Beneficial effects of a vanadium complex with cysteine, administered at low doses on benzo(alpha)pyrene-induced leiomyosarcomas in Wistar rats.

Abstract

Vanadyl sulfate, cysteine and V(III)-cysteine complex exerted antitumor effects in tumor bearing rats. The V(III)-cysteine complex, however, exerts much more potent effects, as evident from the results of the present study. These beneficial effects of the above complex, in combination with its low toxicity provide evidence suggest its possible application in the treatment of human malignant diseases.
