Abstract
Description
Composition for preventing hair loss and promoting hair growth containing extract of Cornarus conchocapis
[0001] The present invention relates to a composition for promoting hair growth comprising an extract of Connarus conchocarpus as an active ingredient, and to a composition for preventing hair loss and promoting hair growth containing a component that suppresses male pattern baldness, suppresses alopecia areata, and induces new hair growth or hair growth promotion.
[0002] This patent application claims priority to Republic of Korea Patent Application No. 10-2024-0092487, filed with the Korean Intellectual Property Office on July 12, 2024, the disclosure of which is incorporated herein by reference.
[0003]
[0004] In modern society, hair loss is a common cosmetic and psychological problem for both men and women, and demand for its prevention and treatment is steadily increasing. Hair loss is caused by a variety of factors, including genetics, hormonal imbalances, stress, medications, aging, and environmental pollution, acting singly or in combination. Its pathophysiological mechanisms are also highly complex.
[0005] Hair grows through a cycle of growth (anagen), regression (catagen), and resting (telogen) phases. However, an imbalance or shortening of this cycle can lead to miniaturization of hair follicles and hair loss, resulting in alopecia. Alopecia is classified into congenital, acquired, and pathological alopecia based on its cause. Among the acquired alopecia types, male pattern baldness and alopecia areata are known to have a high incidence and relatively clear pathogenesis.
[0006] Male pattern baldness is caused by dihydrotestosterone (DHT) binding to the androgen receptor (AR) on hair papilla cells, which induces the expression of hair growth inhibitors such as DKK1, TGF-β, and IL-6. This suppresses the Wnt / β-catenin signaling pathway, leading to apoptosis and shortened growth phase of hair follicle cells. Furthermore, the conversion of testosterone to DHT by 5α-reductase further accelerates this process.
[0007] Alopecia areata is an autoimmune disease in which the immune privilege of hair follicles is disrupted and the JAK-STAT signaling pathway is overactivated. Increased secretion of cytokines such as IFN-γ and IL-15 promotes inflammatory gene expression through phosphorylation of JAK1 / 2 / 3 and STAT1 / 3 / 5, and CD8 + Hair follicle cells are destroyed by T cell invasion and excessive granzyme B and perforin secretion. Furthermore, activation of the JAK-STAT pathway inhibits the transition of hair follicle stem cells from the resting phase to the growth phase, contributing to persistent hair loss.
[0008] To date, Minoxidil, Finasteride, steroids, immunosuppressants, and phototherapy have been suggested as hair loss treatments. However, their effectiveness is limited due to the reported side effects of long-term use, such as increased body hair, skin irritation, decreased sexual function, depression, and Cushing's syndrome.
[0009] Therefore, there is an urgent need to develop a safe and effective hair loss treatment material of natural origin that has few side effects and can comprehensively regulate hair follicle and papilla cells functions.
[0010] Connarus conchocarpus F.Muell. is an evergreen shrub of the legume family, native to tropical regions such as New Guinea and Queensland. Its main components, flavonoids and phenolic compounds, are known to possess antioxidant, anti-inflammatory, and antibacterial properties. While it has traditionally been used to treat digestive and respiratory ailments, scientific research on its hair loss prevention and hair growth promotion effects is limited.
[0011]
[0012] The present inventors have diligently researched and developed an effective hair loss treatment. As a result, they have discovered that Connarus conchocarpus extract exhibits excellent hair loss prevention and treatment effects, as well as hair growth promotion, due to its physiological effects, including promoting dermal papilla cell proliferation, activating the Wnt / β-catenin pathway, suppressing JAK and AR expression, and inhibiting 5α-reductase activity. This has led to the completion of the present invention.
[0013] Accordingly, an object of the present invention is to provide a pharmaceutical composition for preventing or treating alopecia comprising an extract of Connarus conchocarpus.
[0014] Another object of the present invention is to provide a method for producing a Cornarus conchocapis extract.

