中文名:氮氧自由基哌啶醇
英文名:4-Hydroxy-TEMPO
应用:4-羟基-TEMPO(HO-TEMPO)可用作催化剂将醇氧化成相应的醛。它可用于制备TEMPO聚合物催化体系,该体系可用于多种伯醇的Anelli氧化。它可以用作合成4-(2,2,6,6-四甲基-1-氧基-4-哌啶氧基)丁基溴的起始试剂。 用于研究生物化合物和聚合物的自旋标记物。 由衍生化TEMPO丙炔醚以及随后与氟叠氮化物发生"点击"反应,制备氟标记的TEMPO衍生物。该TEMPO衍生物已被证明是用漂白剂氧化醇的高效催化剂。 自旋标记试剂,用于鉴定 NK1 受体的拮抗剂和激动剂结合位点。也可用于电子自旋共振光谱法测定心肌中活性氧的生成。TEMPOL 可保护过量表达 CYP2E1 的细胞免受花生四烯酸的毒性损伤。

产品介绍:
TEMPOL is a superoxide dismutase mimetic that belongs to a class of non-thiol-containing radiation protectors, and has the ability to permeate the membrane. In the presence of TEMPOL, cerebral vessel remodeling is blocked and collagen IV mRNA expression levels are elevated in normotensive and hypertensive rat studies. TEMPOL has been shown to restore the oxidative stress and cardiac dysfunction induced by TNF-α and in PC-12 cells has revealed neuroprotective effects. Additionally, it has shown to decrease blood pressure and sympathetic nerve activity in DOCA-salt rat studies.
