A series of novel 1,3,4-oxadiazole/thiadiazole–chalcone conjugates were synthesized and their in vitro and in vivo antiviral activities were evaluated via microscale thermophoresis method and half-leaf method, respectively. The in vitro results indicated that compounds 7g, 7l, 8h, and 8l displayed good antiviral activity against TMV, with the binding constant values of 5.93, 6.15, 6.02, and 5.04 μM
合成了一系列新型的1,3,4-恶二唑/噻二唑-查耳酮共轭物,并分别通过微型热泳法和半叶法评估了它们的体外和体内抗病毒活性。体外结果表明,化合物7g,7l,8h和8l对TMV表现出良好的抗病毒活性,结合常数分别为5.93、6.15、6.02和5.04μM,与Ninnanmycin(6.78μM)相当),甚至比利巴韦林(99.25μM)更好。体内结果表明,化合物7g,7l,8h和8l表现出显着的抗TMV活性,EC 50值分别为33.66、33.97、33.87和30.57 µg / mL,与宁南霉素(36.85 µg / mL)相当,并且优于利巴韦林(88.52 µg / mL)。 。有趣的是,体内抗病毒活性的趋势与体外结果一致。
