Description

노인성 황반변성의 예방 또는 치료를 위한 약학 조성물Pharmaceutical composition for preventing or treating age-related macular degeneration
본 발명은 노인성 황반변성의 예방 또는 치료를 위한 약학 조성물에 관한 것이다.The present invention relates to a pharmaceutical composition for preventing or treating age-related macular degeneration.
노인성 황반변성(age-related macular degeneration: AMD)은 나이가 들면서 망막의 황반부에 여러 가지 변화가 동반되어 생기는 질병이다. 나이가 증가함에 따라 발생율이 증가하며, 선진국에서는 성인 실명 원인 1위 질환으로 전세계적으로 약 2억명 정도의 환자가 있는 것으로 알려져 있다. 따라서 우리나라에서도 앞으로 노인 인구가 증가함에 따라서 그 발생 빈도는 더욱 증가하리라 예상된다. 황반은 망막이라고 하는 신경 조직의 중심 부위를 말하는데, 빛 자극에 반응하는 광수용체 세포가 밀집되어 있어 중심 시력을 담당한다. 노인성 황반변성은 노화가 진행됨에 따라 이러한 황반부 광수용체 세포가 소실되어 시력 장애를 일으키는 것으로, ① 습성 또는 삼출성 형태와 ② 건성 또는 비삼출성 형태로 나눌 수 있다. Age-related macular degeneration (AMD) is a disease caused by various changes in the macular area of the retina with aging. The incidence increases with age, and it is known that there are about 200 million patients worldwide as the number one cause of adult blindness in developed countries. Therefore, as the elderly population increases in Korea, the incidence is expected to increase further. The macula refers to the central part of the nerve tissue called the retina, and is responsible for central vision because photoreceptor cells that respond to light stimulation are concentrated. Age-related macular degeneration is a loss of these macular photoreceptor cells as aging progresses and causes visual impairment, and can be divided into ① wet or exudative form and ② dry or non-exudative form.
습성(wet=neovascular, exudative) 형태는 망막 밑에 맥락막 신생혈관이 자라는 경우로 항혈관내피성장인자 항체(Anti-vascular endothelial growth factor (VEGF) monoclonal antibody)를 안구내 주사하는 방법으로 치료한다. 건성(dry=atrophic) 형태는 AMD의 대부분을 차지하며 망막에 드루젠(drusen)이나 색소이상(pigmentary abnormality), 또는 망막상피의 위축(atrophy)과 같은 병변이 생긴 경우를 말한다. 건성 중 진행성 황반변성을 지도형 위축(geographic atrophy: GA)라고 하는데, 현재로서는 치료법이 전무하여 노인성 황반변성의 최대 난제인 실정이다.In the wet = neovascular, exudative form, when choroidal neovascularization grows under the retina, it is treated by intraocular injection of anti-vascular endothelial growth factor (VEGF) monoclonal antibody. The dry (atrophic) form accounts for most of AMD and refers to cases in which lesions such as drusen, pigmentary abnormalities, or atrophy of the retinal epithelium occur in the retina. Progressive macular degeneration during dryness is called geographic atrophy (GA), and currently there is no treatment, which is the biggest challenge in age-related macular degeneration.
따라서 본 발명은 상기와 같은 문제의 해결을 위해 고안된 것으로, 본 발명은 노인성 황반변성의 예방 또는 치료를 위한 약학 조성물에 관한 것이다. 본 발명의 약학조성물은 습성뿐만 아니라 치료법이 전무한 건성의 노인성 황반변성에서도 매우 현저한 치료 효과를 발휘하였으므로, 의료 분야에서 크게 이용될 수 있을 것으로 기대된다.Therefore, the present invention was conceived to solve the above problems, and the present invention relates to a pharmaceutical composition for preventing or treating age-related macular degeneration. The pharmaceutical composition of the present invention is expected to be widely used in the medical field because it exhibited a very remarkable therapeutic effect not only in wet but also in dry age-related macular degeneration for which there is no treatment.

