Es wurden die Derivate 1–15 von 1‐Cyclopentyloxy‐, 1‐Cyclohexyloxy‐ und1‐Benzyloxy‐2‐hydroxy‐3‐aminopropanen durch Reaktion von 1‐substituierten 2,3‐Epoxypropanen mit primären Aminen synthetisiert. Die Epoxypropane wurden durch Kondensation der entsprechenden Alkohole mit Epichlorhydrin dargestellt. Die pharmakologische Prüfung der Hydrogenmaleate und Hydrogenfumarate der neuen Verbindungen ergab

A series of 1-aminopropan-2-ols were synthesized and evaluated against two strains of malaria, Plasmodium falciparum FCR3 (chloroquine-resistant) and 3D7 (chloroquine-sensitive). Microwave-assisted ring opening of epoxides (aryl and alkyl glycidyl ethers, glycidol, epichlorohydrin) with various amines without catalysts generated the desired library of beta-amino alcohols rapidly and efficiently. Most of the compounds showed micromolar potency against malaria, with seven of them having IC50 values between 1 and 10 mu M against both Plasmodium falciparum strains.
