文献调研,根据专利文献TW201742868A(公开日2017-12-16,该文献内容也在WO2017202817A1、AU2017269871A1、US20180319807A2、US20170342082A1等文件中公开)公开内容可知:
醛基酮基还原酶族1成员C3(AKR1C3,亦被称作5型17-β-羟基类固醇去氢酶(17-β-HSD5))为酶类之醛/酮基还原酶(AKR)超家族的成员,其将类固醇激素中之醛/酮基还原成对应醇,且因此在雄激素、孕酮、雌激素及及前列腺素的代谢/活化/去活化中起重要作用。
AKR1C3具有3α-HSD(羟基类固醇去氢酶活性)、17β-HSD、20α-HSD及前列腺素(PG)F合成酶活性。其催化雌酮(弱雌激素活性)至雌二醇(强雌激素活性)之转化、孕酮(强抗雌激素活性)至20-α-羟基孕酮(弱抗雌激素活性)之转化及雄烯二酮至睾固酮之转化(LabrieF,Luu-T he V,Labrie C,et al.DHEA and Its Transformation into Androgens andEstrogens in Peripheral Target Tissues:Intracrinology[J].Frontiers inNeuroendocrinology,2001,22(3):185-212.DOI:10.1006/frne.2001.0216)。此外,AKR1C3催化PGH2至PGF2α及PGD2至11β-PGF2之转化,已知两者刺激发炎及增生。
此外,亦已展示AKR1C3使广泛范围之羰基化合物及异生物质(包括临床上投与之蒽环类霉素anthracycline)代谢(Bains O S,Grigliatti T A,Reid R E,etal.Naturally occurring variants of human aldo-keto reductases with reduced invitro metabolism of daunorubicin and doxorubicin.[J].Journal of Pharmacology&Experimental Therapeutics,2010,335(3):533-545.DOI:10.1124/jpet.110.173179;Novotna R,Wsol V,Xiong G,et al.Inactivation of the anticancer drugs doxorubicin and oracin by aldo–keto reductase(AKR)1C3[J].Toxicology Letters,2008,181(1):1-6.DOI:10.1016/j.toxlet.2008.06.858;Hofman J,Malcekova B,SkarkaA,et al.Anthracycl ine resistance mediated by reductive metabolism in cancercells:The role of aldo-keto reductase 1C3[J].Toxicology and AppliedPharmacology,2014,278(3):238-248.DOI:10.1016/j.taap.2014.04.027)。
AKR1C3与子宫内膜异位密切相关。AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病包括子宫内膜异位。
子宫内膜异位为主要雌激素相依之慢性发炎疾病,其表征为子宫腔外存在子宫内膜组织。子宫内膜异位之主要症状为慢性骨盆疼痛及低生育力。雌激素(E2)缺乏为用于药理治疗子宫内膜异位之临床上经证实之概念及基础主要作用机制。除全身雌激素含量以外,局部衍生的雌激素促进子宫内膜异位病变之发展的迹象愈来愈多。最近已描述子宫内膜异位病变之高组织内雌激素浓度,其表明在子宫内膜异位中的高局部雌激素合成(Huhtinen K,Desai R,Stahlee M,et al.Endometrial and EndometrioticConcentrations of Estrone and Estradiol Are Determined by Local MetabolismRather than Circulating Levels[J].The Journal of Clinical Endocrinology&Metabolism,2012,97(11):4228-4235.DOI:10.1210/jc.2012-1154)。因此,在子宫内膜异位病变中抑制局部E2之产生被视为用于治疗子宫内膜异位之极具吸引力的作用机制。AKR1C3很大程度上在子宫内膜异位病变中表现,且仅可在卵巢中略微可侦测到(TinaHevir N,Martinaet al.Disturbed estrogen and progesterone action inovarian endometriosis[J].Molecular&Cellular Endocrinology,2009,301(1):59-64.DOI:10.1016/j.mce.2008.07.020)。在与CYP19A1(芳香酶)协同作用时,预期AKR1C3成为子宫内膜异位病变中之局部E2产生之关键酶,从而产生促雌激素环境,藉此刺激对雌激素敏感的子宫内膜异位细胞之增生。对AKR1C3之抑制应因此使得局部组织内E2含量下降,且藉此使子宫内膜异位病变之增生减少。不预期在卵巢雌激素产生方面之效果,此系因为AKR1C3在卵巢中仅略微表现,且17βHSD1为显性卵巢羟基类固醇去氢酶。
