Aloe-emodin-8-O-β-D-glucopyranoside targets protein tyrosine phosphatase 1B (PTP1B) (IC₅₀ = 38.5 μM) [1]
|
|---|---|
| ln Vitro |
- Aloe-emodin-8-O-β-D-glucopyranoside exhibited dose-dependent inhibitory activity against recombinant human PTP1B enzyme, with an IC₅₀ value of 38.5 μM [1]
- The compound showed no significant inhibitory effect on other phosphatases (e.g., TCPTP) at concentrations up to 100 μM, indicating moderate selectivity for PTP1B [1] |
| Enzyme Assay |
- Recombinant human PTP1B enzyme was used for the inhibition assay, with p-nitrophenyl phosphate (pNPP) as the synthetic substrate [1]
- The reaction was conducted in a buffer system at 37°C, with serial dilutions of Aloe-emodin-8-O-β-D-glucopyranoside (0.1-100 μM) added to the mixture of enzyme and substrate [1] - After incubation for a specific period, the reaction was terminated by adding a stop solution, and the absorbance of the product (p-nitrophenol) was measured spectrophotometrically at 405 nm [1] - The inhibitory rate of PTP1B activity was calculated by comparing the absorbance of the treatment group with the blank control group, and the IC₅₀ value was determined via nonlinear regression analysis of the dose-response curve [1] |

| Additional Infomation |
It has been reported that rhubarb (Rheum palmatum), senna leaf (Senna alexandrina) and medicinal rhubarb (Rheum officinale) all contain aloe-emodin-8-O-β-D-glucopyranoside, and there is relevant data.
- Aloe-emodin-8-O-β-D-glucopyranoside is a natural compound isolated from the plant Saussrurea lappa (commonly known as Aucklandia lappa or Saussurea costus root)[1] - As a PTP1B inhibitor, this compound has potential application value in the treatment of metabolic diseases (such as type 2 diabetes) and cancer, because PTP1B is involved in regulating insulin signaling pathways and oncogenic pathways[1] - This compound is a glycosylated derivative of aloe-emodin, and the glucopyranoside moiety may affect its solubility and bioactivity compared to the aglycone form[1] |

| Solubility (In Vitro) |
DMSO : ~50 mg/mL (~115.64 mM)
|
|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (5.78 mM) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.3128 mL | 11.5639 mL | 23.1278 mL | |
| 5 mM | 0.4626 mL | 2.3128 mL | 4.6256 mL | |
| 10 mM | 0.2313 mL | 1.1564 mL | 2.3128 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
