Background Art
[0003] Most mammals are covered with hair. Hair loss, also known as alopecia or baldness, is a condition that involves the complete or partial loss of hair growth and affects a significant portion of the population. Hair loss may be desirable for some people, while it can be a concern for those who wish to maintain a younger appearance. The treatments currently used for baldness have had little success and cause significant side effects to patients, including anti-androgen related toxicity or inflammation of the skin.

[0032] [Figure 1] (Figures 1A-1D) Topical application of SADBE and DPCP demonstrates induction of the growth phase and hair growth in mice. Figure 1A shows the molecular structures of SADBE and DPCP. Both are contact sensitizers (haptens). Figure 1B is a schematic diagram showing the schedule for topical administration of haptens to the skin of mice in which hair follicles have been arrested in the resting phase. Figure 1C is a collection of photographs of mice treated topically with haptens. Red circles indicate that the treated flanks demonstrate the growth phase and hair growth. Green circles indicate that the untreated flanks demonstrate the resting phase. Treatment with contact sensitizers often results in skin inflammation (red "*"). Figure 1D is a graph showing relative induction of the growth phase, measured by enhanced skin pigmentation intensity (a marker of the growth phase) on the treated side as a percentage of the untreated side (relative to) the baseline. [Figure 2] (Figures 2A-2C) Novel compounds that induce the growth phase and hair growth are shown. Figure 2A shows the molecular structures of synthesized SADBE derivatives that showed improved growth phase induction and / or reduced inflammation. Figure 2B shows images of mice administered with SADBE, CF3-SADBE, and CCl-SADBE. CF3-SADBE appeared to induce the growth phase and hair growth at least as efficiently as SADBE, which caused less inflammation. CCl-SADBE did not produce either inflammation or growth phase and hair growth. Red circles indicate treated flanks demonstrating the growth phase and hair growth. Green circles indicate untreated flanks demonstrating the resting phase. Red circles indicated by dotted lines show flanks treated with CCl-SADBE with hair remaining in the resting phase. (Red "*") indicates inflammation in flanks treated with SADBE. Figure 2C is a graph showing the relative growth-stage induction for SADBE and its derivatives. [Figure 3](Figures 3A-3B) CF3-SADBE efficiently induces the growth phase and hair growth with less inflammation than SADBE. Figure 3A shows that treatment with 100 mM SADBE induces the growth phase with substantial inflammation by day 14 (blue "*", blue circle), while the same amount of CF3-SADBE induces the growth phase with very little visible inflammation (red circle). Healthy hair growth is observed in the treated flanks by day 17. Figure 3B is a graph showing the relative induction of the growth phase as the percentage of the untreated side compared to the baseline, measured over time for both treatments. [Figure 4] (Figures 4A-4C) These images show that CF3-SADBE treatment induces telogenous hair follicles to enter the anagen phase. Figure 4A shows the macroscopic appearance of a mouse with the left flank treated with 100 mM CF3-SADBE and the right flank untreated. Figure 4B shows skin treated with CF3-SADBE stained with hematoxylin and eosin (H&E) (red "*"), indicating anagen hair follicles, and Figure 4C shows hair follicles in untreated skin remaining in the telogen phase (green "*"). [Figure 5] This image shows the growth phase and hair growth induced by CF3-SADBE, which is earlier and causes less inflammation than SADBE. Treatment with CF3-SADBE causes a clear growth phase by day 10, while SADBE does not (purple arrows). SADBE also causes more pronounced inflammation by day 14 (blue asterisks). Healthy hair growth is observed on the treated flank by day 17. [Modes for carrying out the invention]
[0033] Compositions for treating hair loss are not well developed, and currently available treatments involve the administration of compounds that have had little success and cause discomfort to patients.
[0034] hair growth composition As described herein, we have developed numerous hapten derivative compounds. These compounds enhance or stimulate hair growth. Some compounds enhance hair growth while minimizing skin inflammation. We synthesized the compound of formula (1):
[0035] [ka]
[0036] Subsequently, topical delivery of the compound, overall after prior shaving, resulted in accelerated hair growth in mice compared to the treated contralateral skin of the vehicle control. In some cases, topical delivery of the novel compound (e.g., CF3-SADBE) also showed less inflammation than known treatments. Furthermore, CF3-SADBE also appeared to exhibit an enhanced effect, such as that measured by the early induction of the growth phase at the time of topical delivery.
