Webb5 okt. 2015 · Ticlopidine, a CYP2B6 substrate, prevented the enzyme from the inactivation induced by PRN. Exogenous nucleophile glutathione (GSH) and catalase/superoxide dismutase showed limited protection of CYP2B6 from the inactivation. The estimated partition ratio of the inactivation was approximately 400. WebbTiclopidine was potent with K(I) and k(inact) values of 0.32 microM and 0.43/min, respectively. The selectivity of these four agents for CYP2B6 was determined by testing their effects on other human P450 enzyme activities using conditions that yield approximately 90% inactivation of CYP2B6 activity.
