Bioactivity assays showed that most of the target compounds exhibited moderate to good antiviral activity against tobacco mosaic virus（TMV） at 500 mg/m L. Among the target compounds,compound 7h showed the highest in vivo inactivation activity against TMV with the EC50 and EC90value of 45.6 and 327.5 mg/m L, respectively, which was similar to that of Ningnanmycin（46.9 and 329.4 mg/m L）and superior to that of Ribavirin（145.1 and 793.1 mg/m L）. Meanwhile, the microscale thermophoresis and fluorescence spectroscopy experiments showed that the compound 7h had a strong interaction with the tobacco mosaic virus coat protein.展开更多
