Phenylpyrazole ethiprole
WebEthiprole differs from fipronil, the major phenylpyrazole insecticide, only in an ethylsulfinyl substituent replacing the trifluoromethylsulfinyl moiety. This study compares their photochemistry, metabolism, action at the gamma-aminobutyric acid (GABA) receptor, and insecticidal potency. WebNov 11, 2015 · R-Ethiprole to S-ethiprole transformation was observed, but not S-ethiprole to R-ethiprole. No enantioselective metabolism was observed for flufiprole with the EF values of 0.49–0.51.
