General description

Desmosterol constitutes 1% of brain sterol and is catabolized to cholesterol by the enzyme 3-hydroxysterol 24-reductase (DHCR24). It is an intermediate in the Bloch branch of the cholesterol biosynthesis pathway. Desmosterol-d6 is a deuterated form of desmosterol.

Application

Desmosterol-d6 has been used:
  • as a deuterated standard in liquid chromatography multiple reaction monitoring (LC-MRM)
  • as a deuterated standard in high-performance liquid chromatography/electrospray ionization tandem mass spectrometry (HPLC-ESI-MS)
  • for spiking brain tissue homogenate from Alzheimer′s disease (AD) for liquid chromatography -mass spectrometry (LC-MS) analysis

Biochem/physiol Actions

Desmosterol low levels in the hippocampus directly impacts progenitor cell differentiation into neurons. Desmosterol-d6 is used as a substitute to desmosterol in hepatitis C virus (HCV) based viral assays to rescue replication. Desmosterol being a C27 sterol intermediate is implicated in the Alzheimer′s disease (AD) pathogenesis.

Hepatitis C virus (HCV) increases intracellular desmosterol without affecting the steady-state abundance of other sterols, and the antiviral activity of inhibitors of desmosterol synthesis is suppressed by the addition of exogenous desmosterol. These observations suggest a model in which desmosterol
