(R)-N(Me)-Leu. Deprotection of the amino and carboxyl terminii of this linearprecursor followed by macrocyclization gave a protected derivative of didemnin A. The second route involved synthesis of the Boc-protected didemnin macrocycle from a linear hexadepsipeptide lacking (R)-N(Me)-Leu. Removal of the Boc group from the macrocycle followed by its coupling with Boc-(R)-N(Me)-Leu-OH then gave Boc-didemnin A

Thymosin β4 fragment 16-38, H-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-OH, was synthesized by a solution method, by assembling five peptide fragments followed by deprotection with 1 M trifluoromethanesulfonic acid-thioanisole in trifluoroacetic acid. The synthetic tricosapeptide was tested for effect on the impaired blastogenic response of phytohemagglutinin-stimulated T-lymphocytes of a uremic patient with pneumonia. The synthetic tricosapeptide was found to have restoring activity, which was approximately equal in potency to that of our synthetic deacetyl-thymosin β4.
