인돌린-2-티온 유사체를 함유한 미백용 조성물{COMPOSITION FOR WHITENING OF THE SKIN COMPRISING INDOLINE-2-THIONES DERIVATIVES}Whitening composition containing indolin-2-thione analogues {COMPOSITION FOR WHITENING OF THE SKIN COMPRISING INDOLINE-2-THIONES DERIVATIVES}

본 발명은 인돌린-2-티온 유사체의 미백용도와 인돌린-2-티온 유사체를 유효 성분으로 하는 미백용 조성물에 관한 것이다. The present invention relates to a whitening composition of an indolin-2-thione analog and an whitening composition comprising an indolin-2-thione analog as an active ingredient.

사람의 피부색은 멜라닌, 카로틴, 헤모글로빈의 양에 따라 결정되며, 그 중 멜라닌이 가장 결정적인 요소로 작용한다. 멜라닌 색소는 검은 색소와 단백질의 복합체 형태를 갖는 페놀계 고분자 물질로서 자외선 차단 역할을 하여, 멜라닌 색소가 부족한 사람은 햇빛에 매우 민감하여 화상을 입기 쉬우며 어린 나이에도 피부암의 발생 확률이 높다. 한편, 단파장의 자외선 및 발암물질은 피부에서 유해한 자유 라디칼을 형성하는데 멜라닌은 이러한 자유 라디칼 등을 제거하여 단백질과 유전자들을 보호해 주는 유용한 역할을 한다.The color of human skin is determined by the amount of melanin, carotene and hemoglobin, among which melanin is the most crucial factor. The melanin pigment is a phenolic polymer substance having a complex form of black pigment and protein. It plays a role of blocking ultraviolet rays, and a person who lacks the melanin pigment is very sensitive to sunlight and is likely to burn, and skin cancer is likely to occur at a young age. On the other hand, ultraviolet rays and carcinogens of short wavelength form harmful free radicals in skin, and melanin plays a useful role to protect proteins and genes by removing such free radicals.

멜라닌은 색소 세포 내에 존재하는 티로시나아제의 작용에 의해 티로신으로부터 복잡한 과정을 거쳐 생성된다. 이 때 생성된 멜라닌은 피부 세포에 전달되고 표피 박리와 함께 멜라닌이 상실되어 소멸되는 순환 작용을 보인다. 이러한 멜라닌 생성 과정은 자연적으로 일어나는 현상으로서, 정상 상태의 피부에서는 멜라닌의 과다 생성이 일어나지 않는다. 그러나 피부가 외부의 자극, 예를 들면 자외선, 환경오염 또는 스트레스 등에 반응하면 멜라닌이 과다 생성되어 피부 밖으로 배출되지 못하고 각질형성세포(keratinocyte)로 전달되어 피부 표피층에 축적되어 기미, 주근깨 및 노인성 흑자 등 심각한 미용상의 문제를 일으킬 뿐만 아니라, 피부노화를 촉진하며 피부암을 유발하기도 한다. Melanin is produced by a complex process from tyrosine by the action of tyrosinase in the pigment cells. The melanin produced at this time is delivered to the skin cells and exhibits a circulating action in which the melanin is lost due to epidermal detachment. This process of melanin production is a naturally occurring phenomenon and does not result in excessive production of melanin in normal skin. However, when the skin responds to external stimuli such as ultraviolet rays, environmental pollution, stress, or the like, melanin is excessively produced and is not discharged out of the skin. It is transferred to keratinocyte and accumulates in the skin surface layer to become stain, freckles, Not only does it cause serious cosmetic problems, it also promotes skin aging and skin cancer.

