General description
L-(+)-麦角硫因(ET)是一种含硫氨基酸,仅由担子菌科和子囊菌科的放线菌和非酵母类真菌产生。它最初是从紫麦角菌或黑麦麦角菌中分离出来的。它是从L-组氨酸中获得的,该组氨酸被转化为甜菜碱形式,称为组氨酸甜菜碱。它存在于动物和植物中,哺乳动物通常从它们的饮食中获取,例如通过蘑菇或燕麦。它的性质是互变异构的,在中性水溶液中以硫酮形式存在。
研究领域:细胞凋亡
研究领域:细胞凋亡
Application
L-(+)-麦角硫因适用于研究它与2,2′- 和4,4′-联吡啶二硫化物(2-Py-S-S-2-Py和4-Py-S-S-4-Py)的反应性。它也可用于实验细胞的孵育,同时进行ATM(Ataxia毛细血管扩张症突变)或ATR (ATM-和RAD3-相关)的体外激酶活性测定。
L-(+)-麦角硫因已被用于:
L-(+)-麦角硫因已被用于:
- 作为卵丘-卵母细胞复合物(COC)成熟培养基的组成部分,检测其对脂质过氧化形成的保护作用
- 作为一种抗氧化化合物用于检测2型糖尿病患者
- 作为可溶性载体蛋白22A4 (SLC22A4)转运检测的阳性对照
Biochem/physiol Actions
L-(+)-麦角硫因(ET)在氧化应激组织中浓度最高,在血液、晶状体、骨髓、精液和肝脏中浓度最高。它是一种抗氧化剂,通过清除活性氧和活性氮,防止细胞凋亡。抗氧化活性主要来源于巯基。它是SLC22A4(溶质载体族22,成员4)转运体的底物。在肺泡巨噬细胞中,阻止肿瘤坏死因子(TNF)α释放白细胞介素-8 (IL-8)。IL-8是一种炎性细胞因子。它还能调节肝、肾的氧化损伤,并对脂质过氧化有保护作用。它还负责内源性谷胱甘肽和α-生育酚的保存。ET是一种抗氧化剂,可以抵御γ和紫外线辐射。在紫外线照射的人皮肤成纤维细胞中,它可以清除活性氧(ROS),并抑制基质金属蛋白酶1 (MMP1)的表达。它还可能防止紫外线辐射引起的皮肤衰老。
Packaging
