The synthesis of two new sulfated xanthones and two O-substituted benzophenones was carried out to evaluate for their inhibitory effect on growth of human tumor cell lines. The sulfation of 3,6-(2) and 3,4-dihydroxyxanthone (3) was accomplished using sulfur trioxide-pyridine to give, respectively, xanthone-3,6-O,O-bis(sulfate) (4) and xanthone- 3,4-O,O-bis(sulfate) (5). Treatment of 2,2,4,4-tetrahydroxybenzophenone (6) with acetic acid and prenyl bromide furnished 2,2,4,4- tetraacetoxybenzophenone (7) and (5-hydroxy-2,2-dimethylchroman-6-yl)(2-hydroxy-4-(tertpentyloxy) phenyl)methanone (8), respectively. Compounds 2-8 were tested for their effect on the in vitro growth of four representative human tumor cell lines: MCF-7 ER(+) (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer), SF-268 (glioma), and A375-C5 (melanoma). Compounds 2 and 7-8 showed an inhibitory activity in the μM range.`
对两种新的硫酸化氧杂蒽酮和两种O-取代二苯甲酮进行了合成,以评估它们对人类肿瘤细胞系生长的抑制作用。使用三氧化硫-吡啶对3,6-(2)和3,4-二羟基氧杂蒽酮(3)进行硫酸化,分别得到氧杂蒽酮-3,6-O,O-双(硫酸盐)(4)和氧杂蒽酮-3,4-O,O-双(硫酸盐)(5)。用乙酸和异戊烯基溴化物处理2,2,4,4-四羟基二苯甲酮(6),分别得到2,2,4,4-四乙酰氧基二苯甲酮(7)和(5-羟基-2,2-二甲基苯并二氢吡喃-6-基)(2-羟基-4-(叔戊基氧基)苯基)甲酮(8)。对化合物2-8在体外对四种典型人类肿瘤细胞系生长的抑制作用进行了测试:MCF-7 ER(+)(乳腺癌腺癌)、NCI-H460(非小细胞肺癌)、SF-268(胶质瘤)和A375-C5(黑色素瘤)。化合物2和
