1 P450 enzymes metabolize chlorpyrifos to chlorpyrifos-oxon, which is then metabolized primarily to 3, 5, 6-trichloropyridinol in addition to diethylphosphate and diethylthiophosphate. Chlorpyrifos cytochrome P450 family 2 subfamily B member 6 Homo sapiens
2 The P450 inhibitor SKF525A partly negated the protective effect of astrocytes, allowing reduction in branch points with chlorpyrifos (10 muM). Chlorpyrifos cytochrome P450 family 2 subfamily B member 6 Homo sapiens
3 Thus, the scalable and defined astrocyte-neuron cocultures model that we established here has potentially identified a role for P450 enzymes in astrocytic neuroprotection against chlorpyrifos and provides a novel model for addressing DNT in a more accurate multicellular environment. Chlorpyrifos cytochrome P450 family 2 subfamily B member 6 Homo sapiens
