: Ligustrazine purchased from MedChemExpress. Usage Cited in: Biochem Pharmacol. 2025 Jul 26:241:117193. [Abstract]; 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.

Images were taken at 40 × and 400 ×. HE staining revealed that Ligustrazine (TMP, 60 mg/kg; i.p.; once daily for 10 days) significantly ameliorated 5-FU (20 mg/kg; i.p.; once daily for 10 days)-induced cardiomyocyte disarray, inflammatory cell infiltration, and histological disruptions in BALB/c mice.

Ligustrazine (TMP, 12.5 μM; 48 h) treatment significantly reversed the reduction in cell density induced by 5-FU (10 μM; 48 h).

: Ligustrazine purchased from MedChemExpress. Usage Cited in: Eur J Pharmacol. 2025 Sep 17:178180. [Abstract]; Ligustrazine (TMP) (6.25-100 μM; 48 h) alone exhibited no cytotoxic effects on H9C2 cells. Co-treatment with TMP (12.5–50 μM; 48 h) significantly reversed the suppression of cell viability induced by 10 μM 5-FU.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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.

Protocol 1

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.
Protocol 2

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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (18.36 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.

Protocol 1

Add each solvent one by one: 0.5% CMC-Na/0.5% Tween-80 in Saline water
Solubility: 15.92 mg/mL (116.90 mM); Suspended solution; Need ultrasonic

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
