Description
본 발명은 κ-오피오이드 수용체의 아고니스트를 포함하는 피부 미백용 또는 색소 침착 장애의 예방, 개선 또는 치료 조성물에 관한 것이다. The present invention relates to a composition for skin whitening or for preventing, improving or treating pigmentation disorders, comprising an agonist of the κ-opioid receptor.
피부는 자외선 노출로부터 우리를 보호할 수 있는 신체의 가장 큰 기관으로, 멜라닌 세포는 피부세포에서 각질 세포로 둘러싸여 있어 멜라닌 색소를 전달한다. 멜라닌 세포에는 멜라닌을 함유하는 세포 소기관인 멜라노솜과 멜라닌 세포에서 발견되는 리소솜 관련 세포 기관이 있다. 멜라닌 합성 과정에서 멜라닌이 과도하거나 부족하게 생성되면 기미, 백색증 및 백반증을 비롯한 피부 변색을 유발하는 일부 색소 침착 장애가 발생한다고 알려져 있다.The skin is the body's largest organ that can protect us from UV exposure, and melanocytes are surrounded by keratinocytes in the skin cells and deliver melanin pigment. Melanocytes include melanosomes, organelles that contain melanin, and lysosome-related organelles found in melanocytes. It is known that when melanin is produced excessively or insufficiently during the melanin synthesis process, some pigmentation disorders that cause skin discoloration, including freckles, albinism, and vitiligo, occur.
멜라노솜은 멜라노파지라고 하는 선택적 자가포식에 의해 분해된다고 보고되는데, 멜라노파지는 오토파지의 한 유형이다. 오토파지(Autophagy)는 잘못 접히거나 응집된 단백질을 제거하고 손상된 세포 소기관을 제거하는 자가 분해 과정으로, 크게 매크로파지(macroautophagy), 마이크로파지(microautophagy) 및 샤프론(chaperone) 매개 오토파지의 세 가지 유형이 있다. 그 중 가장 많이 연구된 매크로파지는 거대자가포식이 발생하면 분리막이 세포질의 일부를 둘러싸고 세포내 이중막 결합 구조인 자가포식소체를 형성한다. 그런 다음, 오토파고좀(autophagosome)이 리소좀(lysosome)과 융합하여 오토리소좀(autolysosome)을 형성하여 분해된다. It is reported that melanosomes are degraded by selective autophagy called melanophage, which is a type of autophagy. Autophagy is an autolytic process that removes misfolded or aggregated proteins and damaged organelles. It is broadly divided into three types: macroautophagy, microautophagy, and chaperone-mediated autophagy. there is. Among them, macrophages, the most studied, form an autophagosome, an intracellular double-membrane structure, when macroautophagy occurs, a separation membrane surrounds part of the cytoplasm. Then, the autophagosome fuses with the lysosome to form an autolysosome and is decomposed.
한편, 호르몬은 신체 전체의 다양한 세포와 조직의 활동을 가능하게 하는 화학적 전달자로 일반적으로 호르몬은 고친화성 수용체와 상호작용한다. 다양한 유형의 수용체 중 오피오이드 수용체는 뇌에 널리 분포되어 있으며 척수 및 말초 감각 및 자율 신경에서 발견된다. 또한, 멜라닌 세포, 각질 세포 및 섬유아세포와 같은 피부 세포에서도 발현된다. 오피오이드 수용체는 2차 메신저 시스템을 통해 단백질 인산화에 영향을 줄 수 있는 G 단백질 결합 수용체(GPCR)로, 구조적 상동성을 가진 세 가지 오피오이드 수용체 유형으로 μ(또는 MOR), δ(또는 DOR) 및 κ(또는 KOR)이 있다. 그 중 KOR은 천연 내인성 리간드로 중추 신경계에서 발현되며, 소양증 등에서 중요한 역할을 한다고 보고된다.Meanwhile, hormones are chemical messengers that enable the activities of various cells and tissues throughout the body, and hormones generally interact with high-affinity receptors. Among the various types of receptors, opioid receptors are widely distributed in the brain and are found in the spinal cord and peripheral sensory and autonomic nerves. It is also expressed in skin cells such as melanocytes, keratinocytes, and fibroblasts. Opioid receptors are G protein-coupled receptors (GPCRs) that can affect protein phosphorylation through second messenger systems. There are three types of opioid receptors with structural homology: μ (or MOR), δ (or DOR), and κ. (or KOR). Among them, KOR is a natural endogenous ligand expressed in the central nervous system and is reported to play an important role in pruritus.