희고 고운 피부를 갖고자 하는 것은 모든 사람의 한결같은 소망이다. 멜라닌 색소의 생성을 억제할 수 있다면, 미백효과에 의해 하얀 피부를 얻을 수 있을 것이다. 뿐만 아니라, 피부에 과도한 멜라닌 색소의 침착을 방지하거나 또는 이미 침착된 멜라닌 색소의 색을 엷게하는 것에 의해 기미, 주근깨, 흑자와 같은 색소 침착으로 인한 병변을 치료하는 것이 가능하다. 이러한 대표적인 미백제로서 코직산(Kojic acid), 비타민 C, 하이드로퀴논, 알부틴 등이 알려져 있다. 그러나, 코직산은 in vitro 상의 티로시나아제의 저해 능력에 비해 in vivo 상의 멜라닌 생성 억제효과가 미비할 뿐 아니라 제형의 안정성에 문제가 있으며, 최근에는 장기 사용시 간암을 유발할 수 있다고 보고된 바 있다. 비타민 C는 매우 불안정하여 제형 내에서 상 안정성이 낮아 시간이 경과하면서 그 유효성분의 활성도가 떨어지는 문제점이 있다. 최근에는 캡슐 또는 리포좀으로 비타민 C의 제형을 안정화시키기 위한 다양한 방법이 제안되고 있으나 아직 뚜렷한 안정화 방법이 제시되지 못하고 있다. 하이드로퀴논은 미백효과가 우수하나 발암성 물질로 규정되어 그 사용이 제한적이다. 알부틴은 하이드로퀴논에 당이 붙어있는 화합물로서 화장료 등에 적용 시 피부 효소에 의해 당이 분리되면 발암물질인 하이드로퀴논이 형성되어 세포 독성을 유발한다는 문제가 있다. 미백제의 부작용 등이 발표됨에 따라 최근에는 감초, 닥나무 등 생약과 천연물을 이용한 기능성 미백제와 관련하여 다양한 연구 개발이 이루어지고 있으나 대부분의 식물 추출물은 고농도에서만 미백 효능을 나타내고 저농도에서는 거의 효과가 없는 것으로 알려져 있으며 아직까지 그 독성에 대한 검증이 충분하지 못하다. 따라서 소량으로도 효능이 우수하고 부작용이 적은 안전한 대체 미백제의 개발이 시급한 실정이다. It is everyone's constant desire to have white, fair skin. If you can suppress the production of melanin pigment, you will get white skin by the whitening effect. In addition, it is possible to treat lesions caused by pigmentation such as blemishes, freckles, and surpluses by preventing excessive melanin pigmentation on the skin or by thinning the color of the melanin pigment already deposited. Kojiic acid (Kojic acid), vitamin C, hydroquinone, arbutin and the like are known as such a representative whitening agent. However, kojic acid is not only effective in inhibiting melanin production in vivo compared to the inhibitory ability of tyrosinase in vitro, but also has a problem in the stability of the formulation, and has recently been reported to cause liver cancer in long-term use. Vitamin C is very unstable and low phase stability in the formulation has a problem that the activity of the active ingredient is lowered over time. Recently, various methods for stabilizing the formulation of vitamin C in capsules or liposomes have been proposed, but no clear stabilization method has yet been proposed. Hydroquinone has excellent whitening effect but is limited to its use as it is defined as a carcinogenic substance. Arbutin is a compound in which sugar is attached to hydroquinone. When sugar is separated by skin enzymes when applied to cosmetics, hydroquinone, a carcinogen, is formed, causing cytotoxicity. Recently, various researches and developments have been made regarding functional whitening agents using herbal medicines such as licorice and mulberry and natural products as the side effects of whitening agents have been released. However, most plant extracts are known to show whitening efficacy only at high concentrations and have little effect at low concentrations. There is not enough verification of the toxicity. Therefore, there is an urgent need to develop a safe alternative whitening agent that is excellent in small amount and has fewer side effects.

본 발명의 목적은 보다 안전하면서도 우수한 미백 효과를 낼 수 있는 피부 미백용 조성물 또는 이를 포함하는 미백 화장료 조성물을 제공하는 데에 있다.It is an object of the present invention to provide a whitening composition or a whitening cosmetic composition comprising the same, which can produce a safer and superior whitening effect.

