(別名: Pterosin B)

カスタマーレビュー

Based on 1 Customer Validation

Pterosin B is an orally active indanone. Pterosin B can be obtained from Pteridium aquilinum. Pterosin B is a Sik3 signaling inhibitor. Pterosin B inhibits Klf5 expression and reduces β-amyloid deposition. Pterosin B prevents chondrocyte hypertrophy and osteoarthritis in mice. Pterosin B inhibits cardiomyocyte hypertrophy, improves cognitive impairment, and lowers blood glucose. Pterosin B can be used in research on arthritis, Alzheimer's disease, pathological cardiac hypertrophy and diabetes.

Pterosin B (300 μM; 5 days) reduces the amounts of Sik3, phosphorylated Hdac4, and phosphorylated Crtc1 in primary chondrocytes, similar to the effect of 4-OH tamoxifen^[2].
Pterosin B (10-50 μM; 48 h) inhibits Angiotensin II-induced cardiomyocyte hypertrophy in H9c2 cells, reducing hypertrophy-related gene expression, cell size, and protein synthesis^[3].
Pterosin B (1, 5 μM) promotes the phenotypic shift of lipopolysaccharide-induced BV-2 cells from M1 to M2, inhibits Klf5 expression, and attenuates Lipopolysaccharide-induced microglial glycolysis^[4].
Pterosin B (300 μM; 36 h) inhibits the SIK3 signaling pathway, suppressing the cytoplasmic localization of HDAC5 and CRTC2 in HEK293 cells^[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

体内実験

Pterosin B (900 μM; intra-articular injection; 3 times a week; 8-12 weeks) protects mice from the development of osteoarthritis and reduces the expression of Col10 in the non-calcified zone of articular cartilage in wild-type mouse knee osteoarthritis models^[2].
Pterosin B (5-20 mg/kg; p.o.; 8 weeks) ameliorates cognitive deficits, reduces β-amyloid deposition, and inhibits excessive microglia activation in APP/PS1 mice^[4].
Pterosin B (0.1% in diet; p.o.; 1 month) lowers blood glucose levels and enhances insulin responses in db/db mice^[5].

Dosage:

5 mg/kg/day and 20 mg/kg/day (dissolved in 0.5% sodium carboxymethyl)
Administration:

Oral administration, for 8 weeks
Result:

Reduced escape latency and increased the number of platform crossings and target-zone duration.
Improved learning and memory.
Rescued the decline in spontaneous alternation rate.
Revealed a significant decrease in the Aβ_1-42-positive area.
Improved the number and arrangement of Nissl bodies in the hippocampal DG region.
Decreased the number of microglia in the cortex and CA1 region and inhibited the elevation of mRNA levels of inflammatory factors such as Tnfa, Il6, and Il1b in the hippocampus and serum.

Stock Solution Working Solution

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.75 mg/mL (12.60 mM); Clear solution

This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.75 mg/mL (12.60 mM); Clear solution

This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.75 mg/mL (12.60 mM); Clear solution

This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
