Provided is a compound which is useful as an active ingredient for a pharmaceutical having a PKCθ inhibition activity, particularly a pharmaceutical composition for inhibiting acute rejection occurring in transplantation. The present inventors have conducted extensive studies on a compound having a PKCθ inhibition activity, and as a result, they have found that a compound having a structure such as aralkyl and the like on an amino group at the 2-position and also having a structure such as an adamantylalkyl group and the like on an amino group at the 4-position of 2,4-diaminopyrimidine, or a salt thereof has an excellent PKCθ inhibition activity, thereby completing the present invention. The 2,4-diaminopyrimidine compound of the present invention can be used as a PKCθ inhibitor or an inhibitor of acute rejection occurring in transplantation.
提供了一种化合物,可用作具有PKCθ抑制活性的药物的活性成分,尤其是用于抑制移植中发生的急性排斥的药物组合物。本发明者对具有PKCθ抑制活性的化合物进行了广泛的研究,结果发现,在2-位氨基上具有类似芳基烷基等结构,在4-位氨基上具有类似于金刚烷基烷基等结构的2,4-二氨基嘧啶化合物,或其盐具有出色的PKCθ抑制活性,从而完成了本发明。本发明的2,4-二氨基嘧啶化合物可用作PKCθ抑制剂或用于抑制移植中发生的急性排斥的抑制剂。