[0060] The extraction time of the extract according to one embodiment of the present invention is, for example, 1 hour to 100 hours, 1 hour to 90 hours, 1 hour to 80 hours, 1 hour to 72 hours, 1 hour to 70 hours, 1 hour to 60 hours, 1 hour to 50 hours, 1 hour to 40 hours, 1 hour to 30 hours, 1 hour to 20 hours, 1 hour to 10 hours, 10 hours to 100 hours, 20 hours to 100 hours, 30 hours to 100 hours, 40 hours to 100 hours, 50 hours to 100 hours, 60 hours to 100 hours, 70 hours to 100 hours, 80 hours to 100 hours, 90 hours to 100 hours, 10 hours to 80 hours, 20 hours to 60 hours, 40 hours to It may be, but is not limited to, 60 hours, 2 to 10 hours, 3 to 10 hours, 3 to 5 hours, 60 to 80 hours, or 65 to 75 hours.
[0061] The Cornarus conchocapis extract used in the present invention can be manufactured into a powder form by additional processes such as reduced pressure distillation and freeze drying or spray drying.
[0062] In one embodiment of the present invention, the Cornarus conchocapis extract is a solvent extract selected from the group consisting of glycol solvents, water, alcohol, or a combination thereof.
[0063] The above solvent is a means for effectively extracting effective ingredients from the Cornarus conchocapis plant, and the type and physiological activity of the extracted ingredients may vary depending on the characteristics of each solvent.
[0064] For example, glycol solvents may include, but are not limited to, butylene glycol, propylene glycol, ethylene glycol, and dipropylene glycol. These solvents have excellent water solubility and skin penetration ability, and thus can provide extracts suitable for use in cosmetic and over-the-counter drug compositions.
[0065] Water or purified water can be used as a solvent to extract mainly water-soluble polysaccharides, flavonoids, phenolic compounds, etc. through high-temperature hot water extraction or leaching methods.
[0066] For example, alcohol solvents can be low molecular weight alcohols such as, but not limited to, methanol, ethanol, n-propanol, isopropanol, n-butanol, n-propanol, n-butanol, 1-pentanol, 2-butoxyethanol, etc. These are effective for extracting not only polar compounds but also some non-polar bioactive substances. These solvents can be used alone or as aqueous solutions at a concentration of 20 to 80% (v / v), and can also be applied in composite solvent compositions.
[0067] In one embodiment of the present invention, the extract is as follows:
[0068] (a) the glycol solvent is a glycol solvent having a concentration of 20% (v / v) to 80% (v / v); or
[0069] (b) The alcohol has a concentration of 20% (v / v) to 80% (v / v).
[0070] In one embodiment of the present invention, the Connarus conchocarpus extract is a hot water extract of Connarus conchocarpus residue extracted with a glycol solvent at a concentration of 20% (v / v) to 80% (v / v).
[0071] In one specific embodiment of the present invention, the Connarus conchocarpus extract can be prepared in various ways depending on the type and concentration of the solvent used. In particular, the concentration of the extraction solvent affects the dissolution efficiency, stability, and physiological activity of the active ingredient, so it is important to set it within an appropriate concentration range.
[0072] Specifically, the glycol solvent extract uses a solution prepared by diluting a glycol solvent such as butylene glycol, propylene glycol, etc. in purified water at a concentration of 20% (v / v) to 80% (v / v) as an extraction solvent, and can be obtained by soaking or stirring and extracting the plant body of Cornarus conchocapis with this solution.
[0073] Additionally, water extracts are prepared by first extracting with a glycol solvent (20-80% v / v) and then secondary extracting the remaining solid residue with hot water (purified water at around 100°C). This hot water extraction can additionally secure water-soluble components (e.g., polysaccharides, water-soluble phenols, flavonoids, etc.) that were not extracted during the first solvent extraction, making it advantageous for developing compositions exhibiting complex physiological activities.
