Description

作用于Dectin-1的稠合吖啶衍生物及其用途
技术领域
本发明涉及药物化学领域,更具体地说,涉及作为Dectin-1小分子配体的稠合吖啶衍生物的合成及抗炎活性。
背景技术
炎症是指机体对感染、外来物质或其它原因(如抗原抗体复合物)所致损伤的一种反应。适当的炎症反应有利于损伤的减轻和修复,但炎症反应过度时就会引起急性或慢性炎症性疾病,如风湿病、肺炎、支气管炎、心内膜炎、肠炎、肾炎、胃炎、盆腔炎、关节炎等。炎症细胞因子在调控炎症反应中发挥着重要的作用,包括促炎因子(如IL-1β、IL-6和TNF-α)和抑炎因子(如IL-10和IL-13)。
Dectin-1(树突状细胞相关性C型植物血凝素-1)是Ariizumi等在2000年克隆到的一种β-葡聚糖受体,能特异性识别真菌细胞壁的β-1,3和β-1,6糖苷键的葡聚糖。Dectin-1主要表达在免疫相关的器官,如脾、胸腺、淋巴结等;具体到细胞,则广泛分布于单核/巨噬细胞、树突状细胞、自然杀伤细胞、中性粒细胞等,是能诱导细胞内信号的模式识别受体。[Ariizumi K.;Shen G.L.;Shikano,S.;Xu S.;Ritter R.et al.J.Biol.Chem.2000,275(26):20157-20167];[Brown G.D.Gordon S.Nature.2001,413:36-37.];[Taylor P.R.;BrownG.D.et al.J.Immunol.2002,169(7):3876-3882];[Heinsbroek S.E.M.;TaylorP.R.et al.J.Immunol.2006,176(9):5513-5518]。
与配体结合后,Dectin-1位于胞质中的ITAM区域,在Src家族激酶作用下,发生酪氨酸激酶磷酸化从而介导信号转导。Dectin-1能够独立通过CARD9募集Bcl10和Malt-1,活化后的CARD9与Bcl10、Malt-1形成复合体,激活IκB激酶(κB kinase,IKK),使IκB发生磷酸化,促进其降解,从而激活经典的NF-κB通路[Gross,O.et al.Nature.2006,442(7103):651-656.]。此外Dectin-1也可以通过Raf-1-NIK(NF-κB-inducing kinase)激活非经典的NF-κB通路[Gringhuis S.I.;den Dunnen J.;Litjens M.et al.Nat.Immunol.2009,10,203-213.]。Raf-1被激活后选择性的磷酸化NF-κB的P65亚基,促进其乙酰化,乙酰化的P65可以与P50结合增强其转录活性,或者与Rel-B结合抑制其转录活性。NF-κB激活后可以启动多种细胞因子的转录表达,如IL-2、IL-10、IL-6、TNF-α、IL-23,这些细胞因子可以诱导T细胞的分化,调节细胞免疫,并对机体的适应性免疫产生影响。[Leibund Gut-Landmann S.etal.Nat Immunol.2007,8(6):630-638];[Leibundgut-Landmann,S.et al.Blood.2008,112(13):4971-4980]
近年来研究发现,Dectin-1在诱导适应性免疫中发挥着重要作用。研究显示,在经高纯的β-葡聚糖刺激后的树突细胞中,Dectin-1途径能诱导体内体外Th17和Th1CD4+细胞的分化,并且这些反应不依赖于TLR信号途径。在人体中,体内真菌感染也能观察到相似的反应。用特异Dectin-1激动剂激活树突细胞能促使调节性T细胞向产生IL-17的T细胞群转变,尽管Dectin-1促进Th17反应的具体机制还不清楚,但其在真菌感染中的促炎症反应和抗炎症反应之间确实起着关键作用。[Acosta-Rodriguez EV;Rivino L;Geginat J.etal.Nat Immunol.2007,8(6):639-646][Osorio F.et al.Eur J Immunol.2008,38(12):3274-3281]
Dectin-1介导的反应可能也与促进自身免疫有关。有研究显示,Dectin-1的配体能诱导SKG小鼠的自身免疫关节炎,而Dectin-1抗体介导的抑制作用能抑制该疾病的发展。同样地,Dectin-1阻断剂能抑制实验性自身免疫性葡萄膜视网膜炎,该疾病是一个因视网膜抗原失效诱导的Th1/Th17疾病,并且Dectin-1可能还与其他类似的自身免疫疾病有关。这些疾病的发生部分程度上可能是由于Dectin-1能够提供内源性抗原有关。[YoshitomiH;Sakaguchi N;Kobayashi K.et al.J Exp Med.2005,201(6):949-960];[Weck MM;AppelS;Werth D.et al.Blood.2008,111(8):4264-4272]
β-葡聚糖是真菌细胞壁的主要组成分子,而Dectin-1作为这些碳水化合物分子的主要受体,表达在免疫细胞以及病原侵袭时的关键部位,在抗真菌免疫中具有重要作用。Dectin-1被证实能介导几种重要的病原真菌的识别,包括念珠菌、曲霉、肺囊虫和球孢子菌属[Tsoni SV;Brown GD.Ann N Y Acad Sci.2008,1143:45-60]。目前Dectin-1在胞内的具体作用仍存在争议,但是有确凿的证据显示这个受体能控制白念珠菌、卡氏肺囊虫和烟曲霉的感染[Gross,O.et al.Nature.2006,442(7103):651-656];[Steele C.et al.J ExpMed.2003,198(11):1677-1688];[Viriyakosol S.et al.MBio.2013,4(1):e00597-12]。这些研究显示鼠中Dectin-1在真菌的摄取、杀伤和早期炎症反应的诱导中是必需的,研究结果显示与这个受体胞外的功能相关联。由于Dectin-1的这个作用,病原真菌具有掩饰它们的β-葡聚糖以避免免疫识别的能力,这些发现提示人们开发能提高这些碳水化合物的暴露的药物。
除此之外,Dectin-1能识别结核分歧杆菌,但分歧杆菌表面并不表达β-葡聚糖,表明Dectin-1可能还有其他的识别配体。[Rothfuchs A.G.;Bafica A.;Feng C.G.et al.JImmunol.2007,179(6):3463-3471]
总之,Dectin-1是诱导自身胞内信号的模式识别受体,可以促进树突细胞的成熟和吞噬作用,介导多种细胞因子、趋化因子的分泌,如TNF-α、IL-6、IL-1β、IL-1α、CXCL2、CCL3等。此外,Dectin-1还能与其他模式识别受体(如Toll样受体)协同作用。因此,Dectin-1在调节机体免疫、炎症方面具有重要的意义。但是,作为一个β-葡聚糖受体,目前尚未有Dectin-1小分子配体的报道。

