  Discovery of imidazo[1,2-b]pyridazines as IKKβ inhibitors. Part 3: Exploration of effective compounds in arthritis models

  摘要：

  We have discovered imidazo[1,2-b]pyridazine derivatives that show suppressive activity of inflammation in arthritis models. We optimized the substructures of imidazo[1,2-b] pyridazine derivatives to combine potent IKK beta inhibitory activity, TNF alpha inhibitory activity in vivo and excellent pharmacokinetics. The compound we have acquired, which had both potent activities and good pharmacokinetic profiles based on improved physicochemical properties, demonstrated efficacy on collagen-induced arthritis models in mice and rats.