[0037] An unspecified list of useful hapten derivatives developed herein includes the following compounds:
[0038] [Table 1]
[0039] To improve the therapeutic activity and safety of topical hair growth agents, we designed this hapten derivative compound. In an attempt to improve solubility and potential skin penetration properties, we replaced the dibutyl ester moiety by introducing PEG or saturated alkyl long chains. However, neither compound was active in promoting hair growth in animal models.
[0040] Subsequently, shorter alkyl chains were introduced. CF3 or CL-substituted alkyl chains were designed. It was hypothesized that both compounds might have similar crosslinking reactivity. Surprisingly, the CF3-substituted compounds were active in promoting hair growth, while the CL-substituted compounds showed low activity. This indicated that hair growth promoting activity is not simply related to the reactivity of the compound as a crosslinking agent.
[0041] CF3 compounds (e.g., CF3-SADBE or MGH-CS-4 mentioned above) showed accelerated hair growth and seemingly slightly reduced inflammation compared to known treatments.
[0042] Synthesis of CF3-SADBE
[0043] [ka]
[0044] A solution of square acid (9 mmol) and alcohol (36 mmol) in toluene (9 ml) was refluxed at 100°C for 16 hours using a Dean-Stark apparatus. After the reaction was complete, the toluene was concentrated under vacuum, and the resulting solution was diluted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate solution, and then with brine. The volatile components were concentrated under vacuum, and the compounds were purified by column chromatography to obtain each compound.
[0045] Use of compositions to stimulate hair growth The compounds described herein can be used in compositions for treating hair loss, promoting hair growth, reducing hair loss, stimulating hair growth, thickening hair, or reducing thinning hair. Hair loss can be caused by a variety of conditions. Some of these conditions are related to autoimmune diseases, while some are not related to autoimmunity.
[0046] Use of CF3-SADBE and other novel compounds to promote hair growth As described herein, CF3-SADBE can be used in the treatment of hair loss and / or to promote hair growth in subjects requiring such treatment. CF3-SADBE can be useful in the treatment of alopecia associated with autoimmune diseases (e.g., alopecia areata) or alopecia not associated with autoimmune diseases. An unspecified list of alopecia conditions (autoimmune-related alopecia and non-autoimmune alopecia) includes: acne keloids (e.g., keloid folliculitis, nape acne keloids), alopecia areata (autoimmune alopecia; e.g., serpentine alopecia), complete alopecia, generalized alopecia, anagenous alopecia, androgenous alopecia (e.g., male and female pattern hair loss), block alopecia, central centrifugal scarring alopecia, scarring alopecia (e.g., primary scarring alopecia), congenital alopecia, congenital hypotrichosis, diffuse alopecia areata, discoid (lesional) lupus erythematous (DLE), dissociative cellulitis (e.g., perifolliculitis, abscessive perifolliculitis) Folliculitis), "terminal" or "untreatable" scarring alopecia, female pattern hair loss, alopecia folliculitis, frontal sclerosing alopecia, hair shaft abnormalities, hyperandrogenicity, hypotrichosis, hereditary alopecia, lichen planus, keratosis pilaris (e.g., diffuse), lipoderma alopecia (lipoderma scalp), male pattern hair loss (e.g., bilateral skull), non-scarring alopecia, psoriasis, psoriasis-like alopecia, compression (postoperative) alopecia, seborrheic dermatitis psoriasis, telogen effluvium, temporal triangle alopecia, tinea capitis, TNF-α inhibitor-induced psoriasis-like alopecia, traction alopecia, trichorrhizosis nodosa, trichotillomania, and tufted folliculitis (e.g., Bolognia, et. al., Dermatology. Elsevier Health Sciences, June 8, 2012. Pages 1163-1187. Section 11: Hair, Nails, and Mucous Membranes. 69: Alopecias).Methods for diagnosing these conditions or identifying subjects with these conditions are publicly known in the art, see, for example, Bolognia, et. al., Dermatology. Elsevier Health Sciences, June 8, 2012. Pages 1163-1187. Section 11: Hair, Nails, and Mucous Membranes. 69: Alopecias.
[0047] Use of SADBE or DPCP for the treatment of alopecia beyond autoimmune alopecia. Surprisingly, as described herein, the compounds SADBE and DPCP can also be used to treat alopecia not associated with autoimmune diseases (e.g., for the treatment of alopecia conditions other than alopecia areata). SADBE and DPCP have been used to treat alopecia areata, autoimmune-associated alopecia. However, prior to this disclosure, it was not known that DPCP and / or SADBE could enhance hair growth in mammals without autoimmune diseases. As shown herein, SADBE enhanced (e.g., accelerated) hair growth in mammals without autoimmune diseases. DPCP also showed enhanced hair growth in mammals without autoimmune diseases.
