Precise discovery of a STAT3 inhibitor from Eupatorium lindleyanum and evaluation of its activity of anti-triple-negative breast cancer

Nat Prod Res 2019 Feb;33(4):477-485.PMID:29086600DOI:10.1080/14786419.2017.1396596.

Michael reaction acceptors (MRAs) are a class of active compounds. There is a great prospect to screen STAT3 inhibitors from Eupatorium lindleyanum, furthermore, to discover lead compounds for anti-triple-negative breast cancer (TNBC). In this study, glutathione (GSH) was employed, and a UPLC-MS screening method was developed to discover MRAs. We screened MRAs which can inhibit STAT3 using a STAT3-dependent reporter system. Six sesquiterpene lactones, including a new compound Eupalinolide O (1), together with five known compounds, Eupalinolide I (2), Eupalinolide K (3), Eupalinolide H (4), Eupalinolide J (5) and Eupalinolide G (6) were isolated. Eupalinolide J was identified as MRA that decreased luciferase activity of STAT3. Preliminary activity assessment showed that Eupalinolide J could inhibit the viability of TNBC cell lines. We demonstrated that Eupalinolide J, which is a natural typical MRA, has a notable inhibition of STAT3 activity and a potential cytotoxic activity against TNBC cell lines.

[Research on Q-markers of Eupatorium lindleyanum based on analytic hierarchy process-entropy weight method and network pharmacology]

Zhongguo Zhong Yao Za Zhi 2021 Nov;46(21):5545-5554.PMID:34951205DOI:10.19540/j.cnki.cjcmm.20210813.201.

The potential quality markers( Q-markers) of Eupatorium lindleyanum were studied with analytic hierarchy process(AHP)-entropy weight method(EWM) and network pharmacological method. Based on the concept of Q-markers of traditional Chinese medicine, AHP-EWM was employed to quantitatively identify the Q-markers of E. lindleyanum. AHP method was applied to the weight analysis of the validity, testability, and specificity of the first-level indexes, and EWM method was used to analyze the secondlevel indexes supported by literature and experimental data. At the same time, based on the theory and method of network pharmacology, the component-target-disease-efficacy network of E. lindleyanum was built, and the components most closely related to the efficacy of resolving phlegm and relieving cough and asthma were screened out. Through the integrated analysis of the results obtained with AHP-EWM and network pharmacological method, 13 compounds including rutin, quercetin, nepetin, cirsiliol, luteolin, hyperoside,isoquercitrin, kaempferol, caffeic acid, Eupalinolide K, eupalinolide A, eupalinolide B, and eupalinolide C were comprehensively identified as the potential Q-markers of E. lindleyanum. The results provide a basis for the quality control of E. lindleyanum.
