Description
CONJUGATE OF FINASTERIDE WITH PEPTIDE
TECHNICAL FIELD
The présent invention relates to a compound having a structure conjugating finasterîde and peptide with a covalent bond, and its use for preventing hair loss or promoting hair growth.
BACKGROUND ART
Hair follicle is an organ unique to mammalian skin. The hair follicle is a down10 growth of the primitive epidermis, extending into deeper layers of the skin. At the base of the hair follicle résides a plug of cells known as the follicular or dermal papilla. The papilla is essential in normal cycle of the hair follicle and in growth of the haïr shaft. The hair shaft is a thread-shaped structure made of tightly cohérent épithélial cells filled with keratin filaments and filament aggregating proteins.
Human hair periodically repeats the cycle of anagen, categen and telogen phases, and goes through the process of hair fall and régénération. The hair growth cycle is regulated by hormones or many growth factors. Severe stress or malnutrition may advance the catagen and telogen phases, leading to severe hair loss.
Hair falling out from the scalp îs called hair loss. Hair loss may be caused by 20 various factors including environmental factors such as exposure to weather, light or heat.
etc., and internai factors such as diseases, child bîrth, hormonal sécrétion and change, intake of drugs, nutritive conditions, etc. 5-alpha reductase is a main hormone intervening with the hair loss mechanism (Korean Patent Laid-Open No. 10-2008-0077762). 5-alpha reductase is an enzyme increasing sébum sécrétion by converting testosterone which is a type of androgen into dihydrotestosterone (DHT). Among the various products for preventing hair loss and promoting hair growth in the hair loss market, there are many products aiming at inhibiting the effect of the 5-alpha reductase. Hair loss may also be caused by malnutrition, dry scalp, stress, etc., in addition to enzymatîc reactions (Eunju Ryu, et al., The Journal of Korean Society of Design Culture, 18(2), p. 89-100, 2012). In case of hair loss due to these reasons, hair loss may be prevented and hair growth may be promoted by supplying sufficient nutrition, performing scalp treatment and intaking or administering antioxidant substances.
Regardless of its cause, in the end, hair loss may resuit in exercising a great mental, social and sexual influence, together with loss of pride and self-esteem. In order to treat haîr loss, until now, various substances were used as drugs. but they had disadvantages that they were too expensive or they showed a great individual différence in effect. In addition, as for cosmetic products, plant extracts which are cheaper but hâve a lower effect has been used, but the effect was insignificant.
Treatments and solutions for hair loss hâve remarkably changed over a long period of time. It became possible to hide baldness with wigs, partial wigs and hair extension, but this could not create new hair. Also, the two available drugs (minoxidil and finasteride) known up to date could delay additional hair loss, but could not be actually used for the purpose of inducing the régénération of hair fol lie le. Also, as hair cosmetic products, many hair loss prévention products using plant extracts, etc. hâve been developed, but it has been difficult to find products that hâve an effect on generating new hair growth.
Varions factors are linked together in the progress of hair growth and degeneration. For example, there hâve been many reports using a sériés of growth factors for promoting kératinocyte growth factors, promoting the activity of vascular endothélial growth factors, and promoting the growth of hair by inhibiting the activity of BMP type proteins. However, although such growth factors show excellent effects, an additional process of refolding and more time are required to obtain natural growth factors, and a complex purifying process for removing the pollution source originated from colon bacîllus is required in the purification process. Also, due to its stability and high molecular weight, it could not easily surpass the protective coat of hair, and thus this together with its expensive cost deteriorated its usage.
Also, there is a method which prevents the thinning of hair and makes thinned hair thick again by the antagonism of finasteride against 5a-reductase based on the action of finasteride to androgens. As a représentative example, there is Propecia (Merck U.S.A.) which was approved for its effect and stability by the U.S. Food and Drug Administration (FDA) on December I997 as the first edible hair loss treatment and entered the market as a hair loss treatment the following year. Finasteride is a drug that inhibits 5a-reductase enzyme which converts testosterone, a type of androgen, into DHT causing hair loss. As
DHT génération is inhibited by taking the drug, it plays the rôle of making thinned bald hair thick and long again. However, it takes months for fïnasterîde to exert the effect of preventing hair loss. Also, as for women, there is a high possîbilîty of congénital deformity to occur in the fétus when taking drugs, and as for men, there are fear of side effects such as loss of libido, erectile dysfonction, éjaculation disorder, etc., and pressure that the effect of preventing hair loss can be maintained only when taking the drugs for a lifetime. Thus, there are a lot of limitations for actual clinical use (Korean Patent Laid-Open No. 10-20120I20912).
In this regard, the présent inventors developed Nokkin peptide (Korean Patent LaidOpen No. 10-2010-0085407) composed of amîno acid sequence of SEQ ID No. 3, Keramin2 peptide (Korean Patent Laid-Open No. 10-2009- 0108323) composed of amino acid sequence of SEQ ID No. 2. and WINT peptide (Korean Patent Laid-Open No. 10-2011-0023991) composed of amino acid sequence of SEQ ID No. 1 as peptides that hâve more excellent stability than natural growth factors and may improve the problems caused by the large molecular weight of natural growth factors while having fonctions or effects the same as or similar to natural growth factors. However, the conventîonally used finasteride or peptides composed of amino acid sequences SEQ ID Nos. 1 to 3 still need to be improved in the aspects of improving the effect of preventing hair loss and promoting hair growth, reducing side effects and increasing solubility in water.
DETAILED DESCRIPTION OF INVENTION
TECHNICALTASK
