Senkyunolide I
Based on 1 Customer Validation
Senkyunolide I is an orally active, blood-brain barrier-permeable metabolite of Z-ligustilide (HY-N0401A). Senkyunolide I is isolated from Ligusticum chuanxiong. Senkyunolide I upregulates p-Erk1/2 and Nrf2/HO-1, and inhibits Caspase 3. Senkyunolide I alleviates Apoptosis. Senkyunolide I increases the pain threshold in mice and reduces acetic acid-induced writhing responses in mice. Senkyunolide I improves neurological deficits, reduces infarct volume and alleviates cerebral edema in rats with focal cerebral ischemia-reperfusion injury. Senkyunolide I protects renal function and structural integrity in a mouse model of renal ischemia-reperfusion injury. Senkyunolide I is applicable to research related to focal cerebral ischemia-reperfusion injury, migraine, and renal ischemia-reperfusion injury.

Senkyunolide I (25-100 μM) activates the Nrf2/ARE pathway in Hek293T/pGF1-ARE cells[1].
Senkyunolide I (100-300 μg/mL; prior to H2O2 treatment) protects the renal tubular epithelial cell line HK2 against H2O2-induced loss of viability[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Senkyunolide I (8-32 mg/kg; p.o.; single dose) dose-dependently increases thermal pain thresholds in mice, with the 32 mg/kg dose producing significant elevations as early as 20 min post-administration and the 16 mg/kg dose showing significant effects at 360 min post-administration[2].
Senkyunolide I (32 mg/kg; p.o.; single dose) significantly reduces acetic acid-induced visceral pain in mice, while lower doses show no significant effect[2].

vehicle) at both 36 mg/kg and 72 mg/kg, with no significant differences between the two doses.
Significantly increased the p-Erk1/2/t-Erk1/2 ratio, and the protein levels of c-Nrf2, n-Nrf2, HO-1, and NQO1 (P < 0.05 vs.
vehicle) at both 36 mg/kg and 72 mg/kg; resulted in higher levels of these proteins at 72 mg/kg compared to 36 mg/kg (P < 0.05).
Significantly reversed the down-regulation of Bcl-2 and up-regulation of Bax induced by I/R injury (P < 0.05 vs.
vehicle), elevated the Bcl-2/Bax ratio (P < 0.05 vs.
vehicle), and significantly down-regulated cleaved caspase 3 and caspase 9 expression (P < 0.05 vs.
vehicle) at both 36 mg/kg and 72 mg/kg; more effectively reduced Bax protein levels at 72 mg/kg compared to 36 mg/kg (P < 0.05), with no significant differences between doses for caspase inhibition.

Dosage:8 mg/kg; 16 mg/kg; 32 mg/kg
-
Administration:p.o.; single dose
-
Result:Elevated pain thresholds to 28.0 ± 7.0 s, 32.0 ± 7.3 s, and 35.5 ± 7.3 s at 20, 180, and 240 min post-administration for 32 mg/kg dose (P < 0.05 vs control).
Elevated pain threshold to 28.5 ± 6.9 s at 360 min post-administration for 16 mg/kg dose (P < 0.05 vs control).
Did not produce significant pain threshold elevations at any time point for 8 mg/kg dose.\nReduced the number of abdominal writhing responses to 18.8 ± 4.4 for 32 mg/kg dose (P < 0.05 vs control).
Did not produce significant reductions in writhing responses for 8 mg/kg and 16 mg/kg doses.

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.
