Design of the Synthetic Route for Peptides and Proteins Based on the Solubility Prediction Method. I. Synthesis and Solubility Properties of Human Proinsulin C-Peptide Fragments
For the classical solution synthesis of human epidermal growth factor (h-EGF), four protected peptide derivatives, Boc-Lys(Cl-Z)-Trp-Trp-Glu(OcHex)-Leu-Arg(Tos)-OBzl (5), Boc-Glu(OcHex)-Arg(Tos)-Cys(MeBzl)-Gln-Tyr(Br-Z)-Arg(Tos)-Asp(OcHex)-Leu-OH (13), Boc-Tyr(Br-Z)-Ile-Gly-OH (16), and Boc-Cys(MeBzl)-Asn-Cys(MeBzl)-Val-Val-Gly-OH (22) were synthesized to build up the sequence corresponding to 31–53.

For the protection of the carboxyl group of amino-acids during peptide synthesis, the acid-labile diphenylmethyl ester group was used. N-Trityl-(i.e., triphenylmethyl), N-formyl-, or N-o-nitrophenylsulphenyl-amino-acid diphenylmethyl esters were converted by known methods into the corresponding ester hydrochlorides. The deblocking of the carboxyl group was accomplished either by the action of dilute
For the classical solution synthesis of human epidermal growth factor (h-EGF), five protected peptide derivatives, Boc-Leu-Asp(OcHex)-Lys(Cl-Z)-Tyr(Br-Z)-Ala-OH (5), Boc-Val-Cys(MeBzl)-Met-Tyr(Br-Z)-Ile-Glu(OcHex)-Ala-OH (12), Boc-Tyr(Br-Z)-Cys(MeBzl)-Leu-His-Asp(OcHex)-Gly-OH (18), Boc-Cys(MeBzl)-Pro-Leu-Ser(Bzl)-His-Asp(OcHex)-Gly-O H (23) and Boc-Asn-Ser(Bzl)-Asp(OcHex)-Ser(Bzl)-Glu(OcHex)-OH (28) were synthesized to build up the sequence corresponding to 1–30.

The present invention pertains to the field of immunotherapy. More specifically, the present invention provides a method for differentiating myeloid-derived suppressor cells (MDSC) into non suppressive cells, by administering a compound blocking the interaction between SIRPa and CD47 to a patient in need thereof, in order to reduce MDSC-induced immunodepression and consequently allow appropriate immune responses in cancers, infectious diseases, vaccination, trauma, autoimmune diseases, chronic inflammatory diseases and transplantation.