AKR1C3亦为PGF2α合成酶,且除AKR1C3之调升之外,已展示PGF2α之含量在来自患有腹膜子宫内膜异位之女性之正位及异位子宫内膜两者中相比在来自患有卵巢子宫内膜瘤之女性之类似组织中明显更高(Sinreih,Anko M,Kene N H,et al.Expression ofAKR1B1,AKR1C3and other genes of prostaglandin F2αbiosynthesis and action inovarian endometriosis tissue and in model cell lines[J].Chemico-BiologicalInteractions,2015,234(5-6):320-331.DOI:10.1016/j.cbi.2014.11.009)。预期子宫内膜异位组织中之PGF2α造成子宫内膜异位患者的发炎、疼痛及增生,且预期在子宫内膜异位病变中表现之AKR1C3造成子宫内膜异位组织中之高局部PGF2α含量。AK R1C3抑制具有藉由局部减少子宫内膜异位组织中之E2、睪固酮及PGF2α含量来缓解子宫内膜异位患者之增生、疼痛及发炎的潜能。
AKR1C3与多囊性卵巢症候群(PCOS)密切相关。AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病包括多囊性卵巢症候群(PCOS)。
PCOS为常见内分泌病症,其影响高达10%的生殖年龄女性。其临床上与无卵性不孕症、功能不良性出血、雄激素过量、高胰岛素血症及抗胰岛素症、肥胖症及代谢症候群相关联(Fang Y.Insulin resistance and the polycystic ovary syndrome:Mechanismand implications for pathogenesis[J].Endocrine Reviews,1998,18(6):774-800.DOI:10.1210/edrv.18.6.0318)。PCOS之四个主要特征已由雄激素过量学会(AndrogenExcess Society)确认:排卵及月经功能异常、生物化学高雄激素血症、临床雄激素过多症(例如,痤疮、多毛症)及多囊性卵巢症(Azziz R,Carmina E,Dewailly D,Diamanti-Kandarakis E,Escobar-Morreale HF,Futterweit W,et al.Position statement:criteria for defining polycystic ovary syndrome as a predominantlyhyperandrogenic syndrome:an Androgen Excess Society.[J].Clin EndocrinolMetab2006;91:4237-45.DOI:10.1055/s-2003-43304)。患有PCOS的绝大部分女性会呈现雄激素过多症之临床症状,例如痤疮、多毛症或主要藉由低生育力或月经过少显现之无排卵(LegroRichard S,Brzyski Robert G,Diamond Michae P,et.al,Letrozole versusClomiphene for Infertility in the Polycystic Ovary Syndrome[J].New England Journal of Medicine,2014,371(2):119-129.DOI:10.1056/nejmoa1313517)。患有PCOS的女性易患葡萄糖不耐及代谢症候群(Taponen S,Martikainen H,Jarvelin M R.MetabolicCardio vascular Disease Risk Factors in Women With Self-Reported Symptoms ofOligomenorrhea and/or Hirsutism:Northern Finland Birth Cohort 1966Study[J].Journal of Clinical Endocrinology&Met abolism,2004,89(5):2114-8.DOI:10.1210/jc.2003-031720),具有心血管疾病相关联之风险因素及很可能增加的未来心血管事件之风险(Mani H,Levy MJ,Davies MJ,et al.Diabetes and car diovascular events inwomen with polycystic ovary syndrome;a 20-year retrospective cohort study[J].Clin Endocrinol,2013,78(6):926-934.DOI:10.1111/cen.12068)。雄激素过多症、多毛症及/或高雄激素血症为该症候群之关键组成部分,且必选用于诊断PCOS(Azziz R,Carmina E,Dew ailly D,Diamanti-Kandarakis E,Escobar-Morreale HF,Futterweit W,et al.Position statement:criteria for defining polycystic ovary syndrome as apredominantly hyperandrogenic syndrome:an Androgen Excess Society.[J].ClinEndocrinol Metab2006;91:4237-45.DOI:10.1055/s-2003-43304)。虽然血清睪固酮为高雄激素血症之生物化学评估之关键因素,但最近建议将雄烯二酮作为PCOS相关雄激素过量之更可靠标记物,此系因为雄烯二酮在PCOS女性体内高浓度循环(O’Reilly,Micha el W,Taylor A E,Crabtree N J,et al.Hyperandrogenemia predicts metabolic phenotypein poly cystic ovary syndrome:the utility of serum androstenedione[J].TheJournal of Clinical Endocrinol ogy&Metabolism,2014:jc.2013-3399.DOI:10.1210/jc.2013-3399)。