Skimmin
Based on 1 publication(s) in Google Scholar
Skimmin (Umbelliferone glucoside) is a major pharmacologically active and orally active molecule present in Hydrangea paniculata, a medical herb used in traditional Chinese medicine as an anti-inflammatory agent. Skimmin has renal protective activity. Skimmin can improve creatinine clearance, and reduce plasma creatinine, and kidney injuries. Skimmin has good anti-amoebic activity against the HM1:IMMS strain of Entamoeba histolytica. Skimmin has anti-cancer and neuroprotective activities. Skimmin reduces cardiac fibrosis as well as decreasing TNF-α, IL-6, IL1β, and TGFβ1 in cardiac tissues. Skimmin can be studied in research for diabetes and diabetes-related diseases.

Skimmin (15-30 mg/kg, i.g., 16 w) showed a certain effect on decreasing blood glucose in male SD rats[3].
Skimmin (7.5-30 mg/kg, p.o., 17 w) results in significantly less severe sclerosis in glomerulus segments especially at 15 mg/kg and 30 mg/kg dose in Wistar rats[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Administration:Intragastric injection (i.g.) daily from days 37 to 66
-
Result:Reduced BUN whilst increased Ucr and urinary creatinine (Ccr) with 30 mg/kg dose.
Significantly reduced C-BSA-induced morphological changes including incidences of glomerular hypercellarity, glomerular basement membrane thickening or mesangial proliferation, and tubulointerstitial injuries.
Led to significantly less deposits of immune complexes in the mesangial areas and along the capillary walls.
Reduced the IgG positive staining area by 41% compared to model group.
Decreased the expression of IL-1β and IL-6 in glomeruli dose-dependently.
Reduced the CD20 mature B cell infiltration significantly.

Dosage:15 or 30 mg/kg
-
Administration:Intragastric injection (i.g.) daily for 16 w
-
Result:Lightly reduced the HR, SBP, DBP, and MAP.
Significantly improved cardiac function in diabetic rats dose dependently.
Significantly reduced the heart NO and malondialdehyde (MDA) concentration and increased GSH concentration in the heart.
Increased the enzyme activity of SOD and CAT in the heart tissues.
Showed anti-inflammatory activity by decreasing TNF-α, IL-6, IL1β, and TGFβ1 in the heart tissues from DCM rats.
Exerted a cardiac protective effect and inhibited the NLRP3 pathway in diabetic hearts by decreasing NLRP3, caspase-1, and IL-1β.
Reduced the P62 protein level in the heart tissues.
-
Animal Model:Adult male Wistar rats (180-200 g) with Streptozotocin (60 mg/kg)-induced diabetic nephropathy[4]
-
Dosage:7.5, 10, 30 mg/kg
-
Administration:Oral gavage (p.o.) for 17 weeks
-
Result:Reduced the incidence of tubule vacuolar degeneration and severity level.
Decreased TGF-β1 expression on mRNA level in the renal tissues dose dependently.

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
