Wr. Schoen et al., STRUCTURE-ACTIVITY-RELATIONSHIPS IN THE AMINO-ACID SIDE-CHAIN OF L-692,429, Bioorganic & medicinal chemistry letters, 4(9), 1994, pp. 1117-1122
Development of L-692,429, the prototype compound of a novel class of g
rowth hormone (GH) secretagogues(1), focused on defining the structure
-activity relationships in the amino acid sidechain. Modification of t
he dimethyl-beta-alanine group revealed the basic amine as an essentia
l pharmacophore for GH releasing activity. Evaluation of a variety of
amino-substituted derivatives led to the identification of analogs wit
h improved potency.
