Induction of tumor degeneration by sodium benzylideneascorbate.

Author information

First Department of Biochemistry, School of Medicine, Showa University, Tokyo, Japan.


Intravenous administration of sodium benzylideneascorbate (SBA) rapidly necrotized inoperable human lung cancer, and induced degeneration of 3'-methyl-4-dimethylaminoazobenzene-induced rat hepatocellular carcinoma (vacuolar, eosinophilic degeneration, nuclear debris) without affecting the serum glutamic oxaloacetic transaminase, gamma-glutamyl transpeptidase and total protein levels. Cultured normal human lung and skin fibroblasts, and human glioma and glioblastoma cell lines were relatively resistant to SBA, when compared to human myelogenous leukemic cell lines. SBA had no apparent host immunopotentiation activity such as stimulation of cytokine action or production; activation of monocyte or polymorphonuclear cells; or modulation of poly (ADP-ribose) glycohydrolase activity. The data suggest that the antitumor activity of SBA might be produced by direct action of authentic SBA or its metabolized form(s), rather than by immunopotentiation of the hosts.
