Description
본 발명은 벤조티아졸 및 벤즈이미다졸 화합물, 또는 약학적으로 허용 가능한 염 및 이를 유효성분으로 포함하는 SIRTUIN 7 단백질(이하, 'SIRT7'라 함) 관련 질환의 예방 또는 치료용 약학적 조성물에 관한 것이다.
SIRTUIN 단백질(이하, 'SIRT'로 약기함)은 현재까지 SIRT1부터 SIRT7까지 총 7종이 밝혀져 있으며, 노화, 대사질환 및 유전자의 안정성 등에 관여하는 것으로 보고되었다. SIRT7은 핵인과 핵질에 존재하는 것으로 밝혀졌으며(Kiran et al., FEBS J, 2013), 세포 스트레스와 관련하여 중요한 역할을 하는 것으로 보고되었다.
일 예로, SIRT7 과발현시 촉매활성과는 무관하게 HIF-1α의 발현이 감소하고, siRNA 처리시에는 HIF-1α의 발현이 증가하는 것으로 관찰되어(Hubbi et al., J Biol Chem, 2013) SIRT7은 저산소증에 관여하는 것으로 보고되었다.
또한, SIRT7은 저혈당 스트레스와 관련이 있으며, 그 예로, 저혈당 조건이나 AMPK 활성 작용제인 AICAR 처리시 SIRT7이 핵인에서 핵질로 이동하며, 이는 핵인에서 PAF53과의 결합을 감소시켜 rDNA 전사 과정을 억제하는 것으로 보이며, 이로써 에너지 고갈 상태에 대응하는 시스템을 갖추는 것으로 해석된다(Chen et al., MolCell, 2013).
또한, 소포체(endoplasmic reticulum)의 스트레스 발생시 SIRT7의 mRNA가 증가하고 이는 소포체 스트레스 반응 단백질인 ribosomal protein 유전자 (RPS20) 등의 promoter 앞에서 Myc 활성을 억제함으로써 이러한 유전자의 전사과정을 감소시키며, 따라서 소포체의 스트레스를 억제하는 것으로 보고되었다(Shin et al., Cell Rep, 2013).
또 다른 예로, SIRT7은 노화에 관여하는데, 그 예로, SIRT7 knock-out 마우스에서 수명이 줄고(Vakhrusheva et al., Circ Res,2008) 노화 관련 청력 상실 (Ryu et al., Cell Metabolism, 2014)이 보고되었으며, 노화 쥐 모델(Lee et al., Proteomics, 2014) 및 노화 마우스 모델의 간세포(Ghiraldini et al., Mol BiolCell, 2013)에서 SIRT7의 발현이 줄어들어 있음이 관찰되었다. SIRT7에 의한 NPM1의 탈아세틸화는 노화를 억제하는데 기여할 것으로 본다(Lee et al., Proteomics, 2014).
또한, SIRT7은 DNA 손상 반응에 관여하며, 그 예로, SIRT7 knock-out MEF가 wild-type보다 ac-p53이 높음으로써 adriamycin이나 과산화수소에 의한 세포자멸에 더 민감하고(Vakhrusheva etal., J Physiol Pharmacol, 2008; Vakhrusheva et al., Cir Res, 2008), SIRT7 과발현시 paraquat 처리 후 homologous recombination 효율을 높이는 것을 관찰하였다(Mao et al., Science, 2011). SIRT7 과발현시 doxorubicin에 의해 유도되는 세포자멸이나 세포 노화가 p38 및 JNK 활성을 막음으로써 감소함이 발견되었다(Kiran et al., Exp Cell Res, 2014).
