A series of novel (1E, 4E)-1-aryl-5-[2-(quinazolin-4-yloxy)phenyl]-1,4- pentadien-3-one derivatives were designed and synthesized by reacting substituent aldehyde with intermediates 4a-f. Antiviral bioassays indicated that most of the compounds exhibited promising ex vivo antiviral bioactivities against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) at 500 μg/mL. The relationship between structure and antiviral activity was also discussed. Compounds 5a, 6e, and 6g could possess appreciable protective bioactivities on TMV ex vivo by approximately 50% (EC50) at 257.7, 320.7 and 243.3 μg/mL. This study is the first to demonstrate that (1E, 4E)-1-aryl-5-(2-(quinazolin-4-yloxy)phenyl)-1,4-pentadien-3-one can be used to develop potential virucides for plants.
