Ligustrazine
Based on 11 publication(s) in Google Scholar
Ligustrazine (Chuanxiongzine) is an orally active, blood-brain barrier-permeable alkaloid. It can be isolated from Ligusticum striatum DC. Ligustrazine reduces ROS, upregulates the levels of p-Akt/Akt and p-eNOS/eNOS, and decreases ALT and AST. It inhibits glutamate excitotoxicity, calcium overload, oxidative stress, ischemia-reperfusion injury and atherosclerotic plaque progression, enhances synaptic plasticity, and improves neurological function, cerebral infarct volume and brain water content. Ligustrazine possesses anti-inflammatory, antioxidant, lipid-lowering, endothelial protective and hepatoprotective activities. It can be used in studies related to ischemic stroke, cerebral ischemia-reperfusion injury and atherosclerosis.

Ligustrazine (1-100 μM) dose-dependently increases NO production in OGD-treated human amniotic epithelial cells by activating the PI3K/Akt pathway, with no significant effect on NO production in normal HAECs[2].
Ligustrazine (0.1-10 μM) dose-dependently increases p-Akt/Akt and p-eNOS/eNOS in OGD-treated human amniotic epithelial cells by activating the PI3K/Akt pathway, with no significant effect on these factors in normal HAECs[2].
Ligustrazine protects endothelial cells against LDL-induced damage in an in vitro cell-based system[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Ligustrazine (20 mg/kg; i.p.; 15 min after model establishment) improves neurological function in male C57BL/6 mouse models of ischemic stroke[1].
Ligustrazine (1-10 mg/kg; i.p.; administered once at 2 h and 12 h post-operation) protects Wistar rats against cerebral ischemia-reperfusion injury in a dose-dependent manner by activating the PI3K/Akt pathway, which increases the levels of p-Akt and p-eNOS, improves neurological function, and alleviates brain tissue damage[2].
Ligustrazine (20-80 mg/kg; p.o.; 6 weeks) dose-dependently inhibits the progression of atherosclerosis and hepatic lipid accumulation in Sprague-Dawley rats, with the daily oral dose of 80 mg/kg reducing the aortic lesion area by 49.0% compared with the untreated atherosclerotic control group[3].

Ligustrazine (TMP, 25-100 mg/kg; i.p.; once daily for 7 days) can ameliorate liver injury in septic mice: Pathological changes in liver tissues of mice in each group, yellow arrows: hepatic cords; black arrows: hepatocytes. H&E staining results showed that in the Sham group, the liver tissues were structurally intact and morphologically normal, with no cell necrosis; in the CLP group, hepatocytes were swollen and necrotic, and hepatic cords were disorganized, accompanied by extensive inflammatory cell infiltration; compared with the CLP group, liver tissue damage in the CLP + XBJ, CLP + TMP L (25 mg/kg), CLP + TMP M (50 mg/kg), and CLP + TMP H (100 mg/kg) groups was significantly improved, hepatic cord structure was restored, and inflammatory cell infiltration was reduced, with the most significant improvement in the CLP + XBJ and CLP + TMP H groups.

- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (18.36 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (18.36 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
