The chemical constituents of Chuanzhi Tongluo Capsules were analyzed and identified using ultra-high performance liquid chromatography-quadrupole/electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap-MS) to clarify the pharmacological substance basis. In addition, network pharmacology was employed to explore the mechanism of Chuanzhi Tongluo Capsules in the treatment of cerebral infarction. Gradient elution was performed using acetonitrile and 1% acetic acid in water as the mobile phase. Mass spectrometry was performed in positive and negative ion modes. Xcalibur 4.2 software was used for compound analysis, including accurate mass-to-charge ratio and MS/MS fragment information, combined with the comparison of reference standards and literature data. A total of 152 compounds were identified, including 32 organic acids, 35 flavonoids and their glycosides, 33 diterpenes, 13 phthalides, 12 triterpenes and triterpene saponins, 23 nitrogen-containing compounds, and 4 other compounds, and their fragmentation patterns were analyzed. SwissTargetPrediction, GeneCards, DAVID, and other databases were used to predict and analyze the core targets and mechanism of Chuanzhi Tongluo Capsules. Protein-protein interaction(PPI) network topology analysis identified 10 core targets, including TNF, VEGFA, EGFR, IL1B, and CTNNB1. KEGG enrichment analysis showed that Chuanzhi Tongluo Capsules mainly exerted their effects through the regulation of lipid and atherosclerosis, glycoproteins in cancer, MicroRNAs in cancer, fluid shear stress, and atherosclerosis-related pathways. Molecular docking was performed between the key constituents and core targets, and the results demonstrated a strong binding affinity between the key constituents of Chuanzhi Tongluo Capsules and the core targets. This study comprehensively elucidated the chemical constituents of Chuanzhi Tongluo Capsules and explored the core targets and mechanism in the treatment of cerebral infarction based on network pharmacology, providing a scientific reference for the study of the pharmacological substance basis and formulation quality standards of Chuanzhi Tongluo Capsules.

Network pharmacology study on the potential effect mechanism of Chuanzhi Tongluo Capsule in the treatment of cerebral infarction

Article

Author: Fan, Wenhui ; Ma, Shan ; Zhang, Jianxin

Background:Chuanxiong Tongluo capsules have been widely used to treat recovered stroke and cerebral infarction, but their specific therapeutic mechanism is not well understood.Methods:This study aims to investigate the mechanism of action for Chuanzhi Tongluo capsule on cerebral infarction based on a network pharmacology approach. The TCMSP platform collected the chemical composition of Chuanzhi Tongluo capsules. Its potential targets were predicted by Swiss target prediction and standardized using the Uniprot database for gene normalization. Meanwhile, the OMIM, Genecards, and TTD databases were used to obtain the targets related to cerebral infarction. The standard targets of Chuanzhi Tongluo capsule and cerebral infarction were uploaded to the STRING database to construct protein–protein interaction networks. Topological methods analyzed the key targets and components in the drug-component-disease-target network. Gene ontology function and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis of the shared targets were performed using the DAVID database.Results:A total of 105 active ingredients and 427 targets were associated with Chuanzhi Tongluo capsule, and there were 3055 targets related to cerebral infarction disease and 240 common targets between the two keywords. The key targets included INS, ALB, IL-6, VEGFA, TNF, and TP53. The conduction pathways involved include the calcium signaling pathway, cAMP signaling pathway, cGMP-PKG signaling pathway, and TNF signaling pathway.Conclusion:The active ingredients in Chuanzhi Tongluo capsule may participate in the therapeutic process of cerebral infarction by regulating the calcium, cAMP, cGMP-PKG, and TNF signaling pathway through critical targets such as INS, ALB, IL-6, VEGFA, TNF, and TP53.

[Chuanzhi Tongluo Capsules antagonizes cerebral ischemia-reperfusion injury in mice by inhibiting neuroinflammation and oxidative stress].

Article

Author: Fan, Jian-Wei ; Sun, Jing-Xia ; Zhang, Li ; Ku, Ya-Ping ; Zhang, Gui-Min ; Li, Bing

Chuanzhi Tongluo Capsules(CZTL) is effective in activating blood, resolving stasis, replenishing Qi, and dredging collaterals, which has been widely used in clinical treatment of stroke(cerebral infarction) differentiated into the syndrome of wind striking meridian and collateral in the recovery stage characterized by blood stasis and Qi deficiency. However, its modern pharmacological mechanisms of action remain unclear. This study duplicated the middle cerebral artery occlusion and reperfusion(MCAO/R) model in mice using the suture-occluded method to explore the protective effect and mechanism of CZTL on ischemic stroke. The mice were divided into the sham-operation group, model group, and CZTL group. The ones in the CZTL group were gavaged with 0.3 g·kg~(-1)·d~(-1) CZTL for three successive days. One hour after the last intragastric administration, those in the model and CZTL groups were subjected to MCAO/R. After 24 h reperfusion, the effects of CZTL on neurological deficit score, cerebral infarction area, brain edema, and brain histopathology were evaluated. The levels of reactive oxygen species(ROS), malondialdehyde(MDA), interleukin-6(IL-6), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α) and the activity of superoxide dismutase(SOD) in brain tissue homogenate were detected using corresponding assay kits. The expression of B-cell lymphoma-2(Bcl-2), Bcl-2-associated X protein(Bax), Toll like receptor 4(TLR4), and phosphorylated nuclear factor-κB P65 subunit(p-NF-κB P65) were assayed by Western blot. The results indicated that CZTL significantly reduced the neurological deficit score, brain edema, and infarct volume, improved the brain histopathology, inhibited the expression of ROS, MDA, IL-6, IL-1β, and TNF-α in the brain tissue, and up-regulated the activity of SOD, down-regulated the expression of pro-apoptotic protein Bax, promoted the expression of anti-apoptotic protein Bcl-2, and suppressed the expression of TLR4 and p-NF-κB P65 phosphorylation of MCAO/R mice. All these have demonstrated that CZTL has a significant protective effect against MCAO/R injury in mice, which may be related to its resistance to neuroinflammation and oxidative stress.
