Diaziquone, 2,5-diaziridinyl-3,6-biscarboethoxyamino-1,4-benzoquinone, plasma and cerebrospinal fluid kinetics.
Plasma and cerebrospinal fluid (CSF) kinetics of diaziquone, 2,5-diaziridinyl-3,6-biscarboethoxyamino-1,4-benzoquinone (AZQ), were evaluated after intravenous injection in patients with implanted Ommaya reservoirs. After a 30-min infusion plasma disappearance was very rapid, with a disposition half-life of 2 to 6 min and on elimination half-life of 25 to 35 min. Area under the concentration-time curve for CSF was 22% to 42% of the corresponding plasma area. Based upon total plasma AZQ concentration, volume of distribution for AZQ was 2.0 to 10.0 l/m2. Plasma binding of AZQ was 79% in one normal subject. When the effect of plasma binding is considered, distribution volumes are more plausible and it appears that free plasma AZQ is completely available to the CSF.
