dioncoquinone B (6) and the isolation of its new, even higher-oxygenated analogs, dioncoquinones C (7), D (8), and E (9), from cell cultures of Triphyophyllum peltatum. In addition, several derivatives of these compounds were synthesized, including dioncoquinone C (7), and a small library of naphthoquinones was created. Furthermore, the first structure-activity relationship (SAR) study on this class of compounds
由于它们有希望的抗肿瘤和抗感染活性,二苯并二氢醌属于感兴趣的天然萘醌产品家族。特别地,已显示二oncoquinones A(5)和B(6)对利什曼原虫和多发性骨髓瘤细胞具有高活性,而对正常血细胞没有任何明显的毒性。它们对多发性骨髓瘤细胞系的有效浓度类似于美法仑(melphalan),一种用于B细胞淋巴瘤和多发性骨髓瘤的标准疗法的众所周知的DNA烷基化剂。我们报道了高度氧化的抗肿瘤剂dioncoquinone B(6)的第一个全合成及其新的甚至更高氧化的类似物dioncoquinones C(6)的分离。7),D(8)和E(9),来自pel粉的细胞培养。此外,还合成了这些化合物的几种衍生物,包括二oncoquinone C(7),并创建了一个小的萘醌文库。此外,针对此类化合物进行了首次结构-活性关系(SAR)研究,结果表明,C- 3,C- 5和C- 6的三个羟基中的每一个均需要改善的抗肿瘤作用活性和降低的细胞毒性。
