A new series of benzhydryloxyalkylpiperazines carrying a trivalent function has been synthesized and studied for its effects on the central nervous system. Most of the compounds exhibit unexpected nonamphetaminic psychoanaleptic properties. The structure-activity studies revealed the importance of the nature and the position of the substituents on the phenyl rings. However, no significant correlation

According to the invention, there are provided novel amide derivatives and 5-lipoxygenase inhibitors containing the same as an effective ingredient. The above-mentioned compounds of the invention have been demonstrated to posses 5-lipoxygenase-inhibiting activities. These compounds can inhibit the production of leucotrienes such as LTC.sub.4 and LTD.sub.4 which are allergy-inducing factors by inhibiting the activity of 5-lipoxygenase. Accordingly, the amide derivatives can be used as 5-lipoxygenase inhibitors effective for allergic asthma, allergic rhinitis and the like.

GABA uptake inhibitors. Syntheses and structure—activity studies on GABA analogues containing diarylbutenyl and diarylmethoxyalkyl N-substituents

A number of analogues of GABA or B-alanine containing 4,4-diphenyl-3-butenyl (DPB), benzhydryl ethyl ether (BEE), or benzhydryl propyl ether N-substituents have been synthesized and tested as inhibitors of synaptosomal GABA uptake. N-methylation of these analogues resulted in increased potency and reduced pKa II values of the reaction products 4a and 8a, respectively. Incorporation of the alkyl groups of the benzhydryl alkyl ether moieties of N-methyl-N-BEE-B-alanine (12), N-methyl-N-BEE-GABA (8a), or the benzhydryl propyl ether analogue of N-methyl-GABA (10) into the cyclized piperidine analogues gave the less active compounds 17, 18, and 19, respectively. This loss of in vitro activity was most pronounced for the GABA analogues 18 and 19. These results suggest that the basic character of the amino groups as well as the conformational flexibility of the spacer-arm connecting the amino acid 'heads' and the aromatic moieties of this class of GABA uptake inhibitors are factors of importance for GABA uptake affinity.
