RESUMEN

The aim is to investigate the potential allergens and mechanisms underlying allergic-like reactions induced by Danshen injection (DSI). Utilizing ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS), metabolomics, and bioinformatics, we identified the key allergens, targets, and metabolic pathways involved in DSI-induced allergic-like reactions, validating binding efficiency through molecular docking and molecular dynamics. A total of 45 compounds were identified within DSI, with 24 compounds exhibiting strong binding activity to the MrgprX2 activation site. DSI was found to cause changes in 89 endogenous metabolites, including arachidonic acid, prostaglandins, and leukotrienes, primarily affecting pathways such as phenylalanine metabolism and arachidonic acid metabolism. The key allergens identified were Cryptotanshinone, Miltipolone, Neocryptotanshinone, Salvianolic acid B, and Isosalvianolic acid C, which primarily trigger allergic-like reactions by regulating upstream signaling targets such as ALOX5, PTGS1, PPARD, and LTB4R. Validation confirmed the high binding affinity and stability between key allergens and targets. These findings indicate that the allergic components in DSI primarily induce allergic-like reactions by modulating the aforementioned signaling targets, activating the AA metabolic pathway, promoting mast cell degranulation, and releasing downstream endogenous inflammatory mediators, subsequently eliciting allergic-like reactions.

RESUMEN

ObjectiveTo perform a predictive analysis of the quality marker(Q-Marker) for the anticoagulant activity of Kunning granules. MethodThe chemical components of Kunning granules were analyzed by ultra high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry(UHPLC-Q-TOF-MS/MS) on a Waters ACQUITY UPLC HSS T3 column(2.1 mm×100 mm, 1.8 μm) with the mobile phase of acetonitrile(A)-25 mmol∙L-1 ammonium acetate aqueous solution(B) for gradient elution (0-5 min, 5%-22%A; 5-10 min, 22%-30%A; 10-15 min, 30%-95%A; 15-20 min, 95%-5%A; 20-30 min, 5%A), flow rate of 0.2 mL∙min-1, column temperature at 30 ℃, injection volume of 1 μL, electrospray ionization(ESI), positive and negative ion detection modes. Interaction analysis between the targets of chemical components and the targets of abnormal uterine bleeding(AUB) was performed by network pharmacology, and the key components were screened through network topology analysis. The fingerprints of 10 batches of Kunning granules were established by high performance liquid chromatography(HPLC), the anticoagulant activity of the granules was determined by blood coagulation method and fibrinogen plate method, and the spectrum-effective relationship was established. The components co-occurring in the topological analysis and spectrum-effective relationship were selected as Q-Markers, and their anticoagulant activities were verified and confirmed. ResultA total of 475 chemical components were identified from Kunning Granule, of which 22 key components such as salvianolic acid B, paeoniflorin, naringin and neohesperidin, were the potential material basis for the treatment of AUB. The spectrum-effective analysis showed that peaks 7(paeoniflorin), 9(naringin), 10(neohesperidin) and 11(salvianolic acid B) were the optimal principal components, and in vitro activity test showed that these four components could better characterize their anticoagulant activity. ConclusionSalvianolic acid B, paeoniflorin, neohesperidin and naringin may be Q-Markers for the anticoagulant activity of Kunning granules.
