RESUMO
A strategy combining collision cross section(CCS) prediction and quantitative structure-retention relationship(QSRR) model for quinoline and isoquinoline alkaloids was established based on UHPLC-IM-Q-TOF-MS and applied to Phellodendri Chinensis Cortex and Phellodendri Amurensis Cortex. The strategy included the following three steps.(1) The molecular features were extracted by the "find features" algorithm.(2) The potential quinoline and isoquinoline alkaloids were screened by filtering the original characteristic ions extracted from Phellodendri Chinensis Cortex and Phellodendri Amurensis Cortex by the established CCS vs m/z prediction interval.(3) According to the retention time of candidate compounds predicted by QSRR model, the chemical constituents were identified in combination with the characteristic fragment ions and pyrolysis law of secondary mass spectrometry. With the strategy, a total of 80 compounds were predicted, and 15 were identified accurately. The strategy is effective for the identification of small analogs of traditional Chinese medicine.

Saposhnikovia divaricata (Turcz.) Schischk (S. divaricata, Fangfeng) is a herb in the Apiaceae family, and its root has been used since the Western Han Dynasty (202 B.C.). Chromones and coumarins are the pharmacologically active substances in S. divaricata. Modern phytochemical and pharmacological studies have demonstrated their antipyretic, analgesic, anti-inflammatory, antioxidant, anti-tumor, and anticoagulant activities. Technological and analytical strategy theory advancements have yielded novel results; however, most investigations have been limited to the main active substances-chromones and coumarins. Hence, we reviewed studies related to the chemical composition and pharmacological activity of S. divaricata, analyzed the developing trends and challenges, and proposed that research should focus on components' synergistic effects. We also suggested that, the structure-effect relationship should be prioritized in advanced research.

The chemical complexity of traditional Chinese medicines (TCMs) makes the active and functional annotation of natural compounds challenging. Herein, we developed the TCMs-Compounds Functional Annotation platform (TCMs-CFA) for large-scale predicting active compounds with potential mechanisms from TCM complex system, without isolating and activity testing every single compound one by one. The platform was established based on the integration of TCMs knowledge base, chemome profiling, and high-content imaging. It mainly included: (1) selection of herbal drugs of target based on TCMs knowledge base; (2) chemome profiling of TCMs extract library by LC‒MS; (3) cytological profiling of TCMs extract library by high-content cell-based imaging; (4) active compounds discovery by combining each mass signal and multi-parametric cell phenotypes; (5) construction of functional annotation map for predicting the potential mechanisms of lead compounds. In this stud TCMs with myocardial protection were applied as a case study, and validated for the feasibility and utility of the platform. Seven frequently used herbal drugs (Ginseng, etc.) were screened from 100,000 TCMs formulas for myocardial protection and subsequently prepared as a library of 700 extracts. By using TCMs-CFA platform, 81 lead compounds, including 10 novel bioactive ones, were quickly identified by correlating 8089 mass signals with 170,100 cytological parameters from an extract library. The TCMs-CFA platform described a new evidence-led tool for the rapid discovery process by data mining strategies, which is valuable for novel lead compounds from TCMs. All computations are done through Python and are publicly available on GitHub.

Lipids have been documented to play comprehensive and significant role in many biological processes. As a branch of metabolomics,lipidomics research mainly involves the analysis of the variation of lipid metabolism profiles under different physiologic,pathologic conditions or drug intervention,the discovery of key lipid biomarkers of a disease in lipid metabolic networks,and the study of the mechanism of action of lipid metabolic regulation during disease onset and progression,and drug treatment. Traditional Chinese medicines( TCMs)are characterized with integrated effects by multi-components,multi-targets and integrated effects. It is urgent to develop methods suitable for the study of complex TCMs to reveal the active constituents and integrated mechanism of action. Systems biology such as lipidomics provides valuable strategy and approach to illustrate the complex mechanisms of TCMs. In this paper,in order to provide technical references for TCMs,we have reviewed the analytical techniques applied in lipidomics and the applications of lipidomics in TCMs researches.

