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。

The invention relates to new derivatives of 5-aminolevulinic acid (5-ALA) and their use as photosensitizing agents. In particular, it relates to compounds of general formula I and their pharmaceutically acceptable salts, to methods for preparing such compounds and their medical and cosmetic use, for example in methods of photodynamic therapy and diagnosis: wherein R1 represents a hydrogen atom or an optionally substituted alkyl or cycloalkyl group; R2, each of which may be the same or different, represents a hydrogen atom or an optionally substituted alkyl group; and X is a linking group.