그 중, 날푸라핀(Nalfurafine, TRK-820)은 요독증 및 만성 통증 간 질환 환자의 가려움증을 치료하는 데 사용되는 고도의 선택적 KOR 아고니스트로, 혐오감 없이 항통각수용성을 생성하는 것으로 보고된다. 그러나, 멜라닌 생성에 대하여 날푸라핀과 같은 KOR 아고니스트가 미치는 영향은 아직 보고된 바 없다.Among them, nalfurafine (TRK-820) is a highly selective KOR agonist used to treat itching in patients with uremia and chronic painful liver disease, and is reported to produce antinociception without aversion. However, the effect of KOR agonists such as nalfurafine on melanin production has not yet been reported.
이러한 배경 하에, 본 발명자는 날푸라핀과 같은 KOR 아고니스트가 피부세포 내 멜라노파지를 유도하여 멜라노솜 분해를 촉진함으로써, 피부미백을 비롯하여 색소침착 관련 질환의 예방, 개선 또는 치료에 있어 효과적임을 확인하였으며, KOR 아고니스트의 새로운 멜라노파지 조절제로의 가능성을 확인함으로써 본 발명을 완성하였다.Against this background, the present inventor confirmed that KOR agonists such as nalfurafine are effective in preventing, improving, or treating diseases related to pigmentation, including skin whitening, by inducing melanophage in skin cells and promoting melanosome decomposition.

상기 용어, "PKA(protein kinase A)"는 카이네이즈(kinase)의 하나로 세포내 사이클릭 AMP (cAMP) 의존적으로 활성화되는 단백질이며 cAMP-dependent protein kinase로도 알려져 있다. 이의 기능은 다양한 대사 조절 세포들에서 에너지 대사 및 세포 분열 관련 신호전달, 전자조절단백질 활성 등 매우 다양한 기능을 조절하는 것으로 알려져 있다. The term "PKA (protein Kinase A)" is a protein that is activated in a cellular cyclic AMP (cAMP)-dependent manner as one of the kinases, and is also known as cAMP-dependent protein kinase. Its function is known to regulate a wide variety of functions, such as energy metabolism, cell division-related signaling, and electron regulatory protein activity, in various metabolic regulatory cells.
본 발명의 구체적인 일 실시예에서는, 날푸라핀 염산염 처리가 α-MSH로 자극된 B16F1 세포에서 PKA의 인산화를 억제하는 것을 확인하였다. 이로써 피부세포에서 κ-오피오이드 수용체 매개 멜라노파지의 잠재적인 조절 메커니즘을 확인하였다. 이러한 결과는 κ-오피오이드 수용체 작용제가 B16F1 세포에서 PKA 활성화를 억제함으로써 멜라닌 소화작용을 유도하는 것을 시사한다.In a specific example of the present invention, it was confirmed that nalfurafine hydrochloride treatment inhibits the phosphorylation of PKA in B16F1 cells stimulated with α-MSH.

실시예 1: B16F1 세포에서 날푸라핀 염산염의 α-MSH 자극 멜라닌 생성 억제 효과 확인Example 1: Confirmation of the inhibitory effect of nalfurafine hydrochloride on α-MSH-stimulated melanin production in B16F1 cells
오토파지는 피부 노화의 중요한 메커니즘이므로, 피부에서 새로운 자가포식 조절자를 식별하기 위해, B16F1 세포(B16F1/GFP-LC3)에서 자가포식 모니터링 단백질을 과도하게 사용하는 GFP-LC3를 사용하여 부실 세포주를 설정하고 내분비학-호르몬 라이브러리로 세포 기반 고함량 스크리닝하여 B16F1 세포에서 강력한 자가포식 유도제로 날푸라핀 염산염을 확인하였다. 이러한 스크리닝 결과를 확인하기 위해, 날푸라핀 염산염 또는 강력한 자가포식 유도제로 보고된 ARP101로 B16F1/GFP-LC3 세포에 처리하였다. Since autophagy is an important mechanism of skin aging, to identify new autophagy regulators in the skin, we established a stale cell line using GFP-LC3 overusing autophagy monitoring protein in B16F1 cells (B16F1/GFP-LC3). And through cell-based high-content screening with an endocrinology-hormone library, nalfurafine hydrochloride was identified as a potent autophagy inducer in B16F1 cells. To confirm these screening results, B16F1/GFP-LC3 cells were treated with nalfurafine hydrochloride or ARP101, which has been reported to be a potent autophagy inducer.
