Not widely distributed in nature, aurones, (Z)-2-benzylidene-benzofuran-3(2H)-ones, are one of the less common and lesser-known representatives of a flavonoid subclass. Nevertheless, they exhibit a strong and broad variety of biological activities. We have combined the benzofuranone part of a classical aurone with either a chromone or a coumarin scaffold which proved to feature interesting biological activities including antimicrobial, antiviral, anticancer, anti-inflammatory and antioxidant properties. Herein we present a series of 26 novel benzofuran derivatives with the first biological results in K562 human leukemia cells showing that compounds 21b, 29b and 29c are able to induce around 24% apoptosis.
在自然界中并不广泛分布的黄烷酮(Z)-2-苯甲亚基-苯并呱-3(2H)-酮,是一种不太常见且知之甚少的黄酮亚类代表。尽管如此,它们表现出强烈且广泛的生物活性。我们将经典黄烷酮的苯并呱部分与色烯或香豆素骨架结合,结果显示出有趣的生物活性,包括抗菌、抗病毒、抗癌、抗炎和抗氧化特性。在此,我们呈现一系列26种新型苯并呱衍生物,首次在K562人类白血病细胞中的生物学结果表明,化合物21b、29b和29c能诱导约24%的细胞凋亡。
