A small library of fluoroethoxy-1,4-diphenethyl piperidine and fluoroethoxy-1,4-diphenethyl piperazine derivatives were designed, synthesized and evaluated for their ability to inhibit [3H]dopamine (DA) uptake at the vesicular monoamine transporter-2 (VMAT2) and dopamine transporter (DAT), [3H]serotonin (5-HT) uptake at the serotonin transporter (SERT), and [3H]dofetilide binding at the human-ether-a-go-go-related gene (hERG) channel. The majority of the compounds exhibited potent inhibition of [3H]DA uptake at VMAT2, Ki changes in the nanomolar range (Ki = 0.014–0.073 μM). Compound 15d exhibited the highest affinity (Ki = 0.014 μM) at VMAT2, and had 160-, 5-, and 60-fold greater selectivity for VMAT2 vs. DAT, SERT and hERG, respectively. Compound 15b exhibited the greatest selectivity (>60-fold) for VMAT2 relative to all the other targets evaluated, and 15b had high affinity for VMAT2 (Ki = 0.073 μM). Compound 15b was considered the lead compound from this analog series due to its high affinity and selectivity for VMAT2.

A series of lobelane analogues has been synthesized and their structure-activity relationships at the vesicular monoamine transporter-2 (VMAT2) have been evaluated. The most potent analogues in this series were the cis-2,6-piperidino analogues, 25b, 27b, 28b, and 30b, with Ki values ranging from 430 to 580 nM.