그 결과, 도 1a 및 도 1b에서 확인할 수 있는 바와 같이, 날푸라핀 염산염이 처리된 세포에서 점상 GFP-LC3 단백질의 형성이 현저히 증가하는 것을 확인하였다(도 1a 및 도 1b). As a result, as can be seen in Figures 1a and 1b, the formation of punctate GFP-LC3 protein was confirmed to significantly increase in cells treated with nalfurafine hydrochloride (Figures 1a and 1b).
또한, 날푸라핀 염산염에 의해 증가된 자가포식 플럭스(flux)를 확인하기 위해, 자가포식소체와 리소좀의 융합 억제제인 바필로마이신 A1(Baf)을 B16F1 세포를 처리하거나 처리하지 않았다. 그 결과, LC3-±의 단백질 수준은 화합물 단독으로 처리된 세포보다 날푸라핀 염산염 및 바필로마이신 A1이 모두 처리된 세포에서 더 많이 축적되는 것을 확인하였다. 이러한 결과는 ARP101과 유사하게 날푸아르핀 염산염이 B16F1 세포에서 강력한 자가포식 유도제임을 나타내는 것이다.In addition, to confirm the increased autophagy flux by nalfurafine hydrochloride, B16F1 cells were treated or not with bafilomycin A1 (Baf), an inhibitor of fusion of autophagosomes and lysosomes. As a result, it was confirmed that the protein level of LC3-± accumulated more in cells treated with both nalfurafine hydrochloride and bafilomycin A1 than in cells treated with the compound alone. These results indicate that, similar to ARP101, nalpuarpine hydrochloride is a strong autophagy inducer in B16F1 cells.
최근 자가포식 유도가 멜라닌 함량에 영향을 미친다고 보고되고 있어(Park HJ, BBRC, 2020), 날푸라핀 염산염 처리 세포에서의 멜라닌 함량을 추가로 분석하여 미백 효과를 확인하였다. 구체적으로, α-MSH로 자극된 B16F1 세포를 날푸라핀 염산염과 함께 배양하였으며, 이 때 강력한 항멜라닌 생성제로 알부틴을 사용하였다. 그 결과, 알부틴이 처리된 α-MSH 처리된 세포에서 멜라닌 함량이 높게 축적되는 것을 확인하였다. 반면, α-MSH에 의한 강력한 멜라닌 생성에도 불구하고, 날푸라핀 염산염의 처리는 B16F1 세포에서 멜라닌 함량을 유의하게 감소시키는 것을 확인하였다(도 1c).Recently, it has been reported that autophagy induction affects melanin content (Park HJ, BBRC, 2020), so the whitening effect was confirmed by further analyzing the melanin content in cells treated with nalfurafine hydrochloride. Specifically, B16F1 cells stimulated with α-MSH were cultured with nalfurafine hydrochloride, and arbutin was used as a potent antimelanogenic agent. As a result, it was confirmed that melanin content was highly accumulated in arbutin-treated α-MSH-treated cells. On the other hand, despite strong melanin production by α-MSH, treatment with nalfurafine hydrochloride significantly reduced melanin content in B16F1 cells (Figure 1c).
