  羟基肉桂酸衍生物的抗氧化与细胞毒性特性——酚类研究的新范式

  摘要：

  合成了三羟基肉桂衍生物并评估了它们的抗氧化和细胞毒活性。当脂质体用作目标系统时，酯衍生物表现出更高的自由基清除活性，这一事实可能与其亲脂性和构象偏好有关。发现这些化合物对人子宫颈腺癌细胞系 (HeLa) 显示出显着的生长抑制和细胞毒性作用。目前获得的三羟基肉桂酸衍生物的分配系数与其结构特征和抗氧化/细胞毒活性密切相关。预计细胞毒性和抗氧化活性之间存在正构-活性-特性关系，这与物理化学和构象特性具有内在相关性，作为一项值得注意的研究，必须对酚醛系统进行。由于损伤事件经常与氧化应激相关，单一化合物中两种特性的普遍存在可能有益于预防或治疗目的。

  trihydroxycinnamic derivatives correlate well both with their structural characteristics and with their antioxidant/cytotoxic activities. A positive structure‐activity‐property relationship between cytotoxic and antioxidant activities, which is intrinsically related with physico‐chemical and conformational properties, is anticipated, as a noteworthy study that must be done for phenolic systems.

  Phenolic acids are ubiquitous antioxidants accounting for approximately one third of the phenolic compounds in our diet. Their importance was supported by epidemiological studies that suggest an inverse relationship between dietary intake of phenolic antioxidants and the occurrence of diseases, such as cancer and neurodegenerative disorders. However, until now, most of natural antioxidants have limited therapeutic success a fact that could be related with their limited distribution throughout the body and with the inherent difficulties to attain the target sites.The development of phenolic antioxidants based on a hybrid concept and structurally based on natural hydroxybenzoic (gallic acid) and hydroxycinnamic (caffeic acid) scaffolds seems to be a suitable solution to surpass the mentioned drawbacks. Galloyl cinnamic hybrids were synthesized and their antioxidant activity as well as partition coefficients and redox potentials evaluated. The structure property activity relationship (SPAR) study revealed the existence of a correlation between the redox potentials and antioxidant activity. The galloyl cinnamic acid hybrid stands out as the best antioxidant supplementing the effect of a blend of gallic acid plus caffeic acid endorsing the hypothesis that the whole is greater than the sum of the parts. In addition, some hybrid compounds possess an appropriate lipophilicity allowing their application as chain-breaking antioxidant in biomembranes or other type of lipidic systems. Their predicted ADME properties are also in accordance with the general requirements for drug-like compounds. Accordingly, these phenolic hybrids can be seen as potential antioxidants for tackling the oxidative status linked to the neurodegenerative, inflammatory or cancer processes.
