| Hazard Information | Back Directory | [Uses]
Selective COX-1 inhibitor (IC50=9nM). Shows 700-fold more selectivity over COX-2 (IC50=6.3μM). Inhibits COX-1-derived platelet thromboxane B2, gastric PGE2, and dermal PGE2 production. Orally active in rat. | [Definition]
ChEBI: A member of the class of pyrazoles that is 1H-pyrazole which is substituted at positions 1, 3 and 5 by 4-methoxyphenyl, trifluoromethyl and 4-chlorophenyl groups, respectively. Unlike many members of the diaryl heterocycle class of cyclo
xygenase (COX) inhibitors, SC-560 is selective for COX-1. | [Biological Activity]
Highly selective cyclooxygenase-1 (COX-1) inhibitor (IC 50 values are 0.009 and 6.3 μ M for COX-1 and COX-2 respectively). Inhibits COX-1-derived platelet thromboxane B 2 , gastric PGE 2 and dermal PDE 2 production. Significantly reduces ovarian surface epithelial tumor growth in vivo . Orally active. | [Biochem/physiol Actions]
SC-560 (5-(4-chlorophenyl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole) is a non-steroidal anti-inflammatory drug (NSAID). It is a lipophilic, diaryl heterocyclic compound. SC-560 acts as an effective antiviral agent against hepatitis C virus (HCV). It also has a potential to hinder prostaglandin E2 synthesis in neurons at nanomolar concentrations. | [in vitro]
preincubation of cox-1 with sc-560 inhibited the conversion of arachidonic acid to pge2 in a concentration-dependent manner [1]. sc-560 was necessary to sustain a reduced basal level of pgi2 for an extended period. sc-560 inhibits cell proliferation and accelerates apoptosis which results in attenuated tumor growth [2]. | [in vivo]
oral dosing with either 10 or 30 mg/kg sc-560 1 hr before assay completely inhibited cox-1-derived platelet thromboxane b2, gastric pge2, and dermal pge2 production [1]. sc-560 can suppress ovarian surface epithelial tumor growth. tumor growth was suppressed in allografted mice treated with sc-560 for a longer period, but the reduction in tumor growth was less dramatic than the short-term treated [2]. | [IC 50]