[0048] An unspecified list of non-autoimmune-related alopecia includes: acne keloids (e.g., keloid folliculitis, nape acne keloids), complete alopecia, generalized alopecia, pubertal alopecia, androgen-induced alopecia (e.g., male and female pattern hair loss), nerve block alopecia, central centrifugal scarring alopecia, scarring alopecia (e.g., primary scarring alopecia), congenital alopecia, congenital malformation, diffuse alopecia areata, discoid (lesional) lupus erythematous (DLE), dissociative cellulitis (e.g., perifollicular inflammation, abscessive puncture folliculitis), "terminal" or "drug-induced" Examples of conditions for which treatment is ineffective include scarring alopecia, female pattern hair loss, alopecia folliculitis, frontal sclerosing alopecia, hair shaft abnormalities, hyperandrogenicity, hypotrichosis, hereditary alopecia, lichen planus, keratosis pilaris (e.g., diffuse), lipoderma alopecia (lipoderma scalp), male pattern baldness (e.g., bilateral skull), non-scarring alopecia, psoriasis, psoriasis-like alopecia, pressure (postoperative) alopecia, seborrheic dermatitis psoriasis, telogen effluvium, temporal triangle alopecia, tinea capitis, TNF-α inhibitor-induced psoriasis-like alopecia, traction alopecia, trichorrhizosis nodosa, trichotillomania, and tufted folliculitis. Methods for diagnosing these conditions or identifying subjects with these conditions are publicly known in the art, see, for example, Bolognia, et. al., Dermatology. Elsevier Health Sciences, June 8, 2012. Pages 1163-1187. Section 11: Hair, Nails, and Mucous Membranes. 69: Alopecias.
[0049] Combination therapy In some embodiments, the methods described herein may include administering combination therapy. A non-limiting list of therapeutic options that can be administered by the compositions and methods described herein includes: topical corticosteroids, oral corticosteroids, and intralesional corticosteroids (e.g., clobetasol, fluocinonide), topical stimulants (e.g., anthraline, tazarotene, azelaic acid), topical minoxidil, topical finasteride, dutasteride, topical immunotherapy, systemic corticosteroids (e.g., pulsed administration), oral finasteride (e.g., type II 5α-reductase inhibitors), and Examples include oral tetracyclines (e.g., doxycycline, minocycline), oral rifampin and clindamycin, TNF-α inhibitors, PPAR-γ agonists (e.g., pioglitazone hydrochloride), isotretinoin, oral zinc sulfate, oral antimalarial drugs (e.g., hydroxychloroquine), systemic JAK / STAT pathway inhibitors (e.g., tofacitinib or ruxolitinib), topical or oral photochemotherapy, excimer lasers, systemic corticosteroids (e.g., chronic), and systemic cyclosporine.
[0050] Administration of formulations and compositions The disclosed compositions can be used in a variety of ways. For example, they may be components of dry formulations or wet solutions. They may be provided as components of injectable compositions that are injected (e.g., intradermally or subcutaneously) into bald areas (e.g., scalp). Alternatively, the compounds described herein may be components of compositions that are applied topically to bald or hair loss areas. This can be done for the purpose of densening the appearance of hair. These compositions may be optionally applied in combination with any known non-toxic delivery and / or penetration agents.
[0051] The disclosed compositions may be administered topically or by infusion. The required dose depends on the choice of route of administration; the nature of the formulation; the nature of the condition of the subject; the size of the subject, the surface area of treatment, age, and sex; other medications administered; and the judgment of the attending physician. In some embodiments, the appropriate dose is in the range of 0.01 to 500.0 mg / kg. The various doses required are expected to take into account the different efficiencies of various routes of administration. These dose level variations may be adjusted by standard empirical practices for optimization, as is well understood in the art. Administration may be a single dose or multiple doses (e.g., 2, 3, 4, 6, 8, 10, 20, 50, 100, 150, or more multiples). The disclosed compositions may also be administered in a single topical treatment. The disclosed compositions may also be administered in multiple topical treatments. Multiple doses may be daily, every other day, twice a week, weekly, bi-weekly, monthly, or any combination thereof. The compositions described herein may be administered daily, weekly, monthly, yearly, or for longer periods. Encapsulation of the compounds into a suitable delivery vehicle (e.g., cream, emulsion, aqueous solution, or solid) may enhance the efficiency of delivery. The required dosage also depends on skin variability. Dose differences may be necessary due to different skin thickness at the hair-supporting sites, number of applications, skin type, different symptoms (e.g., different causes of alopecia), and / or different tolerances depending on the subject.
