Might Adrenergic α2C-Agonists/α2A-Antagonists Become Novel Therapeutic Tools for Pain Treatment with Morphine?
摘要:
The imidazoline nucleus linked in position 2 via an oxyethylene bridge to a phenyl ring carrying an ortho substituent of moderate steric bulk provided alpha(2)-adrenergic (AR) ligands endowed with significant alpha(2C)-agonism/alpha(2A)-antagonism. Similar behavior was displayed by cirazoline (12). For their positive morphine analgesia modulation (due to alpha(2C)-AR stimulation) and sedation overcoming (due to alpha(2A)-AR antagonism), 8 and 11 might be useful as adjuvant agents in the management of pain with morphine.
