Biological Activity

[Description]:

Mofezolac, a non-steroidal anti-inflammatory drug (NSAID), is a selective, reversible and orally active COX-1 inhibitor with an IC50 of 1.44 nM. Mofezolac shows weak inhibitory activity on COX-2 (IC50 of 447 nM). Mofezolac can relieve pain and has anti-inflammatory activities[1].

[Target]

COX-1:1.44 nM (IC50)

COX-2:447 nM (IC50)

[In Vitro]

Mofezolac inhibits platelet aggregation with an IC50 of 0.45 μM in human platelet rich plasma (hPRP) assay[2]. Mofezolac slightly increase Bortezomib cytotoxic effect on multiple myeloma (MM) cell lines (NCI-H929 and RPMI-8226) and affects MM cell cycle and apoptosis when co-administered with the proteasome inhibitor Bortezomib[2].

[In Vivo]

Mofezolac (1-30 mg/kg; oral administration; once) treatment results in the suppression of writhing induced by the intraperitoneal injection of phenyl-p-benzoquinone in mice[1]. Animal Model: Female ddY mice (4 week old, 18-27 g) injected with phenyl-p-benzoquinone (PQ)[1] Dosage: 1 mg/kg, 3 mg/kg, 10 mg/kg, 30 mg/kg Administration: Oral administration; once Result: Dose-dependently suppressed the writhing induced by PQinjection in mice.
