The synthesis and antiulcer activity of highly strained cage compounds such as pentacyclo[4.2.0.0(2,5).0(3,8).0(4,7)]-octane (cubane), pentacyclo[4.3.0.0(2,5).0(3,8).0(4,7)]nonane (homocubane) and pentacyclo[5.3.0.0(2,4).0(3,6).0(5,8)]decane are described. Of the compounds obtained, N-[3-(3-piperidinomethylphenoxy)propyl]-4-piperidinocarbonylpen tacyclo [4.2.0.0(2,5).0(3,8).0(4,7)]octane carboxamide
五环[4.2.0.0(2,5).0(3,8).0(4,7)]-辛烷(古巴),五环[4.3.0.0(2)等高应变笼状化合物的合成和抗溃疡活性,5).0(3,8).0(4,7)]壬烷(均苯)和五环[5.3.0.0(2,4).0(3,6).0(5,8)]癸烷是描述。在获得的化合物中,N- [3-(3-哌啶基甲基苯氧基)丙基] -4-哌啶基羰基五环[4.2.0.0(2,5).0(3,8).0(4,7)]辛烷甲酰胺(26a )和N- [3'-(3'-哌啶子基甲基苯氧基)丙基] -1-溴-9,9-乙撑二氧基五环[4.3.0.0(2,5).0(3,8).0(4,7)[壬烷] -4-羧酰胺e(26q)在HCl。乙醇处理的大鼠模型中显示出更强的抗溃疡活性,并具有非常好的细胞保护能力。化合物26a和26q的H2受体拮抗剂效能(体外)与雷尼替丁相当,但在观察到抗溃疡和细胞保护活性的剂量范围内口服给药时,在胃瘘大
