polymerases. Although the incorporation efficiency is not very high, it demonstrates that some of these dipeptides can be accommodated in the active site of polymerases and function as leavinggroups in the enzymatic synthesis of DNA.
alkylation of Schiff base activated amino acids and small peptides via a Pd/Cu dual catalysis. A range of noncoded α,α-dialkyl α-aminoacids were easily synthesized in high yields and with excellent enantioselectivities (up to >99% ee). Furthermore, a direct and highly stereoselective synthesis of small peptides with enantiopure α-alkyl or α,α-dialkyl α-aminoacids residues incorporated at specific sites

The present invention is referred to tripeptides having the following general formula: X-Gly-Y where X=L-Arg or D-Arg and Y=L-Asp or D-Asp. These tripeptides, endowed with both immunostimulant and antimetastatic properties, are active not only after parenteral administration, but also after oral treatment. The invention is also related to the procedure for the preparation of said compounds.

3-amino-closo-carborane and a glutaric acid residue as a linker fragment. The resulting carboranyl derivatives of the protected RGD peptide are of interest as starting compounds in the synthesis of unprotected or selectively protected peptides, as well as building blocks for preparation of boron-containing derivatives of the RGD peptide of a more complex structure.
