权利人:CHEN LIN; HAN YEUN-KWEI; ROBERTS CHRISTOPHER R
摘要:Methods for the synthesis of cyclic peptides are provided, as well as novel dipeptide compounds. The methods include the solid phase synthesis of a dipeptide, which is the coupled to a second peptide in a solid phase reaction. The peptide is then cyclized following the coupling reaction. The methods and dipeptides are particularly useful for the synthesis of MC-4 receptor agonist peptides.

摘要:Silicatein is an enzyme of silicate-forming organisms used for the synthesis of their silicate scaffold. The present invention relates to the use of highly-expressed and highly active recombinant silicatein, silicatein isolated from natural sources after gene induction as well as silicatein-fusion proteins for the synthesis of amorphous silicon dioxide (silicic acids and silicates), siloxanes as well as modification of these compounds and their technical use.
