Abstract

本发明有关羟基-4-2H-1-苯并噻喃-2-酮,用下式表示:
其中当R1是氢时,R与AR′可以形成一个四氢萘环基;当R1是氢时,R是一个羟基;AR是一个被卤素取代或未取代的联二苯基或苯氧基苯基,而AR′是一个被取代或未取代的苯基,它可以与R形成一个四氢萘环基或一个噻吩基。
这些化合物具有一系列有趣的性质,特别是可以利用来作杀鼠剂。

Description

本发明有关式(Ⅰ)所示的羟基-4-2H-1-苯-并噻喃-2-酮及它们的制备和含有它们的组合物。
这些化合物用下式表示:
Figure 85103105_IMG6
其中R可以是与AR′结合成四氢萘环基;当R1是氢时,R和R1可以是羰基;当R1是氢时,R可以是一个羟基;AR可以是一个被卤素取代或未取代的联二苯或苯氧基苯,AR′是一个取代或未取代的苯基,它可以与R成为一个四氢萘环基或一个噻吩基。
这些化合物可以根据下述的一个或另外的方法制备。
当式(Ⅰ)中的RR1=0时,产物是由羟基-4-2H-1-苯并噻喃-2-酮与式(Ⅱ)化合物反应得到:
Figure 85103105_IMG7
这个反应在有溶剂如:乙醇、二噁烷等,与一个缩合剂哌啶存在下,沸腾若干小时。
当式(Ⅰ)中R=H、R1=OH时,用甲醇、二甲基甲酰胺或二者之一与水混合液作溶剂,借助氢硼化钠还原而得到这类化合物。其中式(Ⅰ)的化合物RR1=O。
当R与AR′是一个四氢萘环基和R1是氢时,式(Ⅰ)中相应的化合物是羟基-4-2H-1-苯并噻喃-2-酮与下式的化合物反应制备的:
Figure 85103105_IMG8
反应在含硫酸的醋酸溶剂中于20℃-150℃间进行。
当R=OH或R和AR′是一个四氢萘环基,和R1是氢时,这类化合物以一种非对映异构体的混合物形式存在,这在薄层层析或高压液相层析中显示出来。
本发明的产品具有很多令人感兴趣的性质。特别是作为抗凝固剂的作用,这在杀野生鼠(学名:Rattus    Norvegious)试验中充分显示出来。
为此,含剂量50ppm被研究物的淀粉和面粉混合物作为诱饵测试。每3天喂成年雄的或雌的鼠一次这种诱饵。通过测定其死亡率来检验其效率。结果见下面表Ⅰ中。
表    Ⅰ
Figure 85103105_IMG9
(杀鼠灵(Coumafēne)=羟基-4-(苯基-1-氧代-3-丁基)-3-2H-1苯并噻喃-2-酮)
这些化合物只处理一天也导致大鼠100%地死亡。这在下面的表Ⅱ中已示。
另一方面,经试验证实本发明的噻喃衍生物(如:式Ⅰ)优于相应的吡喃衍生物,显示出意想不到的效果。事实上,已经知通了在3位上被
表    Ⅱ
Figure 85103105_IMG10
取代的羟基-4-香豆素衍生物是一类具有很强抗维生素K效能,从而被用来作杀鼠剂。门茨尔(Mentzer)的工作(生化简报25期,379-383页Bull.Soc.Chim.Biol.25.Pages    379-383,1943)从另一个角度指出:败坏翘摇素(dico-umarol)的杂环中的氧被硫代替后生成了一个不活泼的产物。这结果已为杀鼠灵(coumafēne)和它的含硫同系物硫杀鼠灵所证实。下面表Ⅲ再汇集其结果。
表    Ⅲ
根据例1,与其含氧相等量的(A)比较,(溴-4′-联二苯-4)-3,四氢-1-2-3-4-萘基-1)-3,羟基-4,2H-1-苯并噻喃-2-酮有明显优于A的活性。对Rattus    rattus(一种能抗杀鼠灵的品系);Mus    musculus(一种对杀鼠灵敏感的品系)和另一种Mus    musculus(一种抗杀鼠灵的品系)进行药物试验,其结果见下列三个表:
Figure 85103105_IMG12
上述表中的读数表明与分子式(Ⅰ)相应的化合物,由于有苯并噻喃环与其它苯并吡喃相比有较高的活性。
另一个意想不到的效果就是本发明的化合物与它们含氧的同系物相比毒性要小。特别是对非啮齿动物毒性要小。作为例子,下面叙述一个在小猎兔犬(Beagle)上的试验:
给三只猎犬每日口服50μg/kg的例1化合物,另一组三个猎犬以同样方式每日用同样剂量的化合物A。生物检查就是与达到300秒存活时间之对照的存活时间(le    temps    de    Quick)。图1的曲线表示猎犬存活时间延长的效果。以秒为单位的存活时间作为纵轴(TQs),以天为单位的药物处理时间作为横轴(j)。曲线1,2和3为化合物A的效率;4,5,6为化合物1的效率。字母M为动物死亡的时间。
而且,用化合物A处理犬的试验表明,随着存活时间的增加,犬死亡也很快,以致于无法解毒抢救。相反对化合物1,存活时间增加和临床状态的恶化都是逐渐进行的。当存活时间达到300秒时,我们有时就用一种古典的治疗方法,用维生素K来抢救。可以用口服来代替5mg/kg的静脉注射。三只犬的情况表明经过抢救存活时间又很快地最终回到正常值上来。
本发明的化合物,特别是例1的化合物组成了杀鼠剂成分中的抗凝结活性物质,而与被啮齿类可消耗的一种载体物质结合。
下面举例说明,但本发明并不受此限制。例1:〔(溴-4′-联二苯基-4)3-四氢-1,2,3,4-萘基-1〕-3,羟基-4,2H-〔1〕-苯并噻喃-酮-2.C31H23BrO2S(式1),分子量=539、34。
