A series of substituted phenyl analogues of 5-[[4-(4,5-dihydro-2-oxazolyl) phenoxy]alkyl]-3-methylisoxazoles has been synthesized and evaluated in vitro against several human rhinovirus (HRV) serotypes. Substituents in the 2-position greatly enhanced activity when compared to the unsubstituted compound. Many of these compounds exhibited mean MICs (MIC) against five serotypes as low as 0.40 microM.
已经合成了一系列5-[[[4-(4,5-二氢-2-恶唑基)苯氧基]烷基] -3-甲基异恶唑的取代苯基类似物,并在体外针对几种人鼻病毒(HRV)血清型进行了评估。与未取代的化合物相比,位于2位的取代基大大提高了活性。这些化合物中的许多都表现出针对低至0.40 microM的五种血清型的平均MIC(MIC)。平均MIC与MIC80(抑制80%所测试血清型的浓度)相关性很好(r = 0.83)。定量结构-活性关系研究表明,MIC与亲脂性(log P)以及诱导效应(sigma m)和体积因子(MW)密切相关。
