COX-2 Inhibitors - Still the best answer for inflammatory pain?

There is renewed interest in COX inhibitors not only for inflammation, but also for other indications such as cancer chemoprevention and antithrombosis. Cayman has COX inhibitors that span the selectivity spectrum, from highly COX-1 selective to many thousand-fold COX-2 selective (see CAY10404). We can work together with you to customize a COX inhibitor with the best activity/selectivity profile to suit your needs.
