Abstract
The discovery of novel drugs against animal parasites is in high demand due to drug-resistance problems encountered around the world. Herein, the synthesis and characterization of 27 organic and organometallic derivatives of the recently launched nematocidal drug monepantel (Zolvix® ) are described. The compounds were isolated as racemates and were characterized by 1 H, 13 C, and 19 F NMR spectroscopy, mass spectrometry, and IR spectroscopy, and their purity was verified by microanalysis. The molecular structures of nine compounds were confirmed by X-ray crystallography. The anthelmintic activity of the newly designed analogues was evaluated in vitro against the economically important parasi..
