Sodium ascorbate [134-03-2]

Ascorbate, also known as Ascorbicin, is a DNase I inhibitor. Ascorbate is an antioxidant which functions as a reducing agent and coenzyme in several metabolic pathways.(In Vitro):The conditioned medium for B16F10 cells significantly inhibits cell apoptosis induced by L-Ascorbic acid sodium salt (Sodium L-ascorbate) (10 mM), and the effective ingredients in the medium show a relative molecular mass below 5,000.(In Vivo):Tg rats treated with L-Ascorbic acid sodium salt (Sodium L-ascorbate) show a higher incidence of carcinoma (29.6%), compared to those without L-Ascorbic acid sodium salt (15.4%). Independent of the L-Ascorbic acid sodium salt treatment, transgenic rats exhibit various kinds of malignant tumors in various organs.After 12 weeks of PEITC-treatment, both simple hyperplasia and papillary or nodular (PN) hyperplasia have developed in all animals, but the majority of these lesions have disappeared at week 48, irrespective of the L-Ascorbic acid sodium salt-treatment. The same lesions after 24 weeks of PEITC-treatment have progressed to dysplasia and carcinoma, in a small number of cases by week 48, but enhancement by the L-Ascorbic acid sodium salt-treatment is evident only with simple hyperplasias and PN hyperplasias in rats.
