this series whilst the presence of hydroxy or methoxy substituents seems to be negligible. In the naphthyl series, both the basicity and the presence of H-bond donor or acceptor groups seem to be negligible. Moreover, the lipophilicity did not influence the P-gp inhibition activity of each series. Specific biological assays have been carried out to establish the P-gp interacting mechanism of tested
从铅化合物1(EC(50)= 1.64 microM)开始,其非碱性核已在构象上受到4-联苯和2-萘基部分的限制。在每个系列中,我们研究了H键供体或受体取代基,碱度和亲脂性(clogP)的存在是否与受试化合物的P-gp抑制活性相关。在联苯系列中,衍生物4d表现出最好的结果(EC(50)= 0.05 microM)。发现相应酰胺3d的活性较低(EC(50)= 3.5 microM),确定碱性在该系列中的重要性,而羟基或甲氧基取代基的存在似乎可以忽略不计。在萘系列中,碱度和氢键供体或受体基团的存在似乎都可以忽略不计。此外,亲脂性不影响每个系列的P-gp抑制活性。已经进行了特定的生物学测定,以建立区分底物和抑制剂的被测化合物的P-gp相互作用机制。而且,化合物4d表现出有效的P-gp抑制活性,并且对BCRP泵具有良好的选择性。
