A series of (2-benzoylethen-1-ol)-containing benzothiazine derivatives was synthesized, and their herbicidal activities were first evaluated. The bioassay results indicated that some of 3-benzoyl-4-hydroxy-2-methyl-2H-1,2-benzothiazine-1,1-dioxide derivatives displayed good herbicidal activity in greenhouse testing, especially, compound 4w had good pre-emergent herbicidal activities against Brassica campestris, Amaranthus retroflexus and Echinochloa crusgalli even at a dosage of 187.5 g ha-1. More importantly, compound 4w displayed significant inhibitory activity against Arabidopsis thaliana HPPD and was identified as the most potent candidate with IC50 value of 0.48 μM, which is better than the commercial herbicide sulctrione (IC50 = 0.53 μM) and comparable with the commercial herbicide mesotrione (IC50 = 0.25 μM). The structure-activity relationships was studied and provided some useful information for improving herbicidal activity. The present work indicated that (2-benzoylethen-1-ol)-containing 1,2-benzothiazine motif could be a potential lead structure for further development of novel HPPD inhibiting-based herbicides.
