Exploration of the SAR around selective NK2 antagonists, SR48968 and ZD7944, led to the discovery that naphth-1-amide analogues provide potent dual NK1 and NK2 antagonists. ZD6021 inhibited binding of [3H]-NKA or [3H]-SP to human NK1 and NK2 receptors, with high-affinity (K(i)=0.12 and 0.62nM, respectively). In functional assays ZD6021 had, at 10(-7)M, in human pulmonary artery pK(B)=8.9 and in human
对选择性NK2拮抗剂SR48968和ZD7944周围SAR的探索导致发现萘1酰胺类似物可提供有效的NK1和NK2双重拮抗剂。ZD6021抑制[3H] -NKA或[3H] -SP与人NK1和NK2受体的结合,并具有高亲和力(分别为K(i)= 0.12和0.62nM)。在功能测定中,对于人NK1和NK2,ZD6021在10(-7)M时的人肺动脉pK(B)= 8.9和人支气管pK(B)= 7.3。对豚鼠口服ZD6021剂量依赖性减弱ASMSP诱导的血浆蛋白外渗,ED(50)= 0.5mg / kg,NK2介导的支气管收缩,ED(50)= 13mg / kg。
