3-O-acetyl-sphingosine-series myelin glycolipids: characterization of novel 3-O-acetyl-sphingosine galactosylceramide.
Several glycosphingolipids, less polar than galactosylceramide (GalCer), have been purified from rat brain and designated as fast migrating cerebrosides (FMCs). They co-appear with GalCer during myelinogenesis, reach a peak concentration at postnatal day 25-30 and are derivatives of GalCer. Extensive structural analysis of the partially methylated alditol acetates, mass-spectrometry, and (1)H- ...
متن کاملInvariant Natural Killer T-cell anergy to endogenous myelin acetyl-glycolipids in multiple sclerosis.
To extend our studies on glycolipid-reactive invariant Natural Killer T-cell (iNKT-cell) function in multiple sclerosis (MS), we investigated the stimulatory activities of two myelin-derived glycolipids that are poly-acetylated derivatives of β-galactosylceramide designated as fast-migrating cerebrosides (FMC) by thin-layer chromatography. In healthy subjects, FMC stimulation of peripheral bloo...
متن کامل3′-O-Acetyl-2′-deoxyuridine
In the two independent but very similar mol-ecules of the title compound, C(11)H(14)N(2)O(6), both nucleobase fragments are nearly planar (both within 0.01 Å) while the furan-ose rings exhibit (2)E-endo envelope conformations. In the crystal, the two 3'-O-acetyl-2'-de-oxy-uridine mol-ecules form a pseudosymmetric dimer of two bases connected via two nearly identical resonance-assisted N-H⋯O hyd...
متن کاملNovel myelin penta- and hexa-acetyl-galactosyl-ceramides: structural characterization and immunoreactivity in cerebrospinal fluid.
Fast migrating cerebrosides (FMC) are derivatives of galactosylceramide (GalCer). The structures of the most hydrophobic FMC-5, FMC-6, and FMC-7 were determined by electrospray ionization linear ion-trap mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy complementing previous NMR spectroscopy and gas chromatography-mass spectrometry to be 3-O-acetyl-sphingosine-GalCer der...
متن کامل3-Acetyl-1-phenylthiourea
In the crystal structure of title compound, C(9)H(10)N(2)OS, there are two symmetry-independent mol-ecules, each having an intra-molecular N-H⋯O hydrogen bond generating an S(6) ring motif. The benzene rings and the virtually planar acetyl-thoiurea fragments [r.m.s. deviations = 0.0045 and 0.0341 Å] are oriented at dihedral angles of 50.71 (6) and 62.79 (6)° in the two mol-ecules. In the crysta...
