Application

SC-560 has been used as a cyclooxygenase-1 (COX-1) inhibitor to study its effects on prostaglandin E-2 (PGE2) signaling in ciliogenesis in zebrafish embryos. It has also been used as a selective inhibitor of COX-1 to study its role in PM10-induced endothelial dysfunction.

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.
SC-560 belongs to the diaryl heterocycle class of cyclooxygenase (COX) inhibitors. It exhibits anti-tumor and anti-proliferative activities.
Selective cyclooxygenase-1 (COX-1) inhibitor, exhibiting 700-fold selectivity for COX-1 over COX-2.

Prostaglandins and thromboxane are lipid signaling molecules deriving from arachidonic acid by the action of the cyclooxygenase isoenzymes COX-1 and COX-2. The role of cyclooxygenases (particularly COX-2) and prostaglandins (particularly PGE₂) in cancer-related inflammation has been extensively investigated. In contrast
Inhibition of prostaglandin E2 synthesis by SC-560 is independent of cyclooxygenase 1 inhibition
