In this study both the PCILO and empirical energy methods were used to characterize intermolecular interactions of typical N-substituents of rigid opiates with model anionic receptor sites. Ammonium methylphosphate (AMP) and ammonium methylsulfate (AMS) were used as model anionic receptor sites. Interaction energies of eight compounds which, as N-substituents. modulate different antagonist/agonist potencies...

Figure 4.3 shows a schematic diagram of the system for orthosteric antagonism. Two temporal extremes will be considered first. Complete competitive equilibrium can be achieved when there is sufficient time for the antagonist, agonist, and receptors to come to correct equilibrium when agonist response...
