Abstract

Acetaminophen (APAP) is a widely used analgesic and antipyretic over-the-counter medicine worldwide. Hepatotoxicity caused by APAP overdose is one of the leading causes of acute liver failure (ALF) in the US and in some parts of Europe, limiting its clinical application. Excessive APAP metabolism depletes glutathione and increases N-acetyl-p-benzoquinoneimide (NAPQI) levels, leading to oxidative stress, DNA damage, and cell necrosis in the liver, which in turn leads to liver damage. Studies have shown that natural products such as polyphenols, terpenes, anthraquinones, and sulforaphane can activate the hepatocyte antioxidant defense system with Nrf2 as the core player, reduce oxidative stress damage, and protect the liver. As the key enzyme metabolizing APAP into NAPQI, cytochrome P450 enzymes are also considered to be intriguing target for the treatment of APAP-induced liver injury. Here, we systematically review the hepatoprotective activity and molecular mechanisms of the natural products that are found to counteract the hepatotoxicity caused by APAP, providing reference information for future preclinical and clinical trials of such natural products.

摘要

对乙酰氨基酚(APAP)是一种在全球范围内广泛使用的非处方止痛和解热药物。在美国和欧洲部分地区,APAP过量导致的肝毒性是急性肝衰竭(ALF)的主要原因之一,限制了其临床应用。过量的APAP代谢会耗尽谷胱甘肽并增加N-乙酰对苯醌亚胺(NAPQI)水平,导致氧化应激、DNA损伤和肝脏细胞坏死,进而导致肝损伤。研究表明,多酚、萜类、蒽醌和萝卜硫素等天然产物可以激活以Nrf2为核心的肝细胞抗氧化防御系统,减少氧化应激损伤并保护肝脏。作为将APAP代谢为NAPQI的关键酶,细胞色素P450酶也被认为是治疗APAP诱导的肝损伤的有趣靶点。在此,我们系统地综述了已发现的可对抗APAP所致肝毒性的天然产物的肝脏保护活性和分子机制,为这类天然产物未来的临床前和临床试验提供参考信息。
