Abstract

A series of 3-substituted pyrazolopyrimidine derivatives as Btk inhibitors were designed by structure-based drug design and they were synthesized, evaluated by enzyme-based assay and anti-proliferation against Ramos and Raji cells. Most of them displayed good inhibitory activities against both Btk and B-cell lymphoblastic leukemia lines in vitro. Among them, compound 8a exhibited excellent potency (IC50 = 7.95 nM against BTK Enzyme, 8.91 μM against Ramos cells and 1.80 μM against Raji cells), with a better hydrophilicity (ClogP = 3.33). These explorations provided new clues to discover 3-substituted pyrazolopyrimidine derivatives as novel anti-tumor agents.
