本研究旨在寻找黄酮化合物的抗肿瘤活性。评估这些化合物在体外对人类白血病(HL-60)和人类肝癌(SMMC-7721)细胞系的细胞毒性活性。
从海南杜鹃的空气部分中分离出八种天然黄酮类化合物(1-8),并使用简单的合成方法从天然产物matteucinol(1)获得了一系列修饰的黄酮类衍生物(9-18)。使用硫酸罗丹明B法评估这些黄酮类化合物的抗肿瘤抑制活性。
大多数化合物表现出良好的药理活性,并描述了初步的结构-活性关系。在本研究的黄酮类衍生物系列中,化合物3(2,3-二氢-5-羟基-7-甲氧基-2-(4-甲氧基苯基)-6,8-二甲基-4H-1-苯并吡喃-4-酮)和16(5-羟基-7,4'-二甲氧基-6,8-二甲基黄烷)对HL-60细胞系表现出强烈的抑制活性,IC50值分别为15.2和13.2微米。
对黄酮类衍生物的重新关注揭示了化合物3和16可能被视为新抗肿瘤剂的先导化合物。我们的结果不仅丰富了天然来源活性黄酮类化合物家族,而且鼓励合成黄酮类类似物以改善细胞毒性活性。
The aim of this study was to search for antitumour activity of flavonoid compounds. The cytotoxic activity of these compounds in vitro was evaluated against the human leukaemia (HL-60) and human hepatoma (SMMC-7721) cell lines.
Eight natural flavonoids (1–8) were isolated from the aerial parts of Rhododendron hainanense and a series of modified flavonoid derivatives (9–18) were obtained from the natural product matteucinol (1), using simple synthetic methods. Antitumour inhibitory activity of these flavonoids was assessed using the sulforhodamine B method.
Most of the compounds exhibited good pharmacological activity and the preliminary structure–activity relationships were described. Within the series of flavonoid derivatives in this study, compounds 3 (2,3-dihydro-5-hydroxy-7-methoxy-2-(4-methoxyphenyl)-6,8-dimethyl-4H-1-benzopyran-4-one) and 16 (5-hydroxy-7, 4′-dimethoxy-6, 8-dimethylflavan) exhibited strong inhibitory activity against the HL-60 cell line with IC50 values (the drug concentration that resulted in a 50% reduction in cell viability or inhibition of the biological activity) of 15.2 and 13.2 µm, respectively.
Renewed attention to flavonoid derivatives revealed the possibility that compounds 3 and 16 could be considered as lead compounds for the development of new antitumour agents. Our results have not only enriched the family of active flavonoids from natural sources, but have encouraged the synthesis of flavonoid analogues for improving cytotoxic activity.
