hexamethylenetetramine. One of the Tröger's base analogs, 2,8-bis(3'-pyridylmethyl)-6H,12H-5,11-methanodibenzo[b,f][1,5]d iazocine (5), is an effective inhibitor of the enzyme, thromboxane A2 (TxA2) synthase, with an ED50 of 30 ng/mL in a specified in vitro assay. Three analogs having substituents on the bridging methylene group of the bicyclic nucleus of the Tröger's base structure were prepared, but all were
由对甲苯胺合成2,8-二甲基-6H,12H-5,11-甲二苯并[b,f] [1,5]重氮(Tröger's碱)和其他苯胺的两个Tröger's碱类似物与六亚甲基四胺的反应在三氟乙酸中有描述。2,3,6,7-四氢-9-甲基-2,6-二-对-甲苯基-1H,5H-嘧啶基[5,6,1-ij]喹唑啉在p的反应中形成为副产物-甲苯胺和六亚甲基四胺。Tröger的基本类似物之一,2,8-双(3'-吡啶甲基)-6H,12H-5,11-甲二苯并[b,f] [1,5] d咪唑啉(5)是有效的抑制剂。酶,血栓烷A2(TxA2)合酶,在指定的体外测定中ED50为30 ng / mL。制备了在Tröger基本结构的双环核的桥连亚甲基上具有取代基的三个类似物,但在抑制试验中,它们的活性均明显低于上述化合物。这些TxA2合酶抑制剂的结构不属于针对此类酶抑制剂建立的经典结构-活性关系。
