In vitro bioassays were used to analyze the metabolism of the 11-dodecenoic acid (11-DDNA) by microsomes prepared from Drosophila melanogaster RalDDTR strain. 11-DDNA is metabolized to 11,12-epoxylauric acid (epoxyLA) in a NADPH-dependent way. The microsomal production of epoxyLA reaches a plateau very quickly, suggesting the occurrence of an enzyme inactivation process. After incubation of microsomes with (1-14C)11-DDNA, three proteins of Mr approximately 50 kDa were labeled. 11-DDNA inhibits the microsomal metabolism of lauric acid and 7-ethoxycoumarin in a time and NADPH-dependent process. An inhibition of metabolites generated from DDT and testosterone was also obtained but at higher concentrations. These results are discussed according to the fact that RalDDTR is an insecticide resistant strain characterized as a high metabolizer of the insecticide DDT and also of lauric acid, testosterone, and ethoxycoumarin. |
