  色酮-2-羧酰胺衍生物作为细胞毒剂和5-脂氧合酶抑制剂的合成与评价

  摘要：

  在本研究中，我们制备了一系列具有多种酰胺侧链的21色酮羧酰胺衍生物。使用MTT分析法在体外评估了它们抑制乳腺癌（MCF-7），卵巢癌（OVCAR和IGROV）和结肠癌（HCT-116）癌细胞系增殖的能力。在这些化合物中，有13种显示出对至少一种癌细胞的有希望的细胞毒活性，其IC 50为0.9-10μM。还筛选了我们的化合物作为5-脂氧合酶的抑制剂的抗炎活性。对色酮羧酰胺衍生物的结构-活性关系研究表明，色酮核（R 1）或丙基上存在6-氟取代基酰胺侧链上的3-乙基苯基（R 2）对细胞毒性活性有积极影响。就抗炎活性而言，亲水性色酮羧酰胺衍生物表现出更大的5-脂氧合酶抑制作用。色酮羧酰胺的理化性质符合药物开发过程的一般要求，配体效率值可进一步优化化合物结构。4b作为线索。

  has been developed. Accordingly, two series of novel chromone carboxamides placed at positions C2 (compounds 2-13) and C3 (compounds 15-26) of the gamma-pyrone ring were synthesized using chromone carboxylic acids (compounds 1 or 14) as starting materials. From this study and on the basis of the obtained structure-activity relationships it was concluded that the chromone carboxamide scaffold represent

  已经开发了一个致力于发现新化学实体（NCE）作为AR配体的项目，该配体包含苯并-γ-吡喃酮[（4H）-1-苯并吡喃-4-酮]子结构。因此，使用色酮羧酸（化合物1或14）作为起始原料，合成了位于γ-吡喃酮环的位置C2（化合物2-13）和C3（化合物15-26）的两个新的色酮羧酰胺系列。从这项研究中，并在获得的结构-活性关系的基础上，得出的结论是，色酮羧酰胺支架代表了一类新型的AR配体。最显着的色酮是对A3AR表现出更好亲和力的化合物21和26（分别为Ki = 3680 nM和Ki = 3750 nM）。受体驱动的分子建模研究提供了有关色酮的结合/选择性数据的信息。

  assess two series of chromones-based compounds as possible ligands for PqsR, a LuxR-type receptor. Most compounds showed good predicted affinities for PqsR, higher than the PQS native ligand. Encouraged by these docking results, we synthesized a library of 34 direct and 25 retro chromone carboxamides using two optimized routes from 2-chromone carboxylic acid as starting material for both series. We evaluated

  Microwave irradiation offers a considerable advantage over conventional synthesis with rate enhancements and cleaner reactions. Accordingly, a new microwave-assisted method for the synthesis of functionalized chromones was developed allowing the obtention of a library of chromone carboxamides. The method has been shown to present several advantages including operational simplicity, good performance, significant reduction in reaction time, less formation of by-products, and easier work-up.

  Monoamine oxidase (MAO) is an enzyme, present in mammals in two isoforms MAO-A and MAO-B. These isoforms have a crucial role in neurotransmitters metabolism, representing an attractive drug target in the therapy of neurodegenerative diseases (MAO-B) and depression (MAO-A). In this context, our work has been focused on the discovery of new chemical entities (NCEs) for MAO inhibition, based on the development of chromone carboxamides. Chromone derivatives with a carboxamide function located in position 2- and 3- of the benzo-gamma-pyrone core, (compounds 2-6 and 8-12) were synthesized, with moderate/good yields, by a one-pot condensation reaction using phosphonium salts as coupling reagents. The synthetic compounds were screened towards human MAO isoforms (hMAO) to evaluate their potency and selectivity. The chromone-3-carboxamides show high selectivity to hMAO-B, with compounds 9 and 12 displaying IC50 values at nanomolar range. (C) 2010 Published by Elsevier Ltd.
