Lemairamin
Based on 1 Customer Validation
Lemairamin (Wgx-50) is a hydroxylamine compound. Lemairamin can be isolated from the pericarps of the Zanthoxylum plants. Lemairamin activates α7nAChR, stimulates the expression of IL-10 and POMC. Lemairamin shows a decrease in Akt. Lemairamin attenuates DSS-induced intestinal inflammation. Lemairamin alleviates pain hypersensitivity.

Lemairamin (1-300 mg/kg; s.c.) dose-dependently inhibits formalin-induced tonic pain in male Swiss mice with an Emax of 66.7% inhibition and an ED50 of 11.1 mg/kg, via activation of α7nAChRs[2].
Lemairamin (1-300 mg/kg; s.c.; single administration) dose-dependently inhibits formalin-induced tonic pain in adult Wistar rats with an Emax of 45.9% inhibition and an ED50 of 21.9 mg/kg[2].
Lemairamin (10-300 μg; i.t.; single administration) dose-dependently reduces mechanical allodynia in L5/L6 spinal nerve ligated Wistar rats with an Emax of 60.4% MPE and an ED50 of 83.9 μg, via α7nAChR activation and subsequent stimulation of spinal IL-10 and β-endorphin expression[2].

Result:Suppressed recruitment of neutrophils to the intestinal injury site, with the most significant reduction observed at 12 hours.
Significantly reduced the relative mRNA expression levels of pro-inflammatory cytokines il-1β, il-6, cxcl8a, and tnf-α, with the most significant reduction at 12 hours.
Preserved intestinal morphology, including intact, well-arranged intestinal epithelial cell structure, normal glandular structure, reduced intestinal vacuoles, alleviated DSS-induced increases in crypt depth, and restored the villus length to crypt depth ratio.
Significantly decreased the relative protein expression of p-Akt/Akt compared to the DSS-only group.
Significantly downregulated the relative mRNA expression levels of akt1, akt2, and akt3, which were upregulated by DSS treatment.

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (321.16 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (8.03 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.
