Mono- and multimeric ferrocene congeners of quinoline-based polyamines as potential antiparasitics.

A series of mono- and multimeric polyamine-containing ferrocenyl complexes containing a quinoline motif were prepared. The complexes were characterised by standard techniques. The molecular structure of the monomeric salicylaldimine derivative was elucidated using single crystal X-ray diffraction and was consistent with the proposed structure.

Polyamine quinoline rhodium complexes: synthesis and pharmacological evaluation as antiparasitic agents against Plasmodium falciparum and Trichomonas vaginalis.

A series of mono- and bis-salicylaldimine ligands and their corresponding Rh(i) complexes were prepared. The compounds were characterised using standard spectroscopic techniques including NMR, IR spectroscopy and mass spectrometry. The salicylaldimine ligands and complexes were screened for antiparasitic activity against two strains of Plasmodium falciparum i.

Synthesis, characterization, antiparasitic and cytotoxic evaluation of thioureas conjugated to polyamine scaffolds.

A series of mono- and multimeric 4-amino-7-chloroquinoline and ferrocenyl thioureas have been prepared by the reaction of a 7-chloroquinoline methyl ester and a ferrocenylimine methyl ester with various amines. These compounds were characterized using standard spectroscopic and analytical techniques. The compounds were evaluated against the NF54 (CQ-sensitive) and Dd2 (CQ-resistant) strains of Plasmodium falciparum.
