acetylcholinesterase inhibitoryactivity as well as hepatotoxicity using tacrine as a reference standard. The obtained results revealed that most of the compounds comprising a chloro substituent displayed higher activity when compared with the other analogs. Among the newly synthesized compounds, four analogs displayed in vitro and in vivo acetylcholinesterase inhibitoryactivity comparable to or slightly

Liver cancer is the most common type of cancer in many countries. New studies and statistics show rising liver cancer worldwide, so it is essential to seek newagents for this type of cancer. PIM1 has an attractive target in the discovery of cancer medications as it is very much expressed in a variety of malignancies and influences such as tumorigenesis, cell cycle progression, cellular proliferation
肝癌是许多国家最常见的癌症类型。新的研究和统计数据显示,全球肝癌呈上升趋势,因此寻找治疗此类癌症的新药物至关重要。PIM1 在癌症药物的发现中具有吸引人的目标,因为它在多种恶性肿瘤和影响(例如肿瘤发生、细胞周期进程、细胞增殖、细胞凋亡和细胞迁移)中大量表达。因此,合成了一系列吡啶酮和吡啶-酰胺并测试了抗肝癌活性。 在合成策略中,4,6-二芳基-3-氰基-2-吡啶酮3a-n使用一锅四组分合成方法合成。对 4,6-diphenyl-3-cayno-2-pyridone 3a进行结构修饰以增强活性。在K 2 CO 3存在下烷基化得到O-烷基化产物4-6。合成乙酰氧基酰肼7并环化成 1,3,4-恶二唑硫酮8,后者在硫上烷基化得到10。采用叠氮偶联法将2-(吡啶-2-基氧基)乙酰肼7与不同的胺和氨基酸酯偶联得到产物12a-e和13a-b。将合成的衍生物进行对HepG2和THLE-2细胞,细胞毒性化合

A series of 3‐cyano‐2‐pyridone derivatives were synthesized by one‐pot four‐component condensationreaction involving a benzaldehyde derivative, alkyl cyanoacetate, acyclic or cyclicketones, and ammonium acetate in reflux condition. The X‐ray structure of the products 5a and 5d confirm symmetric dimers via hydrogen bonding interactions between individual pyridine molecules showing, in addition, also

A versatile synthesis of 3‐cyano‐2‐pyridones via a one‐pot, four‐component condensation of ethyl cyanoacetate, ketones, aldehydes, and ammonium acetate under very mild conditions has been developed. This method provides rapid access to this type of valuable heterocyclic compounds from readily available materials in a single operation.
