制备方法与用途

氨基吡啶及其衍生物 用途

氨基吡啶是一种重要的精细化工中间体，广泛应用于医药和农药等领域。其中，2-氨基-4-氰基吡啶作为mGluR2拮抗剂，可用于治疗中枢神经系统疾病。

合成方法

合成2-氨基-4-氰基吡啶的方法多样：

1. 以2-氨基吡啶为原料，依次经过氮氧化反应、硝化反应、氨基保护、还原反应、席曼反应以及氨基脱保护反应制备。此路线涉及多个危险的化学反应步骤，且合成路径较长，总收率较低。

2. 另一种方法是使用2-氯-4-氰基吡啶为起始物料与氨水发生氨解反应来制备目标化合物。

3. 还可以采用2-硝基-4-氰基吡啶经铁粉还原的方法进行合成。

• Fragment-to-Hit-to-Lead Discovery of a Novel Pyridylurea Scaffold of ATP Competitive Dual Targeting Type II Topoisomerase Inhibiting Antibacterial Agents

  The discovery and optimization of a new class of bacterial topoisomerase (DNA gyrase and topoisomerase IV) inhibitors binding in the ATP domain are described. A fragment molecule, 1-ethyl-3-(2-pyridyl)urea, provided sufficiently potent enzyme inhibition (32 μM) to prompt further analogue work. Acids and acid isosteres were incorporated at the 5-pyridyl position of this fragment, bridging to a key asparagine

  描述和发现了一种新型的结合在ATP域中的细菌拓扑异构酶（DNA促旋酶和拓扑异构酶IV）抑制剂。片段分子1-乙基-3-（2-吡啶基）脲提供了足够强的酶抑制作用（32μM），可促进进一步的类似工作。在该片段的5-吡啶基位置掺入了酸和酸等排体，桥接至关键的天冬酰胺残基，改善了酶抑制作用，并产生了可测量的抗菌活性。由于有利的亲脂性相互作用，在4-吡啶基位置的CF 3-噻唑取代基改善了抑制能力。与革兰氏阳性病原体金黄色葡萄球菌和肺炎链球菌相比，具有良好的抗菌活性和革兰氏阴性病原流感嗜血杆菌和卡他莫拉菌。前体代谢物的掺入和突变分析研究支持双分子拓扑异构酶抑制作用的作用方式，DNA合成的阻断。化合物35在小鼠金黄色葡萄球菌疾病模型中是有效的，其中证明了菌落形成单位相对于对照减少了4.5个对数。

  A visible-light-induced direct C–H alkylation of imidazo[1,2-a]pyridines has been developed. It proceeds at room temperature by employing inexpensive Eosin Y as a photocatalyst and alkyl N-hydroxyphthalimide (NHP) esters as alkylation reagents. A variety of NHP esters derived from aliphatic carboxylic acids (primary, secondary, and tertiary) were tolerated in this protocol, giving the corresponding
