Development of chromatographic / electrophoretic methods to be further applied in in vitro enzymatic inhibition studies and prediction of drug interactions of chiral pesticides - Phase 2

Abstract

Quantification of analytes present in biological matrices requires the development of methods that are accurate and reproducible under various analytical conditions. Chromatographic and electrophoretic techniques (capillary electrophoresis) are techniques widely used for these purposes. These techniques have the main advantage of simplicity, rapid analysis and wide versatility. Our research group has been working on the development and validation of chromatographic and electrophoretic methods to be further applied in studies of in vitro metabolism and biotransformation involving chiral drugs as well as natural products. In this new proposal, we have the objectives of continuing the previously initiated project (FAPESP 2016/07597-0), which expires on 07/30/2018. In this new project we will evaluate the chiral pesticides tebocunazol, ethofumesate and diclofop-methyl. The main objective is the determination of enantioselectivity in the in vitro metabolism of these chiral pesticides and subsequent in vitro studies of enzymatic inhibition, phenotyping and prediction of drug interactions. These studies will be conducted with the racemic mixture and with the isolated enantiomers and the results of both studies will be compared. Our motivation for the continuity of this project lies in the fact that our studies with fenamiphos, myclobutanil and fipronil pesticides in project 2016/07597-0 have shown a great potential for inhibition, by these pesticides, on cytochrome P450 enzymes. In addition, there are several enantioselective studies that evaluate the toxicity, ecotoxicity and environmental impact of pesticide enantiomers, and although humans are in contact with these toxicants (either during work or through food intake) enzyme inhibition studies and prediction of drug interactions for the evaluation of risks exposure to these products have been performed very little using human models. In this context, analytical methods will be developed and validated for this purpose. (AU)
