Abstract
本发明提供一种结构新颖、活性好、选择性高的三环类血浆激肽释放酶抑制剂化合物,可广泛用于涉及血浆激肽释放酶活性相关的疾病的预防或治疗。
Description
技术领域
本发明涉及对血浆激肽释放酶具有选择性抑制活性的三环类化合物及其用途。
背景技术
血浆激肽释放酶(plasma kallikrein,PK)属丝氨酸蛋白酶家族的一员,最早是在哺乳动物的血浆中被发现。它由位于4q35染色体上单个基因(KLKB1)编码,主要在肝脏中合成并以血浆激肽释放酶原(PPK)形式大量存在于血液循环中,PPK进一步通过凝血因子XIIa剪切其内在的Arg-IIe键激活转化成PK(Yousef,G.M.et al.An overview of thekallikrein gene families in humans and other species:Emerging candidatetumour markers.Clin.Biochem.2003,36,443-452)。PK是激肽释放酶-激肽系统(KKS)的一个关键酶,可作用于高分子量激肽原(KH),从而使其活化释放小分子缓激肽(BK),进而通过作用于缓激肽受体参与凝血、纤维蛋白溶解、补体激活以及炎症发生等生物学过程。
近年来,随着对血浆激肽释放酶的基因学、分子学和药理学的研究更加深入,人们对其生理和病理角色有了深入的认识。研究表明,血浆激肽释放酶与炎症性疾病、肿瘤、心血管疾病、肾病、中枢神经系统疾病、视网膜病以及糖尿病视网膜疾病等多种疾病密切相关(Costa-Neto,C.M.et al.Participation of kallikrein-kinin system in differentpathologies.Int.Immunopharmacol.2008,8,135-142)。例如遗传性血管水肿(HAE),它是一种常染色体显性遗传性,主要是由于患者体内C1-INH缺乏,导致其对血浆激肽释放酶的抑制作用减弱,不受控制的激活KKS系统,释放血管活性物质,使血管通透性增加引起典型的肿胀(Farkas,H.Orphan drugs for the treatment of hereditaryangioedema.Expert Opinion on Orphan Drugs,2015,1,141-156)。目前已有艾卡拉肽和Lanadelumab等大分子血浆激肽释放酶抑制剂上市在临床上用于治疗遗传性血管水肿,疗效显著。又例如,在糖尿病黄斑水肿患者眼部玻璃体中,发现其KKS系统过度激活,导致视网膜血管通透性增加和视网膜增厚。近年来已公开多项资料表明血浆激肽释放酶抑制剂可以降低视网膜血管通透性,用于治疗糖尿病视网膜疾病和糖尿病黄斑水肿(Feener,E.P.Plasma kallikrein and diabetic macular edema.Curr.Diab.Rep.2010,10,270-275;Liu J.et al.Plasma kallikrein-kinin system and diabeticretinopathy.Biol.Chem.2013,394,319-328)。目前已有小分子(NCT03466099)和多肽类(NCT03511898)血浆激肽释放酶抑制剂用于治疗糖尿病黄斑水肿进入临床研究。
然而,现有报道的多肽和小分子类血浆激肽释放酶抑制剂又存在诸多限制。如艾卡拉肽被报道存在引起过敏性反应的风险(Banta,E.et al.Overview of ecallantide inthe treatment of hereditary angioedema types I and II.Therapy.2010,7,565-571)。而现有报道的绝大部分小分子血浆激肽释放酶抑制剂具有高度极性和可离子化的胍基或脒基官能团,这被认为难以透过生物膜导致口服生物利用度非常差(Tamie,J.etal.ASP-634:an oral drug candidate for diabetic macular edema.ARVO AnnualMeeting Abstract,2012,53,2240)。Biocryst开发了口服血浆激肽酶抑制剂BCX4161(Collis,P.et al.,BCX4161,an oral kallikrein inhibitor:safety andpharmacokinetic results of a Phase 1study in healthy volunteers.J.AllergyClin.Immunol 2014,133,Volume 133,Issue 2,Supplement,2014,AB39),但是其临床给药剂量为400mg每次,每日三次给药。结构中苯甲脒或胍基虽构成BCX4161的药效基团,但其较差的理化性质可能影响了药物的生物利用度,因此需以较大剂量给药。此外现有的血浆激肽释放酶抑制剂还存在对相关酶如KLK1、凝血酶和其他丝氨酸蛋白酶选择性较差的问题。至今还没有小分子的血浆激肽释放酶抑制剂被批准上市。因此,研究新型、作用力更强、副作用更小的选择性血浆激肽释放酶抑制剂仍有需求。

称取实施例化合物适量,加入DMSO溶解为10mM的母液;取适量体积母液,100%乙腈稀释到100μM。
2.2实验步骤
准备2块96孔孵育板,分别命名为T60孵育板和NCF60孵育板。在T60孵育板和NCF60孵育板上分别加入445μL微粒体工作液(肝微粒体蛋白浓度为0.56mg/mL),然后将上述孵育板放置于37℃水浴锅中预孵育大约10分钟。
预孵育结束后,在T60孵育板和NCF60孵育板上分别加入5μL供试品或对照化合物溶液,混匀。在NCF60孵育板上每孔添加50μL磷酸钾盐缓冲液启动反应;在T0终止板中加入180μL的终止液(含200ng/mL tolbutamide和200ng/mL labetalol的乙腈溶液)和6uL的NADPH再生体系工作液,从T60孵育板中取出54μL样品至T0终止板(T0样品产生)。在T60孵育板上每孔添加44μLNADPH再生体系工作液启动反应。在Blank板中只添加54μL微粒体样品溶液、6uL的NADPH再生体系工作液和180μL的终止液。因此,在供试品或对照化合物的样品中,化合物、睾酮、双氯芬酸和普罗帕酮的反应终浓度为1μM,肝微粒体的浓度为0.5mg/mL,DMSO和乙腈在反应体系中的终浓度分别为0.01%(v/v)和0.99%(v/v)。孵育适当时间(如5、10、20、30和60分钟)后,分别在每个终止板的样品孔中加入180μL的终止液(含200ng/mLtolbutamide和200ng/mL labetalol的乙腈溶液),之后从T60孵育板中取出60μL样品以终止反应。所有样品板摇匀并在3220×g离心20分钟,然后每孔取80μL上清液稀释到240μL纯水中用于液相色谱串联质谱分析。
3.液相色谱串联质谱对所有样品进样分析,以体外代谢半衰期(T1/2,min)和固有清除率(CLint)作为指标,考察化合物的代谢稳定性,结果如表5所示:
