[0099] Such cyclic peptide is, similar to previously known BNPs, considered to bind to a receptor NPR-A (also known as GC-A) having a guanylate cyclase domain and promote the production of cyclic guanosine monophosphate (cGMP), and has activities such as, for example, diuretic action, vasodilation, renin-aldosterone secretion suppressing action, sympatholytic activity and hypertrophy suppressing action. It has a superior drug efficacy and effect, particularly an excellent immediate effect, as compared to BNP.

[0100] In addition, as described hereinbelow, the above cyclic peptide can be used as an ingredient of an external preparation for a dermatitis therapeutic/prophylactic, a rhinitis therapeutic/prophylactic, an alopecia therapeutic/prophylactic, a hair growing agent, a hair growth stimulant, an antipruritic, etc., or as an ingredient of a skin-care product, a quasi-drug or a cosmetic product. The above cyclic peptide can also be used as an alternative for BNP in an medicament utilizing the activity of BNP as above, e.g., in an medicament for hypertension, unstable angina, acute myocardial infarction, edematous diseases, renal failure, cardiac failure, immune diseases, obesity or metabolic syndrome.

[0101] In another embodiment of the present invention, in the cyclic peptide of the invention, X.sup.1-X.sup.12 in the Formula (I) may be defined as one or more selected from the group consisting of following (1)-(12):

[0102] (1) X.sup.1 denotes Gly, Val, Ala, Ser or Thr,

[0103] (2) X.sup.2 denotes Arg, Gln or His,

[0112] (11) X.sup.11 denotes Leu, Met, Ile, Val or Ala, and

[0113] (12) X.sup.12 denotes Gly, Ser or Ala.

[0114] A preferred cyclic peptide of the present invention is a cyclic peptide of Formula (I), wherein X.sup.2 denotes Arg, X.sup.4 denotes Met, X.sup.6 denotes Ser, X.sup.7 denotes Ser, and/or X.sup.10 denotes Gly (SEQ ID NO: 2).

[0115] Furthermore, in another embodiment of the invention, in the cyclic peptide of the invention, the amino acid sequence expressed by Formula (I) may be selected from SEQ ID NOs: 3-8 and SEQ ID NOs: 16-75.

[0116] Furthermore, in the cyclic peptide of the invention, the amino acid sequence expressed by Formula (I) is preferably selected from the amino acid sequences expressed by the Formula (I-a)-Formula (I-e):

##STR00004##

[0117] wherein, the line connecting two Cys denotes a disulfide bond.

[0118] Each of the amino acid sequences expressed by these Formulae (I-a)-(I-e) is the cyclic part of human BNP (Formula (I-a)), swine BNP (Formula (I-b)), rat BNP (Formula (I-c)), rabbit BNP (Formula (I-d)) and murine BNP (Formula (I-e)), respectively. Therefore, the cyclic peptide having such an amino acid sequence will exhibit the aforementioned effects with more certainty. Because swine BNP cyclic peptide is consistent with those of avian (SEQ ID NO: 8,

[0119] Cys-Phe-Gly-Arg-Arg-Ile-Asp-Arg-Ile-Gly-Ser-Leu-Ser-Gly-Met-Gly-Cys, wherein, 1st Cys and 17th Cys form a disulfide bond), bovine (SEQ ID NO: 9,

[0120] Cys-Phe-Gly-Arg-Arg-Leu-Asp-Arg-Ile-Gly-Ser-Leu-Ser-Gly-Leu-Gly-Cys, wherein, 1st Cys and 17th Cys form a disulfide bond), feline (SEQ ID NO: 10,

[0121] Cys-Phe-Gly-Arg-Arg-Leu-Asp-Arg-Ile-Gly-Ser-Leu-Ser-Gly-Leu-Gly-Cys, wherein, 1st Cys and 17th Cys form a disulfide bond), canine (SEQ ID NO: 11,

[0122] Cys-Phe-Gly-Arg-Arg-Leu-Asp-Arg-Ile-Gly-Ser-Leu-Ser-Gly-Leu-Gly-Cys, wherein, 1st Cys and 17th Cys form a disulfide bond), and ovine (SEQ ID NO: 12,

[0123] Cys-Phe-Gly-Arg-Arg-Leu-Asp-Arg-Ile-Gly-Ser-Leu-Ser-Gly-Leu-Gly-Cys, wherein, 1st Cys and 17th Cys form a disulfide bond), BNP cyclic peptides derived from these organisms also have similar effects as the cyclic peptide of the present invention. Among those mentioned above, it is particularly preferred that the amino acid sequence expressed by Formula (I) is the amino acid sequence expressed by Formula (I-a). In another embodiment of the invention, the cyclic peptide may be expressed by SEQ ID NOs: 16-75.

[0124] The cyclic peptide of the present invention encompasses a derivatized form of said cyclic peptide. Such a derivative can be used as such, as an active substance, or also used as a prodrug.

[0125] A derivative of the present invention can be obtained by adding (modifying) a known substituent to certain group of an amino acid in the cyclic peptide such as, for example, a hydrogen atom, hydroxyl group, carboxy group, amino group or imino group, or replacing it with a known replaceable substituent. Modification include, but not limited to, chemical modifications such as, for example, glycosylation, acetylation, phosphorylation and lipidation, to an amino acid within the cyclic peptide.

[0126] The addition (modification) or replacement of an amino acid within the cyclic peptide can occur in one group, or can occur in more than one group at the same time. Any known substituents can be used as long as being capable of replacing above groups and it goes without saying that such substituents naturally include, for example, protecting groups such as BOC.

[0127] The cyclic peptide of the invention further includes a mutated form of said cyclic peptide. Namely, a mutant of the present invention can be obtained by deleting an amino acid in the cyclic peptide, replacing it with or adding it another amino acid. The number of amino acid to be deleted, replaced with other amino acids or added is 4 or less, more preferably 3 or less, even more preferably 2 or less, and particularly preferable 1 or less. It also goes without saying that the deletion, replacement or addition of amino acids in the cyclic peptide may occur concurrently and independently to each other.

[0128] An amino acid that is capable of being replaced with another amino acid can be, in the case of human BNP (Formula (I-a)), exemplified as follows, without being limited thereto. The third amino acid from left, Gly, may be replaced with either Val, Ala, Ser or Thr. The forth amino acid from left, Arg, may be replaced with either Gln or His. The fifth amino acid from left, Lys, may be replaced with Arg. The sixth amino acid from left, amino acid, Met, may be replaced with either Leu or Ile. The ninth amino acid from left, Ile, may be replaced with Val. The twelfth amino acid from left, Ser, may be replaced with either Gln, Val, Ala, Thr, Leu, Ile or Met. The thirteenth amino acid from left, Ser, may be replaced with either Val, Ala or Thr. The fourteenth amino acid from left, Gly, may be replaced with Arg. The fifteenth amino acid from left, Leu, may be replaced with either Met, Ile, Val or Ala. The sixteenth amino acid from left, Gly, may be replaced with either Ser or Ala. Table 32 summarizes examples of replaceable amino acids in the cyclic peptide of the invention, though the invention will not be limited thereto.

[0129] Cyclic peptides in which one amino acid has been replaced include such as, for example, SEQ ID NOs: 16-44, though the invention will not be limited thereto. Cyclic peptides in which two amino acids have been replaced include such as, for example, SEQ ID NO: 45-58, though the invention will not be limited thereto. Yet cyclic peptides in which three amino acids have been replaced include such as, for example, SEQ ID NOs: 59-70, though the invention will not be limited thereto. Furthermore, cyclic peptides in which four amino acids have been replaced include such as, for example, SEQ ID NOs: 71-75, though the invention will not be limited thereto. It also goes without saying that five or more amino acids can be replaced by appropriately combining the aforementioned amino acid.

