agents led to the synthesis of compound 8, 2-[4-[4-[bis(4-fluorophenyl)methyl]-1-piperazinyl]-4, 4a,5,5a,6,6a-hexahydro-4,6-ethenocycloprop[f]isoindole-1,3(2H,3 aH)-dione, which demonstrated good H1-antagonist activity. Substitution of a xanthinyl moiety for the polycyclic imide group led to the identification of novel xanthinyl-substituted piperazinyl and piperidinyl derivatives with potent antihistamine
多环哌嗪基酰亚胺5-羟色胺能剂的结构操纵导致化合物8、2- [4- [4- [双(4-(氟代苯基)甲基] -1-哌嗪基] -4],4a,5、5a,6、6a的合成-六氢-4,6-乙炔环丙[f]异吲哚-1,3(2H,3 aH)-二酮,具有良好的H1拮抗剂活性。用黄嘌呤基部分取代多环酰亚胺基团导致鉴定出具有强抗组胺H1活性而没有8的不希望的抗多巴胺能活性的新型黄嘌呤基取代的哌嗪基和哌啶基衍生物。一种化合物24、7- [3- [4-] (二苯甲氧基)-1-哌啶基]丙基]-3,7-二氢-1,3-二甲基-1H-吡啶-2,6-二酮(WY-49051)是一种有效的口服活性H1拮抗剂,具有较长的持续时间和良好的中枢神经系统特征。