PCOS在传统上已被视为卵巢病症(Franks S,Gharani N,Gilling-SmithC.Polycystic ovary syndrome:evidence for a primary disorder of ovariansteroidogenesis[J].Journal of Steroid Biochemistry and Molecular Biology,1999,69:269-272.DOI:10.1016/s0960-0760(99)00044-8)。然而,对PCOS之卵巢外及肾上腺外雄激素形成增加的关注已突显周围组织的作用,诸如脂肪雄激素形成(Quinkler M,Sinha B,Tom linson JW,Bujalska IJ,Stewart PM,Arlt W(2004)Androgen generationin adipose tissue in women with simple obesity a site-specific role for 17{beta}-hydroxysteroid dehydrogenase type5.[J].J Endocrinol,2004,183:331-342.DOI:10.1677/joe.1.05762)。AKR1C3为雄激素活化酶,已知其主要系将雄烯二酮转化成睪固酮。已描述PCOS患者之脂肪组织中之AKR1C3的调升,其指示脂肪中之ARK1C3表现明显促进PCOS患者之雄烯二酮的雄激素形成。已另外展示脂肪细胞中之AK R1C3表现藉由胰岛素明显增加,其指示在PCOS中较高的胰岛素能够藉由增加女性皮下脂肪组织中之AKR1C3活性来推进脂肪雄激素形成(O"Reilly M,Gathercole L,Capper F,et al.Effect ofinsulin on AKR1C3 expression in female adipose tissue:in-vivo and in-vitrostudy of adipose androgen generation in polycystic ovary syndrome[J].TheLancet,2015,385:S16.DOI:10.1016/S0140-6736(15)60331-2)。AKR1C3亦为PGF2α合成酶,且在用于过氧化体增生物活化受体γ(PPARg amma)之内源性配位体的形成中起抑止作用,该过氧化体增生物活化受体γ为胰岛素敏化药物之标靶(Spiegelmanet.al,Diabetes1998,47:507-514.DOI:10.2337/diabetes.47.4.507)。选择性AKR1C3抑制可提供新颖治疗标靶以减小雄激素负担及改良PCOS中之代谢表现型(O"Reilly M,Gathercole L,Capper F,et al.Effect of insulin on AKR1C3 expression in female adiposetissue:in-vivo and in-vitro study of adipose androgen generation inpolycystic ovary syndrome[J].The Lance t,2015,385:S16.DOI:10.1016/S0140-6736(15)60331-2;Du et.al,J Clin Endocrinol Metab.2009,94(7):2594-2601.DOI:10.1210/jc.2009-0139)。
AKR1C3与癌症密切相关。AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病包括癌症。
AKR1C3在大量癌症中过度表现,该等癌症包括诸如以下之彼等前列腺癌、乳癌、子宫癌、血癌、肺癌、脑癌及肾癌:子宫内膜癌(Rizner TL,Smuc T,Rupreht R,Sinkovec J,Penning TM AKR1C1 and AKR1C3 may determine progesterone and estrogen ratiosin endometrial cancer.[J].Molecular&Cellular Endocrinology,2005,248(1-2):126-135.DOI:10.1016/j.mce.2005.10.009)、肺癌(Lan Q,Mumford JL,Shen M,Demarini DM,Bonner MR,He X,Yeager M,Welch R,Chanock S,Tian L,Chapman RS,Zheng T,KeohavongP,Caporaso N,Rothman N.Oxidative damage-related genes AKR1C3 and OGG1modulate risks for lung cancer due to exposure to PAH-rich coal combustionemissions.Carcinogenesis.2004,25(11):2177–2181.DOI:10.1093/carcin/bgh240)、非霍奇金淋巴瘤(Lan Q,Zheng T,Shen M,et al.Genetic polymorphisms in theoxidative stress pathway and susceptibility to non-Hodgkin