[0130] Deletion of one to several amino acids can take place in similar manner to the replacement of the aforementioned amino acids with other amino acids.

[0131] The number of amino acid which are to be deleted or replaced with other amino acids or added may be determined such that the cyclic peptide will have 80% homology, preferably 90% homology to the cyclic peptide of the invention.

[0132] In addition, the present invention may be a mutant as described above, and a derivative thereof. As long as it retains the effect of the invention, any mutant or a derivative thereof is encompassed in the cyclic peptide according to the invention. In another embodiment, it has at least a BNP activity. For purpose of improving the activity of the cyclic peptide of the invention, prolonging the effect of the invention, and/or increasing storage stability of the cyclic peptide of the invention, the cyclic peptide of the invention or the amino acids constituting said peptide may be altered in an appropriate manner. For example, an amino acid in the cyclic peptide of the invention may be chemically modified, some amino acids constituting the cyclic peptide may be deleted or replaced with other amino acids, and/or new amino acids may be added.

[0133] For example, the C-terminal group COOH of one Cys of the cyclic peptide may be replaced with COOR.sup.1, CONHR.sup.1 or CONR.sup.12, and/or the N-terminal group NH.sub.2 of the other Cys of the cyclic peptide may be replaced with NHC(O))R.sup.1 or N(C(O)R.sup.1).sub.2. Here, each appearance of R.sup.1 is independently a branched or straight hydrocarbon group or an alkylene glycol chain or sugar chain having 1 to 20 carbon atoms. The number of carbon atoms in R.sup.1 is preferably 1 to 10, more preferably 1 to 5, yet more preferably 1 to 2.

[0134] Pharmaceutically acceptable salts include, without being particularly limited, as the cyclic peptide of the invention or a derivative, such as for example, a salt with an inorganic base, a salt formed with an organic base, a salt formed with an inorganic acid, a salt formed with an organic acid, a salt formed with a basic or acidic amino acid. Examples of suitable salt formed with inorganic base include such as, for example, an alkaline metal salt such as a sodium salt and potassium salt; an alkaline earth meal salt such as a calcium salt and magnesium salt; and an aluminum salt and ammonium salt. Examples of suitable salt formed with organic base include such as, for example, a salt with an alkyl amine such as trimethyl amine or triethyl amine; a salt formed with a heterocyclic amine such as pyridine and picoline; a salt formed with an alkanol amine such as ethanol amine, diethanol amine and triethanol amine; a salt formed with a cycloalkyl amine such as cyclohexyl amine and dicyclohexyl amine; a salt formed with an alkylene diamine derivative such as N,N-dibenzylethylenediamine. Examples of suitable salt formed with inorganic acid include such as, for example, a salt formed with hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid or phosphoric acid. Examples of suitable salt formed with organic acid include such as, for example, a salt formed with a monocarboxylic acid such as formic acid, acetic acid, trifluoroacetic acid and propionic acid; a salt formed with a polyvalent carboxylic acid such as fumaric acid, oxalic acid and maleic acid; a salt formed with a oxycarboxylic acid such as tartaric acid, citric acid, succinic acid and malic acid; a salt formed with a sulfonic acid such as methane sulfonic acid, benzezne sulfonic acid and p-toluene sulfonic acid; and a salt formed with benzoic acid. Examples of suitable salt formed with a neutral amino acid include such as, for example, a salt formed with glycine, valine or leucine; examples of suitable salt formed with a basic amino acid include such as, for example, a salt formed with arginine, lysine or ornithine; and examples of suitable salt formed with an acidic amino acid include such as, for example, a salt formed with aspartic acid acid or glutamic acid.

[0135] Among those mentioned above, a cyclic peptide composed of the amino acid sequence expressed by Formula (I) or a pharmaceutically acceptable salt is preferred. Namely, it is preferred that the amino acid sequence expressed by Formula (I) is not replaced.

[0136] A method for producing the cyclic peptide of the present invention, a derivative and pharmaceutically acceptable salt thereof may employ, without being particularly limited, for example, any known chemical synthetic or genetic engineering methods.

[0137] When the amino acid sequence as above is chemically synthesized, it may be synthesized by any chemical synthetic method, or any known method for peptide synthesis, for example, or solid-phase or liquid-phase synthetic method. Moreover, any commercial synthesizer (e.g., SHIMADZU Corporation: PSSM-8) may be used for synthesis.

[0138] A disulfide bond can be formed in the amino acid sequence, for example, by DMSO oxidation method or iodine oxidation method without being particularly limited. In this case, an intramolecular disulfide bond can be formed by treating a free sulfhydryl group or a sulfhydryl group protected by a protecting group with either DMSO or iodine (I2) to result in said cyclic peptide.

[0139] A protecting group includes such as, for example, 4-methylbenzyl group (Bzl (4Me)), trityl group (Trt), tert-butyl group, N-(acetyl) aminomethyl group (Acm). Deprotection can be carried out through appropriate treatment corresponding to these protecting group, for example, for 4-methylbenzyl group by treating with a strong acid, and for N-(acetyl) aminomethyl group by treating with iodine.

[0140] Next, if necessary, the cyclic peptide is derivatized to result in a derivative. Derivatization can be carried out by known method. Alternatively, a derivative of the cyclic peptide can be produced at the time of peptide synthesis by introducing in advance a substituent into the amino acid constituting the cyclic peptide.

[0141] Then, if necessary, a pharmaceutically acceptable salt is produced by ion exchange of the cyclic peptide or derivative thereof. Ion exchange can be carried out, for example, by bringing into the contact the cyclic peptide or derivative thereof with a desired acid or base.

[0142] On the other hand, when the peptide is synthesized by genetic engineering, it can be synthesized by any known method such as, for example, methods described in Sambrook J. et al., Molecular Cloning, A Laboratory Manual (4th edition) (Cold Spring Harbor Laboratory Press (2012)). For instance, a DNA fragment coding for the amino acid sequence expressed by Formula (I) is prepared at first. Preparation of the DNA fragment can be performed, for example, if it is a case in which the DNA fragment codes for the amino acid sequence expressed by Formula (I-a), by amplifying the DNA fragment by PCR using a vector comprising a full-length human BNP gene as template and primers designed to synthesize a defined DNA region. Alternatively, a DNA fragment can be chemically synthesized.

[0143] Then, the amplified DNA fragment is ligated into an appropriate vector to obtain a recombinant vector for protein expression. Next, the vector for protein expression is allowed to be taken up by target cells and the transformed cells are selected. Finally, the protein produced by the cells (i.e., the protein composed of the amino acid sequence expressed by Formula (I)) is collected.

[0144] Formation of disulfide bond, derivatization and salt formation in the collected protein can be carried out as described above.

[0145] The identification of the compound of interest such as a cyclic peptide can be confirmed by known procedures such as, for example, reverse-phase HPLC or mass spectroscopy.

[0146] The presence or absence of BNP activity in the obtained compound can readily be confirmed by known means. For instance, it can be confirmed by examining cGMP producing activity in NPR-A receptor-expressing cells.

[0147] 2. External Preparation

[0148] Secondly, the external preparation of the present invention is explained.

