title: Synthesis and antiamoebic activity of new cyclooctadiene ruthenium(II) complexes with 2-acetylpyridine and benzimidazole derivatives.
abstract: Reaction of [Ru(eta4-C8H12) (CH3CN)2 Cl2] with 2-(2-pyridyl) benzimidazole or Schiff bases derived from 2-acetylpyridine and S-methyldithiocarbazate, S-benzyldithiocarbazate and thiosemicarbazide leads to form new complexes of the type [Ru(eta4-C8H12)(L)Cl2] (where L=ligand). In vitro, most of the compounds exhibited potent activity and the Ru derivatives 1a [Ru(eta4-C8H12)(2-Acpy-SMDT)Cl2], 2a [Ru(eta4-C8H12)(2-Acpy-SBDT)Cl2] and 3a [Ru(eta4-CsH12)(2-Acpy-TSC)Cl2] were found more active than metronidazole against (HK-9) strain of Entamoeba histolytica.
