Synthesis and anti-trypanosomal activity of novel 5-nitro-2-furaldehyde and 5-nitrothiophene-2-carboxaldehyde semicarbazone derivatives
摘要:
Several novel semicarbazones derivatives were prepared from 5-nitro-2-furaldehyde or 5-nitrothiophene-2-carboxaldehyde, and tested in vitro as potential anti trypanosomal agents. The compounds were prepared in good to excellent yields in 2-3 steps from readily available starting materials. Some derivatives were found to be active against Trypanosoma cruzi with an activity similar to that of Nifurtimox. (C) 1998 Elsevier Science S.A. All rights reserved.

yields by reaction of [RuIICl2(dmso)4] with L in ethanol or toluene solutions. Complexes were characterized by elemental analyses and electronic, FTIR, 1H and 13C NMR spectroscopies. Crystal and molecular structures of [RuCl2(dmso)2L1] and [RuCl2(dmso)2L2] were determined by X-ray diffraction methods. In both crystals the ruthenium metal atom is in a quite similar elongated octahedral environment, equatorially
