ABSTRACT
Artemisia capillaris Thunb. (A. capillaris) is a well-known traditional Chinese herbal medicine with a wide range of pharmacological effects, such as soothing the liver and gallbladder, heat clearance, and detoxifying. Hence, its extract is commonly added to various traditional Chinese medicine formulas. Traditional Chinese medicine injection (TCMI) is a mature pharmaceutical dosage form developed using TCM theory combined with modern science and technology. Notably, allergic reactions, especially pseudoallergic reactions (PARs), greatly limited the use of these injections. Therefore, screening pseudoallergic components in A. capillaris extract is clinically significant. In the present study, we proposed a two-dimensional screening and identification system based on mas-related G protein-coupled receptor X2-HALO-tag/cell membrane chromatography (MrgX2-HALO-tag/CMC) high performance liquid chromatography mass spectrometry (HPLC-MS); seven potential active components were screened from 75 % ethanol extract of A. capillaris NCA, CA, CCA, 1,3-diCQA, ICA-B, ICA-A, and ICA-C. The receptor-ligand interactions between these seven compounds and MrgX2 protein were analyzed using frontal analysis and molecular docking technology. Furthermore, a mast cell degranulation-related assay was used to assess the pseudoallergic activity of these compounds. The screened compounds can serve as ligands of MrgX2, and this study provides a research basis for pseudoallergic reactions caused by TCMIs containing A. capillaris.
