대사 증후군, 당뇨 및 비알코올성 지방간염(NASH)은 선천적 또는 후천적 요인에 의한 세포 대사 균형의 붕괴와 관련이 있다 (Nat. Med. 2018, 24, 908-922). PPAR (peroxisome proliferator activated receptor)은 핵 전사인자로서 대사 항상성 유지에서 중요한 역할을 한다 (Expert Opin. Pharmacother. 2014, 15, 493-503). PPAR은 세포의 지방산 수준에 대한 반응으로 세포 대사에 필요한 다양한 유전자의 전사를 활성화시킬 수 있다. 포유류 세포에서는 PPAR의 세 가지 아형으로 PPARα, PPARγ, 그리고 PPARδ가 알려져 있는데, 이들은 조직에 따라 다른 발현 양상을 보인다 (Trends Endocrinol. Metab. 2012, 23, 351-363). 예를 들어, PPARγ는 지방 조직에서 주로 발현되며, PPARδ는 주로 골격근에서 관찰이 된다. PPAR은 RXR (retinoid X receptor)과 이질이합체(heterodimer)를 형성하여 PPRE (peroxisome proliferator response element)에 결합하며, 이 과정은 대사와 관련된 유전자의 전사에 필수적이다. PPAR은 대사 항상성 조절에 중요한 역할을 하기 때문에, 그 약물학적 리간드들은 다양한 대사성 질환의 치료를 목적으로 개발되어 왔다 (Chem. Rev. 2011, 111, 6321-6340). 하지만, PPARγ 또는 PPARδ에 특이적인 효능제는 간 독성이나 심혈관 부작용과 같은 안전성 문제를 일으켜 왔다 (Hepatology 2005, 41, 237-246; Arch. Intern. Med. 2010, 170, 1191-1201; BMJ 2011, 342, d1309). 이러한 안전성 문제를 해결하기 위해, 균형 잡힌 PPAR 활성화를 통해 심각한 부작용을 줄일 수 있을 것이라는 기대로 PPAR 이중 또는 삼중 조절자가 제안되고 개발되어 왔다 (Lancet 2009, 374, 126-135; J. Med. Chem. 2018, 61, 2246-2265; ACS Med. Chem. Lett. 2019, 10, 545-551). 특히, PPARδ가 과발현 또는 전사 활성이 증가된 경우 PPARγ의 활성을 저해하여, PPARδ가 PPARγ 기능의 조절자 역할을 할 수 있음이 보고된 바 있다 (Proc. Natl. Acad. Sci. U.S.A. 2002, 99, 2613-2618).Metabolic syndrome, diabetes, and nonalcoholic steatohepatitis (NASH) are associated with disruption of cellular metabolic balance due to congenital or acquired factors (Nat. Med. 2018, 24, 908-922). PPAR (peroxisome proliferator activated receptor) is a nuclear transcription factor and plays an important role in maintaining metabolic homeostasis (Expert Opin. Pharmacother. 2014, 15, 493-503). PPARs can activate the transcription of various genes required for cellular metabolism in response to cellular fatty acid levels. In mammalian cells, PPARα, PPARγ, and PPARδ are known as three subtypes of PPAR, and they show different expression patterns depending on the tissue (Trends Endocrinol. Metab. 2012, 23, 351-363). For example, PPARγ is mainly expressed in adipose tissue, and PPARδ is mainly observed in skeletal muscle. PPAR forms a heterodimer with RXR (retinoid X receptor) and binds to PPRE (peroxisome proliferator response element), which is essential for transcription of metabolic genes. Since PPAR plays an important role in the regulation of metabolic homeostasis, its pharmacological ligands have been developed for the treatment of various metabolic diseases (Chem. Rev. 2011, 111, 6321-6340). However, agonists specific for PPARγ or PPARδ have caused safety problems such as liver toxicity or cardiovascular side effects (Hepatology 2005, 41, 237-246; Arch. Intern. Med. 2010, 170, 1191-1201; BMJ 2011, 342, d1309). To solve this safety problem, PPAR double or triple modulators have been proposed and developed with the expectation that serious side effects can be reduced through balanced PPAR activation (Lancet 2009, 374, 126-135; J. Med. Chem. 2018, 61, 2246-2265; ACS Med. Chem. Lett. 2019, 10, 545-551). In particular, it has been reported that PPARδ inhibits the activity of PPARγ when overexpression or transcriptional activity is increased, so that PPARδ can act as a regulator of PPARγ function (Proc. Natl. Acad. Sci. U.S.A. 2002, 99, 2613-2618).

