  Concurrent inhibition of Janus kinase (JAK) and histone deacetylase (HDAC) could potentially improve the efficacy of the HDAC inhibitors in the treatment of cancers and resolve the problem of HDAC inhibitor resistance in some tumors. Here, a novel series of pyrimidin-2-amino-pyrazol hydroxamate derivatives as JAK and HDAC dual inhibitors was designed, synthesized, and evaluated, among which 8m possessed

  同时抑制Janus激酶（JAK）和组蛋白去乙酰化酶（HDAC）可能会提高HDAC抑制剂在癌症治疗中的疗效，并解决一些肿瘤中HDAC抑制剂耐药的问题。在这里，设计、合成和评估了一系列新的嘧啶-2-氨基-吡唑异羟肟酸酯衍生物作为 JAK 和 HDAC 双重抑制剂，其中 8m 对 JAK2 和 HDAC6 具有强效和平衡的活性，其半数最大抑制浓度为纳摩尔级。8m 在几种血液细胞系中表现出优于 SAHA 和鲁索替尼的抗增殖和促凋亡活性。值得注意的是，在携带 JAK2V617F 突变的 HEL 细胞中，8m 表现出比 SAHA 和鲁索替尼的组合更有效的抗增殖作用。小鼠药代动力学研究表明，8m 腹腔给药后具有良好的生物利用度。最后，8m 在 HEL 异种移植模型中显示出抗肿瘤功效且无显着毒性。总的来说，结果证实了 JAK 和 HDAC 双重抑制剂在血液系统恶性肿瘤中的治疗潜力，并为进一步的结构优化和抗肿瘤机制研究提供了有价值的线索。

  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.

  Cyclin-dependent kinases (CDKs) are promising therapeutic targets for cancer therapy. Herein, we describe our efforts toward the discovery of a series of 5-chloro-N-4-phenyl-N-2(pyridin-2-yl)pyrimidine-2,4-diamine derivatives as dual CDK6 and 9 inhibitors. Intensive structural modifications lead to the identification of compound 66 as the most active dual CDK6/9 inhibitor with balancing potency against these two targets and good selectivity over CDK2. Further biological studies revealed that compound 66 was directly bound to CDK6/9, resulting in suppression of their downstream signaling pathway and inhibition of cell proliferation by blocking cell cycle progression and inducing cellular apoptosis. More importantly, compound 66 significantly inhibited tumor growth in a xenograft mouse model with no obvious toxicity, indicating the promising therapeutic potential of CDK6/9 dual inhibitors for cancer treatment. Therefore, the above results are of great importance in the development of dual CDK6/9 inhibitors for cancer therapy.

  A series of novel 2,4-diaminopyrimidines containing piperidine and piperazine moieties were synthesized via an efficient one-pot methodology. The bioassay tests demonstrated that compounds 27 and 28 displayed much stronger antitumor activities against four human cancer cell lines (HepG2, A549, MDA-MB-231 and MCF-7) than positive control fluorouracil. Particularly, compound 28 showed a two-fold improvement compared to fluorouracil in inhibiting MDA-MB-231 and A549 cell proliferation with IC50 values of 7.46 and 12.78 μM, respectively. Further flow-activated cell sorting analysis revealed that the most promising compound 28 displayed a significant effect on G2/M cell-cycle arrest in a dose-dependent manner in MDA-MB-231 cells.
