A mild and quantitative procedure for the removal of nucleoside alkoxycarbonyl groups using pig liver esterase or Candida antarctica B lipase
A set of eight mono-, di-, tri- and tetraalkoxycarbonylated nucleosides was tested in order to assess their enzymatic hydrolysis. All the alkoxycarbonyl groups of the assayed substrates, from both carbonate and carbamate functions, were quantitatively hydrolysed using pig liver esterase (PLE) at pH...