추가로, B16F1 세포주에 자가포식 조절 유전자의 전사인자로 알려진 TFEB-GFP를 과발현시킨 후, 날푸라핀 염산염의 농도별 처리에 따른 TFEB-GFP 세포내 위치변화를 확인해 보았다. 그 결과, 도 1d에서 확인할 수 있듯이, 날푸라핀 염산염의 농도별 처리에 따라 TFEB-GFP가 핵으로 이동하여 활성화되는 것을 확인하였다(도 1d에서, 상단 우측, 하단 좌측). 여기에서 mTOR 단백질 저해제로 TFEB의 핵 이동을 촉진시키는 화합물로 알려진 Torin1(TOCRIS, Bristol, UK)을 양성 대조 물질로 사용하였다.Additionally, after overexpressing TFEB-GFP, known as a transcription factor for autophagy regulatory genes, in the B16F1 cell line, changes in the intracellular location of TFEB-GFP according to treatment with different concentrations of nalfurafine hydrochloride were confirmed. As a result, as can be seen in Figure 1d, it was confirmed that TFEB-GFP moves to the nucleus and is activated according to treatment with nalfurafine hydrochloride at different concentrations (Figure 1d, top right, bottom left). Here, Torin1 (TOCRIS, Bristol, UK), a compound known to promote nuclear translocation of TFEB as an mTOR protein inhibitor, was used as a positive control.
마지막으로, 날푸라핀 염산염 처리시의 mTOR 저해 효과를 확인하기 위해, B16F1 세포주에 a-MSH와 날푸라핀 염산염 처리 후 mTOR에 의해 활성화되는 p70S6K 단백질의 인산화를 웨스턴 블랏을 통해 확인해 보았다. 그 결과, 도 1e에서 확인할 수 있듯이, a-MSH 처리에 의해 증가한 p70S6K 인산화가 날푸라핀 염산염 처리에 의해 저해됨을 확인하였다. 이로써, 날푸라핀 염산염에 의해 자가포식 작용이 촉진 내지 활성화되는 것을 확인할 수 있었다.Finally, to confirm the effect of mTOR inhibition upon treatment with nalfurafine hydrochloride, the phosphorylation of p70S6K protein activated by mTOR was confirmed through Western blotting after treatment with a-MSH and nalfurafine hydrochloride in the B16F1 cell line. As a result, as can be seen in Figure 1e, it was confirmed that p70S6K phosphorylation increased by a-MSH treatment was inhibited by nalfurafine hydrochloride treatment. As a result, it was confirmed that autophagy was promoted or activated by nalfurafine hydrochloride.
종합하면, 날푸라핀 염산염은 자가포식 작용을 촉진 및 활성화할 수 있을 뿐 아니라, 멜라닌 함량을 효과적으로 감소시켜 미백 활성을 나타냄을 확인할 수 있었다.In summary, it was confirmed that nalfurafine hydrochloride can not only promote and activate autophagy, but also exhibit whitening activity by effectively reducing melanin content.

상기 실시예 1에서 날푸라핀 염산염이 멜라닌 함량을 감소시키고 B16F1 세포에서 자가포식을 유도하는 것을 확인한 것을 토대로, 날푸라핀 염산염이 멜라노포식, 즉 멜라노파지에 미치는 영향을 추가로 확인하였다. Based on the confirmation in Example 1 that nalfurafine hydrochloride reduces melanin content and induces autophagy in B16F1 cells, the effect of nalfurafine hydrochloride on melanophagy, that is, melanophage, was further confirmed.
먼저, 멜라노솜 막 단백질인 TPC2와 탠덤 형광 태그(mRFP-EGFP)가 연속되는 멜라노파지 모니터링 시스템을 개발하였다. 자가포식 플럭스 분석을 위한 mRFP-GFP-LC3 단백질과 유사하게, 직렬 분석의 기본 원리는 적색(mRFP) 및 녹색(EGFP) 형광 단백질(참조)의 pH 안정성 차이를 기반으로 한다. 멜라노파지 동안 표적화된 멜라노좀은 자가포식소체로 둘러싸이고, 이는 후속적으로 리소좀으로 수송된다. 리소좀에서 GFP는 RFP보다 산에 더 민감하기 때문에 녹색 형광 신호는 쉽게 소멸되는 반면, 적색 신호는 훨씬 더 안정적으로 남아 있어 멜라노파지 과정을 암시한다. 이 모니터링 시스템에 기초하여, α-MSH로 미리 자극된 B16F1/TPC2-mRFP-EGFP 세포를 바필로마이신 A1의 존재 또는 부재하에 날푸라핀 염산염으로 처리하고 그 결과를 도 2에 나타내었다. First, we developed a melanophage monitoring system in which TPC2, a melanosome membrane protein, and a tandem fluorescent tag (mRFP-EGFP) are sequential. Similar to the mRFP-GFP-LC3 protein for autophagic flux analysis, the basic principle of tandem analysis is based on the differences in pH stability of red (mRFP) and green (EGFP) fluorescent proteins (reference). During melanophage, targeted melanosomes are surrounded by autophagosomes, which are subsequently transported to lysosomes. In lysosomes, GFP is more sensitive to acid than RFP, so the green fluorescence signal quenches easily, while the red signal remains much more stable, suggesting a melanophage process. Based on this monitoring system, B16F1/TPC2-mRFP-EGFP cells pre-stimulated with α-MSH were treated with nalfurafine hydrochloride in the presence or absence of bafilomycin A1, and the results are shown in Figure 2.
