Synthesis of new tetrahydropyridinylidene ammonium salts and their antiprotozoal potency

摘要

Several new tetrahydropyridinylidene ammonium salts were prepared by selective reduction. They were characterized using UV-Vis spectroscopy, FT-IR spectroscopy, and HRMS. Their structure was established by NMR spectroscopy and a single X-ray structure analysis. One compound shows a distinct antiplasmodial potency (IC50 = 0.34 mu Ie) against the multiresistant K-1-strain of Plasmodium falciparum and low cytotoxicity (IC50 = 199.8 mu Ie) against L-6 cells (rat skeletal myoblasts).
