Abstract A series of novel chalcone derivatives containing purine moiety was designed and synthesized, and their antiviral activities against cucumber mosaic virus (CMV) and tobacco mosaic virus (TMV) were evaluated in vivo. Bioactivity assays indicated that some compounds showed good antiviral activities against CMV and TMV. It is worth mentioning that compounds 3o, 3s, 3w, and 3x exhibited excellent
摘要设计合成了一系列含有嘌呤部分的查耳酮衍生物,并对其体内对黄瓜花叶病毒(CMV)和烟草花叶病毒(TMV)的抗病毒活性进行了评价。生物活性测定表明,某些化合物对CMV和TMV表现出良好的抗病毒活性。值得一提的是,化合物3o,3s,3w和3x表现出优异的抗CMV活性,EC50值分别为301.1μg/ mL,315.7μg/ mL,282.3μg/ mL,230.5μg/ mL,更好高于Dufulin(373.7μg/ mL)和Ribavirin(726.3μg/ mL)。另外,荧光光谱实验结果表明,化合物3o对烟草花叶病毒外壳蛋白具有很强的结合能力。
