quinoline-based human H1 and H3 bivalent histamine receptor antagonists, suitable for intranasal administration for the potential treatment of allergic rhinitis associated nasal congestion, were identified. Compound 18b had slightly lower H1 potency (pA2 8.8 vs 9.7 for the clinical goldstandard azelastine), and H3 potency (pKi 9.1vs 6.8 for azelastine), better selectivity over α1A, α1B and hERG, similar
鉴定了一系列新颖的基于喹啉的有效人H1和H3二价组胺受体拮抗剂,适用于鼻内给药,可用于治疗变应性鼻炎相关的鼻充血。化合物18b的H1效力(临床金标准氮卓斯汀的pA2 8.8与9.7)和H3效力(氮卓斯汀的pKi 9.1vs 6.8)略低,选择性比α1A,α1B和hERG好,作用时间相似,因此18b的背甲好到我们之前的候选人,但具有更理想的配置。
