產(chǎn)品詳情

詳細(xì)信息(中文):
α-硫辛酸是在1951年,美國(guó)科學(xué)家Reed等首次從豬肝中分離出來(lái)的具有活性的天然產(chǎn)物。其生理活性?xún)H局限于R 體,S體基本無(wú)活性,但也沒(méi)有毒副作用。α-硫辛酸屬于維生素B類(lèi)藥物。在臨床上α-硫辛酸用于治療神經(jīng)性糖尿病,缺血再灌注等疾病;另外α-硫辛酸對(duì)于肝病、老年癡呆、白內(nèi)障、心臟病等多種疾病有顯著的治療效果,并寫(xiě)能有效的抑制HIV-1在細(xì)胞中的擴(kuò)散。
α-硫辛酸是既具水溶性又具脂溶性的淡黃色晶體。目前仍處于右旋硫辛酸取代外消旋硫辛酸的過(guò)程之中。全世界的年需求量大概為400噸,并且正持續(xù)上漲,但產(chǎn)量?jī)H為200t左右。
現(xiàn)在普遍工業(yè)化的生產(chǎn)是用6,8-二氯辛酸乙酯為原料來(lái)合成α-硫辛酸,但是這個(gè)產(chǎn)品在夏天分子活躍,所以只能再冬天低溫的條件下生產(chǎn)。且污染很大,導(dǎo)致α-硫辛酸一直處于稀缺狀態(tài)。
α--硫辛酸別譽(yù)為“萬(wàn)能抗氧化劑”,它可以在體內(nèi)轉(zhuǎn)變成二氫硫辛酸(DHLA),硫辛酸和二氫硫辛酸都具有很強(qiáng)的抗氧化性。都能夠有效的清除自由基,預(yù)防體內(nèi)氧化應(yīng)激的反應(yīng)。
自由基誘導(dǎo)的氧化損傷長(zhǎng)期以來(lái)都被認(rèn)為是導(dǎo)致衰老發(fā)生的重要原因之一。所以α-硫辛酸可以通過(guò)消除自由基發(fā)揮抗衰老作用

詳細(xì)信息(英文):
Alpha-lipoic acid is an active natural product first isolated from pig liver by Reed et al., an American scientist in 1951. Its physiological activity is only limited to R body, S body is basically inactive, but there is no toxic side effect. Alpha-lipoic acid belongs to the B vitamin class. In clinic, alpha-lipoic acid is used to treat neurodiabetes, ischemia-reperfusion and other diseases. In addition, alpha-lipoic acid has a significant therapeutic effect on liver disease, senile dementia, cataract, heart disease and other diseases, and can effectively inhibit the spread of HIV-1 in cells.
Alpha-lipoic acid is a light yellow crystal that is both water-soluble and fat-soluble. It is still in the process of dextro-lipoic acid replacing racemic lipoic acid. The world's annual demand is around 400 tonnes and rising, but production is only around 200t.
The current industrial production of alpha-lipoic acid is based on ethyl 6, 8-dichloro-octyl acid, but this product is molecular-active in summer, so it can only be produced in winter at low temperatures. And pollution is so high that alpha-lipoic acid remains scarce.
Alpha-lipoic acid, also known as the "universal antioxidant," converts to DHLA in the body. Both lipoic acid and dihydrolipoic acid have strong antioxidant properties. Both can effectively eliminate free radicals and prevent the reaction of oxidative stress in the body.
Oxidative damage induced by free radicals has long been considered as one of the important causes of aging. So alpha-lipoic acid can play an anti-aging role by eliminating free radicals
