  Design, Synthesis, and Antitumor Evaluation of 4-Amino-(1H)-pyrazole Derivatives as JAKs Inhibitors

  摘要：

  Abnormalities in the JAK/STAT signaling pathway lead to many diseases such as immunodeficiency, inflammation, and cancer. Herein, we designed and synthesized a series of 4-amino-(1H)-pyrazole derivatives as potent JAKs inhibitors for cancer treatment. Results from in vitro protein kinase inhibition experiments indicated that compounds 3a-f and 11b are potent JAKs inhibitors. For example, the IC50 values of compound 3f against JAK1, JAK2, and JAK3 were 3.4, 2.2, and 3.5 nM, respectively. In cell culture experiments, compound 3f showed potent antiproliferative activity against various cell lines (PC-3, HEL, K562, MCF-7, and MOLT4) at low micromolar levels, while compound 11b showed selective cytotoxicity at submicromolar levels against HEL (IC50: 0.35;, mu M) and K562 (IC50: 0.37 mu M) cell lines. It is worth noting that both 3f and 11b showed more potent antiproliferative activities than the approved JAKs inhibitor Ruxolitinib.

  structure activity relationships, all derivatives were tested for their antibacterial activities against Escherichia coli and Staphylococcus aureus via Kirby–Bauer assays and minimum inhibitory concentration assays. Eight of the most potent compounds against S. aureus and E. coli were also screened against one strain of methicillin-resistant S. aureus (MRSA), Staphylococcus epidermidis and Salmonella typhimurium