[0149] The external preparation of the present invention comprises one or more cyclic peptide and/or a derivative thereof and/or a pharmaceutically acceptable salt thereof as described above. If two or more cyclic peptides are used, the number of different cyclic peptide to be mixed is not limited, though 2 to 3 are preferred in terms of preparation cost and convenience. It includes SEQ ID NO: 19, 29, 33, 36, 39 and 43, for example, but the invention is not limited to these and these cyclic peptide can appropriately be combined as long as it does not interfere the effect of the invention.

[0150] 2.1 Application

[0151] The external preparation of the present invention can be used for following uses, for example, without being particularly limited, and in each case exerts remarkable effect which had not previously been achieved. The external preparation of the present invention is not limited to any particular use, and can be used as a pharmaceutical product, a quasi-drug and/or a cosmetic product depending on its drug efficacy and effect.

[0152] Hereinbelow, the invention will be described in detail for each of its use.

[0153] (1) Therapeutic/Prophylactic for Dermatitis

[0154] The external preparation of the present invention can be a a therapeutic and/or prophylactic for dermatitis.

[0155] The external preparation of the present invention can, upon being applied onto the subject's skin or mucosa suffering dermatitis, quickly relieve or eliminate various perceptible symptoms and conditions that are or can be caused by dermatitis such as pruritus, soreness (pain), hot sensation, tautness, erythema, infiltration, papule, lichenification, crust, exudation or skin desiccation, improving the symptoms of dermatitis. In addition, the external preparation of the present invention does not cause any irritation at the site of application.

[0156] Furthermore, such action of the external preparation comprising the cyclic peptide of the invention is effected more quickly and for prolonged time period as compared to that of an external preparation comprising BNP having the tail part. Although reasons for these advantageous effects of the cyclic peptide over such BNP are not clear, the cyclic peptide of the invention is considered to have an advantageous structure for binding to its receptor (NPR-A receptor) over BNP, thereby enabling faster binding to the NPR-A receptor in the vicinity of the affected site and at the same time prolonging its binding time. Moreover, it is considered that its relatively quick binding to the NPR-A receptor near the affected site can prevents the cyclic peptide from diffusing out of the affected site via bloodstream, etc., enabling it to stay around the affected site for relatively long time.

[0157] The external preparation of the present invention doese not only suppress or prevent inflammation in dermatitis but also acts to restore and/or retain the barrier function of skin. Here, skin's barrier function works for protecting skin against entry of stimuli and saprophytes from external environment or for retaining moisture. The external preparation restores the barrier function, and thus able to prevent the progress or exacerbation of inflammation. The barrier function of skin is greatly affected by the alignment state of corneocytes in the corneum, i.e., state of skin texture and moisturization. The external preparation of the present invention acts to improve skin texture and to moisturize skin. Therefore, its effects of restoring and maintaining skin barrier function are also obvious.

[0158] The external preparation of the present invention is also effective on skin symptoms commonly called acne, i.e., such as comedones, red papule, pustula, cysts/tuberosity.

[0159] Moreover, a quick relief or elimination of perceptible symptoms or conditions will reduce the burden of the subject (patient) and improve the QOL of the patient, while preventing the patient from being bothered by itch or soreness and from acting to damage the affected site, for example, touching or scratching. This effect of the external preparation of the present invention to relieve or eliminate perceptible symptoms or conditions is, in general, exhibited within 10 minutes, preferably within 5 minutes, more preferably within 3 minutes after application.

[0160] In addition, the external preparation of the present invention can treat dermatitis in which steroid dermatosis has been developed, or dermatitis that is intractable by other common drugs for dermatitis therapy such as steroid and tacrolimus, for example dermatitis for which a sufficient therapeutic effect cannot be achieved by these formulations, or dermatitis which is resistant to these formulations, or dermatitis for which the use of these formulations is not suitable or desirable. Conventional widely-used steroid external preparations have significant problems upon terminating application that the severity returns to the pre-application level and that a rebound phenomenon may occur and exacerbate the condition. The external preparation of the present invention has no such problems as a rebound phenomenon.

[0161] Dermatitis is in general a disease which causes inflammation in skin or mucosa. Dermatitis is normally accompanied with one or more symptoms selected from acute eczema symptoms such as erythema, infiltrative erythema, papule, vesicle, pustula, infiltration, incrustation and desquamation; chronic eczema symptoms such as lichenification and pigmentation; and scales, crust (scab) attachment, scratching, scratch scar, prurigo nodularis, erosion, edema, oozing and squamatization.

[0162] Dermatitis herein is not particularly limited as long as it is a disease which is accompanied with inflammation in skin or mucosa and includes such as, for example, eczema and atopic dermatitis such as chronic eczema, dyshidrotic eczema, infantile xerotic eczema; contact dermatitis such as allergic contact dermatitis and primary irritant contact dermatitis; seborrheic dermatitis; asteatotic dermatitis; autosensitization dermatitis; stasis dermatitis; urticaria such as allergic urticaria (e.g., alimentary urticaria and drug-induced urticaria) and nonallergic urticaria (e.g., physical urticaria, solar urticaria and cholinergic urticaria); insect bite; drug eruption; psoriasis such as plaque psoriasis, guttate psoriasis, erythrodermic psoriasis, pustular psoriasis and psoriasis arthropathica; prurigo such as chronic prurigo, acute prurigo, gestational prurigo and nodular prurigo; rosacea; rosacea-like dermatitis; cutaneous vasculitis such as cutaneous allergic vasculitis; cutaneous pruritus such as systemic cutaneous pruritus, localized cutaneous pruritus, senile cutaneous pruritus and gestational pruritus; solar dermatitis; erythrosis; nummular dermatitis; localized scratching dermatitis; perioral dermatitis; pompholyx; keratosis pilaris; lichen planus, dyshidrotic eczema, dyshidrosis, miliaria and acne vulgarisacne vulgaris. The external preparation of the present invention can be applied to the therapy and prophylaxis of any of these diseases.

[0163] The external preparation of the present invention exerts an excellent effect especially on eczema, atopic dermatitis, contact dermatitis, seborrheic dermatitis, insect bite, allergic or nonallergic urticaria and psoriasis, preferably on eczema, atopic dermatitis, contact dermatitis and insect bite, more preferably on eczema and atopic dermatitis. Therefore, the external preparation of the present invention can be used for the purpose of the therapy and prophylaxis of at least one or more dermatitis selected from above-mentioned group.

[0164] (2) Ingredients of Cosmetic or Skin-Care Product

[0165] The external preparation of the present invention may be an ingredient for a cosmetic or skin-care product.

[0166] The external preparation of the present invention will, upon being applied to skin and/or mucosa, provide moisture to the applied site and exert moisturizing effect, preventing skin from dryness and roughness. In cases where corneum is present at the site of application, it exerts an effect of improving skin texture there. It also provides and retains moderate elasticity and flexibility of skin and mucosa, softens skin, gives skin and mucosa resilience and firmness. Moreover, it improves wrinkles (including fine and large wrinkles) and flabbiness at the applied site, and further diminishes the appearance of dullness and spots.

Working Examples

[0289] Hereinbelow, the present invention is further specifically illustrated by working examples. It should be noted that the present invention is not limited by these working examples.

[0290] 1. Preparation of the Cyclic Peptide

[0291] Firstly, a cyclic peptide composed of the amino acid sequence expressed by Formula I-a is synthesized.

[0292] Specifically, a linear peptide consisting of 17 amino acids was formed by sequentially binding amino acids by solid-phase peptide synthesis using a peptide synthesizer. Subsequently, protecting groups at Cys1 and Cys17 were detached before treating with iodine GO to form a cysteine binding between oxidatively same amino acid residues, thereby forming a cyclic peptide.

