The novel compounds 3-(arylmethyl)-1-(3'-diethylaminopropyl) pyrrolidines are disclosed which have the general formula:
wherein R represents an alkoxy group having 1 to 6 carbon atoms, like methoxy, ethoxy, propoxy or butoxy and a process for preparing the same. Particularly, the invention provides the compound having the above said formula wherein the alkoxy substituent is in the 4 position of the benzene ring or the substituent methylenedioxy at 3 and 4 position. The compounds have the property of reversing the resistance of chloroquine resistant strains of the malarial parasite P. berghi in vivo and P. falciparum in vitro and can be used for reversing the resistance of human malarial parasites, particularly P. falciparum. The invention also includes compositions containing the new compounds and an anti-malarial drug, preferably chloroquine.
本发明揭示了一种新型化合物3-(芳基甲基)-1-(3'-二乙基氨基丙基)吡咯烷,其具有以下通式:
其中R代表1至6个碳原子的烷氧基,例如甲氧基、乙氧基、丙氧基或丁氧基,并提供一种制备该化合物的方法。特别地,本发明提供了上述通式中烷氧基取代基位于苯环的4位或取代基为3和4位的亚甲二氧基。该化合物具有在体内逆转氯喹耐药性疟原虫P. berghi和体外逆转P. falciparum的特性,并可用于逆转人类疟原虫,特别是P. falciparum的耐药性。本发明还包括含有新化合物和抗疟药物(优选为氯喹)的组合物。
