Abstract (eng)
Despite its big role in history, nearly half of the world’s population is estimated to be at risk of malaria at the present day. World Health Organization (WHO) estimates that 207 million cases of malaria occurred globally in 2012 and estimates that 627,000 deaths are attributa-ble to malaria. There is still a long way to go until malaria will be eradicated and a vast number of medications became useless due to development of resistances. Therefore, new antimalarial agents are still much in demand.
Within this thesis, a structure-activity relationship of amidophenoxypropanolamines, which were primordially derived from the antiarrhythmic agent propafenone, is presented. Among them are a vast number of highly active compounds, more active than lumefantrine and artesunate. Furthermore, mice infected with Plasmodium berghei were cured with compounds synthesized in the course of this thesis. This proves the drug-likeness featured by the presented compounds. In addition, cytotoxicity, receptor binding, genetic toxicity and cardiac toxicity assays were performed, stating that the tested class of compounds may serve as a rich source for serious drug candidates.
Structural elucidation with crystallographic structure analysis and methods of nuclear mag-netic resonance (NMR) spectroscopy revealed an intriguing intramolecular network of hy-drogen bonds in these aminoalcohols is responsible for the antimalarial activity.