[0293] A composition comprising the obtained cyclic peptide was purified by reverse-phase high performance liquid chromatography (reverse-phase HPLC) and then lyophilized to yield a purified cyclic peptide as white powder.

[0294] Mass spectroscopy was performed on the obtained cyclic peptide.

[0295] Conditions for HPLC are shown below:

[0296] Apparatus: Agilent 1100

[0297] Flow rate: 1.0 ml/min

[0298] Eluent A: 0.1% trifluoroacetic acid/water

[0299] Eluent B: 0.1% trifluoroacetic acid/acetonitrile

[0300] Gradient: 80% Eluent B, isocratic

[0301] Conditions for Mass spectroscopy (MS) are shown below:

[0302] Apparatus: Thermo Finnigan LCQ Advantage

[0303] Ionization method: electrospray ionization

[0304] Analytical method: ion trapping

[0305] The observed results, m/z=901.83 ([M+2H].sup.2+), m/z=1801.84 ([M+H].sup.+), confirmed that above peptide is in agreement with the theoretical values of the molecular weight (1802.07) and the mass number (1800.8069) calculated from the composition formula of the cyclic peptide of interest (C.sub.72H.sub.120N.sub.24O.sub.24S.sub.3).

[0306] Furthermore, the purity of the above peptide was measured by HPLC using following conditions:

[0307] Column: Discovery C18, 4.6 mm250 mm, particle diameter 5 micron

[0308] Column temperature: room temperature

[0309] Eluent A: 0.1% trifluoroacetic acid/water

[0310] Eluent B: 0.1% trifluoroacetic acid/acetonitrile

[0311] Gradient: 10 to 30% Eluent B/20 minutes

[0312] Flow rate: 1.2 ml/min

[0313] Temperature: room temperature

[0314] Injected volume: 20 l

[0315] Detector: UV detector (detection wavelength: 215 nm)

[0316] The result of measurement confirmed that the purity of the obtained protein was 99.2%.

[0317] 2. Preparation of Formulation

[0318] 2.1 Preparation of Gel Formulation

[0319] Preparation of a gel-based formulation comprising a cyclic peptide composed of the amino acid sequence expressed by Formula I-a (in the working examples below, B ring is referred to mean a cyclic peptide expressed by such Formula I-a) (B ring gel formulation, Working Examples) and a gel-based formulation comprising human BNP (BNP gel formulation, Comparative Examples) were carried out as follows.

[0320] 0.1 g of methyl-p-hydroxybenzoate (trade name: Mekkins-M, Ueno Fine Chemicals Industry, Ltd.), 0.2 g of phenoxyethanol and 3.0 g of 1,2-pentanediol were weighed into one same vessel, heated to 60 to 70 C. to make a homogenous solution, and this solution was poured into a mixer.

[0321] Next, added into the mixer 6.0 g of concentrated glycerin, and then the mixture of 0.44 g of carboxyvinyl polymer (trade name: Carbopol 940, Lubrizol Advanced Materials Corporation) and 0.08 g of xanthane gum (trade name: KELTROL T, CP Kelco, Inc.), and the mixuter was stirred with a paddle until they dispersed sufficiently.

[0322] Then 83.95 g of purified water was gradually added with stirring with a paddle. The mixer was heated to 70 to 80 C. while stirring with a paddle or disper until the dispersed contents were dissolved to give a solution. Subsequently, the disper was stopped and the solution was cooled immediately after confirming that the contents in the solution were dissolved. When the temperature of the mixer reached approximately 40 C., 6.0 g of Lubrajel NP from Ashland Inc. (glycerin 2.7 g, carboxyvinyl polymer 0.06 g, sodium polyacrylate 0.018 g, water 3.222 g) was added to the solution, mixed uniformly with a paddle. Subsequently, 0.230 g of potassium hydroxide was further added to neutralize the solution, then the rotation of the paddle was stopped when the temperature of the mixer reached 25 C. to prepare a gel base.

[0323] Next, 20.1 mg of the the cyclic peptide (B ring) composed of the amino acid sequence expressed by Formula I-a was dissolved in 144 mL of physiological saline to obtain B ring solution. 0.131 mL of this solution was admixed with 10 g of the gel base obtained as described above, and the mixture was stirred uniformly to prepare a gel based formulation (B ring gel formulation) containing B ring at a concentration of about 1 M (about 1.8 g/g). Similarly, gel based formulations containing B ring at concentrations of about 0.3 M (about 0.54 g/g), about 0.5 M (about 0.9 g/g) and about 2.0 M (about 3.6 g/g) were prepared. In the working examples below, as long as it is specifically described otherwise, B ring gel formulation used contained B ring at a concentration of about 1 M.

[0324] Next, 20.5 mg of human BNP-32 (American Peptide Company) was dissolved in 118 mL of physiological saline to obtain BNP solution. 0.2 mL of this solution was admixed with 10 g of the gel base obtained as described above, and the mixture was stirred uniformly to prepare a gel based formulation (BNP gel formulation) containing BNP-32 at a concentration of about 1 M. Similarly, gel based formulations containing BNP-32 at concentrations of about 0.5 M and 2.0 M were prepared. In the working examples below, as long as being specifically described otherwise, BNP gel formulation used contained BNP at a concentration of about 1 M.

[0325] 2.2 Preparation of Nasal Drop

[0326] A nasal drop comprising the cyclic peptide (B ring) composed of the amino acid sequence expressed by Formula I-a (B ring nasal drop, Working Examples) and a nasal drop comprising human BNP (BNP nasal drop, Comparative Examples) were prepared as follows.

[0327] Firstly, the cyclic peptide (B ring) composed of the amino acid sequence expressed by Formula I-a was dissolved in physiological saline, the concentration was adjusted to prepare B ring nasal drop containing B ring at a concentration of about 1 mol/l (about 1.8 g/g).

[0328] Next, B ring nasal drop was filled in a quantitative nasal spray container (AS ONE Corporation) and the amount ro be sprayed for each administration was adjusted to 100 l (0.1 ml), resulting B ring nasal drop.

[0329] Similarly, a BNP nasal drop comprising human BNP (American Peptide Company) at a concentration of 1 mol/1 was obtained, filled in a quantitative nasal spray container (AS ONE Corporation), and the amount ro be sprayed for each administration was adjusted to 100 l (0.1 ml), resulting BNP nasal drop.

[0330] 3. Confirming Therapeutic Effect on Dermatitis

[0331] 3.1 Confirming the Effect of B Ring Gel Formulation

[0332] For subjects suffering various dermatitis, B ring gel formulation as described was applied onto the affected site, and changes in symptoms before and after the application were observed. When possible, as a comparative example, BNP gel formulation as described was applied onto another affected site on the same subject where B ring gel formulation had not been applied, and changes in symptoms before and after the application were observed. For pruritus, VAS (Visual Analogue Scale) was used for evaluating each affected site on 10 stages.

[0333] The examination results are shown in Tables 1 to 7 along with age, sexuality, symptoms of the subject, and formulation given to the subject.

[0334] As shown in Tables 1 to 8, in all subjects, or in all dermatitis of any symptoms, emission or elimination of various symptoms of dermatitis was observed at the site where B ring gel formulation was applied.

[0335] Specifically, when B ring gel formulation was applied, remission or elimination of pruritus was observed immediately after the application. Generally in dermatitis, patients tend to scratch where pruritus was felt, potentially causing severer dermatitis. Such a remarkable remission or elimination of pruritus in this manner can consequently prevent aggravation of dermatitis.

