Novel pyrazole-5-carboxamide and pyrazole–pyrimidine derivatives: Synthesis and anticancer activity
摘要:
A series of novel pyrazole-5-carboxamide and pyrazole-pyrimidine derivatives were designed and synthesized. All compounds have been screened for their antiproliferative activity against MGC-803, SGC-7901 and Bcap-37 cell lines in vitro. The results revealed that compounds 8a, 8c and 8e exhibited strong inhibitory activity against MGC-803 cell line. The flow cytometric analysis result showed that compound 8e could inhibit MGC-803 proliferation. Some title compounds were tested against telomerase, and compound 8e showed the most potent inhibitory activity with IC50 value at 1.02 +/- 0.08 mu M. The docking simulation of compound 8e was performed to get the probable binding model, among them, LYS 189, LYS 372, LYS 249 and ASP 254 may be the key residues for the telomerase activity.

Abstract Four series of total 35 newpyrazolo[4,3-d]pyrimidine compounds were designed, synthesized and evaluated for their inhibitory activity against LPS-induced NO production in RAW264.7 macrophages. Among them, compound 4e was found to be the most potent inhibitor, which decreased the production of cytokines in vitro, such as NO, IL-6 and TNF-α, with IC50 values of 2.64, 4.38 and 5.63 μM, respectively
抽象的 设计,合成并评估了总共35种新的吡唑并[4,3- d ]嘧啶化合物的四个系列,它们对RAW264.7巨噬细胞中LPS诱导的NO产生的抑制活性。其中,化合物4e被认为是最有效的抑制剂,可降低体外细胞因子的生成,例如NO,IL-6和TNF-α,IC 50值分别为2.64、4.38和5.63μM。进一步的研究表明,化合物4e通过抑制TLR4 / p38信号通路抑制巨噬细胞的细胞因子分泌。此外,化合物4e在体内显示LPS诱导的急性肺损伤模型中的抗炎活性。这些数据表明,化合物4e可能是用于治疗ALI的有前途的先导结构。

structure-activity relationships, four series (A-D) of total 90 new pyrazolo[4,3- d]pyrimidine compounds were designed and synthesized. All the compounds have been tested for their anti-inflammatory activities by inhibiting of LPS-induced NO production. A clear structure-activity relationship has been concluded step by step, and finally 3,4,5-trimethoxystyryl-1 H-pyrazolo[4,3- d]pyrimidine was found to be the most
