Description
| - Substances K-48 and HI-6, oxime-type acetylcholinesterase (AChE) reactivators, were tested for their potential to inhibit the activities of human liver microsomal cytochromes P450 (CYP). The compounds were shown to bind to microsomal cytochromes P450 with spectral binding constants of 0.25 ? 0.05 μM (K-48) and 0.54 ? 0.15 μM (HI-6). To find which cytochrome P450 from the human liver microsomal fraction interacts with these compounds, an inhibition of enzyme activities specific for nine individual CYP enzymes (CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4) was studied. The results have shown no prominent inhibition of individual CYP activities with both compounds except the CYP2E1 activity and the HI-6 reactivator. However, the inhibition of this activity was less than 50% which makes the possible drug interactions highly unlikely. Hence, the interaction of K-48 and HI-6 oxime-type AChE reactivators with human liver microsomal CYP enzymes does not seem to be clin