본 발명자들은, 하기 반응식 1을 통하여, 인돌린 2-티온 유사체(화합물 1)와 인돌-2-티올 유사체(화합물 2)를 합성한 후, 그들의 멜라노마 B16 세포에서의 멜라닌 생성 억제능을 평가하였다.The present inventors synthesized the indolin 2-thione analogue (compound 1) and the indole-2-thiol analogue (compound 2) through the following reaction scheme 1, and evaluated the melanin production inhibitory ability in these melanoma B16 cells.

반응식 1Scheme 1

Figure 112011059876775-pat00004
Figure 112011059876775-pat00004

상기 반응식 1에서 R1 , R2는, 상기 화학식 I의 R1과 동일하다. R 1 and R 2 in Scheme 1 are the same as R 1 in Formula (I).

상기 반응식 1을 간단히 살펴보면, 이사틴(isatin: 1H-인돌-2,3-디온: 3)으로부터 울프-키쉬너 환원(Wolff-Kishner reduction) 반응에 의해, 중간체 화합물 4를 합성하였다. 12시간 동안 환류 조건에서 피페리딘의 존재하에 화합물 4를 적절한 알데하이드로 반응시켜 화합물 5를 생성하고, 실온조건에서 수소화붕소나트륨을 처리하여 원 팟(one pot)으로 화합물 6을 수득하였다. 한편, 카보닐 화합물 4를 실온 조건에서 하룻밤동안 탄산나트륨의 존재하에서 오황화인(P2S5)으로 처리하여 인돌린-2-티온 화합물 7을 얻었다. 상기 화합물 5를 제조하는 조건과 동일한 조건하에서 인돌린-2-티온 화합물 7을 다양한 알데하이드로 처리하여 화합물 1을 얻었다. 상기 화합물 1을 수소화 붕소나트륨으로 환원하여 화합물 2를 얻었다. 이 반응에서 화합물 8이 생성물로 예상되었다. 그러나, 이 반응은 인돌린-2-티온 화합물 7과 달리, 대응하는 티올 화합물 2로 호변이성질(tautomerism)이 진행되었다. 인돌린-2-티온 화합물 7이 티오아미드 호변이성질체(tautomer)로 존재하는 반면, 3-벤질인돌-2-티온 화합물 8 보다 3-벤질인돌-2-티올 화합물 2가 더 주형태임이 밝혀졌다. 인돌-2-티올 화합물 2의 IR 스펙트럼 2549-2568cm-1 범위에서의 흡수 밴드가, 이 호변이성질체 형태가 주요 구조임을 뒷받침한다. 환류 조건하에서 중간체 화합물 8과 로슨 시약(Lawesson’s reagent)의 반응에서 동일한 결과가 확인되었다. Looking briefly at the reaction scheme 1, intermediate compound 4 was synthesized by Wolf-Kishner reduction reaction from isatitin (1H-indole-2,3-dione: 3 ). Compound 4 was reacted with an appropriate aldehyde in the presence of piperidine at reflux for 12 hours to produce compound 5 , and treated with sodium borohydride at room temperature to yield compound 6 as a one pot. On the other hand, carbonyl compound 4 was treated with phosphorus penta sulfide (P 2 S 5 ) in the presence of sodium carbonate overnight at room temperature to obtain indolin-2-thione compound 7 . Indoline-2-thione compound 7 was treated with various aldehydes under the same conditions as those for preparing compound 5 , to obtain compound 1 . Compound 1 was reduced with sodium borohydride to yield compound 2 . Compound 8 was expected as a product in this reaction. However, this reaction proceeded tautomerism to the corresponding thiol compound 2 , unlike indolin-2-thione compound 7 . While indolin-2-thione compound 7 is present as a thioamide tautomer, it has been found that 3-benzylindole-2-thiol compound 2 is the main form than 3-benzylindole-2-thione compound 8 . The absorption band in the IR spectrum 2549-2568 cm −1 of indole- 2 -thiol compound 2 supports that this tautomeric form is the main structure. The same result was confirmed in the reaction of intermediate compound 8 with Lawson's reagent under reflux conditions.

