    Bruton's tyrosine kinase (BTK) is a promising drug target for the treatment of multiple diseases, such as B-cell malignances, asthma, and rheumatoid arthritis. A series of novel aminotriazines were identified as highly selective inhibitors of BTK by a scaffold-hopping approach. Subsequent SAR studies of this series using two conformationally different BTK proteins, an activated form of BTK and an unactivated form of BTK, led to the discovery of a highly selective BTK inhibitor, 4b. With significant efficacy in models in vivo and good ADME and safety profiles, 4b was advanced into preclinical studies.
