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.
Ibiglustat (Venglustat) succinate is an orally active, brain-penetrant inhibitor of glucosylceramide synthase (GCS). It is utilized in the investigation of Gaucher disease type 3, Parkinson's disease associated with GBA mutations, Fabry disease, GM2 gangliosidosis, and autosomal dominant polycystic kidney disease.
