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
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。