[0336] In all cases, the effects of B ring gel formulation were superior to those with BNP gel formulation. Specifically, B ring gel formulation had faster-acting and longer-lasting effects as well as more potent antipruritic effect as compared with BNP gel formulation. It was confirmed that these effect cannot be obtained by the gel base.

[0337] 3.2 Comparing B Ring Gel Formulation to Gel Base by Two-Sided Application

[0338] For subjects suffering various dermatitis, either B ring gel formulation or the gel base was applied to the affected site, and changes in symptoms before and after the application were observed (Table below).

[0339] 4. Confirming Cosmetic Effect

[0340] Effects of a cosmetic comprising B ring were evaluated from the results obtained using a gel formulations, a bath agent and a hair cosmetic product (shampoo or rinse) or body soap comprising the B ring to confirm their effects.

[0341] 4.1.1 Confirming Skin-Improving Effect (Comparing B Ring Gel Formulation to BNP Gel Formulation)

[0342] The B ring gel formulation or BNP gel formulation was applied to subjects. The B ring gel formulation was applied on the right cheek or eye of each subject, the BNP gel formulation on the left cheek or eye, and changes in skin conditions were observed and compared (Table below). The changes in skin conditions were determined based on physical sensory evaluation by the subject and our objective observation as physicians.

TABLE-US-00010 TABLE 10 Case Applied site: method Pre-application symptoms Post-application symptoms F1 Right: B ring gel formulation Presented with wrinkles, cheek 2 min after application, wrinkles on eye corner Age: 69 0.5 mol, 1 application flabbiness, pigmentation on and forehead were shallowed, skin was full. Sex: female eye corner. After 3 min, cheek flabiness and skin texture were improved, and pigmentation on eye corner was less prominent. After application for 3 days, large wrinkle on cheek was shallowed, flabbiness was improved, skin was firm, resilient, full and moisturized.

Sex: female Skin was flexible, soft and moisturized. Left: applied gel base No improvement observed in desiccation and flare after 3 min. F5 Right: B ring gel formulation Presented with wrinkles on both 2 min after application, wrinkles on both corners of Age: 28 2 mol, 1 application corners of eye, and desiccation. eyes were less prominent, cheek dryness was improved, Sex: female skin was moisturized and flexible. Perioral desiccation was remitted and skin became full and flexible. Left: applied gel base No improvement observed in desiccation and wrinkles after 2 min at gel-applied site on the left. F6 Right: B ring gel formulation Presented with skin desiccation. 1 min after application, itches were remarkably remitted. Age: 30 2 mol, 1 application oily skin and red papules around After 3 min, skin desiccation and flare were improved, Sex: female nose, and light erythema and and skin was moisturized and flexible with improved rough skin texture. texture. Red papules around nose almost disappeared, combination state of desiccation and oily skin was improved, and skin is kept healthy. Left: applied gel base 3 min after application, desiccation, flare and itches are left, and seborrhea and papules around nose were not remitted.

[0343] Table below summarizes examples in which B ring gel formulation was applied without applying two-sided. The changes in skin conditions were determined by similar method as described above.

TABLE-US-00011 TABLE 11 Case Method of application Pre-application symptoms Post-application symptoms G1 B ring gel formulation 1 mol Presented with cheek flare, open After B ring application, flare was repressed, skin Age: 50 1 application pores, rough and hard skin texture. texture was improved, skin was moisturized and Sex: female softened.

G4 B ring gel formulation 2 mol Presented with miliaria and 3 min after application at B ring-applied site, miliaria Age: 50's 1 application pruritus accompanied with flare. was prevented, flare and itches were remitted. Sex: male

[0344] Accordingly, it was shown that B ring of the present invention has a skin moisturizing effect and is capable of improving skin texture, and that it is also effective in improving skin, for instance in lightening (spots, dullness) and anti-aging (flabbiness, resilience, large wrinkles) as well as in improving mucosal condition such as roughened lips.

[0345] In all subjects, a remarkable improving effect in skin and its persistence was observed at the site where B ring gel formulation had been applied as compared to where BNP gel formulation had been applied. Specifically, effects as follows were observed at the site where B ring gel formulation had been applied as compared to where BNP gel formulation had been applied with significance: effects of improving skin, moisturizing skin, improving skin texture, providing skin with resilience and firmness, softening skin, suppressing skin desiccation, fading fine wrinkles, supplying and keeping skin with water and oil, shallowing and diminishing crow's feet, eliminating skin rawness, eliminating and suppressing itches, relieving skin roughness and maintaining skin condition healthy.

[0346] Particularly, in subjects in their 20's or 30's, remarkable effects such as improving or eliminating wrinkles, improving cheek flabbiness, and supplying and keeping skin with moisture, water and oil, and the effects such as giving skin firmness and tightness, lifting up cheeks, eliminating skin rawness and relieving skin roughness were observed at the site where B ring gel formulation had been applied as compared to the site where BNP gel formulation had been applied, and these effects were greater as compared to those at BNP gel-applied site.

[0347] Moreover, in subjects in their 40's and 50's, remarkable effects such as improving flabbiness, large wrinkles and desiccation, giving skin firmness, fading dullness and spots were exhibited immediately after the application of B ring gel formulation, and these effects were greater as compared to those upon applying BNP gel formulation.

[0348] The effects exhibited significantly faster in B ring gel formulation as compared to BNP gel formulation. Specifically, effects were confirmed in most cases such that wrinkles were vanished or started to vanish and faded and skin was made full and resilient. These effects lasted for at least several hours thereafter. No irritating symptoms were observed with application of B ring gel formulation.

[0349] FIG. 1 shows a photograph of the right-side face of a subject in her 60's after the application of B ring gel formulation. In this subject, effects were observed at 20 minutes after the application of B ring gel formulation such that the skin were moist, provided with moisture, complexion and softness, given firmness, improved texture, provided with resilience, and large wrinkles faded. This result was compared to BNP gel formulation as a comparative example, indicating that the cyclic peptide of the invention is not only effective on fine wrinkles but also is effective on wrinkles and flabbiness, and that it is also effective in fading spots and dullness.

[0350] 4.1.2 Confirming Skin-Improving Effect (Comparing B Ring Gel Formulation to Gel Base)

[0351] In order to examine the presence or absence of the contribution by the gel base to the effects of B ring gel formulation and BNP gel formulation, three subjects were administered B ring gel formulation on their right face and the gel base on the left, and changes in skin conditions on the subject's faces were observed (Table below).

TABLE-US-00012 TABLE 12 Case Applied site: method Pre-application symptoms Post-application symptoms H1 Right: B ring gel formulation Rough, stiff and dry skin texture. After 2 min skin was felt soft. Age: 48 Left: applied gel base Skin was tingling. Open pores and rough skin texture were Sex: female not improved. H2 Right: B ring Sensitive dry skin with roughness 1 min after application, skin tingling sensation stopped. After Age: 26 and tingling. 2 min, B ring-applied side was felt more moisturized. Sex: female Left: applied gel base 1 min after application, skin was still tingling. After 2 min, the subject felt that moisturizing effect is weak. H3 Right: Sensitive skin with tingling. Age: 30 Left: applied gel base Skin was tingling and temporally red. Skin desiccation was Sex: female not improved. White scales were observed.

