2-substituted-6-(dimethylamino)-9-(4-methylbenzyl)-9H-purines where the 2-substituent was H, F, Cl, CF3, CH3, CH2CH3, NH2, NHCH3, N(CH3)2, SCH3, or SO2CH3 was synthesized and tested for antirhinovirus activity to evaluate the effect of 2-substituents on antiviral activity. Intuitive and quantitative structure-activity relationship (QSAR) analysis showed that optimum antirhinovirus serotype 1B activity was associated
一系列2-取代的6-(二甲氨基)-9-(4-甲基苄基)-9H-嘌呤,其中2个取代基是H,F,Cl,CF3,CH3,CH2CH3,NH2,NHCH3,N(CH3)如图2所示,合成SCH3或SO2CH3并测试其抗鼻病毒的活性,以评估2-取代基对抗病毒活性的影响。直观和定量的结构-活性关系(QSAR)分析表明,最佳的鼻病毒性血清型1B活性与包含C-2亲脂性,吸电子取代基的9-苄基嘌呤有关。活性最高的化合物6-(二甲基氨基)-9-(4-甲基苄基)-2-(三氟甲基)-9H-嘌呤(14)对1B型血清型的IC50 = 0.03 microM,但对18种其他血清型的活性为不均匀 IC50的范围超过260倍。
