Detecting early-stage ovarian cancer, the fourth leading cause of cancerrelated
deaths in women, is difficult, and the development of novel chemotherapeutic
agents is required. Since several flavonoids show anticancer activities against ovarian cancer, 35 naphthylated flavonoids
including 3’,4’-naphthochalcones, 5’,6’-naphthochalcone, 7,8-nap-hthoflavones, 5,6-naphthoflavanones, 5,6-naphthoflavones,
2,3-naphthochalcone, N-phenylpyrazolyl-5’,6’-naphthocha-lcones, carbothioamidepyrazolyl-5’,6’-naphthochalcones,
pyrazolyl-3’,4’-naphthochalcone, and carbothioamidepyrazolyl-3’,4’-naphthochalcone were designed and synthesized.
To explore the anticancer effects of these compounds, clonogenic long-term survival assays were applied on human
cisplatin-resistant A2780/Cis ovarian cancer cells. Relationships between the structural properties of 35 naphthylated flavonoids
and their clonogenicities were explored using comparative molecular field analysis and hologram quantitative structure–
activity relationships. As a result, several structural features that increased cell growth inhibitory activity were identified, and
a compound satisfying these conditions, 5-(2,3-dimethoxyphenyl)-3-(1-hydroxynaphthalen-2-yl)-N-phenyl-4,5-dihydro-1Hpyrazole-
1-carbothioamide, was designed and synthesized. This novel compound´s half-maximal cell growth inhibitory concentration
was lower than those of the 35 flavonoid derivatives tested here. Therefore, the structural features observed in this
report can be used to design and develop potent chemotherapeutic agents to treat ovarian cancer cells.
早期卵巢癌的检测难度较大,而卵巢癌是女性癌症相关死亡的第四大原因,因此需要开发新型化疗药物。由于几种类黄酮显示出对卵巢癌的抗癌活性,本研究设计并合成了35种萘基类黄酮,包括3',4'-萘酮酮、5',6'-萘酮、7,8-萘黄酮、5,6-萘黄烷酮、5,6-萘黄酮、2,3-萘酮、N-苯基吡唑基-5',6'-萘酮、碳硫酰胺吡唑基-5',6'-萘酮、吡唑基-3',4'-萘酮及碳硫酰胺吡唑基-3',4'-萘酮。为了探索这些化합物的抗癌效果,采用了克隆形成长期存活实验,对人类顺铂耐药的A2780/Cis卵巢癌细胞进行实验。使用比较分子场分析和全息量化结构-活性关系探讨了35种萘基类黄酮的结构特性与它们的克隆形成能力之间的关系。结果表明,识别出几种可以增强细胞生长抑制活性的结构特征,进一步设计并合成了满足这些条件的化合物5-(2,3-二甲氧基苯基)-3-(1-羟基萘-2-基)-N-苯基-4,5-二氢-1H-吡唑-1-碳硫酰胺。该新型化合物的半最大细胞生长抑制浓度低于本文测试的35种类黄酮衍生物。因此,本报告中观察到的结构特征可用于设计和开发有效的化疗药物以治疗卵巢癌细胞。