본 발명자들은, 상기 반응식 1을 통해 합성된 새로운 일련의 화합물들, 즉, 화합물 4, 6, 7, 1, 및 2에 대한 멜라닌 형성 억제능을 측정한 결과, 카보닐 화합물인 화합물 46은 멜라닌 형성 억제 작용을 갖지 않으며, 본 발명의 인돌린-2-티온 화합물 1은, 인돌린-2-티올 화합물 2 보다 우수한 멜라닌 형성 억제 작용을 갖는다는 사실을 확인하였다. 본 발명자들은, 특히, 인돌린-2-티온 화합물 1이, 예상치 못한 우수한 멜라닌 형성 억제 효능을 나타내는 점을 확인하였고, 퀴나졸린-2-티온 화합물과 벤즈이미다졸 2-티온 화합물과 관련하여 3-N은 멜라닌 형성 억제에 기능하지 않을 뿐만 아니라, 티온기(-C=S)가 티올기(-C-SH) 보다 중요한 사실을 확인하였다. The inventors measured melanin formation inhibitory ability against a new series of compounds synthesized through Scheme 1, that is, compounds 4 , 6 , 7 , 1 , and 2 , and as a result, compounds 4 and 6, which are carbonyl compounds, are melanin. It did not have a formation inhibitory effect, and it confirmed that the indolin-2-thione compound 1 of this invention has a melanin formation inhibitory effect superior to the indolin- 2 -thiol compound 2 . In particular, the present inventors have found that indolin-2-thione compound 1 exhibits unexpectedly excellent melanin formation inhibitory effect, and in relation to the quinazoline-2-thione compound and the benzimidazole 2-thione compound, Not only did N not function to inhibit melanin formation, but it was confirmed that the thion group (-C = S) is more important than the thiol group (-C-SH).

이처럼 티온 화합물 1이 티올 화합물 2에 비하여 우수한 활성을 보이는 것은 물리화학적인 성질에 기인할 수 있다. 즉, 생체 시스템에서 티온은 티올 보다 훨씬 더 안정적인 반면, 티올은 다이설파이드(-S-S-)를 형성하기 매우 쉽기 때문에 수용체 자리로 이동할 수 없어서, 그 생체 활성이 감소될 수 있다. 한편, 상기 티온기(C=S)는 티올기(C-SH) 보다 이중 결합 때문에 더 많이 극화되어 있어, 티온이 추정 수용체에 더 강력한 결합을 형성하여 활성을 증가시킬 수 있는 것으로 판단된다.The excellent activity of the thion compound 1 compared to the thiol compound 2 may be due to the physicochemical properties. That is, in a biological system thion is much more stable than thiol, while thiol is very easy to form disulfide (-SS-) and therefore cannot move to the receptor site, thereby reducing its bioactivity. On the other hand, the thion group (C = S) is more polarized due to the double bond than the thiol group (C-SH), it is determined that the thion can form a stronger bond to the putative receptor to increase the activity.

cAMP/단백키나제 A를 통한 멜라닌 생성 억제효과의 측정Measurement of melanogenesis inhibitory effect through cAMP / protein kinase A

