Gaultherin
Based on 1 Customer Validation
Gaultherin is an orally active non-steroidal anti-inflammatory agent. Gaultherin selectively inhibits NF-κB, MAPK, COX-2 (IC50 = 0.35 mg/mL), LOX (IC50 = 0.56 mg/mL) and HYAL (IC50 = 28.58 μg/mL) to exert anti-inflammatory, antipyretic and analgesic effects. Gaultherin exhibits modest direct antioxidant capacity, greater in cell-based models. Gaultherin does not affect COX-1 so that avoids the common gastrointestinal side effects of Aspirin (HY-14654).

Gaultherin acts only after it is transformed into methyl salicylate by intestinal bacteria and then the absorbed methyl salicylate is hydrolyzed rapidly by esterases in intestine, blood and liver to produce salicylate[1].
.
Gaultherin presents low antioxidant activity, ferric reducing activity, and scavenging potential towards O2•− with SC50s of 265.69 μg/mL (DPPH), 0.64 mmol Fe²⁺/g (FRAP), 451.76 μg/mL (O2•−), 488.52 μg/mL (•OH), 587.86 μg/mL (H2O2)[2].
Gaultherin (25-75 μM) significantly inhibits the secretion of ROS in fMLP (HY-P0224)-stimulated human neutrophils and LPS (HY-D1056)-stimulated RAW264.7 murine macrophages[2].
Gaultherin inhibits the release of pro-inflammatory cytokines including IL-8, IL-1β, TNF-α, MMP-9 and ELA-2 in LPS/fMLP + Cytochalasin B (HY-16928)-stimulated human neutrophils and NO, TNF-α, IL-1β and IL-6 in LPS-stimulated RAW264.7 murine macrophages[2].
Gaultherin prevents phosphorylation and subsequent degradation of IκBα and blocks the translocation of NF-κB to the nucleus[2].
Gaultherin inhibits directly or via upstream modulation of MAPK kinases, particularly MEK1/2, MKK3/6, and MKK4/7, and thus suppresses the phosphorylation/activation of MAPKs, including JNKs, p38, and ERKs[2].

Gaultherin (400 mg/kg, p,o., once daily for 3 days) significantly inhibits the ear swelling after the application of croton oil[1].
Gaultherin (330 mg/kg, p,o., single dose) does not aggravate the stress-induced gastric damage and is significantly superior to Aspirin[1].
Gaultherin (100-300 mg/kg, p,o., single dose) induces a reduction in rectal temperature in feverish mice[2].

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 (5.60 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.
