C8 Ceramide, a cell-permeable analog, is analog to naturally occur ceramides.

Sphinganine (d20:0) is a natural isomer of dihydro-D-erythro-sphinganine (sphinganine (d18:0); that is a precursor of ceramide and sphingosine as well as a substrate for sphingosine kinases, which generate sphingosine-1-phosphate (d18:1) . In S. cerevisiae, the amount of sphinganine (d20:0) increases 10.8-fold in response to heat stress, indicating it is involved in heat stress adaptation. Sphinganine levels increase significantly in response to certain mycotoxins, including fumonisins as well as in some cancers. Sphinganine can block protein kinase C activation in some cases but not others.

C8 Dihydroceramide acts as a negative control for C8 Ceramide, a cell-permeable analog of natural ceramides. C8 Ceramide, also known as N-Octanoyl-D-erythro-sphingosine, exhibits potent chemotherapeutic properties and anti-proliferation effects. Additionally, it stimulates dendritic cells to enhance T cell responses during viral infections. In vitro studies have also shown that C8 Ceramide induces a slight activation of protein kinase (PKC) [4].

Sphinganine 1-phosphate (鞘氨醇-1-磷酸）是sphingolipid代谢途径中的一个中间产物，结构上和sphingosine相似。D-erythro-Dihydrosphingosine 1-phosphate在小鼠中通过激活S1P1受体对肾脏和肝脏具有保护作用。在智人（Homo sapiens）中作为S1P4的激动剂，并且可能激活GPR63（G蛋白偶联受体），主要用于研究Fabry病，Gaucher病，Krabbe疾病和脑白质营养不良（Leukodystrophy）。

C18 Ceramide-1-phosphate (d18:1 18:0) 是一种在鼠皮肤中发现的长链ceramide-1-phosphate。它能在0.5至5 µM的浓度范围内促进分离的小鼠骨髓来源的多能间充质细胞和人脐静脉内皮细胞（HUVECs）的迁移。与胰腺癌干细胞相比，CFPAC-1胰管腺癌细胞中C18 Ceramide-1-phosphate (d18:1 18:0)的水平有所增加。在Langendorff分离的灌流小鼠心脏的离体缺血模型中，心肌中C18 ceramide-1-phosphate (d18:1 18:0)的水平有所增加。

C2 Dihydro Ceramide (d18:0 2:0) (C2 Dihydroceramide) 是短链的神经酰胺，是神经酰胺合成前体，可刺激 ABCA1 介导的胆固醇外流。

Sphingosine (d18:1), an amino alcohol, is chiefly recognized for its 18-carbon unsaturated hydrocarbon chain. Nevertheless, in mammalian tissues, both sphingosine and its variant, dihydrosphingosine, feature hydrocarbon chains ranging from 12 to 26 carbons. Sphingosine (d15:1) represents a naturally rare variant, serving as an internal standard for chromatographic or spectrometric analyses of sphingoid compounds.

Sphingosine (d16:1), an unconventional sphingolipid, is synthesized through enzymatic reactions starting with the condensation of myristoyl-CoA and serine by serine palmitoyltransferase long-chain base subunit 3 (SPTLC3), which shows a preference for myristoyl-CoA. This compound is found in minute quantities in its free form in human plasma and as a component of various plasma sphingolipids, such as sphingosine-1-phosphate, ceramides, sphingomyelins, and in brain cerebrosides, albeit at lower concentrations than the more common d18:1 sphingoid base. Sphingosine (d16:1) acts as an inhibitor of PKC in mixed micelle assays and diminishes superoxide production triggered by phorbol 12-myristate 13-acetate in isolated human neutrophils, as well as inhibiting the growth of CHO cells with IC50 values of 1 and 3.2 µM, respectively. Additionally, the concentration of sphingolipids containing sphingosine (d16:1) in the plasma is linked to the dietary consumption of saturated fatty acids and protein among ethnic Chinese populations.
