Research is devoted to creation of new bivalent opioid ligands (agonists and antagonists) for the treatment of pain (mainly neuropathic pain), and for multiple possible implementations of antagonists (management of opioid, cocaine, alcohol and nicotine addiction, treatment of dyskinesia on Parkinson's disease, targeting opioid-, adrenergic-, cannabinoid-, dopamine-, serotonin-, GABA-, glutamate- and other receptors). Design of these compunds is focused on creation of multiple bifunctional piperidine derivatives and their transformations to bivalent opioid ligands.
