Abstract: The present invention provides a bone repair promoter containing as an active ingredient at least one kind of B-type natriuretic peptide receptor agonist.

Abstract: An effective liquid preparation achieves high bioavailability (BA) of physiologically active peptides or proteins, including ghrelins, that are administered as drugs. Also provided is a method for improving the BA of physiologically active peptides or proteins, including ghrelins, that are subcutaneously injected in aqueous solutions. The liquid preparation contains: a physiologically active peptide or protein, such as ghrelins, as an active ingredient; an acid solution including one or a combination of two or more selected form the group consisting of acetic acid, lactic acid, phosphoric acid, glycine, citric acid, hydrochloric acid, propionic acid, butyric acid, benzoic acid and salts thereof; an alcohol; and a polar organic liquid including one or a combination of two or more selected from the group consisting of N-methyl-2-pyrrolidone, dimethylformamide, dimethylsulfoxide and methylparaben.

Abstract: The present invention aims at providing motilin-like peptide compounds that maintain the gastrointestinal motility stimulating activity of native motilin and which are adapted to have higher absorbability upon transmucosal administration. Motilin derivatives were designed and synthesized in consideration of the pathway for the degradation of motilin at a site of its transmucosal absorption and the maintenance of motilin's physiological activity and compounds characterized by substitutions for the amino acid at position 21 of native motilin have been found to show higher absorbability upon transmucosal administration and yet maintain the same activity as motilin.

Abstract: An isolated chimeric peptide consisting of one or two added peptides and an object peptide wherein the added peptide is bonded to the N-terminus, the C-terminus or both of the object peptide, wherein if the added peptides are bound to both terminals, the two added peptides may be the same or different; and physiological activity of the object peptide is still retained, wherein the object peptide is a natural physiologically active peptide selected from the group consisting of an atrial natriuretic peptide, a brain natriuretic peptide, a C-type natriuretic peptide, motilin, a glucagon-like peptide 1, parathyroid hormone, and calcitonin, or a derivative of any thereof, wherein the derivative has one or more amino acid(s) deleted from the amino acid sequence of a natural physiologically active peptide and has the desired physiological activity.

Abstract: A peptide of the following (I) or (II). (I) a peptide represented by the formula B, A-B, B-C or A-B-C in which A, B and C each is represented by the following (1), (2) and (3) and, when it is bonded to other object peptide, it is able to extent the half-life in plasma as compared with the object peptide where the physiological activity of the object peptide is still retained. (II) a peptide comprising a reversed sequence of the peptide of (I); a sequence which is represented by A-B in (I) and A or B is reversed; a sequence which is represented by B-C in (I) and B or C is reversed; or a sequence which is represented by A-B-C in (I) and A, B, C, A and B, B and C or A and C is reserved.

Abstract: A pharmaceutical for promoting neogenesis or regeneration of pancreatic ? cells which produces and secretes insulin and for promoting insulin production in ? cells, comprising ghrelin or a derivative thereof as an effective component.

Abstract: A novel dosage regimen of GLP-1 receptor agonists causes little or no side effects or drug interactions and is suitable for improving insulin resistance. Also provided is an insulin resistance improver for use in the dosage regimen. The dosage regimen comprises repeatedly administering, preferably in a non-invasive manner, a GLP-1 receptor agonist at least before eating for a predetermined period of time to create a condition similar to what is observed with postprandial temporary secretion of the endogenous GLP-1 receptor agonist, rather than administering it continuously. This creates a similar or enhanced variation in the plasma levels of GLP-1 receptor agonist as compared to the circadian variation of the endogenous GLP-1 receptor agonist in a healthy individual. A pharmaceutical composition for use in the dosage regimen containing GLP-1 receptor agonist as an active ingredient is also provided.
