  摘要：

  制备了一系列2-哌嗪基苯并咪唑衍生物，并将其评价为5-HT 3受体拮抗剂。通过放射性配体结合测定法评估了它们的5-HT3受体亲和力，并确定了它们在麻醉大鼠中抑制5-HT诱导的Bezold-Jarisch反射的能力。化合物7e（lerisetron，pKi = 9.2）对5-HT3受体的亲和力高于tropisetron和granisetron，而化合物7q（pKi = 7.5）对该受体的亲和力很低，表明苯并咪唑的N1原子被取代环对于亲和力和活性至关重要。还讨论了不同位置的多个取代基对苯并咪唑芳环的取代作用。建立了所研究化合物的5-HT3拮抗活性与芳香环上取代位置的强相关性。因此，尽管4-甲氧基衍生物7m显示出对5-HT 3受体的弱亲和力（pKi ＝ 6.7），但是7-甲氧基衍生物7n显示出最高的亲和力（pKi ＝ 9.4）。化合物7e和7n作为癌症化疗和放疗引起的恶心和呕吐的治疗药物，目前正在进一步研究中。

  Protein kinase CK2 is a highly pleiotropic protein kinase capable of phosphorylating hundreds of protein substrates. It is involved in numerous cellular functions, including cell viability, apoptosis, cell proliferation and survival, angiogenesis, or ER-stress response. As CK2 activity is found perturbed in many pathological states, including cancers, it becomes an attractive target for the pharma

  蛋白激酶CK2是高度多效性蛋白激酶，能够磷酸化数百种蛋白底物。它涉及许多细胞功能，包括细胞活力，凋亡，细胞增殖和存活，血管生成或ER应激反应。由于发现CK2活性在包括癌症在内的许多病理状态中受到干扰，因此它成为该药的有吸引力的靶标。已经开发了许多低质量的ATP竞争性抑制剂，其中大多数已被卤化。我们测试了六种系列卤代杂环配体的结合，这些配体衍生自可商购的4,5-二卤代苯-1,2-二胺。选择这些配体系列以使支架作用与直接归因于卤素原子存在的疏水相互作用分离。最初使用计算机分子对接技术来测试每种配体在CK2的ATP结合位点结合的能力。将HPLC衍生的配体疏水性数据与通过小体积差示扫描荧光法（nanoDSF）评估的结合亲和力进行比较。我们确定了三个有希望的配体支架，其中两个尚未被描述为CK2抑制剂，但可能导致有效的CK2激酶抑制剂。已经确定了在nanoDSF分析中被鉴定为最有前途的八种化合物对CK

To develop a broad-spectrum inhibitor of influenza to combat the problem of drug resistance, we previously identified the highly conserved E339...R416 salt bridge of the nucleoprotein trimer as a target and compound 1 as an inhibitor disrupting the salt bridge with an EC50 = 2.7 μM against influenza A (A/WSN/1933). We have further modified this compound via a structure-based
