Discovery of imidazo[1,2-b]pyridazines as IKKβ inhibitors. Part 2: Improvement of potency in vitro and in vivo
摘要:
We have increased the potency of imidazo[1,2-b]pyridazine derivatives as IKK beta inhibitors with two strategies. One is to enhance the activity in cell-based assay by adjusting the polarity of molecules to improve permeability. Another is to increase the affinity for IKK beta by the introduction of additional substituents based on the hypothesis derived from an interaction model study. These improved compounds showed inhibitory activity of TNF alpha production in mice. (C) 2010 Elsevier Ltd. All rights reserved.