[0074] Meanwhile, alcohol extracts are obtained by steeping or stirring Cornarus conchocapis in an extraction solution containing low-molecular-weight alcohols such as methanol, ethanol, propanol, and butanol diluted in purified water at a concentration of 20% (v / v) to 80% (v / v), enabling the extraction of not only polar components but also some semi-polar components. Ethanol is a preferred solvent due to its high safety, especially for applications in food and pharmaceuticals.
[0075] In this way, the Cornarus conchocapis extract of the present invention can be prepared using a single solvent such as a glycol solvent, water, alcohol, etc. or a combination of stepwise extractions, and by setting the concentration of the extraction solvent in the range of 20% (v / v) to 80% (v / v), it is possible to stably secure an effective ingredient suitable for the purpose.
[0076] The concentration of the glycol solvent or alcohol is 20% (v / v) to 80% (v / v), 20% (v / v) to 75% (v / v), 20% (v / v) to 70% (v / v), 20% (v / v) to 60% (v / v), 20% (v / v) to 55% (v / v), 20% (v / v) to 50% (v / v), 20% (v / v) to 45% (v / v), 20% (v / v) to 40% (v / v), 20% (v / v) to 35% (v / v), 20% (v / v) to 30% (v / v), 20% (v / v) to 25% (v / v), 25% (v / v) to 80% (v / v), 30% (v / v) to 80% (v / v), 35% (v / v) to 80% (v / v), 40% (v / v) to 80% (v / v), 45% (v / v) to 80% (v / v), 50% (v / v) to 80% (v / v), 55% (v / v) to 80% (v / v), 60% (v / v) to 80% (v / v), 65% (v / v) to 80% (v / v), 70% (v / v) to 80% (v / v), 75% (v / v) to 80% (v / v), 30% (v / v) to 70% (v / v), 40% (v / v) to 60% (v / v), 25% (v / v) to It may be, but is not limited to, 35% (v / v), 40% (v / v) to 60% (v / v), 45% (v / v) to 55% (v / v), or 65% (v / v) to 75% (v / v).
[0077] In one embodiment of the present invention, the extract has the properties of inhibiting the expression of 5-α-reductase, inhibiting the expression of androgen receptor, inhibiting the activity of JAK (Janus kinase), activating the Wnt / β-catenin signaling pathway, or a combination thereof.
[0078] The Cornarus conchocapis extract according to the present invention can exhibit hair loss prevention or treatment effects by acting on various molecular biological mechanisms related to hair loss, such as 5-α-reductase inhibition, androgen receptor inhibition, JAK signaling pathway inhibition, and Wnt / β-catenin signaling pathway activation. Each of the above mechanisms is a scientifically established target in the pathophysiology of hair loss, and it has already been proven through various literature and clinical studies that when acting alone or in combination, it exhibits a hair loss improvement effect.
[0079] First, 5-alpha-reductase is an enzyme that converts testosterone, a male hormone, into dihydrotestosterone (DHT), a more potent androgen. DHT binds to androgen receptors in hair papilla cells, inducing the expression of hair loss-related genes, resulting in hair follicle atrophy and shortened growth phase. Accordingly, finasteride and dutasteride, which are 5-alpha-reductase inhibitors, have been approved by the FDA as treatments for male pattern baldness, and have been reported to increase hair count and improve hair thickness when taken long-term. Inhibiting this enzyme, as in the extract of the present invention, can scientifically induce hair loss improvement effects.
[0080] Furthermore, the androgen receptor (AR) is a key target protein that binds to DHT and induces transcription of hair loss genes. It is known that increased AR expression accelerates the progression of male pattern baldness. Some studies have reported that AR inhibition also affects the restoration of Wnt / β-catenin signaling and the activation of hair follicle stem cells. RNA-based candidate substances that indirectly regulate AR are actively being studied in the preclinical stage. Therefore, a composition that inhibits AR expression, such as the extract according to the present invention, can effectively alleviate hair loss progression.
