Impaired glucose homeostasis in leptin-deficient ob/ob mice is corrected by AZP-3404, a 9-amino acid peptide analog derived from insulin-like growth factor-binding protein 2, a key mediator of leptin action

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. ...

Improved glucose metabolism and decreased weight gain in leptin-resistant, IGFBP2-deficient, db/db mice induced by AZP-3404, a 9-amino acid analog of IGFBP2

Insulin-like growth factor binding protein-2 (IGFBP2) has been demonstrated to be a key mediator of the peripheral actions of leptin, and its deficiency is associated with impaired metabolic function. The metabolic activity of IGFBP2 can be localized to a unique heparin-binding domain (HBD-1) within its structure. AZP-3404 is a 9-amino acid analog of the IGFBP2 HBD-1 that has been demonstrated to increase glucose uptake by differentiated mouse myotubes in vitro, and to increas...
