N. Bharti et al., Synthesis and antiamoebic activity of new cyclooctadiene ruthenium(II) complexes with 2-acetylpyridine and benzimidazole derivatives, BIOORG MED, 10(20), 2000, pp. 2243-2245
Reaction of [RU(eta (4)-C8H12) (CH3CN)(2) Cl-2] with 2-(2-pyridyl) benzimid
azole or Schiff bases derived from 2-acetylpyridine and S-methyldithiocarba
zate, S-benzyldithiocarbazate and thiosemicarbazide leads to form new compl
exes of the type [RU(eta (4-) C8H12)(L)Cl-2] (where L=ligand). In vitro, mo
st of the compounds exhibited potent activity and the Ru derivatives 1a [RU
(eta (4)- C8H12)(2-Acpy-SMDT)Cl-2, 2a [Ru(eta (4)-C8H12)(2-Acpy-SBDT)Cl-2]
and 3a [Ru(eta (4)-C8H12)(2-Acpy-TSC)Cl-2] were found more active than metr
onidazole against (HK-9) strain of Entamoeba histolytica. (C) 2000 Elsevier
