, and Q, shown in Formula I are defined herein. Pharmaceutical compositions containing one or more compounds of Formula I, or a pharmaceutically acceptable form of such compounds, and one or more pharmaceutically acceptable carriers, excipients, or diluents are provided herein. Methods of treating patients suffering from certain diseases responsive to inhibition of tyrosine kinase activity are also given. In certain embodiments the diseases are responsive to inhibition of Btk activity and/or B-cell proliferation. Such methods comprise administering to such patients an amount of a compound of Formula I effective to reduce signs or symptoms of the disease. These diseases include cancer, an autoimmune and/or inflammatory disease, or an acute inflammatory reaction. Thus methods of treatment include administering a sufficient amount of a compound or salt as provided herein to decrease the symptoms or slow the progression of these diseases. Other embodiments include methods of treating other animals, including livestock and domesticated companion animals, suffering from a disease responsive to inhibition of kinase activity. Methods of treatment include administering a compound of Formula I as a single active agent or administering a compound of Formula I in combination with one or more other therapeutic agent. A method for determining the presence of Btk in a sample, comprising contacting the sample with a compound or form thereof of Formula I under conditions that permit detection of Btk activity, detecting a level of Btk activity in the sample, and therefrom determining the presence or absence of Btk in the sample.
本文描述了公式I的化合物及其所有药学上可接受的形式。公式I中所示的变量R1、R2、R3、Z2和Q在此定义。本文提供了含有一个或多个公式I化合物或其药学上可接受的形式以及一个或多个药学上可接受的载体、辅料或稀释剂的制药组合物。本文还提供了治疗对酪氨酸激酶活性抑制具有响应的某些疾病的方法。在某些实施例中,这些疾病对Btk活性和/或B细胞增殖的抑制具有响应。这些方法包括向这些患者施用足够量的公式I化合物,以减少疾病的体征或症状。这些疾病包括癌症、自身免疫和/或炎症性疾病或急性炎症反应。因此,治疗方法包括向患者施用足够量的公式或盐,以减轻这些疾病的症状或减缓其进展。其他实施例包括治疗其他动物,包括家畜和驯养的伴侣动物,患有对激酶活性抑制具有响应的疾病。治疗方法包括将公式I化合物作为单一活性剂或与一个或多个其他治疗剂联合使用。一种用于确定样品中Btk存在的方法,包括在允许检测Btk活性的条件下,将样品与公式I化合物或其形式接触,检测样品中Btk活性的水平,并据此确定样品中Btk的存在或不存在。
