A series of para-substituted 4-phenylpiperidines/piperazines have been synthesized and their affinity to recombinant rat cerebral cortex monoamine oxidases A (MAO A) and B (MAO B) determined. Para-substituents with low dipole moment increased the affinity to MAO A, whereas groups with high dipole moment yielded compounds with no or weak affinity. In contrast, the properties affecting MAO B affinity were the polarity and bulk of the para-substituent, with large hydrophobic substituents producing compounds with high MAO B affinity. In addition, these compounds were tested in freely moving rats and the effect on the post-mortem neurochemistry was measured. A linear correlation was demonstrated between the affinity for MAO A, but not MAO B, and the levels of 3,4-dihydroxyphenylacetic acid (DOPAC) and 3-methoxytyramine (3-MT) in the striatum.

Several homologous series of the 1,4-disubstituted piperazines of the general formulas 4a-l, 6a-k, 7a, b, 8a-r were synthesized.Most of the new substances are liquid crystalline.Besides nematic phases also smectic phases of the types A, B and E exist, which was proved by texture and miscibility studies.