본 발명자들은 종래의 연구를 통해 4'-싸이오구아노신 유도체를 A3 아데노신 수용체(adenosine receptor; AR) 조절자, PPARγ 부분 효능제, 그리고 PPARδ 길항제의 다중약리 프로파일을 갖는 리간드로 보고한 바 있다 (J. Med. Chem. 2017, 60, 7459-7475). 이 리간드들은 인간 골수 중간엽 줄기 세포 (human bone marrow mesenchymal stem cell; hBM-MSC)의 지방세포 분화 및 지질형성 모델에 기반한 표현형 분석법을 통해 아디포넥틴 분비 및 지질 축적을 증가시킴을 확인하였다 (Biochem. Pharmacol. 2012, 83, 661-670, Biochem. Pharmacol. 2009, 77, 1835-1844). 아디포넥틴은 지방세포에서 주요하게 생산되는 아디포사이토카인 (adipocytokine)으로서 지방 조직과 다른 대사 관련 조직 간의 신호전달에서 중요한 역할을 하는 통합적 조절자로서 주목을 받아왔다 (J. Mol. Cell. Biol. 2016, 8, 93-100; Acta Physiol. 2014, 210, 733-753). 따라서, 아디포넥틴은 다양한 대사성 질환에서 진단적 바이오마커로서 사용되기도 하며, 재조합 아디포넥틴이 인간 대사성 질환의 다양한 동물 모델에서 치료적 효과를 보여주기도 하였다 (Trends Pharmacol. Sci. 2009, 30, 234-239). 또한, 아디포넥틴은 혈중 포도당 수준을 조절하고 지방산 분해에 관여하여 인슐린 저항성을 개선시킬 뿐만 아니라, 항죽종형성 효과나 항염증 효과를 갖고 있는 것으로 알려져 있다. 따라서, 아디포넥틴은 제2형 당뇨, 죽상동맥경화 및 심혈관 질환을 포함한 다양한 질환에서 치료적 잠재력을 가지고 있다 (Nat. Med. 2001, 7, 941-946; Arterioscler., Thromb., Vasc. Biol. 2004, 24, 29-33; Diabetes 2007, 56, 1198-1209).The present inventors reported a 4'-thioguanosine derivative as a ligand having a multipharmacological profile of an A 3 adenosine receptor (AR) modulator, a partial PPARγ agonist, and a PPARδ antagonist through a prior study. (J. Med. Chem. 2017, 60, 7459-7475). It was confirmed that these ligands increase adiponectin secretion and lipid accumulation through a phenotypic analysis based on the adipocyte differentiation and lipogenesis model of human bone marrow mesenchymal stem cell (hBM-MSC) (Biochem. Pharmacol). 2012, 83, 661-670, Biochem. Pharmacol. 2009, 77, 1835-1844). Adiponectin is an adipocytokine mainly produced in adipocytes and has been attracting attention as an integrative regulator that plays an important role in signaling between adipose tissue and other metabolic-related tissues (J. Mol. Cell. Biol. 2016). , 8, 93-100; Acta Physiol. 2014, 210, 733-753). Therefore, adiponectin is also used as a diagnostic biomarker in various metabolic diseases, and recombinant adiponectin has also shown therapeutic effects in various animal models of human metabolic diseases (Trends Pharmacol. Sci. 2009, 30, 234-239). In addition, adiponectin is known to have an anti-atherogenic effect or an anti-inflammatory effect as well as improving insulin resistance by regulating blood glucose levels and participating in fatty acid degradation. Thus, adiponectin has therapeutic potential in various diseases including type 2 diabetes, atherosclerosis and cardiovascular disease (Nat. Med. 2001, 7, 941-946; Arterioscler., Thromb., Vasc. Biol. 2004). , 24, 29-33; Diabetes 2007, 56, 1198-1209).

이러한 배경 하에, 본 발명자들은 A3AR에 대해 결합하지 않는 1'-호모아데노신 유도체가 hBM-MSC의 지방분화 모델에서 아디포넥틴 생산을 유의하게 증가시킴을 발견하였고, 또한 이들 리간드가 PPARγ 및 PPARδ에 친화력 및 활성화 능력을 갖는지 측정한 결과, 1'-호모아데노신 유도체가 PPARγ 부분 효능제 및 PPARδ 길항제 활성을 통해 지방세포에서 아디포넥틴 분비를 증가시키고 이에 따라 다양한 대사성 질환을 포함한 저아디포넥틴혈증과 연관된 질환을 효과적으로 예방 및 치료할 수 있음을 확인하고 본 발명을 완성하였다.Against this background, the present inventors have found that 1'-homoadenosine derivatives that do not bind to A 3 AR significantly increase adiponectin production in the adipogenesis model of hBM-MSC, and also that these ligands have affinity for PPARγ and PPARδ. And as a result of measuring whether it has an activation ability, the 1'-homoadenosine derivative increases adiponectin secretion from adipocytes through PPARγ partial agonist and PPARδ antagonist activity, thereby effectively preventing diseases associated with hypoadiponectinemia, including various metabolic diseases. And it was confirmed that it can be treated, and completed the present invention.

따라서, 본 발명의 목적은 A3 아데노신 수용체에 결합하지 않고 동시에 PPARγ 부분 효능제 활성 및 PPARδ 길항제 활성을 갖는 신규한 1'-호모아데노신 유도체를 제공하는 것이다.Accordingly, it is an object of the present invention to provide novel 1'-homoadenosine derivatives that do not bind to the A 3 adenosine receptor and simultaneously have PPARγ partial agonist activity and PPARδ antagonist activity.

본 발명의 약학 조성물에 있어서, 상기 저아디포넥틴혈증 관련 질환은 암 또는 대사성 질환 등일 수 있으나, 이에 제한되지 않는다. 상기 대사성 질환은 비만, 당뇨, 비알코올성 지방간염 (Nonalcoholic steatohepatitis, NASH), 대사 증후군, 고혈압, 고지혈증, 심혈관 질환 및 죽상동맥경화증으로 이루어진 군으로부터 선택되는 어느 하나 이상을 포함하는 것일 수 있으나, 이에 한정되지 않는다.In the pharmaceutical composition of the present invention, the hypoadiponectinemia-related disease may be cancer or a metabolic disease, but is not limited thereto. The metabolic disease may include any one or more selected from the group consisting of obesity, diabetes, nonalcoholic steatohepatitis (NASH), metabolic syndrome, hypertension, hyperlipidemia, cardiovascular disease, and atherosclerosis, but limited thereto doesn't happen