[0352] As a result, all subjects felt tingling sensation at the site where the gel base was applied, and dry feeling of skin was not improved. Also, in all subjects, no effect (e.g., improved skin texture or closed pores) was observed at the site where the gel base was applied. On the other hand, in all subjects, the skin area on which B ring gel formulation was applied has been moisturized and softened.

[0353] 4.2 Observation on Mucosal Condition Upon Application of B Ring Gel Formulation.

[0354] The B ring gel formulation was applied to normal subjects who had symptoms of roughened lips, and changes in mucosal condition were observed (Table below). The changes in mucosal conditions were determined based on physical sensory evaluation by the subject and our objective observation as physicians.

TABLE-US-00013 TABLE 13 Case Applied site: method Pre-application symptoms Post-application symptoms I1 B ring 1 mol Cracks on mouth corner with pain. Skin became moisturized soon after application.

Sex: male Left: gel base 2 min after application, cracks on mouth corner and pain were 1 application not improved.

[0355] Accordingly, it was confirmed that the cyclic peptide of the invention has an activity of improving mucosal condition and it also has an immediate effect in such activity.

[0356] 4.3 Observation on Scalp/Hair Condition Upon Application of B Ring Gel Formulation.

[0357] The B ring gel formulation was applied to normal subjects who had symptoms of scalp/hair, and changes in conditions of scalp and hair were observed (Table below). The changes in scalp/hair were determined based on physical sensory evaluation by the subject and our objective observation as physicians.

TABLE-US-00014 TABLE 14 Case Applied site: method Pre-application symptoms Post-application symptoms J1 B ring 0.5 mol Presented with desiccation and After 2 min, itches were removed, scalp was relieved from roughness Age: 40's 1 application itches of head. and desiccation and moisturized.

[0358] Accordingly, BNP cyclic peptide of the present invention can provide and keep scalp and hair with moisture, give them moderate water and oil, improve and prevent desiccation, and clean scalp and hair. It is further effective for suppressing itch and dandruff of scalp and also effective for preventing thinning or loosing hair, for growing hair and promoting or stimulating hair growth, and forcing hair growth, and furthermore effective for an improvement in alopecia after illness or postnatal alopecia.

[0359] 4.4 Observation on Skin Condition Upon Using Bath Agent Comprising B Ring

[0360] Subjects were given bath in 37 to 41 C. hot water comprising B ring dissolved at 0.01 M (100 ml of 20 M B ring solution dissolved in 200 L hot water) once a day for 14 days, and skin condition of the subjects was compared to the case of hot water alone (Table 14). The changes in skin conditions were determined based on physical sensory evaluation by the subject and our objective observation as physicians.

[0373] 5.2 Case Summary

[0374] In the cases of the subjects having female pattern alopecia, male pattern alopecia, alopecia universalis, ophiasis or alopecia areata multilocularis as described above, a significant decrease in falling hair was observed, and the area of terminal hair growth was expanded, and the growth of the terminal hair was also faster, when B ring gel formulation of the working example was applied compared with BNP gel formulation as a comparative control (See, FIG. 2). Addingly, the existing hairs obtained resilience and their elasticity was increased. In all cases, symptoms were significantly improved as compared to the cases when BNP gel formulation of the comparative example was applied. Accordingly, B ring gel formulation had superior effects on the symptoms described above as compared to BNP gel formulation.

[0375] In addition, the B ring gel formulation could improve seborrhea, clean scalp and suppress dandruff. It also prevents hairs from turning white, grows black hairs, and improves thinning of hair. Moreover, it exhibits an antipruritic effect within 10 minutes, demonstrating an excellent immediate effect. It could suppress ithes within 3 minutes after application in some cases.

[0379] 6.2 Case Summary

[0380] In all cases described above, both rhinorrhea and nasal obstruction were quickly improved or eliminated when B ring nasal drop of the working example had been applied as compared to the case when BNP nasal drop of comparative example had been applied. Accordingly, B ring nasal drop had faster effect than BNP nasal drop. Addingly, the effect of B ring nasal drop was more than equal to that of BNP nasal drop, and because the effect lasted for longer time period, it can suppressing recurrence of symptoms.

[0381] The following table summarizes information from the cases described above, within the range recognizable at the time when symptoms of nasal obstruction and rhinorrhea were improved.

[0382] 7. Analysis of Binding State of Human BNP and Type A Receptor

[0383] The superior pharmacological effects of the B ring-compound of the invention on various diseases relative to conventional BNP has been explained so far with reference to data based on respective clinical cases. Such pharmacological effects is also supported by the result of the conformation analysis of the compound performed by the inventors, which is explained by following experimental report for reference.

[0384] In order to investigate binding state of human BNP (BNP-32) and its receptor Type A receptor (NPR-A), an in silico analysis was performed by homology modeling using conformation. Swiss-Pdb viewer and SWISS-MODEL were used for modeling.

[0385] 7.1 Template Structure

[0386] Firstly, prior to the above analysis, a template structure for investigation on binding state of human BNP and Type A receptor was selected. As this template structure, the conformation of the complex of rat NPR-A and rat ANP peptide (PDB ID: 1T34) were used. Rat NPR-A is a homodimer composed of A and B strands. The conformation of such rat NPR-A has been determined by X-ray crystalline structural analysis such that 21 residues from Cys7 to Arg 27 of rat ANP were bound. The conformation of rat NPR-A was obtained from the database of protein conformation, Protein Data Bank. Amino acid homology between human NPR-A and rat NPR-A is 85%.

[0387] 7.2 BNP Peptide Model

[0388] In the present study, as BNP peptide model, a resion from Cys10 to Arg30 in human BNP (BNP-32, SEQ ID NO: 13, Ser-Pro-Lys-Met-Val-Gln-Gly-Ser-Gly-Cys-Phe-Gly-Arg-Lys-Met-Asp-Arg-Ile-Ser-Ser-Ser-Ser-Gly-Le u-Gly-Cys-Lys-Val-Leu-Arg-Arg-His), i.e., an amino acid sequence (SEQ ID NO: 14, Cys-Phe-Gly-Arg-Lys-Met-Asp-Arg-Ile-Ser-Ser-Ser-Ser-Gly-Leu-Gly-Cys-Lys-Val-Leu-Arg) was used. In the peptide model above, the amino acid sequence of B ring of the invention corresponds to a resion from Cys10 to Cys26 of human BNP above, i.e., Cys-Phe-Gly-Arg-Lys-Met-Asp-Arg-Ile-Ser-Ser-Ser-Ser-Gly-Leu-Gly-Cys (SEQ ID NO: 15).

[0389] 7.3 Homology Modeling

[0390] In order to speculate the amino acid residues that are involved in binding of human NPR-A and human BNP, a complex model in which BNP peptide is bound to human NPR-A was constructed by homology modeling. Specifically, human BNP peptide model was constructed based on the template structure of rat ANP peptide, and human NPR-A model structure based on the template structure of rat NPR-A.

[0391] Next, residues that are involved in the interaction was speculated from the amino acid residues detected between human BNP peptide model and human NPR-A.

[0392] The results showed that BNP peptide model is bound to human NPR-A dimer being sandwiched between the A strand and B strand. Amino acids in the amino acid sequence, e.g., the amino acid sequence used as the model (SEQ ID NO: 14, Cys-Phe-Gly-Arg-Lys-Met-Asp-Arg-Ile-Ser-Ser-Ser-Ser-Gly-Leu-Gly-Cys-Lys-Val-Leu-Arg) are expressed as amino acid (number). Namely, the number in parentheses denotes the relative position counted from the N-terminal of the amino acid sequence, for example, Phe2 indicates an amino acid that is the second Phe counted from the N-terminal of the peptide model.

