Abstract
Analytical HPLC methods using derivatized cellulose chiral stationary phases were developed for the direct enantioseparation of substituted [1-(imidazo-1-yl)-1-phenylmethyl)]-benzothiazolinone and benzoxazolinone derivatives with one chiral center. Those analogues of fadrozole constitute new potent nonsteroidal inhibitors of aromatase (P450 arom). The separations were made using normal phase methodology with a mobile phase consisting of n-hexane-alcohol (ethanol, 1-propanol, or 2-propanol) in various proportions, and a silica-based cellulose tris-3,5-dimethylphenylcarbamate (Chiralcel OD-H), or tris-methylbenzoate (Chiralcel OJ). The effects of concentration of various aliphatic alcohols in the mobile phase were studied. A better separation was achieved on cellulose carbamate phase compared with the cellulose ester phase. The effects of structural features of the solutes along with the temperature of the column on the discrimination between the enantiomers were examined. Baseline separation (Rs > 1.5) was easily obtained in many cases.

Abstract
Analytical HPLC methods using derivatized cellulose chiral stationary phases were developed for the direct separation of the stereoisomers of disubstituted tetralin derivatives with two chiral centers, new agonist and antagonist ligands for melatonin receptors.

Abstract
Analytical HPLC methods using derivatized cellulose chiral stationary phases were developed for the separation of the enantiomers of methoxy and ethyl tetrahydronaphthalenic derivatives, new agonist and antagonist ligands for melatonin receptors. The resolution were made using normal-phase methodology with a mobile phase consisting of n-hexane-alcohol (methanol, ethanol, 1-propanol or 2-propanol) in various percentage, and a silica-based cellulose tris-3,5-dimethyl-phenylcarbamate (Chiralcel OD-H), or tris-methylbenzoate (Chiralcel OJ). The mobile phase and the chiral stationary phase were varied to achieve the best resolution. The effects of concentration of alcohol, various aliphatic alcohols in the mobile phase were studied. The effects of substitution were analysed. Baseline separation (R(s) > 1.5) was easily obtained in many cases. The resolution results were complementary between the two columns.

Abstract
In order to obtain milligram amounts of the enantiomers of a series of compounds to be tested for binding to the melatonin binding site, a system for semipreparative enantiomeric separation was set up using tri-acetylcellulose as the chiral stationary phase. Interactions of this class of compounds with tri-acetylcellulose were examined on an analytical scale with a series of 20 compounds. Apparently, both steric and electrostatic interactions determine retention behavior on tri-acetylcellulose. Semipreparative separations were carried out for a subset of seven compounds. The purity of the first eluting enantiomer usually was around 99%, whereas the purity of the second eluting enantiomer was slightly less. The system described is easy to use and has the major advantage that a series of compounds can be separated with one technique. The purities obtained are sufficient for a first screen of their affinity.
