- 1 September 2001
One of the factors determining the toxicity of chlorpyrifos (CPS), an organophosphorus (OP) insecticide, is its biotransformation. CPS can be activated by cytochrome P450 (CYP) through a… Expand
Identification of variants of CYP3A4 and characterization of their abilities to metabolize testosterone and chlorpyrifos.

- 1 December 2001
CYP3A4 is the most abundant isoform of cytochrome P450 (CYP) in adult human liver. It metabolizes numerous clinically, physiologically, and toxicologically important compounds. The expression of… Expand
Insect Cytochrome P450
- E. Hodgson, R. Rose
- Biology
- 1991
Cytochrome P450 (P450) dependent monooxygenase systems occur in most if not all organisms, from bacteria to mammals and higher plants. In insects, the biochemical functions ascribed to this enzyme… Expand
In vitro metabolism of carbaryl by human cytochrome P450 and its inhibition by chlorpyrifos.
- J. Tang, Y. Cao, R. Rose, E. Hodgson
