Separation, interconversion, and insecticidal activity of the cis- and trans-isomers of novel hydrazone derivatives


, : Separation, interconversion, and insecticidal activity of the cis- and trans-isomers of novel hydrazone derivatives. Journal of Separation Science 36(3): 602-608

A series of cis- and trans-isomers of hydrazone derivatives were separated and analyzed through HPLC with diode-array detection and HPLC-MS/MS using ESI and ion trap MS. Two single crystals (A-5-1 and C-2-1) of the trans-isomers were obtained and determined using X-ray crystallography data, and the cis- to trans-isomerization under different conditions was discussed. Both of the cis- and trans-isomers of A-4 and A-5 exhibited good insecticidal activities against Plutella xylostella.

According to the authors, C. septicum infection causing 5.0 to 5.2% mortality is reported for the first time in the literature from 6-week-old growing geese in 3 flocks comprising 5200, 5500 and 5900 geese, respectively. The affected birds exhibit...

The quality of analgesia, subjectively assessed, was good w...
