Bruton’s tyrosine kinase (BTK) inhibitors suppressing the aberrant activation of BTK have led to a paradigm shift in the therapy of B-cell malignancies. However, there is an urgent need to discover more selective covalent BTK inhibitors owing to the off-target adverse effects of the approved inhibitor, ibrutinib. Herein, we disclose the discovery and preliminary activity studies of novel BTK inhibitors carrying 1-amino-1H-imidazole-5-carboxamide as a hinge binder. The most potent BTK inhibitor 26 demonstrates impressive selectivity, favorable pharmacokinetic properties, and robust antitumor efficacy in vivo, which indicates its potential as a novel therapeutic option for B-cell lymphomas. Importantly, to the best of our knowledge, this is the first example of a 1-amino-1H-imidazole-5-carboxamide scaffold used as the hinge binder of kinase inhibitors, which will largely expand the chem. diversity of kinase inhibitors.

Liang, Yuru;Zhang, Mao;Zhou, Pengfei;Liu, Mingming;Li, Jianqi;Wang, Yang research published 《 Design, synthesis and antitumor evaluation of novel chiral diaryl substituted azetidin-2-one derivatives as tubulin polymerization inhibitors》, the research content is summarized as follows. A novel class of diaryl substituted azetidin-2-one derivatives were designed, asym. synthesized, and evaluated for antiproliferative activities. The in vitro antitumor assay revealed that among the 4-aryl-substituted 1-(3,4,5-trimethoxyphenyl)azetidin-2-ones (B series), most possessed moderate to strong activities, with compound B7c that bears a 2-naphthyl substituent being the most potent one (IC50 0.16-0.40 μM) against a panel of human cancer cell lines. In contrast, none of the 3-(arylmethylene)-substituted 1-(3,4,5-trimethoxyphenyl)azetidin-2-ones (L series) showed significant activities in the assay. Further studies indicated that B7c inhibited tubulin polymerization, disrupted in vitro vascularization, blocked cell cycle progression at G2/M phase, induced cell apoptosis, decreased mitochondrial membrane potential, and increased the intracellular reactive oxygen species level in a dose-dependent way. Compound B7c also inhibited significantly tumor growth in a xenograft mice model with no obvious drop in the mice body weights Collectively, these results suggested that B7c and its analogs should merit further investigation as new promising antitumor agents.
