Description
技术领域
本发明涉及一种新的环烯衍生物,对产生诱导型一氧化氮合成酶衍生的一氧化氮(NO)具有抑制作用和/或对产生TNF-α、IL-1、IL-6等炎症细胞因子具有抑制作用,可用作治疗和预防心脏病,自身免疫疾病、炎症疾病、中枢神经系统疾病、感染性疾病、脓毒症、脓毒性休克(septic shock)等疾病的药物,并涉及该环烯衍生物的制备方法及其用途。
背景技术
一氧化氮(NO)已被报道在哺乳动物体内的生理活性中起着各种作用,例如,在血管系中作为血管扩张因子[Pharmacol.Rev.第43卷,109-142页(1991)],在白血球系中作为显示杀肿瘤细胞、杀菌作用的因子[Curr.Opin.Immunol.第3卷,65-70页(1991)],以及在神经系中作为神经递质[Neuron,第8卷,3-11页(1992)]。NO基本上是通过NO合成酶(NOS)从L-精氨酸生成。现在,已知存在基因的神经型NOS,血管内皮型NOS,诱导型NOS(iNOS)的3种异构型[Cell,第70卷,705-707页(1992)],从其存在方式上,与后者的iNOS相比,前两者也称为结构型(constitutive)NOS(cNOS)。
cNOS被认为存在于血管内皮细胞内,神经细胞内,是钙-钙结合调节蛋白依赖性的,通过各种受体的刺激被活化,产生少量的NO,并起着上述生理调节作用。而另一方面,已知iNOS通过各种细胞因子或细菌性脂多糖(LPS)等,在巨噬细胞、中性粒细胞等中被诱导,持续产生大量的NO,不仅显示上述生理活性,而且在产生部位对细胞和组织有破坏和伤害作用[Immunol.Today第13卷,157-160页(1992)]。作为表达iNOS的细胞和组织,除了前述细胞外,已知还有肝细胞,枯否氏细胞,神经胶质细胞,血管平滑肌细胞,血管内皮细胞,心肌内膜,心肌细胞,肾小球膜细胞,软骨细胞,滑膜细胞,胰腺β细胞,破骨细胞等[FASEB J.第6卷,3051-3064页(1992)、Arch Surg.第128卷,396-401页(1993)、J.Biol.Chem.第44卷,27580-27588页(1994)、(J.Cell.Biochem.)第57卷,399-408页(1995)]。
到目前为止,作为抑制iNOS的化合物已经报道了L-精氨酸类似物[Pharmacol.Rev.第43卷,109-142页(1991)],氨基胍[Br.J.Pharmacol.第110卷,963-968页(1993)],S-乙基异硫脲[J.Biol.Chem.第43卷,26669-26676页(1994)]等。
另一方面,也已知TNF-α,IL-1,IL-6等细胞因子是由单核细胞,巨噬细胞,淋巴细胞,中性粒细胞,成纤维细胞,血管内皮细胞等各种细胞分泌的,并广泛参与以炎症为基础的生物体防御和免疫系统[The CytokineHandbook,2nd ed Academic Press Limited(1994)、Advances Immunol.第62卷,257-304页(1996)]。
现已阐明TNF-α和IL-1显示各种活性,如(1)发热,(2)巨噬细胞或中性粒细胞等炎症细胞的活化或促进趋药性,(3)诱导IL-1、IL-6、IL-8、TNF、CFS等炎症细胞因子或急性期蛋白,(4)促进NO、O2 -、PAF、前列腺素、白三烯、蛋白酶等各种化学递质的产生;并且IL-6显示(1)诱导急性期蛋白,(2)增加血小板,(3)分化并活化淋巴细胞和NK细胞,(4)增殖破骨细胞等活性。但是,这些细胞因子过剩产生或在不合适的位置和时间产生,对于生物体都会带来不便。例如,在原虫、细菌、真菌、病毒、癌等引起的恶病质,过敏性疾病,慢性类风湿性关节炎,脓肿,移植排斥反应,贫血,动脉硬化,自身免疫疾病,糖尿病,中枢神经系统疾病,炎性肠疾病,心脏病,肝炎,肝硬化,肾炎,骨质疏松症,牛皮癣,脓毒性休克等各种疾病中,已发现有这些细胞因子的参与。有报道说抑制或拮抗一种产生TNF-α、IL-1、IL-6等的物质可成为这些疾病的治疗药[Eur.J.Immunol.第18卷,951-956(1991)、Immunol.第83卷,262-267页(1994)、Proc.Natl.Acad.Sci.第93卷,3967-3971页(1997)、J.Immunol.第147卷,1530-1536页(1991),Immunol.Today.第12卷,404-410页(1991)]。
到目前为止,为治疗心脏病,自身免疫疾病,炎症疾病,脓毒性休克等的抑制由iNOS诱导细胞产生NO的物质,作为预防和治疗各种疾病的药物被认为是有效的,例如,动脉硬化,心肌炎,心肌病,脑缺血性障碍,阿耳茨海默氏病,多发性硬化症,脓毒性休克,慢性类风湿性关节炎,变形性关节炎,胃溃疡,十二指肠溃疡,溃疡性大肠炎,糖尿病,肾小球性肾炎,骨质疏松,肺炎,肝炎,牛皮癣,移植排斥反应或疼痛等。另外,由于作为细胞因子目标的细胞是多样的,有炎症系,血管系,中枢神经系,造血系,内分泌系等,因此,其生物活性也被认为是多样的,但是,这些化合物,在活性方面不完全令人满意,并且存在不仅抑制iNOS,还抑制承担生理活性的cNOS的问题。因此,基于这一点,本发明是要提供进一步改良的预防或治心脏病、自身免疫疾病、炎症疾病、脓毒性休克等疾病的药物。
发明的公开
鉴于以上现状,本发明人探索和研究了一种用于预防或治疗前述疾病的药物,该药物抑制从iNOS诱导细胞产生NO和/或抑制炎症细胞因子的产生,并首次合成了具有下式(1)的化合物或其盐:其中
R1表示可具有取代基的脂肪族烃基,可具有取代基的芳香烃基,可具有取代基的杂环基,式OR1a的基团式中R1a表示氢原子或可具有取代基的脂肪族烃基,或式(a)的基团:式中,R1b和R1c可相同或不同,各自表示氢原子,或可具有取代基的脂肪族烃基;

m表示0-2的整数;

条件是,X是亚甲基时,Y表示可具有取代基的亚甲基。
并发现,所得化合物基于其化学结构而对NO和/或细胞因子的产生等具有预想不到的优异的抑制活性;其优异的抑制作用不仅抑制从iNOS诱导细胞产生NO,而且抑制炎症细胞因子的产生,能作为一种比常规的药物更有效的预防和治疗剂。还发现,该化合物对于被认为不是TNF-α、IL-1、IL-6等炎症细胞因子或NO各自单独参与的而是通过它们复杂的相互关系而恶化的心脏病、自身免疫疾病、炎症疾病、脓毒性休克等疾病,作为临床用的药物具有优异的性能。
