Application

NS-398 has been used as a cyclooxygenase-2 (COX2) inhibitor to study its effects on:
  • the cardiac rate in zebrafish embryos
  • apoptosis and hypoxia/reoxygenation in rat cardiomyocytes
  • the lipopolysaccharide (LPS) induced anorexia in rats

Biochem/physiol Actions

NS-398 belongs to the non-steroidal anti-inflammatory drug (NSAID) family. It exhibits anti-inflammatory, analgesic, and anti-pyretic properties.
Selective cyclooxygenase-2 (COX-2) inhibitor.

The epithelial-mesenchymal transition (EMT) is important in organ fibrosis. We hypothesized that growth arrest-specific protein 6 (Gas6) and its underlying mechanisms play roles in the prevention of EMT in alveolar epithelial cells (ECs). In this study, to determine whether Gas6

Neuronal ubiquitin C-terminal hydrolase L1 (UCHL1) is a deubiquitinating enzyme that maintains intracellular ubiquitin pools and promotes axonal transport. Uchl1 deletion in mice leads to progressive axonal degeneration, affecting the dorsal root ganglion that harbors axons emanating to the kidney.

1. NS-398 (N-[2-cyclohexyloxy-4-nitrophenyl] methanesulfonamide) is a new non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic effects. 2. The anti-inflammatory potency of NS-398 in rat carrageenin-induced edema was as potent as that of indomethacin and 8 times more potent than diclofenac.
