Description
本发明涉及分子式(1)-(16)的新型肽:
D-Arg-Lys-D-Asp,(1)
Arg-D-Lys-Asp,(2)
D-Arg-D-Lys-D-Asp,(3)
Arg-D-Lys-D-Asp,(4)

Arg-Lys-D-Asp(Val) (16)
它们的酸加成盐和含有这些肽的药物组合物。
另一方面,本发明提供了分子式(1)-(16)的新型肽和含有它们的药物组合物的制备方法。
上述分子式(1)-(16)的肽能够抑制免疫系统的某些部分的作用。
本发明还涉及通过采用上述肽或含有它们的组合物来抑制免疫系统的功能而治疗包括人在内的哺乳动物的一种方法。
本发明的化合物是胸腺生成素的活性中心的衍生物和非对映体。但是,当已知的肽Arg-Lys-Asp,Arg-Lys-Asp-Val(匈牙利专利说明书第185,263号)和Arg-Lys-Asp-Val-Tyr(匈牙利专利说明书第183,579号)被考虑作为胞腺生成素的活性中心时,会产生明显的刺激免疫效应[Drugs of the Future 11,764(1986),和Drugs of Today 22,17(1986)],本发明的肽甚至会显示出相反的活性。
业已知道,几种疾病的起因或伴随综合症可归咎于免疫系统的动态功能的失调。免疫刺激剂被用于治疗遗传的,天生的(出生后或分娩后,老年)和后天的免疫缺乏疾病(例如,感染后和手术后,爱滋病等)。但是,所存在的几种疾病或症状可归因于因机体的防御机理的自发修饰而导致免疫系统功能增加或出现暂时的不需要的功能。在自身免疫疾病中,防御系统不可能从“外源”中区别出“自身”,因此,它通过所产生的抗体而保护了不受自身抗原的作用。此外,借此出现了严重的后果。过敏性疾病是由于外源物质引起抗体的产量增加而引起的。随器官移植的排异反应也是机体正常和健康的功能,但是,它应在短时内停止以允许移植的外源器官在机体内组建。
环磷酰胺{2-[双(2-氯乙基)氨基]-四氢-2H-1,3,2-氧氮磷杂环己烷氧化物},硫唑嘌呤[6-(1-甲基-4-硝基-5-咪唑硫基)嘌呤]和皮质甾类被用于治疗自身免疫疾病,和H-1阻断受体的抗阻胺药被用于治疗过敏症,环孢菌素(cyclosporin)是一种用于器官移植的必需药,它属于免疫抑制剂,可抑制免疫功能的增加或抑制免疫系统的正常功能的减弱。
一些伴随的副作用可以通过免疫抑制药物的相对低的治疗指数(<10)来解释。因此,它们只能在严格的医疗控制条件下用药,同时,通常只能用一个有限的时期。肽型活化剂的一个特别的优点在于它们具有超高的治疗指数(>100-1000),即通常,它们的引发有害效应的剂量比它们的有效剂量高几个数量级,在生理条件下,它们迅速地降解,不在机体内积聚。在短的使用寿命内,它们的效应取决于它们高效地启动复杂活动的能力。
业已发现,新型的,分子式(1)-(16)的Arg-Lys-Asp和Arg-Lys-Asp-Val免疫刺激肽为含有D-氨基酸的非对映体和在赖氨酸的α-或α-和ε-氨基上连接有精氨酸以及在天门冬氨酸的β-羧基上含有缬氨酸的称谓的异构肽所在几个免疫试验中显示了抑制效应。尽管根据迄今为止我们所得到的知识(如可参考美国专利说明书第4,505,853号),两种类型的修饰通常是多少有些伴随着耐酶性的增加,肽稳定性的增强和初始生物效应的较长时间的持续。
本发明的分子式(1)-(16)的新型肽是通过在溶液中连续采用活性酯的偶合步骤而逐步使链加长的方法和/或肽化学中已知的混合酸酐方法而制备的,α-氨基和/或α-和ε-氨基的结合步骤是:
(a)从以含有可通过氢化作用或酸解而除去的基团所酯化的羧基的羧基末端氨基酸衍生物,和随机地,以一种保护氨基的侧链和/或一种通过氢化或酸解可除去的基团所酯化的羧基和一种游离氨基开始,制得分子式(1)-(16)的肽的衍生物,它们的羧基上进行了酯化,在不包含于肽链中的氨基侧链上具有保护基团Boc和/或Z,
(b)然后,通过催化氢化和/或酸处理除去存在的保护基团,和,
(c)如果需要的话,通过用酸处理而将分子式(1)-(16)的游离肽转化为它们的酸加成盐。
在合成中可以使用组合的保护基,这样,有可能选择性地除去氨基保护基,然后在合成结束时的一个单一步骤中裂解所有可能存在的保护基团。为了形成肽链,利用N-羟基琥珀酰亚胺酯(-O-Su)(E.Wünsch;Synthese Von Peptiden,Vol.2.Georg Thieme Verlag,Stuttgart,1974,149页),五氟化苯酯(匈牙利专利说明书第168,431号)或混合酸酐(匈牙利专利说明书第183,579号)的方法被采用。
对于保护氨基组成部分Boc和Z基团来讲,用叔丁基,苄基或硝基苄基醇酯化的保护羟基可较佳地被采用。
合成完成后,随机存在的一个或多个保护基团从如此所获得的保护的肽中除去,如果需要的话,可通过酸处理而将游离肽转化为它的酸加成盐。为了除去保护基团,可采用催化氢化或酸解。
对于治疗来说,所得到的游离肽通常是足够纯的,并不需要任何进一步的纯化。但是,如果需要的话,它们可以通过硅胶柱层析而纯化。所得到的呈溶液形式的肽可以通过溶液的蒸发或冷冻干燥而分离。游离肽可以被转化为任选的盐,但是,用药物学可接受的酸,如盐酸,硫酸,磷酸,醋酸和柠檬酸将其转化为酸加成盐是较佳的。
所制得的化合物的免疫抑制效应通过采用下面所描述的方法来研究。
1.对于产生抗体的细胞的效应
该研究是采用从根据Canningham的方法(Handbook of Experimental Immunology,Ed,D.M.Weir,Vol.2 Blackwell,Oxford-London,p285,1978)从初生大鼠中获得的脾细胞来进行的。将同一窝的12个Wistar鼠在它们出生后12小时内,用25μg试验物质进行腹膜内(i.p.)注射。出生后第14天,用含有5%绵羊红细胞的0.5ml悬浮液对该动物进行腹膜注射(i.p.)免疫,7天后再断头放血。在由动物中获得的脾细胞中,用羊红细胞悬浮液和补体制得均相的悬浮液,然后将该悬浮液置入适宜于获得单细胞层的室中。在产生抗体的脾细胞周围形成了溶胞区,和所称的噬菌斑。表1中的数据列举了用抑制物质处理的效应。表1中所给出的形成噬菌斑的细胞的数目的变化(治疗效应)以百分数表示(从未经处理的动物中获得的细胞数目作为对照)。就已知的免疫刺激物质(见表1中化合物“A”,“B”和“C”),该百分数很明显地上升。

