  Development of 3-aryl-1-isoquinolinamines as potent antitumor agents based on CoMFA

  摘要：

  Various substituted 3-aryl-1-isoquinolinamines were designed and synthesized based on the previously constructed CoMFA model. Most of the synthesized compounds showed excellent potency in eight different human tumor cell lines as expected. In order to find the exact cytotoxic mechanism of these 3-aryl-1-isoquinolinamines, we analyzed the cell cycle dynamics by flow cytometry and found that 3-aryl-1-isoquinolinamine 6k-treated HeLa cells were arrested in G2/M phase, which is related to apoptosis.

• Antiviral Activity of Isoquinolone Derivatives against Influenza Viruses and Their Cytotoxicity

  Influenza viruses are one of the major causative agents for human respiratory infections. Currently, vaccines and antivirals approved for preventing and treating viral infections are available. However, limited protection efficacy and frequent emergence of drug-resistant viruses stand for a need for the development of antivirals with different chemical skeletons from existing drugs. Screening of a chemical library identified an isoquinolone compound (1) as a hit with 50% effective concentrations (EC50s) between 0.2 and 0.6 µM against the influenza A and B viruses. However, it exhibited severe cytotoxic effects with a 50% cytotoxic concentration (CC50) of 39.0 µM in canine kidney epithelial cells. To address this cytotoxic issue, we synthesized an additional 22 chemical derivatives. Through structure-activity, as well as structure-cytotoxicity relationship studies, we discovered compound 21 that has higher EC50 values ranging from 9.9 to 18.5 µM, but greatly alleviated cytotoxicity with a CC50 value over 300 µM. Mode-of-action and cell type-dependent antiviral experiments indicated that it targets viral polymerase activity and functions also in human cells. Here, we present a new class of viral polymerase inhibitors with a core skeleton of isoquinolone, of which antiviral activity could be better improved through following design and synthesis of its derivatives for drug development.

  流感病毒是人类呼吸道感染的主要致病因子之一。目前，已经批准用于预防和治疗病毒感染的疫苗和抗病毒药物已经问世。然而，现有药物的保护效果有限，且药物耐药病毒频繁出现，因此需要开发具有与现有药物不同化学骨架的抗病毒药物。对化学库的筛选确定了一种异喹啉类化合物（1）作为对甲型和乙型流感病毒的50%有效浓度（EC50）在0.2至0.6微米之间的抑制剂。然而，它在犬肾上皮细胞中表现出严重的细胞毒性效应，其50%细胞毒性浓度（CC50）为39.0微米。为解决这一细胞毒性问题，我们合成了另外22种化学衍生物。通过结构活性以及结构-细胞毒性关系研究，我们发现化合物21具有更高的EC50值，范围在9.9至18.5微米之间，但细胞毒性明显减轻，其CC50值超过300微米。作用模式和细胞类型相关的抗病毒实验表明，它靶向病毒聚合酶活性，同时在人类细胞中也发挥作用。在这里，我们提出一类具有异喹啉核心骨架的病毒聚合酶抑制剂，其抗病毒活性可以通过后续设计和合成其衍生物以用于药物开发而得到更好的改进。

  A triflic acid (TfOH) mediated sequential cyclization of ortho-alkynylarylesters and ammonium acetate (NH4OAc) was reported. The reaction took place via a Brønsted acid-mediated intramolecular cyclization of ortho-alkynylarylesters followed by an ammonium acetate participated substitution reaction, forming isoquinolin-1-ones as the major products. Different from most of the known synthetic methods

  报道了三氟乙酸（TfOH）介导的邻炔基芳基酯和乙酸铵（NH 4 OAc）的顺序环化。该反应通过布朗斯台德酸介导的邻位分子内环化反应进行-炔基芳基酯接着乙酸铵参与取代反应，形成异喹啉-1-酮为主要产物。与大多数已知的异喹啉-1-酮合成方法不同，所报道的反应不需要金属催化剂。在少数情况下，获得了区域异构体–异吲哚啉-1-酮与异喹啉-1-酮。还分离了中间体化合物-异色酮-1-酮和异苯并呋喃-1-酮。相互转化实验表明，在布朗斯台德酸诱导的邻炔基芳基酯分子内环化过程中形成的区域异构体。采用这种新方法，可以以中等收率制备天然产物ruprechstyril。

  A dramatic substituent effect was found in the silver(I)-catalyzed cyclization reaction of ortho-alkynylaryl aldehyde oxime derivatives. When R is an alkyl group, the Ag(I)-catalyzed reaction in dimethylacetamide at 110 °C (conditions A) affords isoquinolines in good to excellent yields, in contrast, isoquinolin-1(2 H)-ones were produced in moderate to high yields under conditions B (dimethylformamide
