title: Protective effects of WR-2721 against radiation-induced injury of murine gut, testis, lung, and lung tumor nodules.
abstract: WR-2721 (S-2-(3 aminopropylamino) ethylphosphorothioic acid) has been investigated for its ability to protect gut, lung, and testis, as well as fibrosarcoma (FSa) tumor nodules, in the lungs of mice from gamma-radiation injury. This compound greatly protected jejunum and testis epithelial cells. FSa micrometastases in the lung were protected to a lesser extent than jejunum and testis. Conversely, WR-2721 was not able to protect the lung against radiation-induced enhancement of tumor metastases formation generated by intravenously injected FSa cells.
