中文摘要：
以间苯二酚和对苯二酚为起始原料,经过傅克酰化、Baker-Venkataraman重排、关环三步反应分别得到5个7-羟基黄酮和5个6-羟基黄酮类化合物.试验结果发现,这些化合物溶解性能不好,生物活性不高,因此,对这些化合物又经过苯甲酰化并将7-羟基黄酮与1-氯-3-溴丙烷首先发生亲核取代反应,然后和诺氟沙星在丙酮中反应生成化合物13,总共得到了5个结构新颖的黄酮和4个未见文献报道的β-丙二酮类化合物.通过四甲基偶氮唑盐(MTT)法对19个化合物的抑制人宫颈癌细胞Hela活性进行了体外评价,结果表明:化合物13的半数抑制浓度IC50为19.4μmol/L,具有深入研究的价值.
英文摘要：
Five 7-hydroxylflavones and five 6-hydroxylflavones have been synthesized with resorcinol and paradioxybenzene as starting materials in three steps by an improved Baker-Venkatarama rearrangement reaction. Experimental results showed that the ten compounds have poor solubility in methanol and chloroform solvent and low biological activity. Therefore, some of these compounds are further derivatived and five new compounds were successfully synthesized. The nineteen compounds, including four new β-propenediones 4b, 4c, 4d and 4e, were evaluated for antitumor activities against hela human cervical carcinoma cell lines by methyl thiazolyl tetrazolium (MTT) method. The preliminary biological activity tests showed that compound 13 exhibited potentially high activity against hela human cervical carcinoma cell lines with IC50 value of 19.4μmol/L.
