  摘要：

  Xa因子是一种丝氨酸蛋白酶，处于凝血级联的内在和外在途径之间的关键时刻。抑制因子Xa有可能为静脉和动脉血栓形成提供有效的治疗。我们最近描述了一系列间位取代的苯基吡唑类，它们是高效，选择性和口服生物利用因子Xa抑制剂。在本文中，我们报告了我们为进一步优化Xa因子抑制剂与一系列邻位和/或对位取代的苯基吡唑衍生物的选择性而做出的努力。最有效的化合物显示出Xa因子的亚纳摩尔抑制常数，并且对其他丝氨酸蛋白酶的选择性超过1000倍。这些化合物在动静脉分流血栓形成的兔子模型中也是有效的。

  The arylation of pyrazole and derivatives can be achieved by coupling arenediazonium species (formed in situ from anilines) by using a catalytic system that employs low‐toxicity and inexpensive copper metal under very mild and ligand‐free conditions (T=20 °C). From other nitrogen heterocycles, the presence of an additive (NBu4I) significantly improves the efficiency of the catalytic system. These results

  chromone derivatives containing substituted pyrazole were designed and synthesized. Preliminary bioassays showed that most of the synthesized compounds exhibited good nematicidal activity in vivo against Meloidogyne incognita at 10 mg/L. Among the tested compounds, A10 and A11 exhibited 100% inhibition rates. In addition, the molecular docking results indicated that both compound A10 and A11 interacts

  epigenetic component include DNA methylation and histone modifications. Acetylation of histones is controlled by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Imbalance of these two enzymatic systems is known to be a key factor in tumor progression. Because HDACs have been found to function incorrectly in cancer, various HDAC inhibitors (HDACIs) are being investigated to act as cancer

  遗传异常通常被认为是癌症的标志。但是，最近的研究表明，表观遗传机制也与癌症的发生和发展有关。表观遗传成分的模式包括DNA甲基化和组蛋白修饰。组蛋白的乙酰化受组蛋白乙酰转移酶（HATs）和组蛋白脱乙酰基酶（HDACs）控制。已知这两种酶系统的失衡是肿瘤进展的关键因素。由于已经发现HDAC在癌症中的功能不正确，因此正在研究各种HDAC抑制剂（HDACI）作为癌症的化学治疗剂。在这里，我们报告综合 一系列以N1-芳基或N1-H吡唑核为表面识别基序和肉桂酰基为与异羟肟酸锌结合基团（ZBG）连接的异羟肟酸基HDACI的对接研究和生物学活性。一些测试的化合物在微摩尔浓度下均表现出对HDAC的抑制特性和对神经母细胞瘤SH-SY5Y肿瘤细胞系的抗增殖活性。
