The synthesis and full 3D structural characterization of nine new 1-benzenesulfonyl-2-methyl-1,2,3,4-tetrahydroquinoline derivatives are reported. These belong to a library whose rationale for the design was the previous knowledge of the biological relevant properties of both structural moieties. From protozoan antiparasitic screening, compounds 3 demonstrated interesting activity against Trypanozoma cruzi with low cytotoxicity. Besides, most compounds were moderately active against Plasmodium falciparum. Of these, 3 and 9 can be considered as lead scaffolds for further optimization. The substituent on BS did not influence the 3D structure properties and the H-1 NMR spectra revealed the existence of an intramolecular weak hydrogen bond, C-H center dot center dot center dot O=S. Molecular modeling and X-ray crystallography also confirmed this finding, which is relevant to compound conformational preference. (C) 2009 Elsevier Ltd. All rights reserved
