尿酸 用途与合成方法

简介

尿酸是嘌呤代谢的终末产物，体内总尿酸的80%由细胞核蛋白分解代谢产生，20%由摄入富含嘌呤的食物分解代谢产生。尿酸基本上以尿酸单钠盐的游离态形式存在于血液中，因此也称为血尿酸。

生物活性

Uric acid 是一种内源性抗氧化剂，可清除活性氧类化合物 (ROS)，包括单线态氧，氧自由基和过氧亚硝酸盐。

靶点

体外研究

Uric acid is an endogenous antioxidant that scavenges reactive oxygen species (ROS) including singlet oxygen, oxygen radicals, and peroxynitrite. Incubation with indomethacin significantly increases malondialdehyde (MDA) levels in Caco-2 cells compare to those not treated indomethacin. Incubation with both indomethacin and Uric acid significantly decreases MDA levels compare to those grown in the presence of indomethacin alone. Co-treatment of cells with indomethacin and Uric acid significantly decreases ROS levels compare to those in cells incubated with indomethacin alone. Cell viability in Caco-2 cells treated with both indomethacin and Uric acid is higher than that in cells treated with indomethacin alone. Uric acid has a protective effect on indomethacin-induced intestinal cell changes through its antioxidant activity.

体内研究

When mice treated with indomethacin are concurrently administered Uric acid orally, ulcer areas are significantly reduced, in a Uric acid dose-dependent manner. Indomethacin increases the ratio of crypt depth to villous height in the ileum, while the ratio is significantly lower when mice are concurrently administered Uric acid orally. Administration of indomethacin also increases the histopathological score of tissue damage in the small intestine, while mice concurrently administered Uric acid orally has a significantly lower histopathological score. The ileal levels of malondialdehyde (MDA) in indomethacin-induced enteropathy model mice orally administered Uric acid are also significantly lower than the levels in mice administered indomethacin alone.

用途 

用作分析试剂，也用于有机合成

用途 

用作测定尿酸的标准液

生产方法 

1.取干燥鸡粪悬浮于24倍量水中，加入适量氢氧化钙后静置。沉淀完全后分出上清液，沉淀中再加水，用硝酸调节pH值至3，静置至沉淀完全。分出上清液，沉淀物再悬浮在水中，以氢氧化钙调节pH值至12～12.5，过滤后滤液以硝酸调pH值至3，析出物过滤、干燥后即为尿酸粗品。