본 발명의 일 구체예에서 “노인성 황반변성(Age-related macular degeneration: AMD)”이란, 나이가 들면서 망막의 황반부에 여러 가지 변화가 동반되어 생기는 질병이다. 나이가 증가함에 따라 발생율이 증가하며, 선진국에서는 성인 실명 원인 1위 질환으로 전세계적으로 약 2억명 정도의 환자가 있는 것으로 알려져 있다. 따라서 우리나라에서도 앞으로 노인 인구가 증가함에 따라서 그 발생 빈도는 더욱 증가하리라 예상된다. 황반은 망막이라고 하는 신경 조직의 중심 부위를 말하는데, 빛 자극에 반응하는 광수용체 세포가 밀집되어 있어 중심 시력을 담당한다. 노인성 황반변성은 노화가 진행됨에 따라 이러한 황반부 광수용체 세포가 소실되어 시력 장애를 일으키는 것으로, ① 습성 또는 삼출성 형태와 ② 건성 또는 비삼출성 형태로 나눌 수 있다. In one embodiment of the present invention, “Age-related macular degeneration (AMD)” is a disease caused by various changes in the macular region of the retina with aging. The incidence increases with age, and it is known that there are about 200 million patients worldwide as the number one cause of adult blindness in developed countries. Therefore, as the elderly population increases in Korea, the incidence is expected to increase further. The macula refers to the central part of the nerve tissue called the retina, and is responsible for central vision because photoreceptor cells that respond to light stimulation are concentrated. Age-related macular degeneration is a loss of these macular photoreceptor cells as aging progresses and causes visual impairment, and can be divided into ① wet or exudative form and ② dry or non-exudative form.
습성(wet=neovascular, exudative) 형태는 망막 밑에 맥락막 신생혈관이 자라는 경우로 항혈관내피성장인자 항체(Anti-vascular endothelial growth factor (VEGF) monoclonal antibody)를 안구내 주사하는 방법으로 치료한다. 건성(dry=atrophic) 형태는 AMD의 대부분을 차지하며 망막에 드루젠(drusen)이나 색소이상(pigmentary abnormality), 또는 망막상피의 위축(atrophy)과 같은 병변이 생긴 경우를 말한다. 건성 중 진행성 황반변성을 지도형 위축(geographic atrophy: GA)라고 하는데, 현재로서는 치료법이 전무하여 노인성 황반변성의 최대 난제인 실정이다.In the wet = neovascular, exudative form, when choroidal neovascularization grows under the retina, it is treated by intraocular injection of anti-vascular endothelial growth factor (VEGF) monoclonal antibody. The dry (atrophic) form accounts for most of AMD and refers to cases in which lesions such as drusen, pigmentary abnormalities, or atrophy of the retinal epithelium occur in the retina. Progressive macular degeneration during dryness is called geographic atrophy (GA), and currently there is no treatment, which is the biggest challenge in age-related macular degeneration.

실시예Example
실시예 1. 노인성 황반변성 동물 모델의 제조 및 후보물질 투여Example 1. Preparation of age-related macular degeneration animal model and administration of candidate substances
노인성 황반변성 동물 모델은 종래 공지된 방법(Kaneko, H. et al. DICER1 deficit induces Alu RNA toxicity in age-related macular degeneration. Nature 471, 325-330, doi:10.1038/nature09830. 2011.)과 동일하게 수행하였다. 상기 방법은 망막색소상피(Retina pigment epithelium: RPE) 내에 축적된 Alu RNA에 의해 지도형 위축을 발생시키는 방법이다. 구체적으로, GFP(green fluorescence protein) 표지된 Alu RNA 발현 렌티바이러스 벡터(Alu RNA expressing lentival vector) 0.8 X 108 genome copy(GC)/㎕ 농도로 마이크로리터 주사기 (WPI, 10 microliter syringe)에 로딩하여 준비하고, 8-10 주령 C57BL/6 마우스를 마취하고, 0.5%의 페닐에프린(phenylephrine) 및 0.5%의 트로픽아마이드(tropicamide)로 동공을 산동시켰다. 이후, 마우스의 눈꺼풀을 열고, 눈을 돌출시키고, 각막 표면에 점탄성 용액을 1방울 적용시킨 이후, 망막을 시각화 하기 위해 각막의 표면에 작은 원형 커버 슬라이드를 놓았다. 30 게이지 주사바늘로 각막 주변(Limbus) 1mm 떨어진 위치에 작은 절개를 만들고, 절개를 통해, 마이크로리터 주사기의 33 게이지 매선용 바늘(Blunt needle)을 넣고, 저항이 느껴지는 지점(망막하 공간, subretinal space)까지 주사바늘을 접근시켰다. 불필요한 조직 손상을 방지하기 위해 조심스럽고 부드럽게 바이러스를 1 ㎕ 주입한 이후, 20-30초 기다리고, 천천히 마이크로리터 주사기 바늘을 철회하였다. 