Abstract
The ruthenium complex was administered to female Crl:WI rats orally, by gastric intubation and intraperitoneal injection. The hematological parameters and the histopathological changes in liver, kidneys, spleen and brain were investigated after a 14-days treatment. The substance was very well tolerated orally, with a LD50 value of over 2000 mg/kg body weight. Symptoms were observed only in the first day after intraperitoneal administration of the highest dose, with a LD50 value between 300 and 2000 mg/kg bw. The hematological profile was not modified at any of the tested doses, after both oral and intraperitoneal acute administration. Structural modifications (moderate lymphocytolysis) were identified only in the spleen at the highest tested dose. In conclusion, the thiazolo arene ruthenium complex was very well tolerated orally and had a low acute toxicity after intraperitoneal administration in Crl:WI rats The results justify further investigation to determine the in vivo therapeutic potential of this promising ruthenium complex.