[0052] The compositions of this application can be prepared for storage by mixing them with one or more of the various pharmaceutically acceptable carriers, additives, or stabilizers known in the art. Acceptable carriers, additives, or stabilizers are nontoxic to the recipient at the dose and concentration used and include: buffers such as phosphates, citrates, and other non-toxic organic acids; antioxidants such as ascorbic acid; low molecular weight (less than 10 residues) polypeptides; proteins such as serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as polyvinylpyrrolidone; amino acids such as glycine, glutamine, asparagine, arginine, or lysine; monosaccharides, disaccharides, and other carbohydrates including glucose, mannose, or dextran; chelating agents such as EDTA; sugar alcohols such as mannitol or sorbitol; salt-forming counterions such as sodium; and / or nonionic surfactants such as Tween, Pluronic, or PEG.
[0053] The composition may be in any form suitable for application to the scalp and / or hair, such as a solution, suspension, lotion, cream, gel, cosmetic liquid, stick, pencil, spray, aerosol, ointment, liquid cleanser and solid bar, shampoo and hair conditioner, paste, foam, milk, pup, water-oil two-layer composition, water-oil-powder three-layer composition, serum, powder, mousse, shaving cream, wipe, strip, patch, hydrogel, film-forming product, disposable applicator, etc. The composition may be a shampoo, hair conditioner, or hair lotion. The form of the composition may be obtained from a selected specific dermatologically acceptable carrier, if present in the composition. The composition may be in the form of an aqueous, aqueous-alcohol, or oily solution, lotion or serum-type dispersion, or emulsion (e.g., a milk-type emulsion of liquid or semi-liquid consistency). The composition may be in the form of an aqueous or anhydrous cream or gel-type suspension or emulsion, or microcapsules or particles, or ionic and / or nonionic vesicle dispersions. The composition may be anhydrous or aqueous.
[0054] The compositions described herein may include a dermatologically acceptable carrier (also referred to herein simply as “carrier”). The expression “dermatologically acceptable carrier” means, as used herein, that the carrier is suitable for topical application to hair / scalp, has good aesthetic properties, is miscible with the hair anti-aging agents in the composition, and does not cause inappropriate safety or toxicity concerns. An appropriate carrier is selected to obtain the desired product form. Furthermore, the solubility or dispersibility of the components may affect the form and characteristics of the carrier. In some embodiments, the carrier is present at levels of about 50% to about 99% by weight, about 60% to about 98% by weight, about 70% to about 98% by weight, or or about 80% to about 95% by weight of the composition.
[0055] The carrier can take on a variety of forms. Examples, though not limited to them, include simple solutions (e.g., aqueous, organic solvent, or oily), emulsions, and solid forms (e.g., gels, sticks, fluid solids, or amorphous materials). In some embodiments, the dermatologically acceptable carrier is in the form of an emulsion. Emulsions can generally be classified into those having a continuous aqueous phase (e.g., oil-in-water and water-in-oil in-water) or a continuous oil phase (e.g., water-in-oil and oil-in-water in oil). The oil phase of this disclosure may include silicone oils, hydrocarbon oils, non-silicone oils such as esters and ethers, and mixtures thereof.
[0056] The aqueous phase includes water, such as demineralized water or distilled water. Other acceptable carriers that may be used in the aqueous carrier include, but are not limited to, alcohol compounds such as ethanol. According to one embodiment, the composition comprises alcohol, dipropylene glycol, and / or water.
[0057] The composition has a pH in the range of about 3.0 to about 10 (for example, about pH 4.0 to about pH 9.0, about pH 5.0 to about pH 9.0, or about pH 6.0 to about pH 8.0) and can be measured by direct pH measurement using a standard hydrogen electrode of the composition at 25°C. Therefore, the pH of the composition may be in the range of, for example, about 6 to about 9.
