The aim of this study was to explore the mechanisms governing the intra- to extracellular unbound concentration ratio (Kpu,u) for the HIV protease inhibitor atazanavir (ATV) in rat hepatocytes. We had previously proposed a new method to determine Kpu,u by using the unbound Km values from metabolism studies with suspended rat hepatocytes and rat liver microsomes. Following that method, we determined that the value of ATV Kpu,u was 0.32, indicating that ATV hepatocellular clearance is uptake rate-limited. This hypothesis was supported by the linear correlation between Kpu,u and active uptake clearance (P = 0.04; R2=0.82) in the presence of increasing concentrations of the uptake transport inhibitor losartan. Moreover, in contrast to an expected increase of Kpu,u upon inhibition of ATV metabolism, a decrease of Kpu,u was observed, suggesting an increased impact of sinusoidal efflux. In summary, involvement of active uptake transport does not guarantee high intracellular accumulation; however, it has a key role in regulating intracellular drug concentrations and drug metabolism These findings will help improve future in vitro-to-in vivo extrapolations and likewise physiol. based pharmacokinetic models. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Application of 1614-12-6).
1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6) belongs to triazole derivatives. The many free lone pairs in triazoles make them useful as coordination compounds, although not typically as haptic ligands. Triazole growth retardants such as uniconazole and paclobutrazol have been known to inhibit the biosynthesis of gibberellins by blocking kaurene oxidase, an P450 enzymeApplication of 1614-12-6
