elements, α,β-diketo acid moiety and substituted aryl ring. In this study, as a part of our ongoing efforts to discover a novel anti-HCV compound mimicking the ADK scaffold, we designed 2-arylmethylaminomethyl-5,6-dihydroxychromone derivatives of which the dihydroxychromone moiety as well as the arylmethylaminomethyl substituent (R-PhCH2NHCH2–) were anticipated in exact match with the pharmacophore model
芳基二酮酸(ADK)的抗HCV活性已通过其两个药效学元素(α,β-二酮酸部分和取代的芳基环)进行了表征。在这项研究中,作为我们不断努力探索模仿ADK支架的新型抗HCV化合物的一部分,我们设计了2-芳基甲基氨基甲基-5,6-二羟基色酮衍生物,其中的二羟基色酮部分以及芳基甲基氨基甲基取代基(R-预计PhCH 2 NHCH 2 –)与ADK的药效团模型完全匹配。如此制得的二羟基色酮衍生物(3a – 3u)以取代基依赖性方式表现出生物活性,从而导致选择性的抗HCV效应(EC 50 = 2.0–14.0μM,CC 50 > 100μM),尤其在芳环的3位带有取代基,如Cl,Br,I和Me。