该研究是采用Evans等人的方法[Br.J.pharmacol.43,403(1971)],采用体重为20-22g的雄性BALB/C(LAT1)鼠来进行的。将动物腹部的毛拔去,然后,用0.1ml在葵花籽油中的2%的噁唑酮(oxazolone)溶液使每一个动物的裸露的腹部皮肤致敏。1周后,用1.0mg/kg的剂量的试验物质(溶解于生理盐水溶液中)对鼠进行腹膜内注射(i.p.)处理,然后,用10μl含2%噁唑酮的丙酮溶液直接处理动物的右耳,而用10μl丙酮处理动物的左耳。24小时后,割下它们的耳朵并称重。将经处理的和未经处理的动物耳朵的重量的差异与在分别用试验物质处理和只用生理盐水处理的动物中所观察到的差异进行比较。耳朵重量的差异被认为与接触性皮炎的程度成比例,将不用试验物质处理的动物中所测得的值作为对照,得到试验物质的减少皮炎的效应列于表4中,以百分数表示。

为了治疗应用,用本发明的肽和它们的酸加成盐可以配制成普通的药物组合物,以减少免疫系统的活性。使用这种新型化合物的优点在于它们基本上是彻底安全的,因为在所使用的剂量范围内,它们没有副作用。
分子式(1)-(16)的肽可以单独使用,或以它们的游离形式或酸加成盐形式,较合适的是以药物配方而使用。这些配方可以是固体,液体或半流体的,可以采用填料,稀释剂,稳定剂,影响pH和渗透压的作用剂以及在配方中促使该配方能作一般应用的添加剂来制备。
固体药物组合物可以是,例如粉末安瓿,适宜于制成注射用溶液。可注射的组合物和输注液是液体的。
本发明的药物组合物以含有对于获得所需要的效应所需的活性成分的剂量的量施用于病人。该剂量取决于疾病的严重性,病人的体重,病人对于活性成分的敏感性,给药的途径和每天治疗的次数。在任何情况下,所用的剂量都由了解所治疗病人的内科医生来规定。
对于一个简单的给药来说,药物组合物可以由含有一次给药的活性成分的剂量单位,或1/2,1/3或1/4或更小的剂量单位所组成。
本发明的组合物通常每个剂量单位中含有1-100mg活性成分。但是,很显然,在一些组合物中,活性成分的量可以比上述限定的值高些或低些。
本发明将通过下面的非限定实施例而详细列举。在说明中所用的缩写与在文献中[Biochem.J.219,345(1984)]通常被接受的那些相对应。根据通常的经验,“D”构型(右旋型)只在由符号给出的名称中才指明,其它氨基酸都具有“L”构型(左旋型)。熔点在Dr.Tottoli装置(由Büchi,Switzerland制造)中测定。薄层色谱检验是采用常备用吸附剂(DC-Fertigplatten,由Merck,FRG制造)和下面的溶剂混合物(这里“储备液”是吡啶/醋酸/水为20∶6∶11的混合物)来进行的:

特定的光学活性在Perkin-Elmer 241型旋光计中进行。所有的溶剂都在Büchi旋转蒸发器中,在水溶液中,40℃下除去或蒸发。
中间品和靶化合物的’H-NMR和13C-NMR核磁共振谱在Varian XLA400型装置中测定。在任何情况下,靶化合物均溶于D2O。核磁共振谱与所期望的结构相一致。
靶化合物的氨基酸分析在Biotronik LC 5001型装置中进行。样品在6摩尔浓度的盐酸中,在110℃下水解24小时。任何情况下,分析结果都在±5%的偏差极限内。