그 결과, 도 2a에 나타난 바와 같이, 날푸라핀 염산염으로 처리하면 B16F1/TPC2-mRFP-EGFP 세포에서 바필로마이신 A1에 의해 효율적으로 차단된 RFP 양성점이 현저하게 증가하는 것을 확인하였다(도 2a). As a result, as shown in Figure 2a, it was confirmed that treatment with nalfurafine hydrochloride significantly increased the number of RFP-positive dots efficiently blocked by bafilomycin A1 in B16F1/TPC2-mRFP-EGFP cells (Figure 2a) .
멜라노솜 소기관의 선택적 자가포식을 확인하기 위하여, 날푸라핀 염산염 처리 세포에서 미토콘드리아, ER 및 과산화소체를 포함한 다른 소기관을 추가로 확인하였다. 구체적으로, B16F1 세포를 48시간 동안 α-MSH(0.5μM)로 전처리한 다음, 날푸라핀 염산염(Nalf, 100μM)과 함께 추가로 인큐베이션하였다. 세포를 수확하고 표시된 항체(TYR: 티로시나제(멜라노솜, ABCD3(퍼옥시솜), TOMM20(미토콘드리아), P4HB(소포체), FTCD(골지))로 웨스턴 블롯팅하여 분석하였다. 그 결과, 상기 결과와 일관되게, 멜라노솜 단백질이 날푸라핀 염산염 처리 세포에서 자가포식 과정으로 분해되는 것을 확인하였다(도 2b). 반면, 다른 미토콘드리아 단백질, ER 단백질, 또는 퍼옥시솜 단백질은 날푸라핀 염산염 처리된 세포에서 극적으로 분해되지 않았다(도 2b). 이러한 결과는 날푸라핀 염산염이 멜라노솜 소기관을 선택적으로 자가포식하여 멜라노솜 분해를 유도함을 시사하는 것이다.To confirm selective autophagy of melanosome organelles, other organelles including mitochondria, ER, and peroxisomes were further identified in nalfurafine hydrochloride-treated cells. Specifically, B16F1 cells were pretreated with α-MSH (0.5 μM) for 48 hours and then further incubated with nalfurafine hydrochloride (Nalf, 100 μM). Cells were harvested and analyzed by Western blotting with the indicated antibodies (TYR: tyrosinase (melanosome, ABCD3 (peroxisome)), TOMM20 (mitochondria), P4HB (endoplasmic reticulum), FTCD (Golgi)). As a result, the above results Consistently, it was confirmed that melanosome proteins were degraded by autophagy in cells treated with nalfurapine hydrochloride (Figure 2b), whereas other mitochondrial proteins, ER proteins, or peroxisomal proteins were degraded in cells treated with nalfurapine hydrochloride. was not dramatically decomposed (Figure 2b). This result suggests that nalfurafine hydrochloride induces melanosome decomposition through selective autophagy of melanosome organelles.
