Compounds of Formula (I-a) and all pharmaceutically-acceptable forms thereof, are described herein. The variables R1, R2, R3, Z1, Q, and A shown in Formula I-a are defined herein. Pharmaceutical compositions containing one or more compounds of Formula (I-a), 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-a) 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-a) as a single active agent or administering a compound of Formula (I-a) 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-a) 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.
本文描述了化合物的化学式(I-a)及其所有药用可接受形式。在化学式I-a中显示的变量R1、R2、R3、Z1、Q和A在此处被定义。本文提供了含有一个或多个化学式(I-a)化合物或该化合物的药用可接受形式以及一个或多个药用可接受载体、辅料或稀释剂的药物组合物。还提供了治疗对酪氨酸激酶活性抑制敏感的患者的方法。在某些实施例中,这些疾病对Btk活性和/或B细胞增殖的抑制敏感。这些方法包括向这些患者投予有效减轻疾病症状的化学式(I-a)化合物的量。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投予足够量的本文所述的化合物或盐,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,包括牲畜和驯养的伴侣动物,患有对激酶活性抑制敏感的疾病的方法。治疗方法包括将化学式(I-a)的化合物作为单一活性剂或将化学式(I-a)的化合物与一个或多个其他治疗剂结合使用。一种确定样品中Btk存在的方法,包括将样品与化学式(I-a)的化合物或其形式接触,在允许检测Btk活性的条件下,检测样品中Btk活性的水平,并从中确定样品中Btk的存在或不存在。