또한, SIRT7은 암과의 관련성이 보고된 바 있다. 일 예로. SIRT7은 H3K18의 탈아세틸화를 매개함으로써 tumor suppressor 유전자의 발현을 억제하고(Barber et al., Nature, 2012), mir-125a-5p 및 mir-125b에 의해 조절 받는 SIRT7 발현 증가시 간암세포의 성장을 증대시키는 것으로 보고되었다(Kim et al., Hepatology, 2013). ㄸ또한, 갑상선암 및 유방암에서 SIRT7의 발현량이 증가됨이 관찰되었다(de Nigris et al., Br J Cancer, 2002; Frye, Br J Cancer, 2002; Ashraf et al., Br J Cancer, 2006).
따라서, SIRT7 활성을 저해하는 화합물 또는 약제학적으로 허용 가능한 그의 염은 SIRT7과 관련된 질환의 치료 또는 예방에 사용될 수 있을 것으로 기대된다.
본 발명의 목적은 SIRTUIN 7 단백질(이하, 'SIRT7'라 함) 저해활성을 나타내는 벤조티아졸 유도체 또는 벤즈이미다졸 유도체, 또는 이의 약학적으로 허용 가능한 염을 제공하는 것이다.
본 발명의 또 다른 목적은 SIRT7 저해활성을 나타내는 벤조티아졸 유도체 또는 벤즈이미다졸 유도체, 또는 이의 약학적으로 허용 가능한 염을 포함하는 SIRT7 관련 질환의 예방 또는 치료용 약학 조성물을 제공하는 것이다.

실험예 2: Sirt7 저해제 화합물의 암세포 증식 억제 효과
KRAS는 RAS/MAPK pathway 중 한 부분으로 이 signal은 세포 성장과 증식을 촉진하여 발암 과정에 기여한다. KRAS의 돌연변이는 고형암의 약 20%에서 발견되고 주로 췌장, 대장, 폐암에서 흔히 발견된다. Sirt7이 p-ERK, p-MEK의 upregulation을 통하여 MAPK 활성을 증가시켜 대장암을 증가시킨다는 보고가 있다. 따라서 본 실험에서는 사람의 대장암 세포인 COLO320DM(KRAS wild-type), SW480(KRAS mutant) 세포를 대상으로 하여 본 발명 화합물들의 암세포 증식 억제 활성을 평가하였다.
세포 증식은 CCK-8 (Cell counting kit: Dojindo사 Cat. No. CK04)을 사용하여 세포독성을 측정하는 것으로 살아있는 세포의 탈수소효소의 활성에 따른 오렌지 색상의 형성 여부를 450 nm 흡광도를 측정하였다. COLO320DM, SW480 세포를 96 well plate (BD Falcon, Cat. No. 353072)에 well 당 3,000개로 seeding하고 24시간 뒤 선별된 각 억제제 화합물을 처리하였으며, 2일 간격으로 배지를 교환해주며 억제제 화합물을 함께 처리하는 방법으로 총 4일간 수행하였다. 세포 증식은 CCK-8을 well 당 10 μL 처리하고 30분간 37℃에서 반응시킨 후 450 nm 파장에서 microplate reader (Molecular Device, spectramax i3)로 측정하였다.
비교화합물로는 Biochem Biophys Res Commun. 2019;508:451-457에 보고된 Sirt7 저해제를 합성하여 사용하였다. 이하에서, 97491은 상기 비교화합물을 나타낸다.

실험예 3: Lactate dehydrogenase (LDH) 세포독성 실험
LDH (Lactose dehydrogenase, 젖산탈수소효소)는 세포질에 존재하는 효소로 통상 세포막을 통과하지 않으나 세포막이 손상되면 세포 외부 즉 배지 중으로 방출된다. 방출된 LDH를 측정하여 화합물의 독성 여부를 판단한다. COLO320DM, SW480 세포에 비교화합물(97491), 본 발명 화합물 1-37을 100 μM, 500μM 고농도로 처리하였다.
