| Hazard Information | Back Directory | [Description]
NS-398 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. The IC50 values for ovine COX-1 and -2 are 220 and 0.15 μM, respectively. | [Uses]
Cyclooxygenase inhibitor. Selectively inhibits PGH synthase-2 (IC50=1 μM) with no inhibition of PGH synthase-1 at concentrations up to 100 μM. Protects neuronal cultures from LPS-induced neurotoxicity. | [Definition]
ChEBI: A C-nitro compound that is N-methylsulfonyl-4-nitroaniline bearing an additional cyclohexyloxy substituent at position 2. | [Biological Activity]
Selective cyclooxygenase-2 inhibitor (IC 50 values are 3.8 and > 100 μ M for COX-2 and COX-1 respectively). Induces apoptosis in colorectal tumor cells and elevates COX-2 protein expression in vitro . Orally active and non-ulcerogenic analgesic and anti-inflammatory in vivo . | [storage]
Store at -20℃ | [References]
