Development of methods that allow immediate and safe removal of sulfur-containing gases is of the utmost priority. Direct desulfurization of the blood（１）of cancer patients and development of new compounds that can inactivate sulfur compounds are various new approaches being taken towards cancer therapy. Our laboratory has been working on the development of a new compound that can rapidly metabolize sulfur-containing gases. Our preliminary work has demonstrated a reduction in tumor size using this compound to remove internalized sulfur-containing gases (manuscript in preparation). If we can develop a highly efficacious drug that could be used in the clinic, a new cancer therapy that spares the body from heavy burden can be established, ultimately leading to prevention of metastasis and cancer relapse.
