| | NS-398 Usage And Synthesis |
| 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 | NS-398 is a selective Cox-2 inhibitor neuroprotective agent. | | 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 RT | | references | [1]. futaki n, takahashi s, yokoyama m, et al. ns-398, a new anti-inflammatory agent, selectively inhibits prostaglandin g/h synthase/cyclooxygenase (cox-2) activity in vitro. prostaglandins, 1994, 47(1): 55-59.
