Modeling studies demonstrate that aryl piperazines (I), aryloxyalkylamines (II), phenylalkykamines (III) and indolylalkylamines (VI) may interact at 5-HT receptors in a similar manner. Examination of these structures (I-VI) reveals that all possess an aromatic moiety and terminal amine binding sites (Glennon et al., J Med Chem 32(8):1921-1926, 1989). In the present investigation a new series of aryloxyalkylamines (4, 5, 8, and 9) was designed and synthesized, in which the aromatic moiety is a phenyl group substituted at the 2,3-, 2,4-, 2,5-, or 2,6-positions by halogens and the terminal amine is N-methylpiperazine, or morpholine. In addition, the alkyl side chain is ethyl, or substituted ethyl at the α- or β-carbon by a methyl group. The length of the alkyl chain that separates the terminal amine from the ether oxygen atom of the aryloxy group is of major importance, and two-carbon chain appears optimal. The structures of the new compounds were assessed by microanalyses, IR, and NMR. The analgesic activity of selected compounds was performed on experimental animals and proved to be in the range of 85-100% relative to aspirin. Springer Science+Business Media, LLC 2011.

The invention relates to compounds of the formula: STR1 in which: Ar represents a phenyl group substituted by R2, R3 and R4, or a naphth-1-yl or naphth-2-yl group, unsubstituted or substituted by 1 or 2 halogen atoms; X represents an oxygen atom or a sulfur atom; R1 represents H or a halogen atom; R2 represents a halogen atom, a trifluoromethyl group, a phenyl group which is unsubstituted by 1 or 3 halogen atoms, a benzyl group which is unsubstituted or substituted by 1 to 3 halogen atoms, a phenoxy group which is unsubstituted or substituted by 1 to 3 halogen atoms, or a C1 -C4 alkyl group; R3 and R4 represents H, a halogen atom or a C1 -C4 alkyl group; and the benzyl group substitutes the piperidino radical in the 2-, 3- or 4-position, and their salts with mineral or organic acids. It also relates to a process for the preparation of said compounds and their use as antimicrobial agents, as antiseptic, disinfectant, preservative in different kinds of products (pharmaceutical compositions, cosmetics, agri-foodstuffs). It also relates to said products containing the compounds of formula (I).