The study aims to analyze the mechanisms of Hirudo in promoting blood circulation and removing blood stasis based on network pharmacology. A database of chemical components of Hirudo was established through literature retrieval. The targets were predicted by using the reverse pharmacophore matching method and screened according to the antithrombotic and anticoagulant drug targets approved by FDA in the DrugBank database. Then, the targets were analyzed by KEGG pathway analysis, the protein interactions were analyzed by using BioGrid database, and the active constituents-target-pathway network model of Hirudo was established to study the mechanisms of Hirudo in promoting blood circulation and removing blood stasis. This study collected 49 chemical components of Hirudo, including amino acid, polypeptide, fatty acid ester, alkaloid, glycosides, and steroid. Totally 376 targets were predicted, and 5 critical targets related to the effects of Hirudo in promoting blood circulation and removing blood stasis were screened, including fibrinogen gamma chain, plasminogen, prothrombin, Urokinase-type plasminogen activator and coagulation factor X. The potential regulatory pathways included complement and coagulation cascades, platelet activation, VEGF signaling pathway, focal adhesion. This study reflects the multi-component, multi-target and multi-pathway features of Hirudo, and provides a scientific basis for elucidating the mechanisms of action of Hirudo in promoting blood circulation and removing blood stasis, as well as a reference for the study of mechanisms of traditional Chinese medicine.
RESUMO
OBJECTIVE: To observe the effects of red yeast rice (RYR) on blood lipid levels, aortic atherosclerosis (AS), and plaque stability in apolipoprotein E gene knockout (ApoE-/-) mice. METHODS: Twenty-four ApoE-/- mice were fed with a high-fat diet starting from 6 weeks of age. Mice were randomized into three groups (n = 8 in each group): model group (ApoE-/- group), RYR group (ApoE-/- + RYR group), and simvastatin group (ApoE-/- + simvastatin group). Eight 6-week-old C57BL/6 mice were assigned as the control group and fed with a basic diet. After 36 weeks, plasma lipids and inflflammatory factors were measured. Aortic atherosclerotic lesions by microscope, scanning electron microscope and transmission electron microscope were observed. Plasma levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were measured with enzyme-linked immunosorbent assay. The level of high sensitivity C-reaction protein (Hs-CRP) was detected by the scattering immunoturbidimetric assay. Protein expression of matrix metalloproteinase-9 (MMP-9) and nuclear factor κB (NF-κB) in aorta were tested by immunohistochemistry. RESULTS: Compared with the model group, treatment with RYR significantly decreased the levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol, lipoprotein (a), and apolipoprotein B100 in ApoE-/- mice (P<0.01). Compared with the model group, treatment with RYR decreased the levels of Hs-CRP, IL-6, and TNF-α (P<0.01). RYR also reduced the protein levels of NF-κB and MMP-9 of the aorta. CONCLUSIONS: RYR has the anti-atherosclerotic and stabilizing unstable plaque effects. The mechanism might be related to the inflflammatory signaling pathways.

Aristolochiae Fructus, a Chinese herbal medicine derived from the fruit of Aristolochia contorta Bge., contains nephrotoxic aristolochic acid analogues (AAAs). According to ancient medical texts, various medicinal parts of the fruit of A. contorta were ever used. In order to reveal which part could be safely and effectively used, it is necessary to analyze the chemical profiles of different medicinal parts. Herein we compared the chemical compositions and determined aristolochic acid I (AA-I) and aristolochic acid II (AA-II) in the four parts viz. outer pericarp, inner pericarp, septum, and seed. Ultra-high performance liquid chromatography equipped with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS) was applied for chemical profiling. Ultra-high performance liquid coupled with triple quadrupole mass spectrometry (UHPLC-QqQ-MS) was employed to quantify AA-I and AA-II in different parts. It was found that the chemical compositions of the four parts varied both qualitatively and quantitatively. A total of 10 AAAs, including 5 aristolochic acids and 5 aristolactams, together with 3 alkaloids, were unambiguously or tentatively identified by UHPLC-QTOF-MS. The quantitatively analytical results obtained by UHPLC-QqQ-MS showed that AA-I and AA-II exclusively accumulate in the seeds of A. contorta. These findings provide supporting data for the rational selection of medicinal parts.

ETHNOPHARMACOLOGICAL RELEVANCE: The pericarp of Citrus reticulata possesses medical functions of regulating Qi and expelling phlegm, and has been clinically used for the treatment of lung related diseases in traditional Chinese medicine for a long time. Our previous research revealed that Citrus reticulata exhibited inhibitory effects on pulmonary fibrosis; however, its active principles are still unclear. AIM OF THE STUDY: To investigate the inhibitory effects on pulmonary fibrosis of alkaline extract from ethanol extract of Citrus reticulata and clarify its possible mechanism. MATERIALS AND METHODS: The citrus alkaline extract (CAE) was prepared from ethanol extract of Citrus reticulata and MRC-5 cells were used for the evaluation of inhibitory activity in vitro. CAE was further orally administrated to bleomycin (BLM)-induced pulmonary fibrosis rats. The rat body weight, hydroxyproline levels in serum and lung, pathological changes of lung, as well as mRNA and protein expressions of matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1) and tumor necrosis factor-α (TNF-α) in rat lung tissues were analyzed. RESULTS: CAE dose-dependently inhibited the proliferation of MRC-5 cells, and the LDH assay clearly revealed that the inhibitory activity of CAE was not due to its cytotoxicity. CAE treatment significantly increased rat weight gain, ameliorated alveolitis and pulmonary fibrosis degree, and lowered hydroxyproline contents in both serum and lung tissues. RT-PCR and western blot revealed that mRNA and protein expressions of MMP-9 were significantly elevated, while mRNA and protein levels of TIMP-1 and TNF-α were markedly decreased in lung tissues of CAE treated rats. CONCLUSIONS: The results collectively demonstrated that CAE possessed an inhibitory activity on the proliferation of MRC-5 and a preventive effect on BLM-induced pulmonary fibrosis in rats. The preliminary mechanisms of the effects may be through upregulation of MMP-9 expression and inhibition of the expressions of TNF-α and TIMP-1.