[0081] The JAK (Janus kinase) signaling pathway is a key pathway driving the pathogenesis of autoimmune hair loss, particularly in alopecia areata. Inflammatory cytokines such as IFN-γ and IL-15 induce phosphorylation of JAK1 / 2 / 3 and STAT1 / 3 / 5, which leads to CD8+ T cell invasion into hair follicles and destruction of hair follicle cells. Accordingly, JAK inhibitors such as tofacitinib and ruxolitinib have clinically demonstrated hair regrowth effects in patients with alopecia areata, and in 2022, the JAK inhibitor baricitinib was approved by the FDA as a treatment for alopecia areata. Therefore, the extract of the present invention, which inhibits JAK activity, can be effectively applied to inflammatory alopecias such as alopecia areata.
[0082] The Wnt / β-catenin signaling pathway is an essential pathway that induces the survival and anagen entry of hair follicle stem cells. When the activity of this pathway is suppressed, hair regeneration is inhibited and telogen effluvium is induced. There are research results that show that while hair loss is induced in a mouse model in which the β-catenin gene is deleted, inducing the expression of Wnt3a or β-catenin promotes hair follicle regeneration and hair growth. In fact, minoxidil has also been reported to exhibit a hair growth effect by indirectly activating the Wnt / β-catenin pathway. The extract of the present invention can induce the survival of hair follicle cells and recovery of the growth cycle by showing activity that increases the expression of Wnt3a and β-catenin.
[0083] Thus, the Cornulus conchocapis extract of the present invention can contribute to the treatment of hair loss through each mechanism alone. When combined, it can provide even more effective treatment by blocking various causes of hair loss or promoting hair growth. This scientific and clinical background supports the claim that the composition of the present invention is a technology sufficiently effective in the prevention or treatment of hair loss.
[0084] In one embodiment of the present invention, the alopecia is selected from the group consisting of androgenetic alopecia, female pattern alopecia, inflammatory alopecia, alopecia areata, telogen effluvium, traumatic alopecia, trichotillomania alopecia, compression alopecia, anagen alopecia, pityriasis alopecia, syphilitic alopecia, seborrheic alopecia, symptomatic alopecia, non-scarring alopecia, scarring alopecia, congenital alopecia, and combinations thereof.
[0085] In particular, the Cornarus conchocapis extract of the present invention can effectively suppress the progression of hormonal alopecia such as androgenetic alopecia through inhibition of 5-α-reductase and androgen receptor expression, and can also have a significant effect on autoimmune alopecia such as alopecia areata through inhibition of the JAK pathway. In addition, activation of the Wnt / β-catenin pathway can contribute to the recovery of telogen effluvium or seborrheic or inflammatory alopecia through induction of regeneration and growth phase of hair follicle cells.
[0086] Therefore, the extract of the present invention can be widely applied to alopecia caused by various etiologies, and can be utilized as a natural therapeutic material that shows excellent efficacy, especially in types of hair loss involving hormonal, autoimmune, and inflammatory mechanisms.
[0087] In one aspect of the present invention, the present invention provides a pharmaceutical composition or use for preparing a medicament comprising a Connarus conchocarpus extract for the prevention or treatment of alopecia. Since the use has in common with the pharmaceutical composition in that it comprises a Connarus conchocarpus extract, description of the common portions is omitted to avoid excessive redundancy.
[0088] In one aspect of the present invention, there is provided a method for preventing or treating alopecia, comprising administering to a subject a pharmaceutical composition comprising a Connarus conchocarpus extract. Since the method for preventing or treating alopecia shares similarity with the pharmaceutical composition in that it comprises a Connarus conchocarpus extract, description of the common portions is omitted to avoid excessive duplication.
