Inducing DHT in human diabetes LNCaP cells and inhibiting their development are the two effects of delta-tocopherol (0-100 μM, 96 hours) on the cells[2]. In CWR-22Rv1/AR cells, delta-tocopherol (0-100 μM, 24 hours) suppresses the activation of androgen produced by DHT (10 nM) and its downstream target PSA [2]. In MCF-7 cells and MDA-MB-231 cells, delta-tocopherol (10 μM, 1-4 days) lowers estrogen-induced cyclin D1 and c-Myc levels [3].

Ptenp−/− mice treated with 0.2% food supplementation of delta-tocopherol for 28 weeks do not develop liver tumors [1]. Five weeks of 0.2% diet-based delta-tocopherol suppresses MCF-7 Xenograft tumor growth.

Animal/Disease Models: MCF-7 orthotopic xenograft model [3]
Doses: 0.2% in diet Administration time: 5 weeks Experimental Results: Inhibit tumor growth by 58%. |

| Additional Infomation |
Delta-tocopherol is a tocopherol in which the chroman-6-ol core is substituted by a methyl group at position 8. It is found particularly in maize (corn) oil and soya bean (soybean) oils. It has a role as a plant metabolite and a food antioxidant. It is a vitamin E and a tocopherol.
delta-Tocopherol has been reported in Guarea kunthiana, Glycine max, and other organisms with data available. Delta-Tocopherol is the orally bioavailable delta form of the naturally-occurring fat-soluble vitamin E, mostly found in soybean and corn oils, with potential antioxidant activity. Although the exact mechanism of action of this tocopherol has yet to be fully identified, delta-tocopherol appears to have the ability to scavenge free radicals, thereby protecting cells against oxidative damage. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.17 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (5.17 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.08 mg/mL (5.17 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
