C8 Galactosylceramide is a synthetic C8 short-chain derivative of known membrane microdomain-forming sphingolipids. It increases the amount delivered and toxicity of doxorubicin in cancerous but not non-cancerous cells when incorporated into the nanoliposomal membrane of nanoliposomal-doxorubicin. C8 Galactosylceramide induces proliferation and cytokine production by splenocytes in vitro at concentrations ranging from 100-1,000 ng ml but has no effect on natural killer T cell production in vivo. It also activates NF-κB production in C6 glioma cells when used at a concentration of 10 μM.

C2 Adamantanyl Galactosylceramide (d18:1 2:0) (AdaGalCer) is a bioactive sphingolipid. It reduces globotriaosylceramide 3 synthesis from exogenous lactosylceramide in microsomes. AdaGalCer stimulates recombinant glucocerebrosidase activity in a pH-dependent manner. It activates glucocerebrosidase to decrease glucosylceramide accumulation in fibroblasts and lymphoblasts isolated from patients with Gaucher and Fabry disease, respectively.

C16 3'-sulfo Galactosylceramide (d18:1 16:0)是硫酸盐类糖脂的一种。C16 3'-sulfo Galactosylceramide (d18:1 16:0)是在猪脑和血浆中发现的一种比较丰富的硫化物，在小鼠的整个发育过程中会有所减少。C16 3'-sulfo Galactosylceramide (d18:1 16:0)在体外可抑制视网膜神经节细胞生长。C16 3'-sulfo Galactosylceramide (d18:1 16:0)已被用作量化大鼠小脑和多发性硬化症患者分离的白质中的硫化物的参照物。

C18 3'-sulfo Galactosylceramide is a member of the sulfatide class of glycolipids. Levels of short-chain sulfatides, including C18 3'-sulfo galactosylceramide, decrease with age in mice and humans. It is increased in brain from mice with an arylsulfatase A deficiency (ASA-KO), particularly in lipid raft fractions. Plasma levels of C18 3'-sulfo galactosylceramide positively correlate with disability progression in patients with relapsing-remitting multiple sclerosis using the Expanded Disability Status Scale. It is also increased in plasma from patients with metachromatic leukodystrophy (MLD).

Tetracosanoyl-sulfatide is an endogenous sulfated glycolipid, which are also known as sulfatides . Tetracosanoyl-sulfatide is the major sulfatide in mature myelin in the central and peripheral nervous systems. Levels of Tetracosanoyl-sulfatide are elevated in plasma derived from patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency, leading to sulfatide accumulation. Unlike C24:1 3'-sulfo galactosylceramide, it does not induce an immune response in mouse splenocytes in vitro.

α-Galactosylceramide analog 8 (α-GalCer analog 8) is a triazole derivative of α-galactosylceramide. [1] It increases IL-2 secretion by DN32.D3 NKT hybridoma cells when co-cultured with CD1d-transfected RBL cells pre-loaded with α-GalCer analog 8 at a concentration of 32 ng ml. α-GalCer analog 8 (32 ng ml) induces IL-4 secretion to a greater extent than the synthetic α-GalCer KRN 7000 in mouse splenocytes in vitro and in mouse serum following administration of a 1 µg per animal dose, indicating a Th2 response.

KBC-007 is a synthetic branched chain-containing analog of α-galactosylceramide (α-GalCer). It induces IL-4 and IFN-γ secretion by mouse splenocytes when used at a concentration of 0.5 ng/ml and IL-2 secretion by DN32.D3 NKT hybridoma cells co-cultured with CD1d-transfected RBL cells pre-loaded with KBC-007 at a concentration of 8 ng/ml. KBC-007 (1 μg per animal) increases levels of IL-4, but not IFN-γ, to a similar degree as α-GalCer in mouse serum.
