    Pancreatic acini exposed for 1 h to 300 μM of oleic acid (OA) or linoleic acid (LA) were pre-treated for 45 min with the vehicle (DMSO), JSH-23 (30 μM) or SH-4-54 (10 μM). CCL2 mRNA expression was analyzed by qRT-PCR with 18S as internal standard. *p<0.05, **p<0.01 as compared with untreated acini, ♦♦p<0.01 as compared with OA- or LA-treated acini.

Biological Activity

Description JSH-23 is an inhibitor of NF-κB transcriptional activity with IC50 of 7.1 μM in RAW 264.7 cell line.
Targets
NF-κB [1]
(RAW 264.7 cells)
7.1 μM
In vitro

JSH-23 inhibits LPS-induced nuclear translocation of NF-κB p65 without affecting IκBα degradation. JSH-23 inhibits LPS-induced apoptotic chromatin condensation, while does not show significant cytotoxic effects on the RAW 264.7 cells at <100 μM. [1] JSH-23 also decreases NO production and neuronal migration in LPS activated cultures primary cultures from developing mouse cerebellum. [2] Moreover, JSH-23 augments cisplatin cytotoxicity in ovarian cancer cells with CI values ranging from 0.35 to 0.85. [3]

In vivo JSH-23 (3 mg/kg) significantly reverses the nerve conduction and nerve blood flow deficits by decreasing neuroinflammation and improving antioxidant defence in diabetic rats. [4]

Protocol

Kinase Assay:[1]
+ Expand

Measurement of NF-κB transcriptional activity:

Macrophages RAW 264.7 transfected stably with reporter plasmid of pNF-κB-SEAP-NPT are treated with 1 μg/ml LPS and/or sample for 16 hours. As the reporter, SEAP activity in the cell-free culture media is measured as followed. Single cell-derived stable transfectants are plated in 5 ml of T-25 flask, and the media is decanted 24 h later. At this time, cells are washed twice with phosphate-buffered saline, and incubations are initiated by addition of new media. Chemicals are added to the culture medium after 24 h of incubations. Aliquots (25 ml) of medium from a control or chemical-treated cultures are taken at 0, 3, 20, 24, 48, and 72 h, heated at 65°C for 5 min to eliminate the alkaline phosphatase activity, and used immediately or stored at -20°C. Mixtures consisting of dilution buffer (25 ml), assay buffer (97 ml), culture media (25 ml), and 4-methylumbelliferyl phosphate (MUP, 1 mM, 3 ml) in each well of the 96-well plates are incubated for 60 min in the dark at room temperature. Fluorescence emits the product of the SEAP/MUP is measured at 449 nm using a 96-well plate fluorometer after excitation at 360 nm.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
