Definitions
- the present invention relates to regulators of the physiological function of darelin and their use in connection with the manufacture of pharmaceutical compositions or foods.
- Darrelin is an endogenous ligand (peptide) of a receptor (GHS-R) that binds to growth hormone secretagogue (GHS), a synthetic non-natural substance that promotes growth hormone secretion. Hormone), which was the first substance discovered by the group of the present inventors [(1) and WO01 / 007475]. Initially, darelin was purified from the stomach of rats, but it has been demonstrated that it is also expressed in brain, lung, kidney, spleen, small and large intestine (2-7).
- Ghrelin has also been isolated from cDNA from vertebrates other than rats, such as humans, mice, pigs, chickens, eel, sea lions, pomas, higgies, potatoes, -jimas or dogs, or has been estimated to have cDNA power ( JP-A-2004-2378).
- Darrelin has an activity to increase intracellular calcium ion concentration and a potent growth hormone secretion-promoting activity (1, 8-10), and stimulates appetite, induces obesity (11--14), and improves cardiac function (15-17), has various activities such as promoting gastric acid secretion (18).
- a potent growth hormone secretion-promoting activity (1, 8-10)
- stimulates appetite induces obesity (11--14), and improves cardiac function (15-17)
- has various activities such as promoting gastric acid secretion (18).
- modulation of that function is important not only for subjects suffering from diseases related to Darrelin but also for healthy subjects.
- Darrelin which has been identified so far, is a group of peptides having about 30 or less amino acid residues, and has a structural feature that the amino acid at position 3 is substituted with an acyl group.
- human darelin consists of 28 amino acids, and the serine side chain at position 3 is acylated with a fatty acid (n-octanoic acid).
- the amino acid 3 at the 3-position is essential for the expression of physiological activities such as the increase in intracellular calcium ion concentration of dallelin and the promotion of growth factor secretion (1).
- the amino acid at position 3 of the darelin molecule is usually serine (hereinafter, referred to as “Ser 3 ” or “ser (3)”). No.
- the acyl group used for modification of the amino acid at position 3, which is essential for the biological activity of darelin, is mainly a medium-chain / long-chain fatty acid residue.
- Humans, pigs, sea lions, sheep, dogs, rats, mice, etc., mammals,-birds, such as birds, eel,-fish, such as jimas, terravia, catfish, etc., and amphibians, such as power frogs, are n-otatanyl. [1), (19), and
- acyl modification examples include an n-decanoyl (C10: 0) modification (e.g., Shiga frog, Patent Document 2) and an n-decenoyl (C10: l) modification (20-22).
- n-butanoyl (C4) e.g, Puma
- hexanoyl (C6) e.g., hexanoyl (C6)
- dodecanoyl (C12) are also known (Japanese Patent Application Laid-Open No. 2004-2378).
- Ghrelin-acyl modification is the first example of lipid modification of peptide hormones, and serylhydrido-xyl-group acylation has never been reported as a modification of mammalian proteins.
- the power of the presence of asilyi darelin and non-asiyi darelin in the living body The putative enzyme that catalyzes the transfer of the acyl group to the amino acid residue at position 3 of darelin is probably a novel acyltransferase, which regulates darelin production. Seems important. However, such enzymes have not yet been discovered.
- a substance that modulates rouge at the 3-position amino acid in vivo in a living body functions as a "regulator” or “modulator” of the physiological function (activity) of darrellin) and various physiological physiological functions of ghrelin. It is expected to be useful for enhancing or suppressing the activity.
- Such regulators can be used in the manufacture of a pharmaceutical composition for treating or preventing various physiological disorders related to the physiological activity of dallelin.

In addition, it can be used for animals with anorexia and malnutrition, and animals exhibiting symptoms related to treatment such as health disorders related to excessive appetite and obesity. Or fattening of livestock is also useful for promoting growth and reducing fat
- infusions or liquid diets used during treatment usually contain only minimal nutrients and are not necessarily effective in positively improving physical functioning. Therefore, in order to improve body functions quickly and effectively, there is a demand for the development of infusions and liquid foods with higher functions. Therefore, modulators of the physiological activity of dallelin are considered to be extremely useful for various uses, such as the functional foods described above, infusions, liquid foods, and livestock feeds.
- Another object of the present invention is to provide a method for increasing or decreasing the concentration of modified darelin.
- the present inventors have studied various synthetic-type acyl-modified darelin peptides, and as a result, have found that the effect of the biological activity of darelin can be modified by changing the acyl molecule ( twenty three).
- the present inventors have found that ingested (exogenous) fatty acids are directly used in vivo for acylation of glycerin 3-position amino acids (e.g., Ser (3)).

- mice In the case of mice as described in Examples below, the intake of medium chain fatty acid (MCFA) or medium chain triacylglycerol (MCT) is determined by the total ghrelin (acyl ghrelin and deacil ghrelin) concentration. The production of acyl-modified ghrelin was increased without altering ghrelin.
- MCFA medium chain fatty acid
- MCT medium chain triacylglycerol
- dalelin peptides modified with n-butyryl or n-palmitoyl groups were undetectable after ingestion of the corresponding short (SCFA) or long (LCFA) chains.
- n-heptanoyl ghrelin (a non-natural form of darelin) was produced in the stomach of mice after ingestion of glyceryl n-heptanoate or triheptanoate.
- mice in which darelin is acylated by medium-chain fatty acids medium-chain fatty acids (n-hexanoic acid, n-octanoic acid and n-decanoic acid) or medium-chain triglycerides (glyceryl trihexanoate) are used.
