dicarboxylate 42 displayed intermediate affinity and enhanced aqueous solubility. Isoquinuclidine 34 (IC50 15.6 nM) and isonortropanol 30 (IC50 21.3 nM) had lower lipophilicity than 1. In general, rigidified piperidine derivatives did not lower lipophilicity dramatically, except those rings with multiple polar groups. P2Y14R molecular modeling based on a P2Y12R structure showed stable and persistent key
高亲和力苯基哌啶 P2Y 14 R 拮抗剂1 (PPTN) 用哌啶桥接部分进行修饰,以探测受体亲和力和疏水性。各种 2-azanorbornane、nortropane、isonortropane、isoquinuclidine 和开环环戊基氨基衍生物保留了人 P2Y 14 R 亲和力(荧光结合测定),并比较了它们的药效团叠加。对映体 2-azabicyclo[2.2.1]hept-5-en-3-one 前体确保了立体化学明确的多样化产品。纯 ( S , S , S ) 2-azanorbornane 对映体15 (MRS4738) 显示出比1更高的亲和力(比对映体16高 3 倍亲和力)) 和体内抗超痛和抗哮喘活性。它的双前药143 (MRS4815) 显着减少了小鼠哮喘模型中的肺部炎症。相关的内酰胺21 – 24和二羧酸盐42显示出中等亲和力和增强的水溶性。异奎宁环34 (IC 50 15