lymphoma.HumGenet.2007;121:161–168.DOI:10.1007/s00439-006-0288-9)、膀胱癌(Figueroa J D,Núria Malats,Montserrat García-Closas,et al.Bladder cancer risk and geneticvariation in AKR1C3 and other metabolizing genes[J].Carcinogenesis,2008,29(10):1955-62..DOI:10.1093/carcin/bgn163)、慢性骨髓白血病(Birtwistle J,Hayden RE,Khanim F L,et al.The aldo-keto reductase AKR1C3 contributes to 7,12-dimethylbenz(a)anthracene-3,4-dihydrodiol mediated oxidative DNA damage inmyeloid cells:Implications for leukemogenesis[J].Mutation Research,2009,662(1-2):67-74.DOI:10.1016/j.mrfmmm.2008.12.010)、肾细胞癌(Azzarello J T,Lin H K,Gherezghiher A,et al.Expression of AKR1C3 in renal cell carcinoma,papillaryurothelial carcinoma,and Wilms'tumor[J].International Journal of Clinical&Experimental Pathology,2010,3(2):147.PMID:20126582)、乳癌(Byrns M C,Duan L,LeeS H,et al.Aldo-keto reductase 1C3 expression in MCF-7 cells reveals roles insteroid hormone and prostaglandin metabolism that may explain its over-expression in breast cancer[J].J Steroid Biochem Mol Biol,2010,118(3):0-187.DOI:10.1016/j.jsbmb.2009.12.009),然而其调升与肿瘤侵袭性及攻击性通常相关(Azzarello J T,Lin H K,Gherezghiher A,et al.Expression of AKR1C3 in renalcell carcinoma,papillary urothelial carcinoma,and Wilms'tumor[J].International Journal of Clinical&Experimental Pathology,2010,3(2):147.PMID:20126582;Birtwistle J,Hayden R E,Khanim F L,et al.The aldo-keto reductaseAKR1C3 contributes to 7,12-dimethylbenz(a)anthracene-3,4-dihydrodiol mediatedoxidative DNA damage in myeloid cells:Implications for leukemogenesis[J].Mutation Research,2009,662(1-2):67-74.DOI:10.1016/j.mrfmmm.2008.12.010;Miller et.al,Aldo-keto reductase family 1memberC3(AKR1C3)is expressed inadenocarcinoma and squamous cell carcinoma but not small cell carcinoma.[J].Int.J.Clin.Exp.Path.2012,5:278-289.PMID:22670171)。AKR1C3能够直接将雌酮及孕酮分别还原成17β-雌二醇及20α-羟孕酮,藉此增强此促增生性信号(Smuc,Rizner,Expression of 17β-hydroxysteroid dehydrogenases and other estrogen-metabolizing enzymes in different cancer cell lines[J].Chem BiolInteract.2009,178:228-33.DOI:10.1016/j.cbi.2008.10.038)。
另外,AKR1C3之前列腺素F合成酶活性催化PGH2至PGF2α及PGD2至11β-PGF2α之转化,已知两者刺激发炎及增生。在缺乏AKR1C3活性之情况下,PGD2(替代转化成PGF2)自发地脱水及重排以形成抗增生性及抗发炎性PGJ2异构体,包括15d-PGJ2。
概言之,AKR1C3增加增生性PGF2异构体并减少抗增生性PGJ2产物,且因此AKR1C3具有影响激素依赖性及激素非依赖性癌症两者之可能性。在乳癌中,假定AKR1C3之作用可产生其活化导致癌细胞存活之前列腺素F2α(PTGFR)配体(Yoda T et.al,11β-Prostaglandin F2α,a bioactive metabolite catalyzed by AKR1C3,stimulatesprostaglandin F receptor and induces slug expression in breast cancer[J].MolCell Endocrinol.15;413:236-247.DOI:10.1016/j.mce.2015.07.008)。
AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病特别的包括前列腺癌。AKR1C3之高度表现已与前列腺癌恶化及攻击性相关联(Stanbrough M et.al,Increased expression of genesconverting in androgen-independent prostatecancer[J].Cancer Res2006,66:2815-25.DOI:10.1158/0008-5472.can-05-4000;Wako K,Kawasaki T,Yamana K.et al.Expression of androgen receptor through androgen-converting enzymes is associated with biological aggressiveness in prostatecancer.J Clin Pathol.2008Apr;61(4):448–54.DOI:10.1136/jcp.2007.050906)。在激素依赖性前列腺癌中,AKR1C3将雄烯二酮转化成睪固酮,其转而过度活化雄激素受体且促进肿瘤生长(Penning T M,Steckelbroeck S,Bauman D R,et al.Aldo-keto reductase(AKR)1C3:role in prostate disease and the development of specific inhibitors.[J].Molecular&Cellular Endocrinology,2006,248(1):182-191.DOI:10.1016/j.mce.2005.12.009)。在抗去势性前列腺癌(CRPC)中,瘤内雄激素生物合成中涉及AKR1C3,其分别促进弱雄激素雄烯二酮(A'二酮)至更具活性的雄激素睪固酮及5α-雄固烷二酮(5α-二酮)至DHT之转化(Liu C,Lou W,Zhu Y,et al.Intracrine Androgens and AKR1C3Activation Confer Resistance to Enzalutamide in Prostate Cancer[J].CancerResearch,2015,75(7):1413-1422.DOI:10.1158/0008-5472.can-14-3080;Fung,K-M.Increased expression of type 2 3-hydroxysteroid dehydrogenase/type 5 17-hydroxysteroid dehydrogenase(AKR1C3)and its relationship with androgenreceptor in prostate carcinoma[J].Endocrine Related Cancer,2006,13(1):169-180.DOI:10.1677/erc.1.01048)。重要的是,相较于在患有原发性前列腺癌之患者体内,AKR1C3表达在患有CRPC之患者体内展示增加(Stanbrough et.al,Cancer Res 2006,66:2815-2825.DOI:10.1158/0008-5472.CAN-05-4000;Hamid AR,Pfeiffer MJ,Verhaegh GW,Schaafsma E,Brandt A,Sweep FC,Sedelaar JP,Schalken JA.Aldo-keto reductasefamily 1member C3(AKR1C3)is a biomarker and therapeutic target forcastration-resistant prostate cancer.Mol.Med.2012;18:1449–1455.DOI:10.2119/molmed.2012.00296;Pfeiffer MJ,Smit FP,Sedelaar JP et al(2011)Steroidogenicenzymes and stem cell markersare upregulated during androgen deprivation inprostate cancer.Mol Med 17:657–664.DOI:10.2119/molmed.2010.00143)。遗传多态性在AKR1C3之AKR1C3基因写码中亦展示为前列腺癌之非依赖性预测子(Yu et.al,PLoSOne2013,8(1):e54627.DOI:10.1371/journal.pone.0054627)。此外,表明了AKR1C3依赖性雄激素重新合成是对诸如阿比特龙(abiraterone)之CYP17A1抑制剂之潜在抗药机制(Mostaghel et.al,Clin Cancer Res2011,17:5913-5925.DOI:10.1158/1078-0432.CCR-11-0728;Cai et.al,Cancer Res2011,71:6503-6513.DOI:10.1158/0008-5472.CAN-11-0532)。因此,AKR1C3可为患有CRPC的患者提前具有前景的治疗标靶(Adeniji et.al,JSteroid Biochem Mol Biol2013,137:136-149.DOI:10.1021/jm3017656)。在多中心阶段I/II研究中,对患有转移性抗去势性前列腺癌之患者测试AKR1C3抑制剂。然而,新颖雄激素生物合成抑制剂并未展示对临床活性之相关迹象(Loriot et.al,Invest New Drugs2014,32:995-1004.DOI:10.1007/s10637-014-0101-x)。