  Drug Discovery against Psoriasis: Identification of a New Potent FMS-like Tyrosine Kinase 3 (FLT3) Inhibitor, 1-(4-((1H-Pyrazolo[3,4-d]pyrimidin-4-yl)oxy)-3-fluorophenyl)-3-(5-(tert-butyl)isoxazol-3-yl)urea, That Showed Potent Activity in a Psoriatic Animal Model

  摘要：

  Psoriasis is a chronic T-cell-mediated autoimmune disease, and FMS-like tyrosine kinase 3 (FLT3) has been considered as a potential molecular target for the treatment of psoriasis. In this investigation, structural optimization was performed on a lead compound, 1-(4-(1H-pyrazolo[3,4-d]pyrimidin-4-yloxy)phenyl)-3-(4-chloro-3-(trifluoromethyl)phenyl)urea (1), which showed a moderate inhibitory activity againt FLT3. A series of pyrazolo[3,4-d]pyrimidine derivatives were synthesized, and structureactivity relationship analysis led to the discovery of a number of potent FLT3 inhibitors. One of the most active compounds, 1-(4-(1H-pyrazolo[3,4-d]pyrimidin-4-yloxy)-3-fluorophenyl)-3-(5-tert-butylisoxazol-3-yl)urea (18b), was then chosen for in-depth antipsoriasis studies because this compound displayed the highest potency in a preliminary antipsoriasis test. Compound 18b exhibited significant antipsoriatic effects in the K14-VEGF transgenic mouse model of psoriasis, and no recurrence was found 15 days later after the last administration. Detailed mechanisms of action of compound 18b were also investigated. Collectively, compound 18b could be a potential drug candidate for psoriasis treatment.

  发现吡咯并[2,3-d]嘧啶衍生物作为有效和选择性的集落刺激因子 1 受体激酶抑制剂

  摘要：

  集落刺激因子 1 受体激酶 (CSF1R) 在肿瘤相关巨噬细胞复极化中发挥着不可或缺的作用，并已成为癌症免疫治疗的新治疗靶点。大多数当前的 CSF1R 激酶抑制剂在 CSF1R 激酶和其他 III 型生长因子受体成员之间缺乏选择性。在此，我们报告了一种有效的选择性 CSF1R 抑制剂18h，其对 CSF1R 的 IC 50值为 5.14 nM，并且比其他 III 型受体酪氨酸激酶具有选择性（>38 倍）。18小时抑制 RAW264.7、THP-1 和 M-NFS-60 细胞中 CSF1R 的磷酸化及其下游信号通路。用这种化合物处理会导致 RAW264.7 巨噬细胞中巨噬细胞极化以剂量依赖性方式发生改变。在体内，18h显示出可接受的药代动力学特征，并在接种 M-NFS-60 细胞的小鼠异种移植模型中抑制肿瘤生长。

  We describe the structural optimization of a hit compound, 1-(4-(1H-pyrazolo[3,4-d]pyrimidin-4-ylamino)phenyl)-3-(3-methoxyphenyl)urea (1), which exhibits inhibitory activity but low potency against FLT3 and VEGFR2. A series of pyrazolo [3,4-d]pyrimidine derivatives were synthesized, and structure-activity relationship analysis using cell- and transgenic-zebrafish-based assays led to the discovery of a number of compounds that exhibited both high potency against FLT3-driven human acute myeloid leukemia (AML) MV4-11 cells and a considerable antiangiogenic effect in transgenic-zebrafish-based assays. The compound 1-(4-(1H-pyrazolo[3,4-d]pyrimidin-4-yloxy)phenyl)-3-(4-chloro-3-(trifluoromethyl)phenyl)urea (33), which exhibited the highest activity in preliminary in vivo anti-AML assays, was chosen for further anti AML studies. The results demonstrated that compound 33 is a multikinase inhibitor that potently inhibits FLT3 and VEGFR2. In an MV4-11 xenograft mouse model, a once daily dose of compound 33 at 10 mg/kg for 18 days led to complete tumor regression without obvious toxicity. Western blot and immunohistochemical analyses were performed to determine the mechanism of action of compound 33.
