Herein is described a new class of selective σ1 ligands consisting of tetrahydroisoquinoline-hydantoin (Tic-hydantoin) derivatives. Compound 1a has high affinity (IC50 = 16 nM) for σ1 receptor and is selective in a large panel of therapeutic targets. This study presents structural changes on the side chain of the Tic-hydantoin core. Analogs of higher affinity could be identified (IC50 ≈ 2-3 nM).
N-[(amino)alkyl]-1-pyrrolidine, 1-piperidine and 1-homopiperidinecarboxamides (and thiocarboxamides) with sulfur linked substitution in the 2, 3 or 4-position

Novel pyrrolidine, piperidine and homopiperidinecarboxamide and thiocarboxamide compounds having the formula: STR1 wherein X is --S--, --S(O)-- or --S(O)2 --; A is a loweralkalene chain and A1 and A2 are alkalene chains when p and d are one; R, R1 and R2 are hydrogen, loweralkyl, phenyl cycloalkyl or phenylalkyl and R1 and R2 may form a heterocyclic residue with the adjacent nitrogen atom; Q is a selected aromatic radical, and the pharmaceutically acceptable acid addition salts useful as cardiac antiarrhythmia agents are disclosed. Novel chemical intermediates, unsubstituted on pyrrolidine, piperidine and homopiperidine nitrogen but with --(A2)p --X--(A2)d --Q side chain are also disclosed.