망막 출혈이 없고, 망막하 수포(bleb)가 잘 형성되었는지 확인한 후 안구 표면에 항생연고를 도포하였다. 모든 실험 과정에서, 마우스의 체온을 유지하기 위해 온열 패드 위에서 실험을 수행하였다. 2주 후, 마우스로부터 안구 시료를 수득하여 망막색소상피 전체 봉입 면역염색(RPE whole mount immunostatining)을 수행하였다. Age-related macular degeneration animal model is the same as the previously known method (Kaneko, H. et al. DICER1 deficit induces Alu RNA toxicity in age-related macular degeneration. Nature 471, 325-330, doi:10.1038/nature09830. 2011.) performed. This method is a method of generating geographic atrophy by Alu RNA accumulated in retinal pigment epithelium (RPE). Specifically, GFP (green fluorescence protein)-labeled Alu RNA expressing lentival vector (Alu RNA expressing lentival vector) was loaded into a microliter syringe (WPI, 10 microliter syringe) at a concentration of 0.8 X 10 8 genome copy (GC)/μl Prepared, 8-10 week old C57BL/6 mice were anesthetized and pupil dilated with 0.5% phenylephrine and 0.5% tropicamide. After that, the eyelids of the mouse were opened, the eyes were protruded, and a drop of the viscoelastic solution was applied to the surface of the cornea, and then a small circular cover slide was placed on the surface of the cornea to visualize the retina. A small incision is made with a 30 gauge injection needle at a location 1 mm away from the limbus, and a 33 gauge blunt needle of a microliter syringe is inserted through the incision, and a point where resistance is felt (subretinal space) ), the needle was approached. After injecting 1 μl of virus carefully and gently to avoid unnecessary tissue damage, wait 20-30 seconds and slowly withdraw the microliter syringe needle. After confirming that there was no retinal hemorrhage and that subretinal blisters were well formed, antibiotic ointment was applied to the ocular surface. In all experimental procedures, the experiments were performed on a heating pad to maintain the body temperature of the mice. After 2 weeks, eye samples were obtained from the mice and RPE whole mount immunostatining was performed.
한편, 바이러스를 이용한 방법 이외에 화학적 방법의 노인성 황반변성 동물 모델을 추가로 제조하였다. 이를 위해서 상기와 동일하게 8-10 주령 C57BL/6 마우스를 준비하고, 요오드산 나트륨(Sodium iodate, NAIO3)을 20mg/Kg 농도로 꼬리 정맥을 통해 혈관내 주사하였다. 6일 후에, 망막 전위도(Electroretinogram: ERG)를 시행하고, 마우스로부터 안구 시료를 수득하여 망막색소상피 전체 봉입 면역염색(RPE whole mount immunostatining)을 수행하였다.On the other hand, in addition to the method using a virus, an animal model for age-related macular degeneration using a chemical method was additionally prepared. To this end, 8-10 week-old C57BL/6 mice were prepared in the same manner as above, and sodium iodate (NAIO 3 ) was injected intravascularly through the tail vein at a concentration of 20 mg/Kg. After 6 days, an electroretinogram (ERG) was performed, and eye samples were obtained from mice, and RPE whole mount immunostatining was performed.
노인성 황반변성 치료용 후보물질은 하기 표 1의 화합물을 이용하였으며, 상기 두 종류의 동물 모델을 제조하기 위한 렌티바이러스 또는 요오드산 나트륨을 투여하기 3일 전부터 안구 시료를 수득하는 날까지 1000mg/Kg/day의 농도로 매일 복강내 주사(Intraperitoneal injection)하였다.Candidates for the treatment of age-related macular degeneration used the compounds in Table 1 below, and from 3 days before administration of lentivirus or sodium iodate for preparing the above two types of animal models to the day of obtaining eye samples, 1000 mg/Kg/ It was intraperitoneal injection every day at the concentration of day.

