Immobilized heterologous Rhizopus Oryzae lipase as an efficient catalyst in the acetylation of cortexolone
(Wiley VCH Verlag, 2012-08)
The enzymatic preparation of a monoacetyl derivative of the corticosteroid cortexolone, through a transesterification reaction, is described. The heterologous Rhizopus oryzae lipase, immobilized on three different supports, ...
Ca(2+)-mediated thiolysis of peptide-resin linkage as an option for preparing protected peptide thioesters
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A mild new procedure for preparing protected peptide thioesters, based oil Ca(2+)-assisted thiolysis of peptide-Kaiser oxime resin (KOR) linkage, is described. Ac-Ile-Ser(Bzl)-Asp(OcHx)-SR (Ac: acetyl; Bzl: benzyl; cHx: ...
