| | Imrecoxib Usage And Synthesis |
| Uses | Imrecoxib (BAP-909) is a novel and selective cyclooxygenase 2 (COX-2) inhibitor with an IC50 value of 18 nM, it also inhibits COX1- activity with an IC50 value of 115 nM. Imrecoxib (BAP-909) has anti-inflammatory effect[1]. | | Clinical Use | Imrecoxib, a new non-steroid anti-inflammtory drug (NSAID), was launched in China with the trade
name of Hengyang® for the treatment of osteoarthritis in 2012. It was originally designed and
synthesized by Guo and co-workers at the Institute of Materia Medica (IMM) of the Chinese Academy
of Medical Sciences in collaboration with Hengrui Pharmaceuticals. Imrecoxib, which is a moderately
selective COX-2 inhibitor (with IC50 values against COX-1 and COX-2 being 115 ± 28 nM and 18 4
nM, respectively). | | Synthesis | Imrecoxib has had two synthetic routes reported across several publications. The most likely process-scale route to this drug is described in the scheme, which began with 2-bromo-4'-(methylsulfonyl)-acetophenone (84) and p-tolylacetic acid (85) as starting materials. In the
presence of base, |á-bromoketone 84 was treated with acid 85 which resulted in lactone 86 in 72% yield
across the two-step sequence. Exposure of lactone 86 with propylamine triggered a ring-opening-ring
closing reaction, which resulted in imrecoxib (XIII) directly in 85% yield. 
| | in vivo | Imrecoxib (BAP-909) (gastrointestinal administration; 5-20 mg/kg; 1 hour before carrageenan injection) inhibits carrageenan-induced acute inflammation, and the inhibitory effect is maximal at 4 hours[1].
Imrecoxib (BAP-909) (gastrointestinal administration; 5-20 mg/kg; started on day 7; 26 days) diminishes the secondary paw swelling and inhibits heat-inactivated BCG induced-inflammtory polyarthritis[1]. | Animal Model: | Rat carrageenan-induced edema model[1] | | Dosage: | 5 mg/kg, 10 mg/kg, 20 mg/kg | | Administration: | Gastrointestinal administration; 5-20 mg/kg; 1 hour before carrageenan injection | | Result: | Inhibited the edema response with different doses. |
| Animal Model: | Rat adjuvant-induced arthritis (AIA) model[1] | | Dosage: | 5 mg/kg, 10 mg/kg, 20 mg/kg | | Administration: | Gastrointestinal administration; 5-20 mg/kg; started on day 7; 26 days | | Result: | Inhibited adjuvant-induced chronic inflammation at the doses of 10 and 20 mg/kg. |
