Several novel substituted tetrahydro- and hexahydro-1,2-benzisothiazol-3-one 1,1-dioxides and thiadiazinones were prepared and examined in a series of in vitro and in vivo tests to determine their pharmacological profile. Most compounds were orally active in blocking the conditioned avoidance response (CAR) but did not antagonize apomorphine-induced stereotyped behavior. Several compounds demonstrated
制备了几种新颖的取代的四氢-和六氢-1,2-苯并噻唑-3-一和1,1-二氧化物和噻二嗪酮,并在一系列体外和体内试验中进行了研究,以确定它们的药理作用。大多数化合物在阻止条件性回避反应(CAR)方面具有口服活性,但不能拮抗阿扑吗啡引起的刻板印象。几种化合物对5-HT1A受体的结合位点表现出中等至高的亲和力,其中含有2-嘧啶基哌嗪基和[3-(三氟甲基)苯基]哌嗪基部分的化合物37和38和含有2-吡嗪基哌嗪基部分的化合物47表现出最高的亲和力( Ki值分别为10、4和9 nM。化合物37,3- [4- [4-(2-嘧啶基)-1-哌嗪基]丁基]六氢-4,7-乙炔基-1H-环丁[[f] -1,2-苯并噻唑-3(2H)- 1,1-二氧化物 丁螺环酮和ipsapirone的神经化学和行为特征相似。它们在阻断CAR方面的功效相似,AB50分别为39、32和42 mg / kg。他们还显示了对5-HT1A受体位点的高亲和力和选择性(Ki
