A series of polymethyl-substituted piperidines linked to either a 6-methoxy-1,2,3,4-tetrahydronaphthalen-l-yl or a 6-methoxynaphthalen-1-yl moiety was generated with the aim of verifying a previously generated hypothesis: tetralin and naphthalene nuclei confer opposite activity at the sigma(1) receptor. Compounds 6, 9 and 10 displayed appreciable affinity at both sigma subtypes, but none of the novel compounds displayed significant antiproliferative activity in MCF7wt and MCF7 sigma 1 cell lines. The effect on bradikynin-triggered Ca2+ mobilization was studied as a methodology to suggest a receptors mediated activity. (C) 2013 Elsevier Ltd. All rights reserved.
