神经酰胺是神经鞘脂代谢和信号通路的中枢介质,调节许多基本的细胞反应。它被称为“肿瘤抑制脂质”,因为它有力地增强了驱动细胞凋亡、细胞周期阻滞和自噬反应的信号事件。在典型的癌细胞中,神经酰胺代谢酶的过度表达或神经酰胺生成酶的下调通常会抑制神经酰胺水平和信号传导。然而,化疗药物和放疗增加细胞内神经酰胺水平,而外源性用短链神经酰胺治疗癌细胞导致抗癌作用。目前所有的证据都表明,神经酰胺水平的上调是一个很有前景的抗癌靶点。在这篇综述中,我们展示了一系列抗癌神经酰胺类似物作为下游受体激动剂和神经酰胺代谢酶抑制剂。
Ceramide serves as a central mediator in sphingolipid metabolism and signaling pathways, regulating many fundamental cellular responses. It is referred to as a “tumor suppressor lipid”, since it powerfully potentiates signaling events which drive apoptosis, cell cycle arrest, and autophagic responses. In the typical cancer cell, ceramide levels and signaling are usually suppressed by over-expression of ceramide-metabolizing enzymes or down-regulation of ceramide-generating enzymes. However, chemotherapeutic drugs as well as radiotherapy increase intracellular ceramide levels while exogenously treating cancer cells with short-chain ceramides leads to anti-cancer effects. All evidence currently points to the fact that the up-regulation of ceramide level is a promising anti-cancer target. In this review, we exhibited a full scroll of anti-cancer ceramide analogs as down-stream receptor agonists and ceramide metabolizing enzyme inhibitors.
