ABSTRACT
As a commonly used traditional Chinese medicine in clinical practice, Tripterygium wilfordii has the functions of dispelling wind and removing dampness, detoxicating and destroying parasites, detumescence, pain relief, promoting blood circulation, and dredging collateral. Modern pharmacological studies show that it also has other functions such as anticancer, anti-inflammation, and immunosuppression. It has been widely used to treat autoimmune diseases, renal diseases, and tumors. T. wilfordii contains a variety of chemical components, among which triptolide (TP) can cause varying degrees of damage to human digestive, circulatory, reproductive, and other systems, with liver injury being the most common one, which greatly limits the development of TP in new drug research and industrial application. Therefore, the authors focused on the research hotspot of TP-induced liver injury and summarized relevant Chinese and international literature regarding the clinical manifestations, injury mechanisms, and detoxification strategies of TP-induced liver injury. This helps to provide a scientific basis for the clinical drug safety and scientific drug supervision of TP. The clinical manifestations of TP-induced liver injury are mostly abnormal transaminases, loss of appetite, nausea and vomiting, anorexia, yellow staining of skin and sclera, and yellow urine. The mechanisms of the above clinical manifestations involve apoptosis, oxidative stress, influence on cytochrome P450 superfamily, macrophage polarization, regulation of biological clock gene Clock, etc. Among them, cell apoptosis is related to neurogenic locus notch homolog protein 1 (Notch1), dynamin-related protein 1 (Drp1)-cytochrome C (Cyt C), phosphatidylinositide 3-kinases (PI3K)/protein kinase B (Akt), mitogen-activated protein kinase (MAPK), tumor suppressor protein 53 (p53), Fas cell surface death receptor (Fas)/Caspase-8, and other signaling pathways. Oxidative stress is related to inhibition of nuclear factor-erythroid 2-related factor 2 (NRF2) signaling pathway, promotion of cytochrome P450 2E1 (CYP2E1) expression, and excessive accumulation of reactive oxygen (ROS). The influence of the cytochrome P450 superfamily is manifested as reducing the substrate affinity, activity, and expression of cytochrome P450 3A (CYP3A), cytochrome P450 2C9 (CYP2C9), cytochrome P450 2C19 (CYP2C19), and cytochrome P450 1A2 (CYP1A2). Promoting the transformation of macrophages into the M1 type is related to the secretion of inflammatory factors and the accumulation of endotoxin, and the internal rhythmic regulation of the biological clock gene Clock, is related to the expression of cytochrome P450 3A11 (CYP3A11) metabolic enzyme. The detoxification strategies in the clinical application include herbs-processing detoxification strategy and drug-pairing detoxification. The traditional Chinese medicines and monomers that are helpful for detoxification include Glycyrrhiza uralensis, Paeonia lactiflora, Lysimachia christinae, Rehmannia glutinosa, saffron, and paeoniflorin. The reviews and discussion about these topics can help to provide more references for related research and clinical application of TP.
