Ethnopharmacological Relevance:
Lanqin Oral Liquid (LQL) is a pure herbal preparation with a good therapeutic effect on acute pharyngitis in clinic. However, its active ingredients and action mechanisms need further research.
Aims Of The Study:
This work employed network pharmacology to uncover the bioactive equivalent combinatorial components (BECCs) of LQL and investigate their mechanisms in treating acute pharyngitis.
Materials And Methods:
In this study, a component-disease-target (C-D-T) network related to LQL and pharyngitis was constructed through network pharmacology and candidate BECCs were found based on the degree values of each node in the C-D-T network. The anti-acute pharyngitis effects between BECCs and LQL were evaluated by animal and cell experiments, and the vital signaling pathways predicted by network pharmacology were verified. Additionally, the synergistic effect of berberine (BBR) and geniposide (GE), the core active ingredients of BECCs, was further explored by the combination index (CI) method.
Results:
Network pharmacology indicated that 25 potential active ingredients in LQL and 35 targets were involved in the treatment of acute pharyngitis, covering 20 signaling pathways. Based on network pharmacology degree values, 13 compounds were identified as BECCs. In vitro and in vivo studies revealed that BECCs exhibit comparable therapeutic efficacy to LQL in treating acute pharyngitis. BECCs could treat acute pharyngitis by reducing the release of NO, secretion of inflammatory factors (IL-6, IL-1β, and TNF-α), and expression of related proteins (TLR4 and p-p65). Notably, BBR and GE emerged as BECCs' most effective components, demonstrating significant anti-inflammatory synergy.
Conclusion:
BECCs of LQL demonstrate comparable efficacy against acute pharyngitis to the original formula, which may exert anti-inflammatory effects by regulating the TLR4/NF-κB signaling pathway. The diverse components in BECCs potentially exhibit synergistic pharmacological effects. These findings provide a solid scientific foundation for the clinical application of LQL.

01:30Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