알파-멜라노사이트 자극 호르몬을 가한 세포주 멜라노마(melanoma) B16은 cAMP/단백키나제 A의 신호전이를 통하여 멜라닌을 생성한다 (Rasmussen, N., et al ., Neuroendocrinol. Lett ., 20:265-282, 1999; Scott, M. C., et al ., J. Cell . Sci . 115:2349-55, 2002). 상기한 모든 합성된 유도체들은 하기 표 1에 나타낸 바와 같이 멜라노마 B16 세포주에서의 멜라닌 형성에 대한 이들의 억제 활성을 테스트하였다. 본 실험예에서 티로시나아제 자체를 이용하지 않은 이유는 이들 억제제가 멜라닌 형성을 감소시키는데 그 목적이 있기 때문이다. 알파-멜라노사이트 자극 호르몬과 함께 상기한 실시예들에서 제조된 화합물들을 동시에 처리한 후 생성된 멜라닌의 양과, 실시예들의 화합물을 처리하지 않은 경우 생성된 멜라닌 양을 비교하여 하기 수식에 의해 멜라닌 생성 저해효과를 계산하였다. Cell line melanoma B16 with alpha-melanosite stimulating hormone produces melanin through signal transduction of cAMP / protein kinase A (Rasmussen, N., et. al . , Neuroendocrinol. Lett ., 20: 265-282, 1999; Scott, MC, meat al ., J. Cell . Sci . 115: 2349-55, 2002). All synthesized derivatives described above were tested for their inhibitory activity on melanin formation in melanoma B16 cell lines as shown in Table 1 below. The reason why the tyrosinase itself is not used in this experimental example is that these inhibitors have the purpose of reducing melanin formation. Melanin production by comparing the amount of melanin produced after simultaneously treating the compounds prepared in the above embodiments with alpha-melanosite stimulating hormone and the amount of melanin produced when the compounds of the examples were not treated Inhibitory effect was calculated.

보다 구체적으로, 세포주 멜라노마(melanoma) B16을 96-웰 플레이트의 웰당 2,500개씩 분주한 다음 10% 소태반 혈청을 함유한 DMEM 배지에서 37℃, 5% CO2 조건에서 24시간 배양하였다. 상기 멜라노마 B16 세포(CRL6323)는 ATCC(Manassas, USA)에서 구입하였다. 배양 후 알파-멜라노사이트 자극 호르몬(최종농도 10 nM)과 실시예에서 제조한 유도체(1a~1h, 2a~2h) 각각을 다양한 시료농도(30 μM, 10 μM, 또는 1 μM)로 동시에 처리하고 3일간 추가로 배양한 다음 배지로 방출된 멜라닌의 양을 파장 405 nm에서의 흡광도 측정을 통하여 정량하였다. 본 발명에 의한 모든 화합물들은 본 실시예의 측정 농도에서 B16 세포의 성장을 억제하지 않아 세포 독성이 없음을 확인할 수 있었다.More specifically, 2,500 cell lines of melanoma B16 were dispensed per well of a 96-well plate, and then cultured in DMEM medium containing 10% placental serum at 37 ° C. and 5% CO 2 for 24 hours. The melanoma B16 cells (CRL6323) were purchased from ATCC (Manassas, USA). After incubation, each of alpha-melanosite stimulating hormone (final concentration 10 nM) and the derivatives (1a-1h, 2a-2h) prepared in Example were simultaneously treated with various sample concentrations (30 μM, 10 μM, or 1 μM). After further incubation for 3 days, the amount of melanin released into the medium was quantified by measuring absorbance at a wavelength of 405 nm. All the compounds according to the present invention did not inhibit the growth of B16 cells at the measured concentrations of this example was confirmed that there is no cytotoxicity.

10% 소태반 혈청을 함유한 DMEM 배지에서 알파-멜라노사이트 자극 호르몬을 첨가하지 않고 3일간 배양한 세포주 멜라노마(melanoma) B16은 2±6 μg/ml의 멜라닌을 방출하였고, 동일한 배지에 알파-멜라노사이트 자극 호르몬을 첨가하였을 때는 44±4 μg/ml의 멜라닌을 방출하였다.Cell line melanoma B16 cultured in DMEM medium containing 10% fetal placental serum without addition of alpha-melanosite stimulating hormone released 2 ± 6 μg / ml of melanin and alpha- in the same medium. When melanocyte stimulating hormone was added, melanin was released at 44 ± 4 μg / ml.

