Outline of Final Research Achievements |
The aim of this study is to find suitable radioligands for PET studies which are targeted COX-2 in brain. Nimesulide derivatives are selected as a ligand expecting brain uptake. We synthesized six isomeric methoxy-/iodo- analogs of nimesulide, and evaluated for potential as radioligands for brain COX-2 imaging. All synthesized compounds were shown suitable parameters for favorable brain penetration, and three compounds were found as potent and selective COX-2 inhibitors. Furthermore, three isomeric methoxy analogs of nimesulide have been 14C-radiolabeled. Future studies will aim to develop radiolabeled forms of this nimesulide analog for further in vivo evaluation.