[0089]
[0090] In one aspect of the present invention, the present invention provides a method for preparing a Connarus conchocarpus extract, comprising the step of extracting Connarus conchocarpus by adding a solvent selected from the group consisting of a glycol solvent, water, alcohol, or a combination thereof.
[0091] The method for producing the Cornarus conchocapis extract of the present invention has something in common in that it obtains the Cornarus conchocapis extract described above, and therefore, it is common in the pretreatment or state of Cornarus conchocapis, the type, amount or concentration of the solvent, extraction conditions such as extraction time or temperature, extraction method, etc., and in order to prevent excessive redundant description in the specification, the description of the common parts is omitted.
[0092] In one embodiment of the present invention, the glycol solvent has a concentration of 20% (v / v) to 80% (v / v); or the alcohol has a concentration of 20% (v / v) to 80% (v / v).
[0093] In one embodiment of the present invention, the manufacturing method includes a step of hot water extraction of the residue remaining after the glycol solvent extraction step at a concentration of 20% (v / v) to 80% (v / v).
[0094] In one aspect of the present invention, a Cornarus conchocapis extract can be prepared through a two-step sequential extraction process. In particular, by additionally performing hot water extraction on the plant residue remaining after the first extraction step using a glycol solvent, the effective ingredients contained in Cornarus conchocapis can be more comprehensively secured.
[0095] More specifically, first, a 20% (v / v) to 80% (v / v) glycol solvent, such as butylene glycol, propylene glycol, etc., diluted in purified water is used to perform immersion or stirring extraction on the dried powder of Cornarus conchocapis. The extraction can be performed at a temperature of 25 to 60°C for 10 to 100 hours, and then the glycol solvent extract is separated through filtration.
[0096] The solid residue remaining after the above filtration may contain water-soluble physiologically active substances (e.g., polysaccharides, phenols, water-soluble flavonoids, etc.) that were not recovered in the first extraction. Therefore, by performing a second hot water extraction on this residue, a complex extract containing a wider variety of components can be obtained.
[0097] Secondary extraction is performed by adding purified water to the residue in an amount 10 to 20 times the weight of the residue, followed by heating, stirring, or immersion extraction at a temperature of approximately 100°C for 2 to 5 hours or more. The final hot water extract is then obtained through filtration and reduced pressure concentration. This hot water extract can be combined with the primary glycol solvent extract, fractionated separately, or used as a complementary agent within the composition.
[0098] In this way, the extraction method of the present invention has the advantage of being able to more quantitatively and efficiently secure polar and water-soluble active ingredients present in the Cornarus conchocapis plant compared to a single solvent extraction method, and by expanding the spectrum of physiologically active ingredients through two-step extraction, the hair loss inhibition and hair growth promotion effects of the final composition can also be improved.
[0099] In one embodiment of the present invention, the manufacturing method additionally includes a reduced pressure concentration step performed after extraction.
[0100] In the above manufacturing method, a vacuum concentration step can be added after the extraction process to remove the solvent and increase the concentration of the active ingredient. Vacuum concentration is typically performed using a rotary evaporator or vacuum concentrator, evaporating the solvent under low pressure at a temperature of 40 to 60°C to concentrate the extract. This process has the advantage of increasing concentration efficiency while minimizing the decomposition of heat-sensitive active ingredients, ultimately securing a high-concentration extract in a form suitable for composition manufacturing.

[0142]
[0143] Example
[0144] Example 1: Preparation of Connarus conchocarpus extract
[0145] 1-1. Preparation of Connarus conchocarpus butylene glycol extract
[0146] Butylene glycol (BG) was mixed with purified water to prepare 30% (v / v), 50% (v / v), and 70% (v / v) aqueous solutions of butylene glycol, each prepared by mixing BG with purified water, and added 10 times the weight of BG to 200 g of dried Connarus conchocarpus, followed by extraction at 25°C for 3 days. Each extract was concentrated in a vacuum evaporator to obtain more than 10 g of Connarus conchocarpus extract. These were designated CC-BG30, CC-BG50, and CC-BG70.
