COX-2/5-LOX-IN-8
COX-2/5-LOX-IN-8 is an orally active dual COX-2/5-LOX inhibitor, with an IC50 of 6.30 μM against sheep-derived COX-2 and an IC50 of 8.09 μM against 5-LOX. COX-2/5-LOX-IN-8 acts as a membrane stabilizer that stabilizes erythrocyte membranes against hypotonicity-induced hemolysis. COX-2/5-LOX-IN-8 functions as a protein stabilizer that inhibits heat-induced denaturation of bovine serum albumin. COX-2/5-LOX-IN-8 reduces paw swelling, improves hind limb weight-bearing function, decreases serum levels of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, CRP), and lowers serum levels of cartilage degradation biomarkers (COMP, MMP-3, CTX-II). COX-2/5-LOX-IN-8 can be used in the research of osteoarthritis.

COX-2/5-LOX-IN-8 (Compound 9) potently stabilizes rat erythrocyte membranes and resists hypotonicity-induced hemolysis, with an IC50 of 51.60 μM[1].
COX-2/5-LOX-IN-8 (31.25-500 μg/mL; 20 min (37 °C); 3 min (60 °C)) effectively inhibits heat-induced bovine serum albumin (BSA) denaturation[1].
COX-2/5-LOX-IN-8 (0.5-1000 μg/mL; 10 min) potently and selectively inhibits ovine COX-2, with an IC50 of 6.30 μM[1].
COX-2/5-LOX-IN-8 (0.5-1000 μg/mL; 10-15 min) potently inhibits 5-LOX with an IC50 value of 8.09 μM[1].

Animal Model:Wistar (male; osteoarthritis induced by intra-articular injection of 50 μL of 80 mg/mL mono-iodoacetate into the right ankle joint)[1]
-
Dosage:150 mg/kg
-
Administration:p.o.; daily; 7 consecutive days
-
Result:Reduced paw edema volume to 0.08 cm3, corresponding to 98% inhibition relative to the MIA-induced control group.
Restored hind-limb weight-bearing ratio to 1.00, matching the normal control group.
Caused 80-85% reductions in serum levels of pro-inflammatory markers TNF-α, IL-1β, and CRP, bringing levels comparable to the normal control group.
Caused 70-85% reductions in cartilage degradation markers COMP, MMP-3, and CTX-II.
