Description

一类三环化合物、制备方法及其医药用途 技术领域
本发明涉及药物化学领域,具体涉及一类三环化合物、制备方法及其医药用途,本发明的化合物与现有技术相比,具有显著的抗组胺活性、极低的抑制胆碱和极低的hERG毒性的作用,本发明还提供了其在制备预防和治疗过敏性疾病药物中的用途。
背景技术
过敏性疾病如急性荨麻疹、慢性特发性荨麻疹、过敏性鼻炎、过敏性眼炎、过敏性皮肤病(包括湿疹、玫瑰糠疹、药疹、夏季皮炎、接触性皮炎、特应性皮炎)、过敏性紫癜、花粉过敏、支气管哮喘等,极大的降低了人们的生活质量。目前,用于临床上治疗这类疾病主要是以抗组胺药和免疫抑制剂为主。
其中抗组胺药物以H 1受体拮抗剂为主,H 1受体拮抗剂可竞争性地与H1受体结合而阻断组胺与H 1受体的作用,进而抑制组胺发挥生物学效应,起到抗过敏的作用[Zolaly MA.Histamine H 1antagonists and clinical characteristics of febrile seizures[J].Int J Gen Med.2012,5:277-281]。目前临床常用的组胺H1受体拮抗剂主要分为两代,第一代抗组胺药包括氯苯那敏、苯海拉明、羟嗪等,都具有显著的中枢系统副作用,容易导致嗜睡、精神恍惚。第二代抗组胺药如特非那定、氯雷他定、地氯雷他定、阿司咪唑等,虽然改善了第一代抗组胺药物的中枢系统副作用,但是部分化合物存在严重的心脏毒性如特非那定和阿司咪唑,会引起心律失常、心电图出现Q-T间期延长,甚至出现心跳骤停及猝死。其他药物如氯雷他定、地氯雷他定等,虽然未见明显的心脏毒性,但是存在明显的抑制胆碱的副作用,如口干,眼睛干涩,严重会引起运动功能障碍。
因此,开发新的具有更高安全性的H 1受体阻断剂,改善现有治疗药物的不足,降低中枢、心脏毒性和胆碱抑制活性,具有重要的价值。
本发明人申请的中国专利CN107602534B中公开了一系列具有抗组胺和抗炎双重活性的地氯雷他定衍生物,其中化合物LHC-7活性最佳,
Figure PCTCN2021090073-appb-000001
但是在随后的研究中发现其具有很强的hERG毒性(hERG钾离子通道的抑制强,具有心脏毒性风险)。
本发明人申请的中国专利CN109096251A中公开了一类多靶点地氯雷他定衍生物,包括化合物LP-2。
Figure PCTCN2021090073-appb-000002
Figure PCTCN2021090073-appb-000003
世界专利WO9200293A1中也公开了一系列的抗组胺化合物,其中包括以下结构的化合物1:
Figure PCTCN2021090073-appb-000004
但该世界专利中未公开化合物1的实施方法、活性数据等。
本发明在现有技术的基础上研究开发了一系列新的化合物,并发现这些化合物表现出优异的效果和作用。尤其是本发明化合物既保留了显著的抗组胺的活性,同时比地氯雷他定、LHC-7、LP-2、化合物1的抗胆碱活性更低,hERG毒性更低,本发明化合物具有更高的安全性。
