Uric acid sodium
CAS No. : 1198-77-2
MCE 国际站:Uric acid sodium
产品活性:Uric acid sodium (Monosodium urate) 是氧自由基 (oxygen radical) 的清除剂,是一种非常重要的抗氧化剂,有助于维持血压的稳定和抗氧化应激。Uric acid sodium 能清除活性氧 (ROS),如单线态氧和过氧亚硝酸盐,抑制脂质过氧化。
研究领域:Immunology/Inflammation | NF-κB | Metabolic Enzyme/Protease
作用靶点:Reactive Oxygen Species | Endogenous Metabolite
In Vitro: Uric acid (400 μM; 48 hours) sodium protects Caco-2 cells from indomethacin-induced lipid peroxidation.
Co-treatment of cells with Indomethacin and Uric acid (200 μM IND plus 400 μM UA; 24 hours) sodium significantly decreases ROS levels compared to those in cells incubated with indomethacin alone. Cell viability in Caco-2 cells treated with both Indomethacin and Uric acid (200 μM IND plus 400 μM UA; 24 hours) sodium is higher than that in cells treated with indomethacin alone. Uric acid sodium has a protective effect on indomethacin-induced intestinal cell changes through its antioxidant activity.
In Vivo: Uric acid (250 mg/kg; p.o.) sodium ameliorates indomethacin-induced enteropathy.
Oral administration of uric acid sodium decreases ROS accumulation in the ileum in a mouse model of indomethacin-induced enteropathy.

文献和实验2, 6, 8-三羟基嘌呤。在酮型和烯醇型之间具有变构现象。是弱二元酸( pk1 =5.4, pk2 =10.6),微溶于水(约 0.0025%),几乎不溶于醇和醚。加热时也不熔化, 400℃以上时分解。是鸟类、陆生爬行类、昆虫类(双翅目除外)等作为氮代谢的主要的最终产物而排出。哺乳类的灵长类及软体动物的腹足类中排出的也很多,具有比较生物化学的意义(酶缺失现象)。痛风症患者的尿和血液中很多。蝴蝶的翅膀等也含有游离态的,而人和牛的红血球中可发现有 9-D-核苷形态的尿素物质。是嘌呤
Uric acid (UA), (7,9-dihydro-1H-purine-2, 6, 8 (3H)-trione), is the principal end product of purine metabolism (1 ); therefore, determinations of UA in biological samples can serve as a marker in detection of disorders associated with purine
蛋白变化等因素有关,感染引起结石时,尿中常出现磷酸镁铵的结晶。 2.草酸钙结晶(calciumoxalate crystals)为无色方形闪烁发光的八面体,有两条对角线互相交叉,有时呈菱形。不常见的形态为哑铃形或饼形,应与红细胞鉴别。结晶溶于盐酸但不溶于乙酸内,属正常代谢成分,但又是尿路结石主要之一。如草酸盐排出增多,患者临床表现尿路刺激症状(尿痛、尿频、尿急)或有肾绞痛合并血尿,则应注意患尿路结石症的楞能性,病人尿中偶尔可见到排出的结晶团。 3.尿酸结晶(uric acid