상기 표 1에서와 같이, R1이 페닐기인 화합물 1a(30에서 >100% 억제율, IC50=1.40)를 비롯하여, 상기 페닐 고리의 4-위치에 메틸(화합물 1b, 30에서 >100% 억제율, IC50=5.2), 에틸(화합물 1c, 30에서 >100% 억제율, IC50=2.5), 클로로(화합물 1d, 30에서 >100% 억제율, IC50=1.4)와 같은 다양한 치환기들을 갖는 일련의 유사체들도 매우 우수한 멜라닌 형성 억제능을 나타내었다. 또한, R1이 확장된 평면 나프틸로 대체된 화합물 1f(30에서 >100% 억제율, IC50=3.4), 벌키 사이클로헥실기로 대체된 화합물 1g(30에서 >100% 억제율, IC50=3.6), 및 R1이 페닐기이고, R2기가 CH3인 화합물 1h(30에서 >100% 억제율, IC50=3.6)로서, 1a 화합물과 거의 비슷한 억제율을 나타낸다. 이 결과는, 화합물 1의 페닐 고리가 벌키 소수성 부분으로 대체될 수 있으며, 멜라닌 생성의 효율적인 억제에 화합물의 친유성(lipophilicity)이 중요함을 의미한다고 하겠다. As shown in Table 1 above, compound 1a (> 30% inhibition at 30, IC 50 = 1.40) in which R 1 is a phenyl group, methyl at the 4-position of the phenyl ring (compound 1b,> 100% inhibition at 30, Series of analogues with various substituents such as IC 50 = 5.2), ethyl (compound 1c,> 100% inhibition at 30, IC 50 = 2.5), chloro (compound 1d,> 100% inhibition at 30, IC 50 = 1.4) Also showed very good melanin formation inhibitory ability. In addition, compound 1f with R 1 replaced with expanded planar naphthyl (> 100% inhibition at 30, IC 50 = 3.4), 1 g of compound replaced with bulky cyclohexyl group (> 100% inhibition at 30, IC 50 = 3.6 ), And compound 1h (> 100% inhibition at 30, IC 50 = 3.6), wherein R 1 is a phenyl group and the R 2 group is CH 3 , showing a similar inhibition rate to compound 1a. This result suggests that the phenyl ring of compound 1 can be replaced with a bulky hydrophobic moiety and that the lipophilicity of the compound is important for the efficient inhibition of melanogenesis.

한편, 인돌 2-티올 유사체 화합물 2a(30에서 53% 억제율, IC50=24.2)는, 대응하는 티온 1a 화합물 보다 낮은 멜라닌 생성 억제능을 나타내어, 티온기(-C=S)가 티올기(-C-SH) 보다 중요함을 확인할 수 있었다. 화합물 2b(30에서 85 % 억제율, IC50=14.0), 화합물 2c(30에서 89% 억제율, IC50=12.1), 화합물 2d(30에서 79% 억제율, IC50=14.3), 화합물 2e(30에서 55% 억제율, IC50=18.2), 화합물 2f(30에서 59% 억제율, IC50=15.6), 화합물 2g (30에서 <10% 억제율, IC50=>30), 및 화합물 2h(30에서 54% 억제율, IC50=21.2)에서 나타난 바와 같이, 티올 화합물 2의 유사체들에서 방향족기의 치환기 및 크기에 불구하고 동일하게, 대응하는 인돌린-2-티온 유사체 보다 낮은 멜라닌 억제 효능을 나타내었다. On the other hand, indole 2-thiol analogue compound 2a (53% inhibition at 30, IC 50 = 24.2) exhibited lower melanin production inhibition than the corresponding thion 1a compound, so that the thion group (-C = S) is a thiol group (-C -SH) was more important than. Compound 2b (85% inhibition at 30, IC 50 = 14.0), Compound 2c (89% inhibition at 30, IC 50 = 12.1), Compound 2d (79% inhibition at 30, IC 50 = 14.3), Compound 2e (at 30 55% inhibition, IC 50 = 18.2), Compound 2f (59% inhibition at 30, IC 50 = 15.6), Compound 2g (<10% inhibition at 30, IC 50 => 30), and Compound 2h (54% at 30) As shown in the inhibition rate, IC 50 = 21.2), the analogs of thiol compound 2 exhibited lower melanin inhibitory efficacy than the corresponding indolin-2-thione analogs, despite the substituents and size of the aromatic groups.
