    喹啉抗叶酸胸苷酸合酶抑制剂:C2-和C4-取代基的变异。
    摘要:
    强大的胸苷酸​​合酶(TS)抑制剂N- [4- [N-[(2-氨基-3,4-二氢-4-氧代-6-喹唑啉基)甲基] -N-prop-对双环系统的修饰2-炔基氨基]苯甲酰基] -L-谷氨酸(1,CB3717)已导致合成了一系列在C2和C4位带有多个取代基的喹啉抗叶酸酯。通常,合成途径包括将适当的N- [4-(丙-2-炔丙基氨基)苯甲酰基] -L-谷氨酸二乙酯与二取代的6-(溴甲基)喹啉偶联,然后使用弱碱将其脱保护。测试了该化合物作为部分纯化的L1210 TS的抑制剂。作为细胞毒性的量度,测试了化合物对培养物中L1210细胞生长的抑制作用。发现含有氯,氨基,在C2位的甲基取代基或在C4位的氯或溴取代基。改变2h N10取代基对酶的抑制作用与在含喹唑啉酮的叶酸中观察到的相似,表明喹啉化合物可能以与喹唑啉酮类似的方式与酶相互作用。同样,将2'-氟取代基引入几种喹啉类抗叶酸剂的苯甲酰基环中会导致TS抑

    Facile synthesis of 4-quinolone derivatives via one-pot cascade reaction under transition-metal-free conditions
    摘要:
    A practical and efficient strategy has been described for the preparation of 4-quinolone derivatives. Using commercially available diethyl acetylenedicarboxylate and aromatic amines as starting materials, the synthetic protocol has been achieved and afforded the product via hydroamination at room temperature followed by PPA-catalyzed intramolecular ring closure. The products can be easily obtained in high yields. Conditions and mechanism of the reaction have also been investigated. This protocol is environmentally friendly and transition-metal-free, with advantages including short reaction time, convenient operation, and mild reaction conditions. (C) 2015 Elsevier Ltd.

  • Quinoline 2 carboxylic acids used in metal extraction processes

    Quinoline-2-carboxylic acids having in the 4-position a halogen atom or an optionally substituted hydrocarbyl group attached through an oxygen atom, optionally substituted by a hydrocarbyl group in the 3 position and optionally substituted in any of the 5, 6, 7 and 8 positions by halogen atoms, nitro or cyano groups, or optionally substituted hydrocarbyl groups each attained directly or through an oxygen atom, and containing in the substituents in the 3, 4, 5, 6, 7 and 8 positions a total of at least 3 carbon atoms form complexes with metals, especially copper. These complexes may be extracted by organic solvents from aqueous solutions of metal salts treated with the quinoline-2-carboxylic acids. The quinoline-2-carboxylic acids may be prepared from the corresponding 4-hydroxy compounds by (a) treating with a phosphorus halide, if necessary reacting the product with the alkali metal derivative of an alcohol or phenol and hydrolysing the ester group or (b) treating with a hydrocarbyl halide in presence of a base.

    many esters and amide derivatives of KYNA are synthesized via coupling reaction or multi-step synthesis using different organic or metallic catalysts. Herein, we developed a novel one-pot, catalyst-free, convenient synthesis of KYNA ethyl esters using aniline and diethyl acetylene dicarboxylate in DMF under heating. We also explored the synthesis of KYNA and KYNA amide derivative in a simple manner with
    犬尿酸 (KYNA) 是一种内源性分子,是离子型谷氨酸受体的非选择性拮抗剂,已被发现具有神经保护活性。KYNA 补充剂可能适用于治疗神经退行性疾病,但由于其极性性质,它不能穿过血脑屏障。因此,其不同的酯和酰胺衍生物被探索作为前药,可以穿过血脑屏障并原位转化为KYNA。然而,KYNA的许多酯和酰胺衍生物是使用不同的有机或金属催化剂通过偶联反应或多步合成合成的。在此,我们开发了一种新型的一锅法、无催化剂、方便地合成 KYNA 乙酯的方法,使用苯胺和乙炔二甲酸二乙酯在 DMF 中加热。我们还探索了以简单的方式合成 KYNA 和 KYNA 酰胺衍生物,分别通过水解和缩合获得了良好的收率。
