NAMI-A, imidazolium trans-imidazoledimethylsulfoxidetetrachlororuthenate, is a ruthenium based compounds capable of inhibiting the growth of lung metastases of solid tumours in a number of experimental conditions.The aim of this study was to investigate the potential use of NAMI-A by the oral route to treat lung metastases of MCa mammary carcinoma in the CBA mouse. treatment of mice, carrying intramuscular tumours in advanced stage of growth, for 11 consecutive days caused a significant reduction of the weight of lung metastases over the range of doses from 150 to 600 mg/kg/day. No sign of toxicity was observed at the histological analysis in the gut epithelium or in the kidney parenchyma, and NAMI-A concentration in the kidney was more than 10-fold lower than after intraperitoneal treatments. NAMI-A is thus active against metastases also by the oral route, suggesting the use of this way to treat tumour bearing hosts for long periods.