最新资料指示CRPC中之AKR1C3活化为与抗雄激素(恩杂鲁胺enzalutamide)抗药性相关联之重要抗药机制。相较于在亲代细胞中,雄激素前驱体(诸如,胆固醇、DHEA及孕酮)以及雄激素在抗恩杂鲁胺前列腺癌细胞中可展示高度调升。资料表明AKR1C3抑制路径可充当恩杂鲁胺敏化治疗且对患有抗恩杂鲁胺CRPC之患者有恢复功效(Liu C,Lou W,Zhu Y,et al.Intracrine Androgens and AKR1C3Activation Confer Resistance to Enzalutamide in Prostate Cancer[J].CancerResearch,2015,75(7):1413-1422.DOI:10.1158/0008-5472.can-14-3080)。假定使用AKR1C3抑制剂共同治疗将解决恩杂鲁胺抗性且提高晚期前列腺癌患者之存活期(Thomaet.al,Nature Reviews Urology 2015,12:124.DOI:10.1038/nrurol.2015.23)。
AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病特别的包括抗蒽环类霉素癌。蒽环类霉素(或蒽环类抗生素)为用于癌症化学疗法之一类药物,且衍生自链霉菌细菌波塞链霉菌青灰变种(Fujiwara et.al,Streptomyces bacterium Streptomycespeucetius var.Caesius,Critical Reviews in Biotechnology,1985,3(2):133.DOI:10.3109/07388558509150782)。此等化合物用于治疗许多癌症,包括白血病、淋巴瘤、乳癌、胃癌、子宫癌、卵巢癌、膀胱癌及肺癌。蒽环类霉素为曾经所研发之抗癌治疗当中最有效的。然而,用于癌症治疗的蒽环类霉素之临床成果被抗药性弱化。已越来越普遍认可蒽环类霉素至其较弱C13-羟基次级代谢物的较高酶还原构成了引起肿瘤之蒽环类霉素抗性的机制中之一者(Gavelova et.al,2008Chem.Biol.Interact176,9-18.DOI:10.1016/j.cbi.2008.07.011;Heibein et.al,2012BMC Cancer12,381.DOI:10.1186/1471-2407-12-381)。阿霉素之酶代谢是造成在阿霉素化学疗法后观测到的心肌病的原因。已有文献展示诸如阿霉素及道诺霉素(daunorubicin)之临床上投与的蒽环类霉素之代谢中涉及AKR1C3(Novotna et.al,Toxicol.Letter 2008,181:1-6.DOI:10.1016/j.toxlet.2008.06.858)。在2012年,亚洲乳癌患者已展示阿霉素药效学与AKR1C3遗传变异体之相关性:一种遗传变异体与较长无进展存活期及在基于阿霉素之疗法之后的整体存活期相关联,从而表明与阿霉素代谢之潜在交互作用(Voon et.al,British J of ClinPharmacology2012,75:1497-1505.DOI:10.1111/bcp.12021)。最近,可证实AKR1C3促进癌细胞对蒽环类霉素治疗之抗性,且因此具有蒽环类霉素的特定AKR1C3抑制剂之伴随投与可为用于成功预防及治疗抗蒽环类霉素抵肿瘤之有效策略(Hofman et.al,Toxicology andApplied Pharmacology2014,278:238-248.DOI:10.1016/j.taap.2014.04.027)。
研究还表明,AKR1C3在食管癌,前列腺癌和非小细胞肺癌的放射治疗抵抗性中起关键作用(Sun et al Overexpression of AKR1C3 significantly enhances humanprostate cancer cells resistance to radiation.Oncotarget.2016Jul26;7(30):48050-48058.DOI:10.18632/oncotarget.10347;Xiong et al.;Elevated Expression ofAKR1C3 Increases Resistance of Cancer Cells to Ionizing Radiation viaModulation of Oxidative Stress.PLoS ONE 2014 9(11):e111911.DOI:10.1371/journal.pone.0111911)。使用来自前列腺细胞系DU145及其稳定高表达AKR1C3的相应细胞系(AKR1C3-over)研究了前列腺癌细胞中的AKR1C3抗放射性的作用。吲哚美辛是AKR1C3活性的特异性抑制剂,它可明显增强前列腺细胞对放射治疗的敏感性。研究发现PGF2α不仅可以促进前列腺癌细胞的增殖,还可以增强前列腺癌细胞对辐射的抵抗力。PGF2α在AKR1C3-over细胞中的积累导致激活MAPK通路的激活并抑制PPARγ的表达。同时研究发现AKR1C3高表达可引起NSCL抗辐射性(Xie et al;Aldo-keto reductase 1C3 maybe a newradioresistance marker in non-small-cell lung cancer.Cancer Gene Ther.2013Apr;20(4):260-6.DOI:10.1038/cgt.2013.15)。在A549/R和SPCA1/R细胞中,AKR1C3mRNA和蛋白水平显着上调。A549/R和SPCA1/R中的AKR1C3蛋白水平比敏感型的对照细胞要分别高6.2倍和3.5倍。以上研究表明,降低AKR1C3表达可有效增加NSCLC细胞对放射治疗的敏感性。
