The blood brain barrier (BBB) VolSurf model was used to predict the BBB permeation profiles of our synthesized compounds. Some compounds show both remarkable analgesic activity and good BBB permeation profiles, and these compounds might be developed for treatment of opioid tolerance and dependence. %K Agmatine derivatives %K synthesis %K analgesic activity %K blood-brain barrier %K opioid dependence. %U http://www.mdpi.com/1420-3049/11/6/393
