A series of arylidene imidazo[2,1-b]thiazoles was synthesized, in order to investigate the influence of different spatial arrangements of the arylidene substituent towards the bicyclic structure of imidazo[2,1-b]-thiazole on benzodiazepine receptor affinity. 1,2- And 2,3-cyclized derivatives of mono- and di-substituted Z-5-arylidene-2-thiohydantoins were investigated. As an example of E isomers E-5-benzylidene-2
一系列亚芳咪唑并[2,1- b ]噻唑的合成,为了研究的亚芳基的取代基的空间排列不同朝向咪唑并[2,1-的双环结构的影响b〕噻唑于苯并二氮杂受体的亲和力。1,2-和2,3-环化的衍生物的单-和二-取代的Z-5-亚芳基-2- thiohydantoins进行了调查。作为一个例子ë异构体Ë -5-亚苄基-2,3-二氢咪唑并[2,1- b ]噻唑-6(5 ħ)-获得了一个。亚芳基取代基朝向双环结构的空间排列以及异构体的特性对化合物的苯并二氮杂receptor受体亲和力影响很小。似乎对生物活性的最大影响是苯环上取代基的性质和数量。所有研究的咪唑并[2,1- b ]噻唑较先前所描述的亚芳基咪唑并[2,1-活性较低b ] thiazepinones。
