この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。

 4.000mg/ml (24.36mM) Taking the 1 mL working solution as an example, add 50 μL of 80 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 4-PBA (4-Phenylbutyric acid) is a histone deacetylase (HDAC) inhibitor and a key epigenetic inducer of anti-HCV hepatic hepcidin. 4-Phenylbutyric acid inhibits LPS-induced inflammation through regulating endoplasmic-reticulum (ER) stress and autophagy in acute lung injury models.
in vitro

4-Phenylbutyric acid (4-PBA) inhibits the ER stress induced by SiNPs in RAW264.7 cells, as evidenced by the expansion and degranulation of ER, as well as greatly up-regulated Bip and CHOP expressions.[3]
in vivo

4-Phenylbutyric acid (4-PBA) attenuates LPS-induced bone loss in lipopolysaccharide (LPS)-treated mice, by increasing area of TRAP-positive osteoclasts (OCs) and serum level of collagen type I fragments.[4]

細胞アッセイ 細胞株 Mouse macrophage cell line, RAW264.7 cells
濃度 3 mM
反応時間 6 h
実験の流れ

Mouse macrophage cell line, RAW264.7 cells are cultured in DMEM with 10% fetal bovine serum at 37 ℃ in a 5% CO2 incubator. SiNPs are diluted by DMEM to appropriate concentrations, and an ER stress inhibitor, 4-phenylbutyric acid (4-PBA), is applied (3 mM, 6 h). The SiNPs-treated group is at a concentration of 50 μg/ml in vitro experiments. Similarly, the application of this compound is set up through MTT assay, after SiNPs with or without 4-PBA treatment, cells are harvested for the following measurement. The levels of Bip and CHOP induced by SiNPs are measured.
動物実験 動物モデル mice are injected daily intraperitoneally in 200 μl PBS (or with PBS as a vehicle) at a dose of 240 mg/kg for 3 weeks.
