Bcr-Abl plays an essential role in the pathogenesis and development of chronic myeloid leukaemia (CML). Inhibition of Bcr-Abl has great potential for therapeutic intervention in CML. In order to obtain novel and potent Bcr-Abl inhibitors, twenty seven 4,6-disubstituted pyrimidines were synthesized and evaluated herein. The biological results indicated that four compounds of them (C4, C5, C16, and C23) were potent Bcr-Abl inhibitors which were comparable to positive control. Moreover, C4 and C5 displayed promising antiproliferative activity against K562 cells. The results suggested that these 4, 6-disubstituted pyrimidines could serve as promising leads for further optimization of Bcr-Abl inhibitors. (C) 2014 Elsevier Ltd. All rights reserved.

further structure-guided optimization and structure–activityrelationship (SAR) study of this scaffold, resulting in compound 30, which retained biochemical and cellular potency, while demonstrating a significantly improved selectivity profile. Furthermore, we confirm that the inhibitors show efficient binding affinity in the context of HEK 293T cells using isothermal CETSA methods. Taken together, compound
