D-gamma-Tocotrienol Usage And Synthesis
Description
γ-Tocotrienol is a form of vitamin E that has been found in rice bran and has diverse biological activities. It reduces cell death induced by hydrogen peroxide, paraquat, S-nitrocysteine, SIN-1 , or L-buthionine-(S,R)-sulfoximine (BSO; ) in rat striatal cultures when used at concentrations ranging from 0.1 to 10 μM. γ-Tocotrienol (20 μM) induces apoptosis in malignant sympathoadrenal (+SA) mouse mammary epithelial cells. In vivo, γ-tocotrienol (15, 30, and 150 mg/kg) reduces blood pressure and plasma lipid peroxide levels in spontaneously hypertensive rats. [Matreya, LLC. Catalog No. 2111]
Chemical Properties
g:d:aTocotrienol 1.6:0.4:1
Uses
γ-Tocotrienol exhibits antioxidant properties and belongs to the vitamin E family. It is naturally found in wheat germ oil and bran. In addition, α-tocopherol and γ-tocotrienol derivatives are potential lead compounds for developing?anticancer and?antiproliferative agents against?MCF-7 and MDA-MB-231 breast cancer cells and the A549 lung cancer cells.
Definition
ChEBI: A tocotrienol that is chroman-6-ol substituted by methyl groups at positions 2, 7 and 8 and a farnesyl chain at position 2.
in vivo
γ-Tocotrienol’s liposomal formulation, GT3-Nano (20 mol% γ-Tocotrienol), (10 mg/kg, 6 mol%; i.v.; single dose, observed for 100 d) is highly effective in mitigating the marrow-suppressive effects of sublethal and lethal TBI in mice[3].
GT3-Nano (50 mg/kg; i.v.; ) can facilitate rapid recovery of hematopoietic components in mice treated with the endoradiotherapeutic agent 153Sm-EDTMP[3].
| Animal Model: | C57/BL6 mice (6-8 weeks old) treated with the whole-body irradiation[3] |
| Dosage: | 16, 24, 32, and 50 mg/kg |
| Administration: | Intravenous injection; observed mice for 100 days |
| Result: | Demonstrated dose-dependent radioprotection, achieving 90% survival at 50 mg/kg against lethal 9-Gy of total-body irradiation (TBI). And upregulated progenitor bone marrow cells MPP2 and CMP in GT3-Nano-treated mice. |
