C2 Adamantanyl galactosylceramide (AdaGalCer) (d18:1/2:0) is a bioactive sphingolipid. C2 Adamantanyl galactosylceramide (d18:1/2:0) stimulates glucocerebrosidase activity in vitro. C2 Adamantanyl galactosylceramide (d18:1/2:0) inhibits microsomal LacCer and Gb3 synthase, and inhibits cell sulfatide synthesis. C2 Adamantanyl galactosylceramide (d18:1/2:0) reduces glucosylceramide (GlcCer) levels in normal and lysosomal storage disease (LSD) cells. C2 Adamantanyl galactosylceramide (d18:1/2:0) acts as a substrate for A4GALT and is able to lower Gb3 levels with an IC50 concentration of 40 µM in fabry disease cells[1][2].
