Kahweol
Based on 1 publication(s) in Google Scholar
Kahweol is one of the consituents of the coffee from Coffea Arabica with anti-inflammatory anti-angiogenic, and anti-cancerous activities. Kahweol inhibits adipogenesis and increase glucose uptake by AMP-activated protein kinase (AMPK) activation. Kahweol induces apoptosis.

AMPK; adipogenesis; apoptosis[1]
Kahweol (20-40 μM; 24 hours) decreases TGF-β-induced CTGF protein expression in AML12 and LX2 cells[1]. Kahweol (20-40 μM; 1 hour) decreases TGF-β-induced phospho-Smad2/3 expression in AML12 cells, but does not affect expression in LX2 cells[1]. Kahweol (20-40 μM) significantly decreased TGF-β-stimulated phospho-ERK and JNK expression in primary hepatocytes only[1]. kahweol (0-25 μg/ml; 6-24 hours) increased the phosphorylation of AMPK and its downstream target Acetyl-CoA carboxylase (ACC) in a time-dependent manner in 3T3-L1 cells[2]. kahweol (0-25 μg/ml) significantly affects protein expression of PPARγ, C/EBPα, FABP4, and FASN, that regulate adipocyte differentiation and lipid metabolism[2].

Solvente y solubilidad
DMSO : 100 mg/mL (318.05 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. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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 (7.95 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (7.95 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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
