    In an attempt to prepare a new water-soluble, parenteral COX-2 inhibitor, rofecoxib (9) and celecoxib (13) analogues were designed and synthesized for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors with in vivo anti-inflammatory activity. In this experiment, respective SO(2)Me and SO(2)NH(2) hydrogen-bonding pharmacophores were replaced by a tetrazole ring. Molecular modeling (docking) studies showed that the tetrazole ring of these two analogues (9 and 13) was inserted deep into the secondary pocket of the human COX-2 binding site where it undergoes electrostatic interaction with Arg(513). The rofecoxib (9) and celecoxib (13) analogues exhibited a high in vitro selectivity (9, COX-1 IC(50) = 3.8 nM; COX-2 IC(50) = 1.8 nM; SI = 2.11; 13, COX-1 IC(50) = 4.1 nM; COX-2 IC(50) = 1.9 nM; SI = 2.16) relative to the reference drug celecoxib (COX-1 IC(50) = 3.7 nM; COX-2 IC(50) = .2 nM; SI=1.68) and also showed high aqueous solubility at pH higher than 7 and good anti-inflammatory activity in a carrageenan-induced rat paw edema assay. However, 9 and 13 had no significant damage on gastric mucosa.
