CJC-1293

CJC-1293

CJC-1293 or Modified GRF 1-29 (sometimes modGRF 1-29), is a tetrasubstituted 29-amino acid peptide hormone, primarily functioning as a growth hormone releasing hormone (GHRH) analog with D-Ala, Gln, Ala, and Leu substitutions at positions 2, 8, 15, and 27 respectively. These substitutions create a much more stable peptide with the substitution at position 2 to prevent DPP-IV cleavage, position 8 to reduce asparagine rearrangement or amide hydrolysis to aspartic acid, position 15 to enhance bioactivity, and position 27 to prevent methionine oxidation.
