产品描述:
Fipronil-13C2,15N2 is intended for use as an internal standard for the quantification of fipronil (Item No. 24128) by GC- or LC-MS. Fipronil is an insecticide that acts as a selective antagonist of insect GABA receptors (IC50s = 28 and 1,660 nM for cockroach and rat receptors, respectively).{41694} It also inhibits desensitizing and non-desensitizing glutamate-induced chloride currents in cockroach neurons (IC50s = 800 and 10 nM, respectively). Fipronil induces activity of the cytochrome P450 (CYP) isoforms CYP1A1/2, CYP2B1/2, and CYP3A1/2 in isolated rat liver microsomes.{41695} Formulations containing fipronil have been used as insecticides in veterinary care.
