaria by exerting plasmodicidal action on malaria parasites which may be present in either the blood, formed tissues, or blood and formed tissues of the mammalian host. Such broad and practical spectrum of effectiveness distinguishes the said primaquine analogues, which may be administered parenterally or perorally to infected animals.
已实现改进的疟疾化疗手段,采用具有以下结构式的5-氧基伯喹类似物:##STR1## 其中R.sub.4代表氢或甲基基团,R代表含有3至12个碳原子的烷基基团及其药用可接受盐,其中盐形成酸可以是有机的或无机的。这些伯喹相关化合物通过对可能存在于哺乳动物宿主的血液、组织或血液和组织中的疟原虫产生疟疾杀灭作用,从而改善了疟疾的化疗效果。这种广泛而实用的有效性范围区分了所述的伯喹类似物,可以通过注射或口服的方式给感染的动物使用。
