(Z)-stilbenoid combretastatin A4, have been considered as promising lead compounds for the development of anticancer drugs. The antitumour properties of stilbenoids are known to be modulated by cytochrome P450 enzymes CYP1A1 and CYP1B1, which contribute to extrahepatic phase I xenobiotic and drug metabolism. Thirty-four methyl ether analogues of resveratrol were synthesised, and their anticancer properties were
天然存在的二苯乙烯类化合物,如 (E)-二苯乙烯类白藜芦醇和 (Z)-二苯乙烯类化合物 combretastatin A4,已被认为是开发抗癌药物的有前途的先导化合物。已知二苯乙烯类化合物的抗肿瘤特性受细胞色素 P450 酶 CYP1A1 和 CYP1B1 的调节,这有助于肝外 I 期外源性物质和药物代谢。合成白藜芦醇的 34 种甲基醚类似物,并在一组人乳腺细胞系上使用 MTT 细胞增殖测定评估其抗癌特性。表达 CYP1 的乳腺肿瘤细胞系比不具有 CYP1 活性的细胞系受白藜芦醇类似物的影响明显更强。使用分离的 CYP1 酶的代谢研究提供了进一步的证据,证明 (E)-二苯乙烯类化合物可以成为这些酶的底物。通过与合成标准品和 LC-MS 共洗脱研究进行比较来确认代谢产物的结构。最有前途的二苯乙烯类化合物是 (E)-4,3′,4′,5′-四甲氧基二苯乙烯 (DMU212)。该化合物本身显示出低至中度的细胞毒性,但在
