New growth hormone secretagogue (GHS) analogues were synthesized and evaluated for growth hormone releasing activity. This series derived from EP-51389 is based on a gem-diamino structure. Compounds that exhibited higher in vivo GH-releasing potency than hexarelin in rat (subcutaneous administration) were then tested per os in beagle dogs and for their binding affinity to human pituitary GHS receptors and to hGHS-R 1a. Compound 7 (JMV 1843, H-Aib-(d)-Trp-(d)-gTrp-formyl) showed high potency in these tests and was selected for clinical studies.(1)

Abstract
New growth hormone secretagogue (GHS) analogues were synthesized and evaluated for growth hormone releasing activity. This series derived from EP-51389 is based on a gem-diamino structure. Compounds that exhibited higher in vivo GH-releasing potency than hexarelin in rat (subcutaneous administration) were then tested per os in beagle dogs and for their binding affinity to human pituitary GHS receptors and to hGHS-R 1a. Compound 7 (JMV 1843, H-Aib-(d)-Trp-(d)-gTrp-formyl) showed high potency in these tests and was selected for clinical studies.(1)
