美他多辛最早由意大利LABORATORI BALDACCI S.P.A.公司研制開發(fā),臨床主要用于急、慢性酒精中毒和酒精性脂肪肝的治療,也被認為可以有效的戒酒,減少對酒精的依賴,改善記憶功能,特別是短時記憶。
將22.68g L-焦谷氨酸(0.176mol)與29.70g維生素B6堿(0.176mol)混合均勻,此過程中沒有發(fā)粘,一直為干粉狀。將此混合粉末放入150ml反應瓶中,然后攪拌下加入40ml異丙醇,異丙醇中含有1.5ml去離子水(其中異丙醇的比重 為0.7851),35℃水浴下攪拌2小時,保溫35℃靜置15小時。然后過濾,將所得白色固體在35℃下真空干燥4小時,研細,過80目篩,再在35℃下真空干燥5 小時,即得45.00g白色固體,產(chǎn)物為美他多辛,收率為85.9%。
Simultaneous Metadoxine treatment notably inhibits adipogenic differentiation in a dose-dependent manner. Metadoxine treatment from day 4 through day 8 is required for inhibition of MDI-induced preadipocyte differentiation. Metadoxine prevents glutathione depletion and the increase in lipid peroxidation damage caused by ethanol and acetaldehyde in HepG2 cells. In hepatic stellate cells, Metadoxine prevents the increase in collagen and attenuated TNF-α secretion caused by acetaldehyde. Thus, Metadoxine could be useful in preventing the damage produced in early stages of alcoholic liver disease as it prevents the redox imbalance of the hepatocytes and prevents TNF-α induction, one of the earliest events in hepatic damage.
