2-ethoxyacetylamide derivative (V-A-12, EC50 = 0.66 mg·L−1) exhibited the highest potency in vitro and superior fungicidal activity compared with procymidone (EC50 = 1.06 mg·L−1). In vivo bioassay indicated that compound V-A-12 could be effective for the control of tomato gray mold. Moreover, the structure-activityrelationship of these sulfonamides was analyzed by establishing a three-dimensional quantitative structure-activity
A series of novel thiazole acrylonitrile derivatives was designed and synthesized utilizing NC‐510 as a precursor. Their structures were characterized by NMR spectrometry, MS, and elemental analysis. The results of bioassay indicated that some of these title compounds exhibited 100% mortality at 50 mg/L against Aphis fabae. In particular, the compound 11c displayed the best activity: Its LC50 value
