The antiviral activities against tobacco mosaic virus（TMV） and cucumber mosaic virus（CMV） in vivo were evaluated. Some of the derivatives displayed promising curative effect and protective activity against TMV. Compound D5 showed appreciable curative bioactivity on TMV approximately of 50% at 306.2 mg/m L, which was superior to ningnanmycin（409.3 mg/m L）.展开更多