[0147]
[0148] 1-2. Preparation of Connarus conchocarpus hot water extract
[0149] After the first extraction with 30% (v / v), 50% (v / v), and 70% (v / v) butylene glycol aqueous solutions, purified water was added 15 times to each remaining residue, extracted at 100°C for 4 hours, and each extract was concentrated in a vacuum evaporator to obtain more than 10 g of Connarus conchocarpus extract, respectively. These were named CC-W30, CC-W50, and CC-W70.

[0156] Example 2: Evaluation of Janus kinase (JAK) 1 inhibition ability In order to evaluate the JAK1 (Janus kinase 1) inhibition ability, a major biomarker of alopecia areata, of each sample prepared in Example 1, an experiment was performed using HEK293T cells with high transfection efficiency. JAK1 overexpression conditions were established by transfecting HEK293T cells with FLAG-tagged JAK1 (FALG-JAK1), and 500 μL of each test sample was treated according to the concentration.
[0157] After sample treatment, cells were harvested in 1 mL of phosphate-buffered saline (PBS), transferred to a microtube (e-tube), and centrifuged at 12,000 rpm for 3 minutes to remove the supernatant, leaving only the pellet. Subsequently, a lysis buffer containing the following components was used to lyse the cells: 50 mM Tris-HCl (pH 7.4), 120 mM NaCl, 25 mM β-glycerol phosphate (pH 7.5), 20 mM sodium fluoride (NaF), 2% NP-40 (Nonidet P-40), and protease inhibitors.
[0158] After dissolution, sonication was performed, and then the supernatant was obtained by re-centrifugation at 12,000 rpm at 4°C for 3 minutes. The obtained supernatant was separated through 10-15% concentration SDS-polyacrylamide gel electrophoresis (SDS-PAGE), and Western blotting analysis was performed using each antibody for p-JAK1, JAK1, p-STAT3, STAT3, and β-actin.
[0159] The results are shown in Figure 1.
[0160] As shown in Fig. 1, in the FLAG-JAK1 transfection group, the band intensities of FLAG and JAK1 proteins were confirmed to increase compared to the control group (Normal). As a result of comparing the JAK1 inhibitory effect of each extract, the 50% ethanol extract (sample 8, CC-EE30) showed the best inhibitory activity, and the 30% and 70% ethanol extracts (sample 7, CC-EE30; sample 9, CC-EE70) also showed a significant decrease in JAK1 phosphorylation. In addition, the 70% butylene glycol extract (sample 3, CC-BG70) and the hot water extract (sample 6, CC-W70) were also confirmed to show a certain level of inhibitory effect.
[0161] These results suggest that Connarus conchocarpus ethanol extract is a natural material with significant inhibitory activity against JAK1, a major target of alopecia areata.
[0162]
[0163] Example 3: Evaluation of 5-α-reductase inhibition ability
[0164] 5-alpha-reductase, a key target of male pattern baldness, converts the male hormone testosterone into dihydrotestosterone (DHT). Increased expression of this enzyme leads to increased DHT production, and DHT is known to induce androgen receptor (AR) activity more strongly than testosterone, promoting hair follicle shrinkage and hair loss.
[0165] The 5-α-reductase inhibitory activity of the Connarus conchocarpus extract prepared in Example 1 was evaluated. 10-week-old male Sprague-Dawley rats were used for the experiment, and the entire liver of the rat was extracted, homogenized with a lysis buffer containing the following composition, and the enzyme was extracted: 7.5 nM K2HPO₄, 3.25 nM KH₂PO₄, 1 mM dithiothreitol (DTT), 32 mM sucrose, 0.2 mM phenylmethylsulfonyl fluoride (PMSF), and additional protease inhibitors.
