P-ManNAc

Product information

• Function

  P-ManNAc is a control compound for labeling/inhibition experiments utilizing acetylated mannosamine derivatives P-ManNAz, P-ManDAz, P-ManNPent, P-ManNPoc.¹

• Mode of action

  P-ManNAc is taken up by cells via passive diffusion because this compound contains O-acetyl (OAc) groups. These groups make the molecule more lipophilic so that it can passively diffuse over mammalian cell membranes. Inside cells, these O-acetyl groups are removed via non-specific esterase releasing N-acetylmannosamine and acetic acid. It is possible that at high concentrations, the released acetic acid or the partially acetylated intermediates are toxic. In addition, at high concentrations, non-specific reactions of acetylated precursors and cysteine residues have been observed.² At low µM concentrations, these effects may be negligible but it is advisable to use a control compounds such as P-ManNAc. Finally, P-ManNAc may be used to boost intracellular ManNAc levels. It has for example been shown that P-Neu5Ac can be used to boost intracellular neuraminic acid levels.³

• Applications

  Control compound for labeling/inhibition experiments utilizing acetylated mannosamine derivatives. P-ManNAz, P-ManDAz, P-ManNPent, P-ManNPoc

• Handling

  P-ManNAc is soluble in a mixture of DMSO and PBS and is added to cell culture from a stock solution.
