In some cases, an inhibitor can bind to more than one site on an enzyme protein, with inhibition resulting from binding at multiple sites. Binding affinities at the two (or more) sites may be different, and mechanisms of inhibition may be dilferent for example, high-affinity inhibition might occur through an allosteric site and lower affinity inhibition through the active site. Analysis of such systems is complex and may require a combination of several of the approaches outlined later. [Pg.114]

As the computational methods used in pharmaceutical development have improved, receptor binding analysis has led to many potential new drug candidates that are polycyclic. Such leads are often not pursued, however, because of the perception that even if it turned out to be active, an enantiomerically-pure polycyclic agent would be too expensive to manufacture. Taking this as a challenge, academic research groups continue to develop clever approaches for the efficient synthesis of complex polycarbocyclic target structures. Three recent approaches are outlined here. [Pg.23]

A simple example of a frontal analysis system is one where an applied analyte binds to a single type of immobilized ligand site. In this situation, the following equation can be used to relate the true number of active binding sites in the column (m ) to the apparent moles of analyte (m app) required to reach the mean position of the breakthrough curve ... [Pg.225]

The activation of DNT has been shown to be a multistep process involving metabolism in the liver, excretion into the bile, deconjugation of metabolites and further metabolism by the intestinal flora, re-uptake (enterohepatic transport) of metabolites into liver, and finally activation and binding to cellular macromolecules in the liver [56], More recent studies [57] involving rats pretreated with coal tar creosote, which potentiates the genotoxicity of 2,6-DNT, elucidated a complex interaction that balances metabolic activation, uptake, and detoxification. The study monitored intestinal flora enzyme activities, bacterial analysis, mutagenicity of urine samples, HPLC analysis, and hepatic DNA adducts over a five-week exposure period. The location of nitroreductase activity was an... [Pg.189]
