产品描述 | L-Ascorbic acid sodium salt (Vitamin C sodium salt) is a more bioavailable form of vitamin C that is an alternative to taking ascorbic acid as a supplement. |
体外活性 | Sodium ascorbate has a growth inhibiting action only at high concentrations in cultured human neoplastic cell lines MCF-7 (breast carcinoma), KB (oral epidermoid carcinoma), and AN3-CA (endometrial adenocarcinoma). Sodium ascorbate combined with vitamin K3 demonstrates a synergistic inhibition of cell growth at 10 to 50 times lower concentrations in cultured human neoplastic cell lines MCF-7, KB, and AN3-CA, at this level separately given vitamins are not toxic. This tumor cell growth inhibitory effect is completely suppressed by the addition of catalase to the culture medium containing vitamins C and K3, suggesting an excessive production of hydrogen peroxide as being implied in mechanisms responsible for the above-mentioned effects. [1] Sodium ascorbate combined with vitamin K3 results in a synergistic effect on growth inhibition in cultured human endometrial adenocarcinoma (AN3CA) cells. [2] Sodium ascorbate results in a rapid increase in the intracellular concentration of Ca2+ ions and subsequent apoptotic cell death in HL-60 cells, characterized by cell shrinkage, nuclear fragmentation and cleavage of internucleosomal DNA to yield fragments that are multiples of 180-200 base pairs, are induced. [3] Sodium ascorbate (100 μM) induces DNA single-strand breaks in human cells, Fibroblasts and Molt-4 cells are significantly more sensitive than lymphocytes. Sodium ascorbate (50 μM) results in significant cell loss in Molt-4 cells, but not in lymphocyte and fibroblast cultures. [4] |
体内活性 | Tg rats treated with sodium?L-ascorbate show a higher incidence of carcinoma (29.6%), compared to those without sodium?L-ascorbate (15.4%). Independent of the sodium?L-ascorbate treatment, transgenic rats exhibit various kinds of malignant tumors in various organs[5]. 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 sodium?L-ascorbate-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 sodium?L-ascorbate-treatment is evident only with simple hyperplasias and PN hyperplasias in rats[6]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
