xenograft models in vivo. At present there is a deficiency of information on the structural requirements for the activity of CTU. Our initial study suggested that electron withdrawing groups were required on the aryl ring, and in this study we further evaluated the influence of the electronicproperties of aromatic substitution on the capacity of CTU analogues to decrease MDA-MB-231 breast cancer cell viability

protonophores and mitochondrial uncouplers that utilise a urea-based synthetic anion transport moiety to carry out the protonophoric cycle. Herein we show that replacement of the urea group with carbamate, a functional group not previously reported to possess anion transport activity, produces analogues that retain the activity of their urea counterparts. Thus, the aryl-carbamate substituted fatty
芳基脲取代的脂肪酸是质子载体和线粒体解偶联剂,它们利用基于尿素的合成阴离子转运部分来进行质子循环。在这里,我们表明用氨基甲酸酯(一种以前没有报道过具有阴离子转运活性的官能团)取代尿素基团会产生保留其尿素对应物活性的类似物。因此,芳基氨基甲酸酯取代的脂肪酸解偶联氧化磷酸化并通过破坏线粒体质子梯度来抑制 ATP 的产生。质子传输通过去质子化的芳基氨基甲酸酯自组装成膜可渗透的二聚体,通过羧酸基团与氨基甲酸酯部分的分子间结合形成。这些结果突出了氨基甲酸酯官能团的阴离子传输能力。
