Medical treatment of acromegaly is based on either suppressing pituitary GH secretion or inhibiting GH action by preventing interaction with its receptor in order to suppress the elevated levels of IGF1. AZP-3813 is a 16-amino acid, bicyclic peptide antagonist of the GH receptor (GHR) derived from peptide sequences discovered using a unique, cell-free in vitro transcription-translation system screened against the human GHR, and that was optimized by rational design to increase...

The key metabolic hormone, leptin, acts in part through the liver to regulate glucose homeostasis, as well as the maturation of both adipocytes and osteoblasts. These actions have been demonstrated to be mediated by insulin-like growth factor binding protein 2 (IGFBP-2), independent of its ability to bind IGF1. The effects of IGFBP-2 on adipocyte and osteoblast maturation can be localized to a short peptide sequence within the unique heparin binding domain (HBD-1) of IGFBP-2. ...

Prader-Willi syndrome (PWS) is a rare complex endocrine disease characterized by hyperphagia and abnormal food-related behaviors that contribute to severe morbidity and early mortality and to a significant burden on patients and caregivers. There are no approved treatments for hyperphagia in PWS. Patients with PWS have increased circulating levels of the orexigenic hormone acylated ghrelin (AG) with a relative deficit of unacylated ghrelin (UAG). These abnormalities in AG and ...
