  Synthesis and anticancer effect of chrysin derivatives

  摘要：

  A series of chrysin derivatives, prepared by alkylation, halogenation, nitration, methylation, acetylation and trifluoromethylation, were tested in vitro against human gastric adenocarcinoma cell line (SGC-7901) and colorectal adenocarcinoma (HT-29) cells. Among these derivatives of chrysin, 5,7-dimethoxy-8-iodochrysin 3 and 8-bromo-5-hydroxy-7-methoxychrysin 11 have the strongest activities against SGC-7901 and HT-29 cells, respectively. 5,7-Dihydroxy-8-nitrochrysin 12 were found to have strong activities against both SGC-7901 and HT-29 cells.

  carbonarius cultured in a conducive liquid medium. The best control effect on OTA biosynthesis was achieved using NEG and DHF. In fungal cultures treated with these compounds at 5, 25, and 50 μg/mL, OTA biosynthesis significantly decreased throughout the 8-day experiment. NEG and DHF appear to have an inhibiting effect also on the activity of LOX, whereas MOS, which did not significantly inhibit OTA production

  赭曲霉毒素 A (OTA) 是一种严重影响人类健康的霉菌毒素。在地中海国家，黑曲霉群，尤其是炭黑曲霉，造成最高的 OTA 污染。在这里，我们描述了三种多酚类黄酮的合成：5-羟基-6,7-二甲氧基-黄酮 (MOS)、5,6-二羟基-7-甲氧基-黄酮 (NEG) 和 5,6-二羟基-黄酮 (DHF) ，以及它们对在有益液体培养基中培养的炭黑炭疽菌中 OTA 生物合成和脂氧合酶 (LOX) 活性的预防作用。NEG和DHF对OTA生物合成的控制效果最好。在用 5、25 和 50 μg/mL 的这些化合物处理的真菌培养物中，OTA 生物合成在整个 8 天实验中显着降低。NEG 和 DHF 似乎也对 LOX 的活性有抑制作用，而 MOS，没有显着抑制 OTA 产生，对 LOX 活性没有影响。分子中儿茶酚位置游离羟基的存在似乎是显着抑制 OTA 生物合成的决定因素。然而，NEG 中 C-7 中甲氧基的存