[0058] The emulsion may further contain an emulsifier. The composition may contain any suitable proportion of emulsifier to adequately emulsify the carrier. Suitable weight ranges include emulsifiers of about 0.1% to about 10% or about 0.2% to about 5% relative to the weight of the composition. The emulsifier may be nonionic, anionic, or cationic. Suitable emulsifiers are disclosed, for example, in U.S. Patent Nos. 3,755,560 and 4,421,769, and McCutcheon's Detergents and Emulsifiers, North American Edition, pages 317-324 (1986), the entirety of which is incorporated herein by reference. Suitable emulsions may have a wide range of viscosities depending on the desired product form. Examples of emulsifiers, though not limited to them, include glyceryl stearate, polysorbate 60, and the PEG-6 / PEG-32 / glycerol stearate mixture sold by Gattefosse under the name Trefose®. The emulsion may contain a fatty phase that may amount to about 5% to about 80% by weight (e.g., about 5% to about 50% by weight) of the composition. Any of the emulsions described herein may contain one or more agents selected from the group of oils, waxes, emulsifiers, and co-emulsifiers. Examples of oils, waxes, emulsifiers, and co-emulsifiers used in hair care compositions are well known in the art.

[Examples]
[0066] The compositions and methods of this disclosure are further described in the following examples and do not limit the scope of the disclosure set forth in the claims.
[0067] [Example 1] Topical administration of SADBE and DPCP To measure the effects of SABDE and DPCP (see Figure 1a) on hair growth, both flanks of six 8-week-old female C57BL / 6 mice were shaved four days prior to topical administration of the compounds (-4 days). During this period, the mice were visually monitored to confirm the absence of hair growth and that the entire shaved area was in the telogen phase, as expected from 8-week-old mice. On the day of administration (day 0), 2% SABDE or 2% DCPC was administered topically to the shaved left flank of each of the three mice using a cotton swab (see Figure 1b). Images were taken on days 9 and 16 to visualize hair growth and inflammation (see Figure 1c). Skin pigmentation intensity was quantified using ImageJ. The growth-inducing index was calculated as the change in skin pigmentation intensity (a marker of the growth phase) on the treated side compared to the untreated side (i.e., as a percentage) (see Figure 1d).
[0068] The growth-inducing index can be determined by any method known in the art, including, for example, histological methods (e.g., H&E, with or without staining) and / or other visual morphological methods (e.g., methods for measuring the biological parameters of hair growth). This value is then standardized for a specific experiment (individual mice) and expressed as relative growth induction by the intensity of skin pigmentation on the treated side (a marker of growth) as a percentage of the reference value to the untreated side. Analysis of the growth phase (or other stages) can be carried out by any method known in the art, including, for example, tissue biopsy and / or morphological analysis.
[0069] Inflammation can be measured by known methods such as histological grading, visual identification, and quantification of lesions. Present skin lesions (e.g., blue in Figure 3a) * The number, size, and extent of the references can be visualized and quantified using any method known in the art, including, for example, histological methods (e.g., H&E, other staining or no staining) and / or other visual morphological methods.
[0070] [Example 2] Local administration of novel compounds To compare the effects of SABDE, CF3-SABDE, or CCl-SABDE (see Figure 2a) on hair growth, the chests of three 8-week-old female C57BL / 6 mice were pre-sensitized with 2% of each compound four days before the first treatment, and both flanks were shaved (Day 0). On days 3, 5, and 7, 2% of SABDE, CF3-SABDE, or CCl-SABDE was administered topically to the shaved left flank of each mouse using a cotton swab. Images were taken on day 17 to visualize hair growth and inflammation (see Figures 2B and 2C).
[0071] [Example 3] Comparison of known and novel compounds The effects of local therapeutic doses of SADBE or CF3-SADBE were measured using the method described in Example 1. In Figure 3, the local therapeutic dose used was 50 μL of 100 mM SADBE or CF3-SADBE.
[0072] [Example 4] Induction of growth phase by CF3-SADBE The effects of local therapeutic doses of CF3-SADBE were measured and visualized using the method described in Example 1. Macroscopic images of mice treated with CF3-SADBE were obtained (see Figure 4a). CF3-SADBE was administered to the left flank at a dose of 100 μL of 100 mM CF3-SADBE (see Figure 4B). The right flank remained untreated (see Figure 4C).
[0073] [Example 5] Early growth induction with CF3-SADBE, which causes less inflammation than SADBE. The effects of topical treatment with 100 mM CF3-SADBE on growth spurt induction and inflammation were measured and visualized using the method described in Example 1. Treatment with 100 mM CF3-SADBE induced a clear growth spurt by day 10. Treatment with 100 mM SADBE did not induce a clear growth spurt by day 10 (see purple arrow in Figure 5). This indicates the improved efficacy of CF3-SADBE. SADBE also caused more pronounced inflammation by day 14 (see blue arrow in Figure 5). * (See reference). Healthy hair growth was observed on the treated flank by day 17. Other Embodiments