表面等离子共振(SPR)实验
实验中以PBS+5%DMSO缓冲液为参比,Dectin-1蛋白为对象,对本发明的化合物,首先进行了初筛实验,测试初始浓度为25μM时与Dectin-1的结合活性。
初筛结果表明,所有的化合物与Dectin-1的结合能力都比参比样本强,而且有许多化合物解离能力也很弱。一般情况下,与蛋白结合能力强又不易解离的化合物是具有前景的分子,基于这样的原则,本发明人挑选了这种类型的化合物,进行了多循环实验,得到了这些化合物与Dectin-1的亲和力常数KD值。代表性化合物结果如下:
化合物 c-13 a-7 7d 7b 1c a-4 a-6 c-2 c-3 e-2 e-4 e-14
K<sub>D</sub> +++ +++ +++ +++ ++++ + +++ + ++ ++ ++ +++
注:+代表1.0~9.9×10-4M,++代表1.0~9.9×10-5M,+++代表1.0~9.9×10-6M,++++代表1.0~9.9×10-7M。
根据小分子化合物与蛋白的亲和力常数在10-3~10-6M的规律,可以得出这样的结论:本申请的化合物与Dectin-1有很强的亲和力。
抑制炎性因子分泌实验
在免疫反应发生过程中,高表达Dectin-1的巨噬细胞扮演着重要的角色,许多细胞因子即来源于活化的巨噬细胞,其中,TNF-α、IL-6、IL-1β为评价炎症反应发生较敏感的指标。
本实验为在体外模拟炎症发生过程,采用脂多糖(LPS)诱导小鼠腹腔巨噬细胞(RAW264.7)模型,ELISA试剂法检测化合物对细胞分泌的TNF-α、IL-6的抑制作用,评价Dectin-1小分子配体的抗炎活性。初步实验结果如下:

Figure BDA0001661293860000451
初筛结果显示26个化合物中有8个化合物对RAW264.7细胞分泌TNF-α的抑制率优于阳性对照药或抑制率相当,继续对这8个化合物设置复孔进行复筛。结果如下:
Figure BDA0001661293860000452
复筛结果显示,在初筛的基础上,化合物仍然表现出了对TNF-α的分泌有很好的抑制活性,并且其中2个化合物对IL-6分泌有较好的抑制活性。
用100ng/mL酵母多糖Zymosan A代替LPS诱导炎症因子的释放,重复上述实验操作,发现这些化合物在10μg/mL浓度下均能显著抑制TNF-α的产生.
通过ELISA来分析化合物抑制人单核/巨噬细胞THP-1释放IL-1β,实验方法如下:
THP-1细胞在RPM1 1640的培养基,加入10%FBS,在5%(v/v)CO2,37℃下孵育。
THP-1细胞在500nM PMA培养三个小时,之后把5×106个细胞种植到96孔板中,接着用100ng/ml的LPS引发3小时,接着用需要测试的化合物以10μg/mL的剂量分别处理,再用5mM ATP处理1小时,之后用ELISA(Dakewe Biotech Co.Ltd.)来分析上清液中释放的IL-1β的量。实验平行进行三次,取平均值。
实验结果:本发明的化合物a-7,c-3,e-7等在10μg/mL浓度下抑制IL-1β的释放。

30只小鼠随机分为三组,依次为空白组(溶媒组)、对照组(20μg/kg Zymosan A)、给药组(20μg/kg Zymosan A,腹腔注射药物5~20mg/kg),4小时后用ELISA试剂盒检测小鼠腹腔灌洗液中TNF-α的浓度。
实验结果:对照组TNF-α的浓度显著高于溶媒组,给药组(a-7,a-11,c-3,c-7,e-14,3a,7b,7d等)中TNF-α的浓度均显著低于对照组,略高于溶媒对照组,说明本发明的化合物能抑制Zymosan A诱发的小鼠腹膜炎。
工业实用性
本发明提供的稠合吖啶衍生物能够通过作用于Dectin-1,在细胞和动物实验中均能抑制炎性因子的分泌,适于用作抗炎药物。