본 발명의 화합물은 대사 증후군 및 암과 같은 저아디포넥틴혈증과 관련된 다양한 질병을 치료할 수 있는 잠재력을 갖는다. 아디포넥틴의 외인성 치료는 죽상동맥경화증 및 비알코올성 지방간 질환에 대한 동물 모델에서 병원성 표현형을 개선한 것으로 보고 되었다 (Diabetes 2010, 59, 791-799.; J. Clin. Invest. 2003, 112, 91-100.). 따라서, PPARγ/δ 이중 조절자에 의한 아디포넥틴 수준의 상승 조절은 이러한 대사성 질환에 대한 치료적 이점을 제공할 수 있다. 흥미롭게도, PPARγ 부분 효능제와 PPARδ 길항제는 시너지 효과로 암 치료에 기여할 수 있다. PPAR의 활성화는 암세포의 세포 사멸을 유도한 것으로 보고되었다 (Br. J. Pharmacol. 2011, 164, 68-82.; Eur. J. Med. Chem. 2017, 127, 379-397.). 구체적인 PPARδ 효능제인 GW501516이 동물 모델에서 종양을 유의하게 유도하였기 때문에 (Expert Opin. Pharmacother. 2014, 15, 493-503; Metab. 2015, 26, 595-607.), PPARδ 길항제는 항증식 치료제의 신약으로 제안되어 왔다 (Cancer Biol. Ther. 2009, 8, 1262-1264.). The compounds of the present invention have the potential to treat various diseases associated with hypoadiponectinemia, such as metabolic syndrome and cancer. Exogenous treatment of adiponectin has been reported to ameliorate the pathogenic phenotype in animal models for atherosclerosis and nonalcoholic fatty liver disease ( Diabetes 2010 , 59 , 791-799.; J. Clin. Invest. 2003 , 112 , 91-100). .). Thus, upregulation of adiponectin levels by PPARγ/δ dual modulators may provide a therapeutic benefit for these metabolic diseases. Interestingly, PPARγ partial agonists and PPARδ antagonists may contribute to cancer treatment synergistically. Activation of PPAR has been reported to induce apoptosis of cancer cells ( Br. J. Pharmacol. 2011 , 164 , 68-82.; Eur. J. Med. Chem. 2017 , 127 , 379-397.). Because GW501516, a specific PPARδ agonist, significantly induced tumors in animal models ( Expert Opin. Pharmacother. 2014 , 15 , 493-503; Metab. 2015, 26, 595-607.), PPARδ antagonists are new drugs for antiproliferative therapy. has been proposed as ( Cancer Biol. Ther. 2009 , 8 , 1262-1264.).

최근에는 PPARδ 길항제가 트랜스제닉 동물 모델에서 건선과 유사한 병원성 결과를 약화시키는데 효과적이라고 보고되었다 (PLoS One 2012, 7, e37097.). 건선은 과증식성 피부 질환이므로 PPARδ 길항제의 항건선 활성을 합리적으로 기대할 수 있다.Recently, it has been reported that PPARδ antagonists are effective in attenuating psoriasis-like pathogenic outcomes in transgenic animal models ( PLoS One 2012 , 7 , e37097.). Since psoriasis is a hyperproliferative skin disease, the anti-psoriatic activity of PPARδ antagonists can be reasonably expected.

After reduction of 5 with sodium borohydride, the resulting diol was treated with mesyl chloride to obtain dimesylate 6 . 6 was heated with sodium sulfide in DMF to yield 7 of 4-thiosugar. Regioselective hydrolysis of 5,6-acetonide of 7 with 60% AcOH yielded 5,6-diol 8 . The aldehyde was produced by oxidative cleavage of 8 with Pb(OAc) 4 at 0° C., and the primary alcohol 9 was produced by reduction with sodium borohydride without purification. It was noted that oxidative cleavage with excess Pb(OAc) 4 at room temperature produced 1-acetate directly, which was formed through further oxidation of 8 with acid followed by subsequent oxidative decarboxylation. 9 was treated with phosphorus oxychloride to give the glycosyl donor 10 .

