Latest Patents

One of Cristau's key patents is titled "Diketopiperazine forming dipeptidyl linker." This invention relates to a method for homogeneous solution phase peptide synthesis (HSPPS) of a N-terminal peptide fragment PEP-N and a C-terminal peptide fragment C-PEP. The C-PEP carries a specific diketopiperazine (DKP) that includes a C-terminal protecting group, which contains a handle group (HG) connected to the C-terminus of the peptide fragment. This specific DKP can be selectively cleaved from the peptide, allowing for more streamlined processes in convergent peptide synthesis by combining HSPPS and solid phase peptide synthesis (SPPS). The invention also details a method for preparing the specifically protected fragment C-PEP by SPPS, utilizing a linker that forms the DKP group when the peptide fragment is cleaved from the supporting resin.