[0393] In the constructed complex model, the presence of a hydrophobic bond by Phe2 side chain, a hydrogen bond by Phe2 main chain, and hydrogen bonds by side chains of Arg4, Met6, Arg8, Ser10 and Ser11 were speculated between BNP peptide model and the A strand of NPR-A. Phe2, Arg4, Met6, Arg8, Ser10 and Ser11 in BNP peptide model correspond to Phell, Arg13, Met15, Arg17, Ser19 and Ser20 in human BNP respectively. Namely, this result suggests that these amino acid residues in human BNP is likely to be the residues that contribute to NPR-A activation.

[0394] 7.4 Discussion

[0395] Thus, by in silico conformation analysis, it was speculated that, in human BNP, the amino acid residues that are present in its cyclic part are likely to contribute to NPR-A activation, whereas the amino acid residues present in the tail part are not. It was also suggested that BNP cyclic structure is a smaller molecule than BNP-32 and therefore capable of binding easily and quickly. In fact, a clinical application of a peptide having BNP cyclic structure confirmed that BNP cyclic structure provides faster therapeutic effect than BNP-32. This clinical result is consistent with that of the in silico analysis that BNP cyclic structure contributes to NPR-A activation and can bind to it more easily and quickly than BNP-32. Thus, BNP cyclic structure has a superior therapeutic effect than a general BNP peptide, and therefore is a different substance.

[0396] On the other hand, an NMR analysis revealed that ANP does not take any particular conformation in a solution where its conformation greatly wobbles; this is considered to be similar for BNP. Namely, in human BNP, assuming that the amino acid residues in the cyclic part contribute to its binding to human NPR-A, it is speculated that the amino acid residues in the tail part rather prevent human BNP from entering into the narrow BNP binding site sandwiched between A and B strands of human NPR-A due to its large wobbling. Therefore, it is considered that the cyclic part of human BNP is a relatively smaller molecule than conventionally known human BNP, enabling itself to enter into BNP binding site of NPR-A more easily and quickly. Moreover, it is speculated that the the cyclic part of human BNP has a higher affinity to human NPR-A than BNP-32. This supports the clinical outcomes described herein that the peptide having only the cyclic part of BNP exhibits therapeutic effect faster than BNP-32.

[0397] In order to speculate the effect of BNP cyclic structure (B ring) from non-human species on human Type A receptor, complex models of human NPR-A and BNP rings from pig, bird or rat were generated to surmise interaction. The results suggested that a sufficient effect of the invention can be expected by using BNP ring from non-human animal species (e.g., pigs, birds or rats), as long as it shows an affinity to human NPR-A.

[0398] 8. Speculating Replaceable Amino Acid Residues in BNP Cyclic Moiety

[0399] Using the constructed model structure of the complex, replaceablity of amino acid residues other than those considered to be involved in the interaction was investigated.

[0400] Specifically, in order to investigate whether the peptide in which amino acid residue that is not assumed to be involved in the interaction has been replaced with another amino acid is capable of binding to NPR-A, a mutant model of BNP was generated to analyze the interaction. Swiss-Pdb viewer was used for modeling.

[0401] Specifically, amino acid residues Gly12, Lys14, Asp16, Ile18, Ser21, Ser22, Gly23, Leu24 and Gly25 in human BNP were targeted for the investigation on their replaceability with other amino acids in terms of following points: [0402] No steric hindrance caused by binding to NPR-A. No interatomic collision observed in the model structure of NPR-A and BNP. [0403] No influence on electrostatic potential on surface. [0404] No large increase in intramolecular energy value (no unnatural angle or twist caused in intermolecular binding). [0405] No non-naturally occurring hydrogen bond formed between the strands of NPR-A and BNP and within BNP strand. [0406] No cavity (cavity, niche) formation.

[0407] Among those described above, intramolecular energy was calculated by ComputeEnergy command of Swiss-Pdb viewer. Intramolecular energy was calculated from the sum of the length of binding, bond angle, twist and binding energy, etc. in the unit kilojoule/mol (Kj/mol).

[0408] The results of analysis indicated the presence of replaceable amino acid residues in Gly12, Lys14, Ile18, Ser21, Ser22, Leu24 and Gly25 among the amino acid residues of human BNP (Table below).

TABLE-US-00028 TABLE 28 human BNP Replaceable amino acid Gly12 Ala, Val, Ser, Thr Lys14 Arg Asp16 none Ile18 Val Ser21 Thr, Ala, Val, Gln, Leu, Ile, Met Ser22 Thr, Ala, Val Gly23 none Leu24 Ala, Val, Ile, Met Gly25 Ala, Ser

[0409] Accordingly, even when the replacement of the amino acid corresponding to those described in the table above took place in the cyclic part of human BNP, i.e., the peptide expressed by the Formula I-a, it was suggested that the peptide replaced in such a way exerts a similar effect as the peptide composed of the amino acid sequence expressed by Formula I-a.

[0410] 9. Confirming Therapeutic Effect of the Cyclic Peptide with Amino Acid Replacement

[0411] Next, cyclic peptides with some replaced amino acid were subjected to following examination in order to confirm their effect. The methods for preparing the above cyclic peptide and confirming amino acid sequence of the prepared peptide were same as the method for preparing the cyclic peptide as described above and Mass spectroscopy method.

[0412] 9.1 Confirming Effects on Scalp or Hair

[0413] The obtained cyclic peptide was prepared in purified water at 3, 15, 30, 100 or 500 g/ml and applied to the affected site. Each of formulations A to E in the table indicates the concentration of cyclic peptide at 3, 15, 30, 100 or 500 g/ml, respectively.

[0414] The result described above demonstrated that the cyclic peptide of the invention exhibits a similar effect as the cyclic peptide expressed by Formula I-a even if some amino acids of the cyclic peptide have been replaced.

[0415] Specifically, it has effects of preventing hair loss at the applied site, stimulating hair growth or promoting hair growth, giving hair resilience and elasticity, increasing volume of hair and dramatically decreasing falling hairs when it was applied to the site of alopecia or hair growth stimulation, etc. It also has effects of nourishing hair, promoting hair growth stimulation, improving/preventing thinning of hair at the applied site. In this case, the stimulated hair tends to become a terminal (non-white) hair. Moreover, these effect exhibit significantly faster as compared to other active agents conventionally used in alopecia therapeutics such as BNP such that stimulated hair growth can be confirmed one day after only one application even in the case of an intractable alopecia areata multilocularis or ophiasis. In addition, resulting effects persists remarkably even after terminating application and the stimulated hair keep growing. In the case of AGA or healthy subject it exert immediate effect of providing hair with resilience and elasticity on the following day, increasing the volume, and dramatically decreasing falling hairs, which effects last even after terminating application. It also has an improving and preventing effect on dermatitis. Therefore, it can improve or prevent skin inflammation associated with alopecia. Such effect is advantageous in cases where alopecia has been exacerbated due to skin condition of the applied site (e.g., scalp). Moreover, the external preparation of the present invention exerts a moisturizing and skin texture-improving effects at the applied site when being applied to skin as described above. It can remove and suppress dandruff and itching, while giving moisture to hair and scalp, improving and preventing dryness and keeping hair and scalp healthy. It also can improve seborrhea. On the other hand, when it is used as an alopecia therapeutic/prophylactic, it can be used for the purpose of treating or preventing one or more of applicable alopecia including, for example, those described below, without being particularly limited thereto.

