The human African trypanosomiasis is a neglected tropical disease, which is caused by the protozoan Trypanosoma brucei and transmitted by the bite of the tsetse fly. An untreated infection leads to death. However, only a few drugs with significant drawbacks are currently available for treatment. In this thesis, quinolone amides with an antitrypanosomal activity were synthesized and their biological and physicochemical properties were measured. New structure-activity relationships and a promising lead structure were discovered.
Synthesis and biological activity of molybdenum carbonyl complexes and their peptide conjugates
(2012)
Molybdenum carbonyl complexes with different polypyridyl coligands were prepared and conjugated to peptides by mild bioorthogonal coupling reactions like the oxime ligation and a catalyst-free azide-alkyne click reaction utilized for the first time in such a context. The biological activity of some of the new complexes and conjugates, including their CO release properties, cytotoxicity on human cancer cells, and mode of induction of cell death was studied.
