Disclosed is a composition and method for a therapeutic treatment that is able to combat certain conditions such as addiction, alcohol dependence, opioid abuse treatment, neurological disorders, neuropathic pain, and combinations thereof. The compounds act by acting as selective antagonist to the kappa (κ) opioid receptor, which, when present leads to the inhibition of conditions, providing increased performance over known treatments. The disclosed compounds also shows the ability to cross the blood-brain-barrier in a highly efficient manner. The disclosed compounds are shown to be effective in the nanomolar range.