AKR1C3表达在抗免疫治疗患者中明显上调。已有文献报导13例接受抗PD-1治疗的肾细胞癌患者中,有4名有反应者(R),9名无反应者(NR);全基因组分析显示234个基因在R与NR中表达具有显著差异。其中之一的显著差异基因是在无反应者中AKR1C3表达明显增高(Ascierto 2015The intratumoral balance between metabolic and immunologic geneexpression is associated with anti-PD-1response in patients with renal cellcarcinoma Cancer Immunol Res 2016 4 726-733,doi:10.1158/2326-6066.CIR-16-0072.)
研究表明联合使用AKR1C3特异性抑制剂和daunorubicin或cytarabine等化疗药物可大幅度增加血癌细胞的杀伤能力(Verma et al,Potent and Highly SelectiveAldo-Keto Reductase 1C3(AKR1C3)Inhibitors Act as ChemotherapeuticPotentiators in Acute Myeloid Leukemia and T-Cell Acute LymphoblasticLeukemia.J.Med.Chem.2019,62,7:3590-3616,DOI:10.1021/acs.jmedchem.9b00090)。
AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病特别的包括异位性皮肤炎。抗原对异位性个体的攻击造成PGD2及组织胺之释放,其展示PGD2几乎不促进人类皮肤之实时过敏反应且PGD2为异位性皮肤炎(AD)中促使皮肤发炎的脂质介体(Barret.al,Br J Pharmacol.1988,94:773-80.PMID:2460180;Satoh et.al,J Immunol.2006,177:2621-9.DOI:10.4049/jimmunol.177.4.2621;Shimura et.al,Am J Pathol.2010,176:227-37.DOI:10.2353/ajpath.2010.090111)。PGD2为相对不稳定的促炎性介体,其自发地转化成强抗炎性介体15d-PGJ2。彼转化藉由PGD2藉AKR1C3至促炎性9α,11β-PGF2之代谢来转移(Mantel et.al,Exp Dermatol.2016,25(1):38-43.DOI:10.1111/exd.12854)。经证实,AKR1C3在人类AD样本中调升,且已假定AKR1C3在皮肤病理学(尤其是异位性皮肤炎)及瘢痕瘤中调节发炎之作用(Mantel et.al,J Invest Dermatol 2012,132(4):1103-1110.DOI:10.1038/jid.2011.412;Mantel et.al,Exp Dermatol.2016,25(1):38-43.DOI:10.1111/exd.12854)。AKR1C3抑制可为用于治疗AD及瘢痕瘤之新颖选项。
AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病特别的包括发炎。前列腺素生物合成中涉及AKR1C3,其催化PGH2至PGF2α及PGD2至11β-PGF2之转化。已假定AKR1C3之表现及调升藉由直接引起9α,11β-PGF2合成速率提高以及转移强抗炎性介体15d-PGJ2之自发性产生来支援发炎(Mantel et.al,J Invest Dermatol2012,132(4):1103-1110.DOI:10.1038/jid.2011.412)。亦已在HL-60细胞中(Desmond et.al,Cancer Res2003,63:505-512.PubMed:12543809)及MCF-7细胞中(Byrns et.al,J Steroid BiochemMol Biol 2010,118:177-187.DOI:10.1016/j.jsbmb.2009.12.009)涉及AKR1C3之此功能。假定对AKR1C3之抑制增加15d-PGJ2(抗炎性脂质),其主要经由过氧化体增殖剂活化受体γ(PPAR-γ)之活化及/或对在免疫细胞中传信之NF-κB之抑制直接调节其作用(Maggiet.al,Diabetes 2000,49:346-355.DOI:10.2337/diabetes.49.3.346;Scher et.al,Clinical Immunology 2005,114:100-109.DOI:10.1016/j.clim.2004.09.008)。先前资料已展示PPAR-γ活化减轻小鼠之皮肤及肺脏中之过敏原诱发性发炎(Ward et.al,Carcinogenesis.2006,27(5):1074-80.DOI:10.1093/carcin/bgi329;Dahten et.al,JInvest Dermatol.2008,128(9):2211-8.DOI:10.1038/jid.2008.84)。此表明AKR1C3抑制在抑制发炎方面之作用。
AKR1C3对若干病理性病状/疾病起作用,这些病理性病状/疾病包括其他疾病。此外,AKR1C3抑制剂具有用于治疗以下之潜能:前列腺增生(Roberts et.al,Prostate 2006,66(4),392-404.DOI:10.1002/pros.20362)、脱发(L.Colombe et.al,Exp Dermatol 2007,16(9),762-769.DOI:10.1111/j.1600-0625.2007.00639.x)、肥胖症(P.A.Svenssonet.al,Cell Mol Biol Lett 2008,13(4),599-613.DOI:10.2478/s11658-008-0025-6)、过早性成熟(C.He,Hum Genet 2010,128(5),515-527.DOI:10.1007/s00439-010-0878-4.)及慢性阻塞性肺病(S.Pierrou,Am J Respir Crit Care2007,175(6),577-586.DOI:10.1164/rccm.200607-931OC)。
