Abstract

一类具有消炎免疫活性的磺酰基取代呋喃类化合物及其衍生物,其以如下(I)所示: />所述化合物及其衍生物具有消炎免疫活性。

Description

一类具有消炎免疫活性的磺酰基取代呋喃类化合物及其衍生物 技术领域
本发明涉及一类磺酰基取代呋喃类化合物、或其立体异构体、或其药物上可接受的盐或其溶剂化物。本发明进一步涉及含有至少上述化合物的药物组合物,其用于治疗自身免疫性疾病。
背景技术
自身免疫性疾病是机体对自身抗原发生免疫反应而导致自身组织损害所引起的一类疾病。目前国内外对IL-12家族的研究主要围绕自身免疫性疾病,如多发性硬化(multiple sclerosis,MS)、炎症性肠病(inflammatory bowel disease,IBD)、类风湿性关节炎(Rheumatoid Arthritis,RA)、银屑病(psoriasis)等。
类风湿性关节炎是以关节滑膜慢性炎症为主的自身免疫性疾病,可引起关节肿痛,继而导致软骨破坏,引起关节畸形,最终出现不同程度的残疾。如不给予适当治疗,通常会导致关节破坏和畸形,并且影响到患者的生活质量。
银屑病俗称“牛皮癣”,是一种常见的易于复发的慢性炎症性皮肤病,特征性损害为红色丘疹或斑块上覆有多层银白色鳞屑.青壮年发病最多,男性发病多于女性。病因和发病机理未完全明确,研究发现,本病的发病与遗传因素、感染链球菌、免疫功能异常、代谢障碍及内分泌变化等有关。银屑病是复发性、难治性疾病,对患者造成极大的身体上和精神上的伤害。
本发明涉及一类新的磺酰基取代呋喃类化合物,其可有效的抑制各类炎症。
发明内容
本发明提供了一种具有抑制自身免疫性疾病活性的磺酰基取代呋喃类化合物及其衍生物。
本发明目的是所述化合物用于治疗各种自身免疫性疾病,或其立体异构体、互变异构体、药物上可接受的盐、溶剂化物或其前药。

其中,T为时间,W为体质量,WLS为肝脾合重。
血清溶血素水平实验:在灭菌操作下,自鸡翼下静脉采血,置100ml疫苗瓶中,加入相当于鸡血容积5倍的Alsever`s溶液混匀,4℃冰箱贮存。临用时,用氯化钠注射液洗涤3次,前2次离心力为250g,离心5min,弃上清液和界面的白细胞层,最后再连续2次离心450g,离心5min,直至红细胞比容恒定,按此值,用氯化钠注射液配成50ml/L浓度的鸡红细胞混悬液。取3只豚鼠血清混合,测定A值时配成比容浓度使用。取昆明种小鼠,随机分组,分别按照25、50、100mg/kg施予本申请化合物,并设置正常对照组、模型组,每组10只。正常对照组和模型组每天20ml/kg灌胃生理氯化钠溶液,其余各组每天灌胃与生理氯化钠溶液等容量不同浓度药物,本申请化合物按照低、中和高剂量组按20ml/kg灌胃给药,连续7d。于给药第8天,除正常对照组外,各组按0.2ml/只腹腔注射50mg/L鸡红细胞进行免疫,免疫后继续给药7d,末次注射1h后,于眼球后静脉丛取血,分离血清,取血清50μl稀释至5ml,取稀释血清2ml与50mg/L鸡红细胞混悬液0.5ml、100ml/L补体0.5ml混合,在37℃水浴中保温30min后,0℃冰浴中30min,中止反应。离心,取上清液于分光光度计540nm处测A值。另设不加血清的空白管,即50mg/L鸡红细胞混悬液1ml,100ml/L补体1ml混合,在37℃水浴保温30min后,0℃冰浴中30min,中止反应。离心,取其上清液作为比色时调“0”的基准。以A值为指标,比较各组间的差异。

机体的免疫由特异性免疫和非特异性免疫所组成。单核巨噬细胞是机体最重要的防御系统,主要介导非特异性免疫,单核巨噬细胞的吞噬能力是平衡机体非特异性免疫功能的标志之一。墨汁中的颗粒状异物进人小鼠血液循环后,可迅速被单核细胞清除,主要为肝脏和脾脏中的巨噬细胞所吞噬。当异物量恒定时,其血流中异物的清除率可以反映单核细胞的吞噬功能。吞噬指数代表的就是碳粒的清除速率。因为肝脏与脾脏的重量不同,所以需要对吞噬指数进行校正,校正后的指数称之为吞噬系数,反映的是每单位组织重量的吞噬活性。结果发现本申请化合物可以明显提高小鼠的吞噬系数,说明本申请化合物可以增强正常小鼠非特异性免疫功能.

溶血素实际上是初次免疫反应的抗体。溶血素能间接反应抗体生成的多少,而抗体是血清杀灭病原体的重要活性物质,是体液免疫的标志。正常细胞受鸡红细胞免疫后,即可产生抗鸡红细胞抗体(溶血素),这种抗体在体外与鸡红细胞补体一起温育,即可使鸡红细胞溶解,释出血红蛋白,使溶液呈红色,颜色的深浅,反映了红细胞溶出量的多少,而红细胞溶血与血清中的抗体含量有关。因此,测定其上清液的A值,可间接判断血清中抗体形成的数量,A值越大,说明产生抗体量越多。
