Twoseries of novel chromone derivatives were synthesized and investigated for their ability to inhibit the activity of monoamine oxidase. The SAR data indicate that chromone derivatives with substituents in position 3 of γ-pyrone nucleus act preferably as MAO-B inhibitors, with IC50 values in the nanomolar to micromolar range. Almost all chromone 3-carboxamides display selectivity toward MAO-B. Identical
合成了两种新的色酮衍生物,并研究了它们抑制单胺氧化酶活性的能力。SAR数据表明,在γ-吡喃酮核的3位具有取代基的色酮衍生物优选用作MAO-B抑制剂,IC 50值在纳摩尔至微摩尔范围内。几乎所有色酮3-羧酰胺均显示出对MAO-B的选择性。上在两种同种型(色酮类的活性完全丧失的γ吡喃酮核结果2位置是相同的取代2 - 12除了3和5)。显色酮(19)表现出MAO-B IC 50具有63 nM的选择性,是MAO-A的1000倍以上,并且具有拟可逆性抑制剂的作用。对接活性最高的化合物的MAO结合的实验突出显示了同工型A和B之间的不同相互作用方式。色酮异构体之间的溶剂化作用的差异分析提供了有关3取代色酮衍生物优越轮廓的更多见解。
Discovery of novel A3 adenosine receptor ligands based on chromone scaffold
has been developed. Accordingly, twoseries 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

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

We report a novel Lewis acid catalysed tandem reaction of isocyanides, chromone 3-carboxylic acid and nucleophiles. An experimentally very simple procedure, involving the use of microwave irradiation in the presence of a Lewis acid catalyst, affords a representative collection of chromone-2-carboxamides and chromone-2-carboxamido-3-esters in high yields, in just a few minutes. Such an unprecedented
