COX-2/CA II-2
COX-2/CA II-2 is an orally active dual selective inhibitor targeting COX-2 and hCA II. COX-2/CA II-2 inhibits COX-2 with an IC50 value of 0.05 μM (SI = 12.02 vs COX-1) and hCA II with a Ki value of 62.6 nM (SI = 704.2 vs hCA I). COX-2/CA II-2 demonstrates significant analgesic and anti-inflammatory effects with rapid onset and sustained duration in animal models, shows improved gastric safety with reduced ulcerogenic liability, and exhibits a gradual intraocular pressure (IOP)-lowering effect without statistical significance relative to the sham-treated eye in rabbit glaucoma models. COX-2/CA II-2 can be used for anti-inflammatory, analgesic and antiglaucoma research.

COX-2 0.05 μM (IC50) |
COX-1 0.64 μM (IC50) |
hCA II 62.6 nM (Ki) |
hCA XII 69.7 nM (Ki) |
hCA I 44,080 nM (Ki) |
COX-2/CA II-2 (compound 5d) inhibits COX-1 with an IC50 of 0.64 μM and COX-2 with an IC50 of 0.05 μM, corresponding to a selectivity index (SI) of 12.02[1].
COX-2/CA II-2 inhibits hCA II with a Ki of 62.6 nM, hCA XII with a Ki of 69.7 nM, and hCA I with a Ki of 44,080 nM, with selectivity indices SI I/II = 704.2 and SI XII/II = 1.11[1].
COX-2/CA II-2 binds to the hCA II active site (PDB: 1Z9Y), forming Zn coordination, hydrogen bonds with Thr199/Thr200 and Gln92, and π-π stacking with Phe131[1].
COX-2/CA II-2 binds to the COX-2 active site (PDB: 5KIR), forming hydrogen bonds with Arg513, Phe518, Gln192 and Leu352, and π-π stacking with Tyr355[1].

COX-2/CA II-2 (50 mg/kg; p.o.; single dose for 6 h) exhibits anti-inflammatory activity with an apparent early onset of action, reduces carrageenan-induced paw edema with inhibition rates of 23.6% (1 h), 9.8% (2 h), 49.2% (3 h), 49.2% (4 h), 67.9% (5 h) and 72.3% (6 h) in the carrageenan-induced paw edema model using adult male albino rats[1].
COX-2/CA II-2 (50 mg/kg; p.o.; single dose for 24 h) attenuates gastric irritation, affording 100% protection at 1 h and 49.8% protection (vs Ibuprofen) at the 24 h time point in acute Gastric Ulcer Model using adult male albino rats[1].
COX-2/CA II-2 (0.05% solution, 0.1 mL; topical administration) shows a gradual intraocular pressure (IOP)-lowering effect without statistical significance relative to the sham-treated eye in the hypertonic saline-induced glaucoma model using adult male New Zealand albino rabbits[1].