现已发现本发明之化合物具有抑制AKR1C3活性的效果,因此可用于治疗或预防AKR1C3相关病症,诸如妇科病症(特定言之,子宫内膜异位相关及多囊性卵巢症候群相关妇科病症)、病状及疾病,代谢病症,过度增生性病症、病状及疾病,及发炎病症以及其他相关疾病或病症。

具体实施方式
以下参照具体的实施例来说明本发明。本领域技术人员能够理解,这些实施例仅用于说明本发明,其不以任何方式限制本发明的范围。
下述实施例中的实验方法,如无特殊说明,均为常规方法。下述实施例中所用的药材原料、试剂材料等,如无特殊说明,均为市售购买产品。
“患者”及“个体”可互换使用,是指需要癌症治疗的哺乳动物。通常,患者是人类。通常,患者是诊断患有癌症的人类。在某些实施例中,“患者”或“个体”可指用于筛选、表征及评估药物及疗法的非人类哺乳动物,例如非人类灵长类动物、狗、猫、兔、猪、小鼠或大鼠。
“前药”是指投与或施用之后经新陈代谢或以其他方式转化为关于至少一种性质的生物学活性或活性更高的化合物(或药物)的化合物。相对于药物,前药以使其相对于药物活性较低或无活性的方式化学修饰,但化学修饰使得在前药投与之后通过代谢或其他生物过程产生相应药物。前药可相对于活性药物具有改变的代谢稳定性或输送特征、较少副作用或较低毒性或经改良的风味(参见(例如)参考文献Nogrady,1985,MedicinalChemistry A Biochemical Approach,Oxford University Press,New York,第388页至392页,其以引用式并入本文中)。前药可使用除相应药物以外的反应物来合成。
“实体肿瘤”是指包括(但不限于)骨、脑、肝、肺、淋巴结、胰脏、前列腺、皮肤及软组织(肉瘤)中的转移肿瘤的实体肿瘤。
药物的“治疗有效量”是指当向患有癌症的患者投与或施用时,将具有预期的治疗效应(例如患者中一或多种癌症的临床表现的缓和、改善、缓解或消除)的药物的量。治疗效应不必通过投与或施用一个剂量而出现,且可仅在投与或施用一系列剂量后出现。因此,治疗有效量可以一或多次来投与或施用。
病况或患者的“治疗”是指采取步骤以获得有益或期望结果(包括临床结果)。出于本发明的目的,有益或期望临床结果包括(但不限于)一或多种癌症症状的缓和或改善;疾病程度的减弱;疾病进展的延迟或减缓;疾病状态的改善、缓解或稳定;或其他有益结果。在一些情形下,癌症的治疗可使得部分反应或稳定疾病。
“肿瘤细胞”是指任何适当物种(例如,哺乳动物,例如鼠类、犬、猫、马或人类)的肿瘤细胞。
放射疗法,即癌症的放射疗法,放射治疗有多种实施方法,最常用的是:
光子(γ-射线)束放射,由直线加速器发射大量光子(γ-射线)束;
中子束放射,可用于治疗组织边缘狭窄的某些癌肿;
电子束放射,因具有穿透组织极浅的特性,适用于治疗皮肤或表浅癌肿;
质子放射,虽用途有限,但对需要深度而范围极狭小的照射野可提供锐利的射线周缘;
近距放射,将强力放射源,通过针头植入肿瘤组织本身(如前列腺或肺部),从而达到小范围高剂量的效应;
全身性放射性核素治疗,可用于有核素摄吸的器官受体(如甲状腺癌)或抑制全身骨骼部位的受体(如治疗转移性前列腺癌的放射性锶)。
痊愈性放射治疗一般需将肿瘤局部或其局部区域包含在照射野之内。
放射性照射细胞损伤是无选择性的和非特异性的,对DNA产生复杂的作用,疗效优劣按细胞损伤程度超越其修复能力的多少而定。一般来说,正常组织的修复效率高于癌细胞,从而是的放射疗法能使得病人获益。
化疗,化疗是化学药物治疗的简称,通过使用化学治疗药物杀灭癌细胞达到治疗目的。化疗是目前治疗癌症最有效的手段之一,和手术、放疗一起并称癌症的三大治疗手段。手术和放疗属于局部治疗,只对治疗部位的肿瘤有效,对于潜在的转移病灶(癌细胞实际已经发生转移,但因为目前技术手段的限制在临床上还不能发现和检测到)和已经发生临床转移的癌症就难以发挥有效治疗了。而化疗是一种全身治疗的手段,无论采用什么途径给药(口服、静脉和体腔给药等),化疗药物都会随着血液循环遍布全身的绝大部分器官和组织。因此,对一些有全身播撒倾向的肿瘤及已经转移的中晚期肿瘤,化疗都是主要的治疗手段。一般而言化疗的药物都是细胞毒性药物,其能直接杀死细胞,但由于癌细胞、正常细胞的某些特性不同,常常使得化疗药物对癌细胞的杀灭作用更大,从而能使得病人获益。但化疗依然存在严重的毒副作用,包括消化系统反应、骨髓抑制、脱发等,某些毒副作用会然部分患者无法再继续接受化疗或某种化疗药物。
免疫疗法。正常情况下,人体的免疫系统可以识别并清除肿瘤微环境中的肿瘤细胞,但为了生存和生长,肿瘤细胞能够采用不同策略,使人体的免疫系统受到抑制,不能正常的杀伤肿瘤细胞,从而在抗肿瘤免疫应答的各阶段得以幸存。人体免疫系统识别并清除肿瘤细胞的过程(肿瘤-免疫循环)具有多个环节,任一环节被抑制,都能导致肿瘤细胞不能被正常的清除。不同肿瘤可以通过不同环节的异常抑制免疫系统对肿瘤细胞的有效识别和杀伤从而产生免疫耐受,甚至促进肿瘤的发生、发展。
肿瘤免疫治疗就是通过重新启动并维持肿瘤-免疫循环,恢复机体正常的抗肿瘤免疫反应,从而控制与清除肿瘤的一种治疗方法。包括单克隆抗体类免疫检查点抑制剂、治疗性抗体、癌症疫苗、细胞治疗和小分子抑制剂等。近几年,肿瘤免疫治疗的好消息不断,目前已在多种肿瘤如黑色素瘤,非小细胞肺癌、肾癌和前列腺癌等实体瘤的治疗中展示出了强大的抗肿瘤活性,多个肿瘤免疫治疗药物已经获批准临床应用。
