4-acetamido-3,3,5,5-[2H4]-2,2,6,6-tetra([2H3]methyl)piperidin-1-yloxyl 0.33-hydrate.

The asymmetric unit of the title compound, C11H5D16N2O(2).0.33H2O, is formed by three crystallographically independent piperidin-1-yloxyl molecules and a molecule of water.

Binding of D-mannose to poly(2-hydroxyethyl methacrylate) hydrogels by azo coupling.

Crosslinked hydrogels based on poly(2-hydroxyethyl methacrylate) poly(HEMA) were prepared and modified with tyramine [4-(2-aminoethyl)phenol] to enable azo coupling with mannosyl derivatives, copolymerization of HEMA with polymerizable activated esters and surface modification reaction with 4-nitrophenyl chlorocarbonate for activation of the hydrogels were used.

Mannosides as crucial part of bioactive supports for cultivation of human epidermal keratinocytes without feeder cells.

Large-scale production of keratinocytes by cell culture is of interest for medical applications. Long-term cultivation of epidermal cells is presently possible with feeder cells, i.e.
