for new anticancer agents we designed and synthesized batracylin derivatives with linking synthetic amino acid side chains of different lengths and adenosine. Unexpectedly, we have found that in water and the culture media adenosine–amino acid–BAT conjugates form supramolecular structures and this prevents these compounds from entering cells. Consequently, these compounds exerted no biological activity
在寻找新的抗癌剂时,我们设计并合成了具有不同长度的合成氨基酸侧链和腺苷的batracylin衍生物。出乎意料的是,我们发现在水和培养基中,腺苷-氨基酸-BAT共轭物形成超分子结构,这阻止了这些化合物进入细胞。因此,当针对两种人类细胞系,肺腺癌(A549)和人类白血病(HL-60)进行测试时,这些化合物没有生物学活性。相反,与BAT相比,几种氨基酸-BAT前体显示出高达25倍的增强的细胞毒活性,并且这些化合物强烈干扰DNA拓扑异构酶II的活性及其细胞功能。尤其是,
