An attempt was made to obtain more potent antitumor compounds by chemically modifying asterriquinones. Amino-and aziridinyl-asterriquinone were newly synthesized, but showed no activity. However, dimethylallylation of asterriquinone Cl, which had no effect in vivo, yielded an active compound, with a change in pKa value from 5.0 to 7.2. This suggests that other active compounds may be obtained by the chemical modification of asterriquinones with various other functional groups.
人们试图通过化学修饰阿斯特里醌来获得更有效的抗肿瘤化合物。新合成的氨基和氮丙啶基紫檀醌没有显示出活性。然而,对在体内无作用的紫檀醌 Cl 进行二甲基烯丙基化后,得到了一种活性化合物,其 pKa 值从 5.0 变为 7.2。这表明,通过用其他各种官能团对星状醌进行化学修饰,可能会得到其他活性化合物。
