The identification of specific nuclear receptors as molecular targets of P450 inducers impacts diug metabolism and diug development in several important ways ... 

Here Z is the charge of the projectile with velocity v. In order to calculate stopping powers for atomic and molecular targets with reliability, however, one must choose a one-electron basis set appropriate for calculation of the generalized oscillator strength distribution (GOSD). The development of reasonable criteria for the choice of a reliable basis for such calculations is the concern of this paper. 

While the main focus of this chapter has been on enzymes as the primary molecular targets of drug action, it is worthwhile noting that the quantitative evaluation of enzyme activity has other important roles in drug discovery and development. 

A multitude of semiempirical and semiclassical theories have been developed to calculate electron impact ionization cross sections of atoms and atomic ions, with relatively few for the more complicated case of molecular electron impact ionization cross sections. One of the earlier treatments of molecular targets was that of Jain and Khare.38 Two of the more successful recent approaches are the method proposed by Deutsch and Mark and coworkers12-14 and the binary-encounter Bethe method developed by Kim and Rudd.15,16 The observation of a strong correlation between the maximum in the ionization efficiency curve and the polarizability of the target resulted in the semiempirical polarizability model which depends only on the polarizability, ionization potential, and maximum electron impact ionization cross section of the target molecule.39,40 These and other methods will be considered in detail below. 

Many of the novel pharmacotherapeutic agents currently under development are directed toward a single molecular target related to cocaine or known to be regulated by cocaine. Although this... 

Development and validation of PD assays to confirm drug effect on molecular target in pre-clinical studies and clinical trials conducted under an exploratory INDA, or in a traditional Phase I/II setting... 

For testing the biological activity of such a large number of molecules, development of fast assays and with a read-out as simple as possible is essential. These assays can be performed on molecular targets (biochemical assays) or target cell (cell-based assays).
