To obtain an insight into the interactions of potential anticonvulsant drugs
with their surrounding, two series of 5-methyl-5-aryl- and
5-ethyl-5-arylhydantoins were synthesized and their absorption spectra were
recorded in the region from 200 to 400 nm in a set of selected solvents. The
effects of solvent dipolarity/polarizability and solvent-solute hydrogen
bonding interactions on the absorption maxima shifts were analyzed by means
of the linear solvation energy relationship (LSER) concept of Kamlet and
Taft. The ratio of the contributions of specific and nonspecific
solvent-solute interactions were correlated with the corresponding ADME
properties of the studied compounds. The correlation equations were combined
with different physicochemical parameters to generate new equations, which
demonstrate the reasonable relationships between solvent-solute interactions
and the structure-activity parameters.
