Three analogues of To042, a tocainide-related lead compound recently reported for the treatment of myotonia, were synthesized and evaluated in vitro as skeletal muscle sodium channel blockers possibly endowed with enhanced use-dependent behavior. Patch-clamp experiments on hNav1.4 expressed in HEK293 cells showed that N-[(naphthalen-1-yl)methyl]-4-[(2,6-dimethyl)phenoxy]butan-2-amine, the aryloxyalkyl bioisostere of To042, exerted a higher use-dependent block than To042 thus being able to preferentially block the channels in over-excited membranes while preserving healthy tissue function. It also showed the lowest active transport across BBB according to the results of P-glycoprotein (P-gp) interacting activity evaluation and the highest cytoprotective effect on HeLa cells. Quantum mechanical calculations and dockings gave insights on the most probable conformation of the aryloxyalkyl bioisostere of To042 in solution and the target residues involved in the binding, respectively. Both approaches indicated the conformations that might be adopted in both the unbound and bound state of the ligand. Overall, N-[(naphthalen-1-yl)methyl]-4-[(2,6-dimethyl)phenoxy]butan-2-amine exhibits an interesting toxico-pharmacological profile and deserves further investigation.

A novel series of triple reuptake inhibitors were explored by ligand-based drug design. A cyclic structure was designed from cyclopropane derivative 5 using the core structure of reported monoamine reuptake inhibitors, leading to the formation of the 1-aryl-1,4-diazepan-2-one derivative 23j-S. Compound 23j-S was shown to act as a potent TRI with an excellent ADME-Tox profile. Oral administration of 23j-S significantly enhanced norepinephrine, dopamine, and serotonin levels in the mouse prefrontal cortex and showed significant antidepressant-like activity in tail suspension tests in mouse.
