The results demonstrate that ACM-A is capable of intercalating between the base pairs of DNA double helix, the π-π electronic overlapping between π-electron of ACM-A and DNA stabilizes the ACM-DNA adduct, and through electrostatic interaction, the trisaccharide interacts with the minor groove of DNA owing to C(3') amino group.

实验结果表明，ACM-A主要以其蒽环平面嵌入DNA双螺旋碱基对之间，发生-等电子间相互共轭，同时药物糖基上C3'位的-N(CH3)2基团带正电荷，易与带负电荷的磷酸骨架产生静电吸引，从而发生沟槽作用，嵌入DNA的小沟区，这是二者之间的主要结合模式。并且，DNA与ACM-A药物原型的亲和力要强于还原后的药物代谢产物。
