英文摘要 | Aim: to design and synthesize a series of novel amino acid-binding 1,5-diarylpyrazole derivatives, which are intended to act as prodrugs with better aqueous solubility than celecoxib, and which will exert potent anti-inflammatory activities after being converted to their parent compounds in vivo. methods: to introduce an amino acid, celecoxib analogs containing amino or methylamino group were synthesized first through multi-step chemical reactions. all the synthesized compounds were screened in an intact cell-based assay in vitro and in carrageenan-induced mouse paw edema in vivo. some active compounds were selected for further evaluation in a carrageenan-induced rat paw edema model. the preliminary pharmacokinetics, experiments were conducted using high performance liquid chromatography/mass spectrometry (hplc/ms). results: celecoxib, 6 of the 1,5-diarylpyrazole class of celecoxib analogs, and their amino acid derivatives (hydrochloride salts) were synthesized. in vitro screening, the hydrochloride salts showed decreased inhibitory effects on cyclooxygenase (cox)-1 and cox-2 compared with their parent compounds, but some exhibited potent anti-inflammatory activity in vivo. compound 4a was selected for further evaluation, and its anti-inflammatory effect was equivalent to that of celecoxib after oral administration in the carrageenan-induced rat paw edema model. at three doses (25 mg/kg, 50 mg/kg, and 100 mg/kg) the percentage inhibition on edema was 20.7%, 52.6%, and 62.6% (for compound 4a) and 27.8%, 38.4%, and 40.1% (for celecoxib), respectively. preliminary pharmacokinetic evaluations support the hypothesis that compound 4a was actually converted to its parent compound, compound 4. conclusion: the compound bound with amino acid acts like prodrug, which can exert anti-inflammatory effect similar to celecoxib after being converted to its parent compound. this finding will be of great benefit in carrying out structural modifications of prodrug-like selective cox-2 inhibitors. |