다음으로, 날푸라핀 염산염으로 유도된 멜라노파지에 대한 자가포식 활성화 억제 효과를 추가로 확인하였다. ATG5는 오토파고좀에서 파고포릭(phagophoric) 막 확장에 관여하는 필수 오토파지 조절 단백질로, ATG5의 손실은 자가포식 활성화를 가장 완전히 차단하는 것으로 보고된다. 이러한 보고와 유사하게, 도 3a에서 확인할 수 있는 것처럼, ATG5 고갈이 날푸라핀 염산염 처리 세포에서 자가포식 활성화를 억제하는 것을 확인하였다(도 3a). 또한, ATG5 고갈이 α-MSH로 자극된 B16F1 세포에서 날푸라핀 염산염에 의한 멜라닌 함량 감소를 억제하는 것도 확인하였다(도 3b). 더욱이, ATG5 고갈이 날푸라핀 염산염 처리된 세포에서 감소된 수준의 티로시나아제를 회복시키는 것도 확인하였다(도 3b). Next, the inhibitory effect of autophagy activation on melanophage induced by nalfurafine hydrochloride was further confirmed. ATG5 is an essential autophagy regulatory protein involved in phagophoric membrane expansion in autophagosomes, and loss of ATG5 is reported to most completely block autophagy activation. Similar to these reports, it was confirmed that ATG5 depletion inhibited autophagy activation in cells treated with nalfurafine hydrochloride, as shown in Figure 3a ( Figure 3a ). In addition, it was confirmed that ATG5 depletion inhibited the reduction of melanin content by nalfurafine hydrochloride in B16F1 cells stimulated with α-MSH (Figure 3b). Moreover, we confirmed that ATG5 depletion restored the reduced level of tyrosinase in cells treated with nalfurafine hydrochloride (Figure 3b).
종합하면, 이러한 결과는 날푸라핀 염산염이 B16F1 세포에서 멜라노파지를 촉진하여 멜라노솜 분해를 유도함을 시사하는 것이다.Taken together, these results suggest that nalfurafine hydrochloride promotes melanophage in B16F1 cells and induces melanosome degradation.
실시예 3: B16F1 세포에서 κ-오피오이드 수용체 작용제의 멜라노파지 유도 효과Example 3: Melanophage-inducing effect of κ-opioid receptor agonists in B16F1 cells
날푸라핀 염산염은 선택적 카파(κ)-오피오이드 수용체 작용제로(Nakao K et al., J Pharma Sci 2016), 다른 선택적 카파(κ)-오피오이드 수용체 작용제가 날푸라핀 염산염과 유사하게 B16F1 세포에서 멜라노파지를 유도하는지 확인하였다.Nalfurafine hydrochloride is a selective kappa(κ)-opioid receptor agonist (Nakao K et al., J Pharma Sci 2016), and other selective kappa(κ)-opioid receptor agonists, similar to nalfurafine hydrochloride, inhibit melanocytes in B16F1 cells. It was confirmed whether phage was induced.
멜라노파지 유도 여부 확인은 상기 실시예 2에서 확인한 방법과 같다. Confirmation of melanophage induction is the same as the method confirmed in Example 2 above.
그 결과, 날푸라핀 염산염의 처리 결과와 유사하게, 다른 선택적 카파(κ)-오피오이드 수용체 작용제인 MCOPPB 또는 미안세린의 경우에도, B16F1 세포에서 GFP-LC3 및 LC3 ±축적이 있는 자가포식 반점이 높게 유도되는 것을 확인할 수 있었다(도 4a, 도 4b). 또한, MCOPPB와 미안세린 모두 α-MSH로 자극된 B16F1 세포에서 과도한 멜라닌 함량을 유의하게 억제함으로써 피부 미백 효과를 가짐을 알 수 있었다(도 4c). 종합하면, 이러한 결과는 κ-오피오이드 수용체 작용제가 κ-오피오이드 수용체를 활성화하여, B16F1 세포에서 멜라노파지를 효과적으로 유도함을 시사하는 것이다.As a result, similar to the results of treatment with nalfurafine hydrochloride, other selective kappa(κ)-opioid receptor agonists, MCOPPB or mianserin, resulted in high levels of autophagic spots with GFP-LC3 and LC3 accumulation in B16F1 cells. It was confirmed that it was induced (Figures 4a, 4b). In addition, both MCOPPB and mianserin were found to have a skin whitening effect by significantly suppressing excessive melanin content in B16F1 cells stimulated with α-MSH (Figure 4c). Taken together, these results suggest that κ-opioid receptor agonists effectively induce melanophage in B16F1 cells by activating κ-opioid receptors.