등배전자성 근거를 바탕으로, 반응식 5에 나타난 바와 같이, L-리보스로부터 상응하는 4’-옥소 유도체 4m-4t를 디자인하고 합성하였다. L-리보스는 산성 조건에서 아세톤으로 처리하여 2,3-아세토나이드 20으로 변환하였다. 트리틸 (Tr)로 20의 하이드록시기를 보호한 다음 NaBH4로 환원시켜 다이올 21을 수득하였다. 21의 1차 알코올의 위치선택적 토실화 (tosylation)는 모노 토실레이트를 4-옥소 당 22로 원활하여 변환하였다. -40 ℃에서 CH2Cl2에 용해된 Et2AlCl로 처리하여 22의 Tr기를 제거하여 글리코실 공여자 23을 생성하였다. 23을 2,6-디클로로퓨린 및 6-클로로퓨린과 미쯔노부 축합하여 각각 2,6-디클로로퓨린 뉴클레오사이드 24와 6-클로로퓨린 뉴클레오사이드 25를 수득하였다. 2425를 3-할로벤질아민으로 처리한 후, 아세토나이드 탈보호하여 절단된 1’-동족체화 4’-옥소아데노신 유도체 4m 내지 4t를 생성하였다.Based on the isogenetic basis, as shown in Scheme 5, the corresponding 4'-oxo derivative 4m-4t was designed and synthesized from L-ribose. L-ribose was converted to 2,3-acetonide 20 by treatment with acetone under acidic conditions. The hydroxyl group of 20 was protected with trityl (Tr) and then reduced with NaBH 4 to obtain diol 21 . Regioselective tosylation of the primary alcohol of 21 smoothly converted mono tosylate to 22 4-oxo sugar. The Tr group of 22 was removed by treatment with Et 2 AlCl dissolved in CH 2 Cl 2 at -40 °C to give the glycosyl donor 23 . 23 was condensed with 2,6-dichloropurine and 6-chloropurine by Mitsunobu to obtain 2,6-dichloropurine nucleoside 24 and 6-chloropurine nucleoside 25 , respectively. 24 and 25 were treated with 3-halobenzylamine, followed by acetonide deprotection to yield 4m to 4t of cleaved 1'-homologized 4'-oxoadenosine derivatives.

LJ-1251과 화합물 4의 하이드록시기와 His272의 수소 사이의 거리를 측정하였을 때, 화합물 4의 하이드록시기는 수소결합을 형성하기에는 먼 거리에 위치하는 것으로 화합물 4의 A3AR에 대한 결합 능력 소실을 설명할 수 있었다 (도 5의 C 및 D 참조). 도 5의 E에 나타낸 바와 같이 PPARγ 리간드 결합 부위 내에서 화합물 4는 로지글리타존과 유사한 양상으로 결합하는 것을 확인할 수 있었다. 도 5의 F 및 G에서 확인되는 바와 같이 화합물 4는 PPARδ 리간드 결합 부위 내에서 Lys229 및 Gln230 잔기와 2-Cl 치환기를 이용해 상호작용할 수 있었지만, 화합물 8은 부피가 큰 2-(1-프로피닐) 치환기를 가져 이러한 상호작용을 할 수 없는 것으로 화합물 4가 PPARγ/δ 이중 조절자로 작용하는 반면, 화합물 8은 PPARγ에만 결합 활성이 있는 것을 설명할 수 있었다.As shown in FIG. 5A and FIG. 5B , in the optimal binding conformation, LJ-1251 was able to interact with Thr94, Phe168, Ser271 and His272 amino acid residues, but compound 4 showed Thr94 and Thr94 and It failed to interact with the His272 amino acid residue. When the distance between LJ-1251 and the hydroxyl group of Compound 4 and the hydrogen of His272 was measured, the hydroxyl group of Compound 4 was located far enough to form a hydrogen bond, suggesting that the loss of binding ability to A 3 AR of Compound 4 was could be explained (see FIG. 5C and D). As shown in FIG. 5E , it was confirmed that Compound 4 binds in a similar manner to rosiglitazone within the PPARγ ligand binding site. As shown in F and G of Figure 5, compound 4 was able to interact with Lys229 and Gln230 residues within the PPARδ ligand binding site using a 2-Cl substituent, but compound 8 was a bulky 2-(1-propynyl) The inability to have such an interaction due to the presence of a substituent could explain that compound 4 acts as a PPARγ/δ dual modulator, whereas compound 8 has binding activity only to PPARγ.