[0166] For 4 μL of the extracted enzyme, 34 mM NADPH (nicotinamide adenine dinucleotide phosphate) and 0.4 mM testosterone were added to the reaction system in which the sample to be evaluated was treated at a concentration of 20 μM, and then McIlvaine buffer (pH 5.0) was immediately added. The reaction was terminated by heat treatment at 80°C for 5 minutes, and the oxidation of NADPH was measured as a change in absorbance at a wavelength of 340 nm to evaluate the change in enzyme activity.
[0167] The results are shown in Fig. 2.
[0168] As shown in Fig. 2, butylene glycol (BG) extract and hot water extract showed no inhibitory effect or rather a tendency to increase enzyme activity, whereas ethanol extracts (CC-EE30, sample 7; CC-EE50, sample 8; CC-EE70, sample 9) all showed excellent inhibitory activity. In particular, the 30% ethanol extract (CC-EE30, sample 7) showed higher inhibitory activity than the positive control, finasteride, and the 50% and 70% ethanol extracts (CC-EE50, sample 8; CC-EE70, sample 9) also showed strong inhibitory effects.
[0169] In summary, these results show that the ethanol extract among Connarus conchocarpus extracts effectively inhibits 5-α-reductase activity, and in particular, the 30% and 50% ethanol extracts (CC-EE30, sample 7; CC-EE50, sample 8) showed excellent inhibitory effects on the main causative mechanism of male pattern baldness. In addition, the ethanol extract also consistently exhibited the previously confirmed JAK1 inhibitory effect, suggesting that it has dual efficacy that can be simultaneously applied to alopecia areata. On the other hand, the butylene glycol extract and the hot water extract showed limited effects only on specific targets.
[0170]
[0171] Example 4: Evaluation of androgen receptor (AR) production inhibition ability
[0172] Male pattern baldness is caused by increased blood dihydrotestosterone (DHT) concentrations, which promote the expression of androgen receptors (ARs), ultimately leading to hair follicle shrinkage and hair loss. This is one of the major pathological mechanisms underlying hair loss. Therefore, the Connarus conchocarpus extracts prepared in Example 1 were evaluated for their ability to inhibit androgen receptor production.
[0173] In this experiment, HEK293T cells, which have high transfection efficiency, were used and transfected with the Myc-DDK-SRD5A2 plasmid to establish an androgen receptor overexpression model. The cells were then treated with testosterone to create conditions for androgen receptor overexpression, and 500 μL of each test sample was administered.
[0174] Cells were washed with 1 mL of phosphate-buffered saline (PBS), transferred to an e-tube, and centrifuged at 12,000 rpm for 3 minutes to remove the supernatant, leaving only the pellet. Cells were then lysed using a lysis buffer composed of the following composition: 50 mM Tris-HCl (pH 7.4), 120 mM NaCl, 25 mM β-glycerol phosphate (pH 7.5), 20 mM NaF (sodium fluoride), 2% NP-40 (Nonidet P-40), and protease inhibitors.
[0175] After dissolution, sonication was performed, and the supernatant was obtained by centrifugation at 12,000 rpm for 3 minutes at 4°C. The obtained sample was subjected to 10-15% SDS-polyacrylamide gel electrophoresis (SDS-PAGE) to separate proteins, and Western blot analysis was performed using antibodies against Myc, androgen receptor (AR), and β-actin.
[0176] The results are shown in Fig. 3.
[0177] As shown in Fig. 3, among the nine samples, the 30% butylene glycol extract (CC-BG30, sample 1), the hot water extract (CC-W50, sample 5), and the 50% ethanol extract (CC-EE50, sample 8) showed excellent inhibitory activity against androgen receptor production, and exhibited even stronger inhibitory activity than dutasteride, which was used as a positive control. In addition, CC-BG50 (sample 2), CC-W70 (sample 6), and CC-EE30 (sample 7) also showed a certain level of inhibitory activity.
[0178] These results suggest that extracts derived from Connarus conchocarpus have physiological activity that can effectively inhibit DHT-induced androgen receptor expression, and in particular, it was confirmed that not only ethanol extracts but also some BG and water extracts can act target-specifically.