망막상피세포 형태 확인을 위한 망막세포 염색은 하기의 순서로 진행하였다. 먼저, 수득한 안구 시료를 1% 파라포름알데하이드(paraformaldehyde)로 1시간 동안 고정하고, 근육(Muscle), 각막(Cornea), 수정체(Lens), 및 신경망막세포(Neural retina)를 제거한 후, Sclera/Choroid/RPE complex를 방사상(radial)으로 총 8개로 절편하였다. 각 절편 조직을 5%의 소혈청 알부민(bovine serum albumin), 2%의 NDS(normal donkey serum), 및 0.3%의 트리톤 X-100(Triton™ X-100)이 포함된 인산완충생리식염수 (Phosphate-buffered saline) 용액에서 1시간 동안 블럭(blocking)하고, 세척한 후, 4℃에서 항 ZO-1 항체로 오버나잇 반응시켰다(overnight incubation). 이후 3회 세척하고, 실온에서 2차 항체와 1시간 반응시킨 후, 다시 세척하고, 조직을 슬라이드에 도말한 후 봉입하였다. 이를 형광현미경으로 관찰하였다. Retinal cell staining for confirmation of retinal epithelial cell morphology was performed in the following order. First, the obtained eye sample was fixed with 1% paraformaldehyde for 1 hour, and after removing the muscle, cornea, lens, and neural retina, Sclera The /Choroid/RPE complex was radially sectioned into eight pieces. Each tissue section was prepared in Phosphate buffered saline containing 5% bovine serum albumin, 2% NDS (normal donkey serum), and 0.3% Triton™ X-100. -buffered saline) solution for 1 hour after blocking, washing, and overnight reaction with anti-ZO-1 antibody at 4°C (overnight incubation). Thereafter, the cells were washed three times, reacted with the secondary antibody at room temperature for 1 hour, washed again, and the tissues were smeared on slides and then embedded. This was observed with a fluorescence microscope.

실험 결과, 화합물을 투여하지 않은 대조군(Alu RNA)의 경우 전형적인 노인성 황반변성의 지도형 위축(geographic atrophy)을 나타내었다. 화학식 1을 투여(Alu RNA + NAM treatment)한 경우 망막상피세포의 크기 증가가 관찰되나, 대조군(Alu RNA)에 비하여는 망막상피세포의 크기가 확연히 작았다. 화학식 2를 투여(Alu RNA + NMN treatment)한 경우에는 망막상피세포의 퇴화가 관찰되지 않고, 정상 망막상피세포에 가까운 구조를 보였으며, 화학식 3을 투여(Alu RNA + NR treatment)한 경우에는 소수의 망막상피세포에서 약간의 크기 증가가 관찰되었으나, 전체적으로는 정상 망막상피세포에 가까운 구조를 보였다. 상기 결과로부터 렌티바이러스를 이용한 동물 모델에서 망막상피세포 퇴화의 구조적 회복 정도는 화학식 2(NMN) > 화학식 3(NR) > 화학식 1(NAM)의 순서로 치료 효과가 현저한 것을 알 수 있었다.As a result of the experiment, the control group (Alu RNA) to which the compound was not administered showed typical geographic atrophy of age-related macular degeneration. When Formula 1 was administered (Alu RNA + NAM treatment), an increase in the size of retinal epithelial cells was observed, but the size of retinal epithelial cells was significantly smaller than that of the control group (Alu RNA). When Formula 2 was administered (Alu RNA + NMN treatment), retinal epithelial cell degeneration was not observed, and a structure close to normal retinal epithelial cells was shown, and when Formula 3 was administered (Alu RNA + NR treatment), a small number of Although a slight increase in size was observed in the retinal epithelial cells of , the overall structure was close to that of normal retinal epithelial cells. From the above results, it was found that the degree of structural recovery of degeneration of retinal epithelial cells in an animal model using lentivirus was in the order of Chemical Formula 2 (NMN) > Chemical Formula 3 (NR) > Chemical Formula 1 (NAM), and the therapeutic effect was remarkable.

노인성 황반변성(age-related macular degeneration: AMD)은 나이가 들면서 망막의 황반부에 여러 가지 변화가 동반되어 생기는 질병이다. 나이가 증가함에 따라 발생율이 증가하며, 선진국에서는 성인 실명 원인 1위 질환으로 전세계적으로 약 2억명 정도의 환자가 있는 것으로 알려져 있다. 그러나 AMD의 대부분을 차지하는 건성 중 진행성 황반변성을 지도형 위축(geographic atrophy: GA)라고 하는데, 현재로서는 치료법이 전무하여 노인성 황반변성의 최대 난제인 실정이다.Age-related macular degeneration (AMD) is a disease caused by various changes in the macular area of the retina with aging. The incidence increases with age, and it is known that there are about 200 million patients worldwide as the number one cause of adult blindness in developed countries. However, progressive macular degeneration, which accounts for most of AMD, is called geographic atrophy (GA), and currently there is no treatment, which is the biggest challenge in age-related macular degeneration.
본 발명의 약학조성물은 습성뿐만 아니라 치료법이 전무한 건성의 노인성 황반변성에서도 매우 현저한 치료 효과를 발휘하였으므로, 의료 분야에서 크게 이용될 수 있을 것으로 기대된다.The pharmaceutical composition of the present invention is expected to be widely used in the medical field because it exhibited a very remarkable therapeutic effect not only in wet but also in dry age-related macular degeneration for which there is no treatment.
