另一方面,在咪唑盐1肯定为新颖的同时,而有些相应的酸(阴离子部分)确是已知的,例如,EP-A-45955,Ger Offen.No.2031227,2919545,2920292,日本公开专利第78-9651号,Biochem,Biophys.Res.Commun.V.101,258,1981,Biomed.Mass Spectrom,11,539,1984;然而其中没有描述它们的药理活性。
现已发现,这些已知的化合物还具有令人惊奇的优越的药理活性。
本发明的另一个目的,是提供一种含有所述已知酸作为活性成份的药用组合物,这将在以下给以特定限定。
本发明化合物的制备从5-氨基-水杨酸开始,在有适宜的碱(吡啶,三乙胺等等)存在下,溶于适当的溶剂,用等摩尔量的活化衍生物处理,例如通式为RCOOH酸的酰基氯或酸酐,其中R的定义如上。在室温或加热条件下搅拌之后,通常可获得N,O-二酰基和N-酰基产物的混合物,然后对其在极为温和的条件下对O-酰基基团进行选择性水解,以此保护N-酰基基团和酰基两者本身的性质。所述方法的特点是对酰基衍生物之混合物进行处理,从反应介质中分离出来并溶于适宜的溶剂中,使用催化量的咪唑碱,并有少量的水存在。在室温搅拌后,其时间因考虑的酰基而不同,对N-酰基衍生物的回收,是由蒸发除去溶剂,然后在适宜的溶剂中重结晶而完成的。
咪唑盐或取代的咪唑盐,以及药理上可接受的金属盐或其他有机碱的盐,是通过把等摩尔量的相应的酸和碱在适宜的有机溶剂中相混合而制备的,盐的回收,可以从反应介质中直接沉淀出来,也可真空蒸发除去溶剂而得,又可由向介质中加入可混溶的沉淀剂而完成。

生物学活性
对此前所述化合物进行了体外及体内分析的实验,目的在于证实它们潜在的生物学活性。
大豆脂肪氧合酶的抑制活性
这一分析使得表明对被认为是人类酶的一种的大豆脂肪氧合酶具有抑制活性。在哺乳动物中,这种酶系统促进花生四烯酸在3-(1,3,5,8-十四碳四烯基)-环氧乙烷丁酸和5,12-二羟基-6,8,10,14-二十碳四烯酸(Leukotriene A4和B4)中的转化。这些化合物被认为是对炎症负有主要责任。即Leukotriene A4和B4在肠炎病和克罗恩氏病中,表现出了相应的前期-炎症活性(Pro-iflammatory actirity)。
大豆脂肪氧合酶(E·C·1131012)已根据Axelrod等人(Axelrod B·-Cheesbrough T·H·,Laa Ksos·in Methods in Eezy Mology,Vol·71,Page·441,1981-Academic Press N·Y)的方法,于室温下,对有被分析产物和没有被分析物存在的情况进行了分析,以正二羟愈疮酸为参考。

对血小板凝集和凝血恶烷A2的产生的活性
测试在体外进行,使用从新西兰兔中获取的柠檬酸化的富含血小板的血浆(P·P·P)。血小板凝集是根据Born(Born G·V·R·-Nature,Vol,162,67)的方法进行的,使用0,25mM的花生四烯酸作为凝集剂。
抑制活性以半数有效量(ED50,以毫摩尔计)计算,即抵销50%花生四烯酸凝集效力的剂量。
对凝血恶烷A2的产生,是根据Moncada等人(Moncadas,,Ferreira S·H·,Vane,J·R·-Adv·Throm-boxanes Res·-Frolieh J·C·ED·,Vol·5,211,1978-Raven Press)的生物分析方法测定的。在加入花生四烯酸后的预定时间,在兔主动脉螺旋条和鼠胃底条组成的组织序列(串联序列)上,使用生物分析方法对200微升P·P·P测定其凝血恶烷A2的生产和类似前列腺素活性。
受试化合物对凝血恶烷A2生产的抑制活性以半数有效量表示(ED50),即能够降低凝血恶烷A2(TXA2)对组织缩效应的浓度。
将受试化合物溶于吐温80(Tweew80),并加入P·R·P·,逐渐增加浓度,直至测定出ED50时为止。

2-鼠爪阿尔图斯氏反应的被动保留(免疫炎症)
分析按Gemmel等人(Gemmel D·K·Cottney J·Lewis A·J·-Agents Actions,Nol·9,107,1979)的方法进行。1毫升鼠抗牛清血蛋血清(冻干抗体,溶于2毫升0.9%盐水中)注射到Sprague-Dauley雄鼠的尾静脉中。
在牛清蛋白处理前的3小时,口服受试化合物。对鼠爪体积增长的抑制百分率(%),对照未处理动物爪体积的增长而计算。某些本发明化合物的结果见于表5。

3-鼠的乙酸肠炎(非免疫肠炎)
测试按Sharon(Sharon P·,Stenson W·F·-Gastroen-terology,Vol·88,55,1985)的方法进行。
考虑到测试的性质,本试验主要测定那些从前边试验的结果已知其吸收不好的化合物。然而,应当注意的是,所有描述过的衍生物,对肠炎和克罗恩氏病的诊治均很有用。
结果见下表6:
给药量(通过肠内,在肠结扎和局部注射乙酸期间)对所有受试化合物量均为0.5mM/kg,溶于羧甲基纤维素中。溃疡的降低指数对照未处理动物计算。

急性中毒
表1中的化合物,在小鼠中进行了急性中毒试验,口服溶于羧甲基纤维素的悬浮液。所有的半数致死量均被证明是高于1600mg/kg。
本发明还涉及与使用化合物1和相应的游离酸作为诊治剂有关的全部工业领域。本发明的一个基本的方面是提供药用组合物,其含有预定的并有效治疗量的上述化合物中的至少一种作为活性成份,以及常规的赋形剂和(或)载体。
本发明的组合物,可以服用的方式有口服,肠胃外服用,直肠或局部服用,例如可以使用片剂,胶囊,糖浆,小药囊,溶液,小瓶,瓶装剂,栓剂等等形式。
给药量可以根据患者的体重,年龄和条件等而变化,范围在50-1000mg之间,每天1-4次。
