Application

Growth Hormone Releasing Factor (GHRF) is an amino acid peptide that induces the release of growth hormone via GPCR receptor GHRH-R. N-terminal fragments and modified fragments are used to study the biological roles of GHRF.

Native human GRF(1-44)-NH2(hGRF44) is subject to biological inactivation by both enzymatic and chemical routes. In plasma, hGRF44 is rapidly degraded via dipeptidylpeptidase IV (DPP-IV) cleavage between residues Ala2 and Asp3. The hGRF44 is also subject to chemical rearrangement (Asn8-->Asp8, beta-Asp8

Conditions have been developed for the site-specific pegylation (NH2-terminus, side-chain and carboxy-terminus) of a potent analog of growth hormone-releasing factor, [Ala15]-hGRF(1-29)-NH2. These pegylated peptides were prepared by solid-phase peptide synthesis using the Fmoc/tBu strategy, and were fully characterized by analytical

In order to prepare GRF analogs with high activity in vivo, a strategy was undertaken to stabilize the peptide to dipeptidylpeptidase IV (DPP-IV), a protease found in plasma which inactivates native human and bovine GRF by cleavage of the Ala2-Asp3

The ability of human (h)GRF-(1-29)NH2 to stimulate GH secretion was studied in cannulated adult rats. In order to suppress endogenous GRF secretion and the inhibitory action of hypothalamic somatostatin (SRIF), rats were anesthetized with sodium pentobarbital. Intravenous administration of hGRF-(1-29)NH2