Thermo사의 Cat. No. 88953 LDH Cytotoxicity assay kit 사용하였다. 96 well plate에 20,000cell을 seeding하고 24시간 배양 후 100 μM, 500 μM 화합물을 처리하였다. 48시간 후 화합물을 처리한 배양상등액 50 μL를 새로운 96 well plate에 옮겨 담고 kit 내 제공한 substrate mix buffer 50 μL를 추가하여 빛을 차단하여 상온에서 30분간 반응시킨다. 추가로 Stop solution 50 μL를 추가한 후 마이크로플레이트 리더(microplate reader, Molecular Device, spectramax i3)로 490 nm에서 흡광도 측정하였다.
그 결과, 도 2(a)를 참조하면, COLO320DM 세포에서 세포막을 모두 손상시킨 positive control에 비하여 비교화합물(97491) 100 μM 51.9%, 비교화합물(97491) 500μM 59.2%, 본 발명 화합물 1-37 100 μM 62.1%, 본 발명 화합물 1-37 500μM 62.0%의 세포독성을 보였다. SW480 세포에서 세포막을 모두 손상시킨 positive control에 비하여 비교화합물(97491) 100 μM 13.4%, 비교화합물(97491) 500μM 46.7%, 본 발명 화합물 1-37 100 μM 14.8%, 본 발명 화합물 1-37 500μM 45.1%의 세포독성을 보임을 확인하였다.

실험예 4: in vivo 유효성 평가
이종이식(Xenograft) 종양 마우스에 발명 화합물을 투여하여 종양 억제 in vivo 유효성을 측정하였다. BALB/C-nu female 5주령 마우스를 도입하였다. 사람의 대장암 세포인 COLO320DM, SW480 세포를 trypsin을 사용하여 배양플라스크에서 분리하여 1×108 cell/ml의 농도로 준비하였다. Matrigel (Gibco사, Cat. No. A14133-02)와 1:1의 비율로 혼합하여 5주령이 된 마우스의 등 측면에 100 μL 피하로 주사하였다. 2주 후 마우스 종양의 부피가 100 mm3 되었을 때 화합물을 주 5회 경구투여 시작하였다. (Day 0) 이후 3주 동안 실시하였다.
0.1% Carboxylmethyl cellulose (CMC), 0.2% tween 80 용액에 화합물을 2 mg/ml, 4 mg/ml, 8 mg/ml의 농도로 녹여 100 ul를 경구투여하여 10 mpk, 20 mpk, 40 mpk의 농도가 되도록 하였다. 음성대조군 그룹에는 동일한 투여경로와 투여횟수에 따라 화합물 대신에 0.1% Carboxylmethyl cellulose, 0.2% tween 80 용액을 투여하였다. 각 실험군 당 6마리의 마우스를 사용하였다(도 3). 종양의 크기는 장축(length, L)과 단축(width, W)을 3일에 한 번씩 측정하였고 종양의 부피(mm3)는 (L×W×W)/2로 계산하여 각 그룹의 평균을 산출하였다. 통계처리는 GraphPad Prism6 프로그램을 사용하였으며 p값이 0.05 미만인 경우를 유의성이 있는 것으로 간주하였다.
흉선이 제거되어 T세포가 감소되어 면역계가 억제된 5주령 된 누드마우스를 도입하여 인간 대장암 세포주인 COLO320DM, SW480을 피하에 주사하였다. Sirt7 저해제인 본 발명 화합물 1-37(10 mpk, 20 mpk, 40 mpk), 1-105(100 mpk), 1-106(100 mpk)을 3주간 경구투여한 결과, 도 4 내지 도 11을 참조하면, 시약을 녹인 용액만 먹인 대조군에 비하여 두 세포주 모두 tumor 크기가 감소하였으며, 1차 및 2차 in vivo 실험 결과는 동일한 결과를 보였다. COLO320DM을 주입한 마우스군에서 발명 화합물 1-37을 40 mpk를 경구투여했을 때 가장 유의성 있는 tumor 생성 억제 효과를 보였고 농도 의존적 tumor 생성 억제 효과를 보였다.
