Psychosine (Synonyms: Galactosylsphingosine)

Psychosine (Galactosylsphingosine) 是半乳糖脑苷脂酶 (GALC) 酶的底物,是 Krabbe 病的潜在生物标志物。Psychosine 是一种高度细胞毒性的脂质,能够在多种细胞类型中诱导细胞死亡,且有部分是通过细胞凋亡 (apoptosis) 导致的细胞死亡。Psychosine 还是一种 PKC 抑制剂。

生物活性

Psychosine (Galactosylsphingosine), a substrate of the galactocerebrosidase (GALC) enzyme, is a potential biomarker for Krabbe disease[1]. Psychosine is a highly cytotoxic lipid, capable of inducing cell death in a wide variety of cell types including, most relevantly to globoid cell leukodystrophy (GLD), oligodendrocytes. Psychosine causes cell death at least in part via apoptosis. Psychosine also is an inhibitor of PKC[1].

PKC

 

体外研究
(In Vitro)

Psychosine, is a substrate of the GALC enzyme that shows promise to aid in the diagnosis and follow-up of at-risk infants identified through newborn screening (NBS)[1]. Psychosine induces pleiotropic effects, including dysfunctions in several cellular pathways[2].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