실시예 4: 날푸라핀 염산염은 세포에서 PKA를 억제하여 멜라노파지를 매개함Example 4: Nalfurafine hydrochloride mediates melanophage by inhibiting PKA in cells
B16F1 세포에서 κ-오피오이드 수용체 매개 멜라노파지의 잠재적인 조절 메커니즘을 확인하였다. 그 결과, 도 5a에서 확인할 수 있는 바와 같이, 날푸라핀 염산염 처리가 α-MSH로 자극된 B16F1 세포에서 PKA의 인산화를 억제하는 것을 확인하였다(도 5a). 그러나 이는 아데닐 사이클레이즈(adenylyl cyclase)의 활성화로 세포 내 cAMP 수준을 직접 증가시키는 포스콜린(forskolin) 처리에 의해 고도로 회복되는 것을 확인하였다(도 5a). 따라서 날푸라핀 염산염 처리 세포에서 멜라닌 포식에 대한 PKA의 억제 효과를 추가로 확인해 보았다. 그 결과, 도 5B에서 확인할 수 있는 것과 같이, 날푸라핀 염산염에 의한 강화된 GFP-LC3 반점이 특히 포스콜린과의 조합으로 크게 감소되는 것을 확인할 수 있었다(도 5b). 또한, 포스콜린 처리는 B16F1/TPC2-mRFP-EGFP 세포에서 날푸라핀 염산염에 의한 멜라노솜의 자가포식 분해를 유의하게 억제하는 것을 확인하였다(도 5c). 나아가, 날푸라핀 염산염으로 처리하여 감소된 멜라닌 함량이 α-MSH로 자극된 B16F1 세포에서 포스콜린과의 조합 처리로 역전되는 것을 확인하였다(도 5d). The potential regulatory mechanism of κ-opioid receptor-mediated melanophage was identified in B16F1 cells. As a result, as can be seen in Figure 5a, it was confirmed that nalfurafine hydrochloride treatment inhibited the phosphorylation of PKA in B16F1 cells stimulated with α-MSH (Figure 5a). However, it was confirmed that this was highly recovered by treatment with forskolin, which directly increases intracellular cAMP levels through activation of adenylyl cyclase (Figure 5a). Therefore, we further confirmed the inhibitory effect of PKA on melanin phagocytosis in cells treated with nalfurafine hydrochloride. As a result, as can be seen in Figure 5B, it was confirmed that the GFP-LC3 spots enhanced by nalfurafine hydrochloride were significantly reduced, especially in combination with forskolin (Figure 5b). In addition, it was confirmed that forskolin treatment significantly inhibited the autophagic degradation of melanosomes caused by nalfurafine hydrochloride in B16F1/TPC2-mRFP-EGFP cells (Figure 5c). Furthermore, it was confirmed that the melanin content decreased by treatment with nalfurafine hydrochloride was reversed by combined treatment with forskolin in B16F1 cells stimulated with α-MSH (Figure 5d).
이러한 결과는 κ-오피오이드 수용체 작용제가 B16F1 세포에서 PKA 활성화를 억제함으로써 멜라닌 소화작용을 유도하는 것을 시사한다.These results suggest that κ-opioid receptor agonists induce melanin digestion by inhibiting PKA activation in B16F1 cells.
종합하면 KOR를 활성화하는 날푸라핀 염산염, MCOPPB 및 미안세린과 같은 KOR 작용자가 멜라노파지를 유도하여 멜라노솜 분해를 효과적으로 촉진하고 멜라닌 세포의 색소 침착을 감소시켜 우수한 피부 미백제 또는 과색소침착 질환의 예방, 개선 또는 치료에 사용할 수 있고, 자가포식 유도제로 활용이 가능함을 알 수 있다. Taken together, KOR agonists such as nalfurafine hydrochloride, MCOPPB and mianserin that activate KOR induce melanophage, effectively promote melanosome degradation and reduce pigmentation of melanocytes, making it an excellent skin whitener or prevention of hyperpigmentation disease. , it can be used for improvement or treatment, and it can be used as an autophagy inducer.