[0416] (Acquired Alopecia)

[0417] (i) Alopecia without accompanying scarring or skin lesion (alopecia areata, male pattern alopecia, seborrheic alopecia, alopecia pityroides, female pattern alopecia, gestational alopecia, malignant alopecia, senile alopecia, alopecia totalis, alopecia areata multilocularis, ophiasis, drug-induced alopecia, cancer chemotherapy-induced alopecia and radiation exposure-induced alopecia, traumatic/mechanical alopecia, malnutrition/metabolic disorder associated alopecia, endocrine dysfunction associated alopecia and telogen effluvium (post partum alopecia, alopecia after high fever)).

[0418] (ii) Alopecia observed in skin lesion or pathologic skin (infection-induced alopecia, tumor-induced alopecia, inflammation-induced alopecia).

[0419] (iii) Scarring alopecia (skin infection-induced alopecia, alopecia induced by infiltration of inflammatory cells).

[0420] (Congenital Alopecia)

[0421] Diffuse alopecia, congenital atrichia, alopecia in hereditary syndromes, localized alopecia, phakomatosis, aplasia cutis, congenital alopecia triangularis.

[0422] It exerts an excellent effect especially on acquired alopecia, preferably on alopecia without accompanying scarring or skin lesion, more preferably on alopecia areata, male pattern alopecia, seborrheic alopecia, alopecia pityroides, female pattern alopecia, gestational alopecia, malignant alopecia, senile alopecia, alopecia totalis, alopecia areata multilocularis, ophiasis, drug-induced alopecia, cancer chemotherapy-induced alopecia and radiation exposure-induced alopecia, traumatic/mechanical alopecia, malnutrition/metabolic disorder associated alopecia, endocrine dysfunction associated alopecia and telogen effluvium. Therefore, the external preparation of the present invention can be used for the purpose of treating or preventing at least one or more alopecia selected from the above-mentioned group.

[0423] One simple application onto aforementioned affected site at 3 g/ml to 500 g/ml improved or eliminated itch, dandruff, scalp redness and inflammation immediately thereafter (immediate effect). A single application stimulated hair growth, grew hair, provided hair with resilience, elasticity and increased volume, and dramatically decreased falling hairs, and these effects started on the day after the application and persisted for one week or more (long-lasting effect). If application was carried on for about one week, these effects are further improved, and even after terminating application, the effects lasted from 1 to 2 weeks such that stimulation of hair growth and restoration of hair continued and there were little or no falling hairs.

[0424] 9.2 Confirming Effects on Skin

[0425] The obtained cyclic peptide was prepared in purified water at 3, 15, 30, 100 or 500 g/ml and applied to affected site. Each of formulations A to E in the table indicates the concentration of the cyclic peptide at 3, 15, 30, 100 or 500 g/ml, respectively. The absence of the effect upon the application of purified water without the peptide confirmed the effect was not a placebo effect.

[0426] The result described above demonstrated that the cyclic peptide of the invention exhibits a similar effect as the cyclic peptide expressed by Formula I-a even if some amino acids of the cyclic peptide have been replaced. Moreover, a similar effect could be obtained by applying the replaced cyclic peptide in a mixture as long as an effective amount of the cyclic peptide is applied.

[0427] Specifically, in subjects having atopic dermatitis or eczema, effects were observed immediately after applying 3 g/ml to 500 g/ml to affected site, including elimination of itches, epithelialization at infiltrated site, papule or scratch, termination of exudation, epithelialization of a crack. Moreover, a single application induced a persistent effect for a week or more.

[0428] When it was applied to healthy or roughened skin, it exerted a moisturizing effect immediately or within a few minutes after application, improving dryness, providing and keeping skin and mucosa with moderate elasticity and flexibility, softening skin, giving skin or mucosa resilience and firmness. Also, fine wrinkles and flabbiness are improved at the applied site, and dullness and spots are further faded. A single application induced a persistent effect for a week or more.

[0429] 9.3 Confirming Nasal Effect

[0430] The obtained cyclic peptide was prepared in physiological saline at 3, 15, 30, 100 or 500 g/ml, and 0.1 ml each was applied to nasal cavity. Each of formulations A to E in the table indicates the concentration of the cyclic peptide at 3, 15, 30, 100 or 500 g/ml, respectively. The absence of the effect upon the application of physiological saline without the peptide confirmed the effect was not a placebo effect.

[0431] The result described above demonstrated that the cyclic peptide of the invention exhibits a similar effect as the cyclic peptide expressed by Formula I-a even if some amino acids of the cyclic peptide have been replaced.

[0432] Specifically, when it was applied to nasal cavity mucosa and/or paranasal cavity mucosa, it can improve or prevent various symptoms associated with rhinitis such as nasal obstruction, rhinorrhea, sneezing and pruritus. Rhinitis also includes, without being particularly limited, for example, infectious rhinitis including acute rhinitis and chronic rhinitis; hypersensitive non-infectious rhinitis including combined (flower hypersensitivity) rhinitis, rhinitis with rhinorrhea, congestive rhinitis, edematous rhinitis and dry-nose type rhinitis; irritant-induced rhinitis including physical rhinitis, chemical rhinitis and radiation rhinitis; and atrophic rhinitis and idiopathic granulomatous rhinitis; sinusitis such as acute sinusitis, chronic sinusitis (maxillary empyema), eosinophilic sinusitis and paranasal cavity mycosis. The external preparation can be used for the purpose of treating or preventing one ore more of the above.

[0433] Combined rhinitis includes, for example, allergic rhinitis including perennial allergic rhinitis and seasonal allergic rhinitis, and nonallergic rhinitis including vasomotor (essential) rhinitis and eosinophilic rhinitis. Rhinitis with rhinorrhea includes, for example, gustatory rhinitis, cold air-induced rhinitis and senile rhinitis.

[0434] Congestive rhinitis includes, for example, drug-induced rhinitis, psychogenic rhinitis, gestational rhinitis, endocrine rhinitis and cold rhinitis.

[0435] Edematous rhinitis includes, for example, aspirin-hypersensitive rhinitis.

[0436] Among those mentioned above, it exerts an excellent effect specifically on hypersensitive non-infectious rhinitis, irritant-induced rhinitis and sinusitis, preferably on hypersensitive non-infectious rhinitis and chronic sinusitis, more preferably on combined (flower hypersensitivity) rhinitis, rhinitis with rhinorrhea, congestive rhinitis, edematous rhinitis and dry-nose type rhinitis, and chronic sinusitis. Therefore, the external preparation of the present invention can be used for the purpose of treating or preventing at least one or more rhinitis selected from the above-mentioned group.

[0437] In terms of its symptoms, for its effects as described above, it can be used for any of rhinitis with sneezing/rhinorrhea, rhinitis with nasal obstruction and rhinitis with both symptoms.

[0438] Immediately after a single application of 0.1 ml of 3 g/ml to 500 g/ml preparation was applied to the affected site in each nasal cavity, nasal discharge was stopped, nasal obstruction was improved, itches in nasal cavity mucosa or sneezing were stopped (immediate effect). A single application of a nasal drop induced persistent effects lasting for one day, or for a week or more in some cases (long-lasting effect). In addition, because it causes no local irritation at all, it can be used safely even in a subject who is not desired to use a nasal drop comprising rhinitis therapeutic that has conventionally been used such as steroid drug due to its strong local irritation.

[0439] Examples of multiple replaceable amino acids in the cyclic peptide of the invention are summarized below, based on working examples as described above, without not being limited thereto.
