Here, a series of β-amino acid ester derivatives containing quinazoline and benzothiazoles was synthesized and evaluated for anti-tobacco mosaic virus (TMV) activity. The compounds 3n, 3o, 3p and 3q showed good antiviral activity against TMV at a concentration of 500 μg/mL, with curative rates of 55.55%, 52.32%, 52.77% and 50.91%, respectively, and protection rates of 52.33%, 55.96%, 54.21% and 50.98%, respectively. These values were close to those of the commercially available antiviral agent ningnanmycin (which has curative and protection rates of 55.27% and 52.16%, respectively). To our knowledge, this is the first report of the anti-TMV activity of β-amino acid ester derivatives containing quinazoline and benzothiazoles moieties; the results indicate that these novel compounds can potentially be used as protective agents against TMV diseases.