[0179]
[0180] Example 5. Evaluation of the effect of activating the Wnt / β-Catenin signaling pathway.
[0181] During the progression of male pattern baldness, increased dihydrotestosterone (DHT) concentrations promote androgen receptor (AR) expression, thereby inhibiting the Wnt / β-Catenin signaling pathway, thereby interfering with hair follicle anagen induction and inducing hair loss. Therefore, in this example, we evaluated whether Connarus conchocarpus extract could activate the Wnt / β-Catenin signaling pathway.
[0182] The experiment was conducted using HEK293T cells with high transfection efficiency. After establishing experimental conditions by transfecting HEK293T cells with the SRD5A1-GFP plasmid, 500 μL of each sample prepared in Example 1 was treated according to the concentration.
[0183] Cells were washed with 1 mL of phosphate-buffered saline (PBS), transferred to an e-tube, and centrifuged at 12,000 rpm for 3 minutes to remove the supernatant, leaving only the pellet. Cells were then lysed using a lysis buffer containing the following components: 50 mM Tris-HCl (pH 7.4), 120 mM NaCl, 25 mM β-glycerol phosphate (pH 7.5), 20 mM NaF (sodium fluoride), 2% NP-40 (Nonidet P-40), and protease inhibitors.
[0184] After dissolution, sonication was performed, and the supernatant was obtained by centrifugation at 12,000 rpm for 3 minutes at 4°C. The obtained proteins were separated through 10-15% SDS-polyacrylamide gel electrophoresis (SDS-PAGE), and Western blot analysis was performed using each antibody against GFP, Wnt3a, β-catenin, and β-actin.
[0185] The results are shown in Fig. 4.
[0186] As shown in Fig. 4, among the samples with increased expression of Wnt3a and β-catenin, the 50% ethanol extract (CC-EE50, sample 8) showed the most excellent activation effect, and the 4th and 6th water extracts (CC-W30, sample 4; CC-W70, sample 6) also showed excellent Wnt3a expression induction effects. In addition, the 50% and 70% butylene glycol extracts (CC-W50, sample 5; CC-W70, sample 6) were also observed to have the effect of inducing a certain level of signal pathway activation.
[0187] According to the results of the above examples, when ethanol was used as a solvent in the preparation of Connarus conchocarpus extract, it exhibited various physiological activities, and in particular, 30% and 50% ethanol extracts (CC-EE30, sample 7; CC-EE50, sample 8) showed excellent inhibitory effects on major biomarkers related to hair loss. On the other hand, in the evaluation of Wnt3a and β-catenin expression, not only the 50% ethanol extract (CC-EE50, sample 8) but also the hot water extracts (CC-W30, sample 4; CC-W70, sample 6) showed excellent expression induction effects, confirming that the hot water extract is also effective in promoting hair growth.
[0188] Therefore, these results confirmed that Connarus conchocarpus extracts, especially the 30% or 50% ethanol extracts (CC-EE30, sample 7; CC-EE50, sample 8) and the hot water extracts prepared from the residue after 30% or 70% butylene glycol extraction (CC-W30, sample 4; CC-W70, sample 6), activated the Wnt / β-Catenin pathway. Meanwhile, Wnt signaling activity is known to be closely related to the proliferation of dermal papilla cells. The Wnt / β-catenin signaling pathway regulates the survival and proliferation of dermal papilla cells and plays an important role in the hair growth cycle. When Wnt signaling is activated, β-catenin is not degraded in the cytoplasm but translocates to the nucleus, inducing the expression of genes that promote cell proliferation and differentiation. Therefore, it is suggested that the Cornarus conchocapis extract of the present invention can effectively act to promote hair follicle growth and induce hair growth by activating the Wnt / β-catenin pathway to increase the proliferation of hair papilla cells and promote hair growth.
