title: Oral administration of semisynthetic sphingolipids promotes recovery of striatal dopamine concentrations in a murine model of parkinsonism.
abstract: The neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administered to young C57/B16J black mice caused a striatal dopamine depletion that could be at least partially reversed by chronic intraperitoneal administration of GM1 ganglioside. The present study shows that the semisynthetic sphingolipids LIGA 4 (II3Neu-5-AcGgOse4-2-d-erythro-1,3-dihydroxy-2-acetamide-4-t rans-octadacene) and LIGA 20 (II3Neu-5-AcGgOse4-2-d-erythro-1,3-dihydroxy-2-chloro-acetam ide-4- trans-octadacene) are also effective in at least partially reversing MPTP-induced striatal dopamine depletions in mice after oral administration. These results suggest that semisynthetic ganglioside derivatives may be superior to the parent GM1 ganglioside for human clinical use.
