 3.100mg/ml (9.86mM) Taking the 1 mL working solution as an example, add 50 μL of 62 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 NS-398 (N-(2-cyclohexyloxy-4-nitrophenyl)methane sulfonamide) is a selective inhibitor of cyclooxygenase-2 (COX-2). The IC50 values for human recombinant COX-1 and -2 are 75 and 1.77 μM, respectively.
in vitro

NS-398 (NS398) inhibits COX-2 enzyme activity in a concentration dependent manner, the IC50 being 3.8 μM, whereas this compound at 100μM has no effect on COX-1 activity[1]. At 10 μM, it treatment results in increased production of COX-2 and the pro-inflammatory cytokine. This compound (10 μM) induces apoptosis in LNCaP cells, but not in the more aggressive, androgen-unresponsive C4-2b cells. The C4-2b cells are observed to continue to proliferate when treated with NS-398 and continues to retain malignant phenotype characteristics. Its treatment results in C4-2b cell differentiation into an unusual neuroendocrinelike cell. These neuroendocrine-like cells produces both epithelial (cytokeratin 18 and prostate specific antigen) and neuronal (neuron-specific enolase and chromogranin A) proteins. Furthermore, this C4-2b cellular response to it is mediated by NF-kB transcription factor activation. It induces NF-kB and down-regulates Ikβ-α protein expression in LNCaP C4-2b cells[2].
in vivo

NS398 (NS-398) could inhibit Cox-2 expression induced by acoustic injury and attenuate noise-induced hearing threshold shifts and cochlear hair cell loss. The inhibition of Cox-2 by this compound could attenuate Noise-induced hearing loss（NIHL）and related hair cell damage.[3].

反応時間 24, 48, 72 h
実験の流れ

1×106 cells are plated in six well cluster plates with 2 ml of medium for 24 h. At time point 0, medium was removed, cells were carefully washed with phosphate buffered saline (PBS) and serum free(SF), phenol-red free medium containing 0.5 μg/ml BSA was added. Incubations are continued for an additional 72 h with or without increasing concentrations of NS-398 (NS398). Cells and culture medium are harvested at 24 h time intervals. Dead cells are removed by gentle washing with PBS and cell number determined by direct counting using trypan blue dye exclusion to identify viable cells. DMSO (0.1%) is added to control cultures.
