The present invention provides 2,4-pyrimidinediamine compounds that inhibit the IgE and/or IgG receptor signalling cascades that lead to the release of chemical mediators, intermediates and methods of synthesizing the compounds and methods of using the compounds in a variety of contexts, including in the treatment and prevention of diseases characterized by, caused by or associated with the release of chemical mediators via degranulation and other processes effected by activation of the IgE and/or IgG receptor signalling cascades.
本发明提供了可抑制导致化学介质释放的 IgE 和/或 IgG 受体信号级联的 2,4-嘧啶二胺化合物、合成这些化合物的中间体和方法,以及在各种情况下使用这些化合物的方法,包括治疗和预防以通过脱颗粒释放化学介质为特征、由脱颗粒释放化学介质引起或与脱颗粒释放化学介质相关的疾病,以及由 IgE 和/或 IgG 受体信号级联激活所影响的其他过程。
