Ceramides play a crucial role in the barrier function of the skin as well as in transmembrane signaling. In this study long aliphatic chain tartaric acid diamides able to replace ceramides in an in vitro model of the stratum corneum lipid matrix due to their similar physico-chemical properties were synthesized from diacetoxysuccinic anhydride in four steps. Their pro-apoptotic effect on fibroblast cells was also investigated.
神经酰胺在皮肤的屏障功能和跨膜信号传递中发挥着至关重要的作用。本研究以
二乙酰氧基
丁二酸酐为原料,通过四个步骤合成了长脂肪链
酒石酸二元胺,由于它们具有相似的物理
化学性质,因此能够在角质层脂质基质的体外模型中替代神经酰胺。此外,还研究了它们对成纤维细胞的促凋亡作用。
