摘要: Peripheral selective μ opioid receptor (MOR) antagonists could alleviate the symptoms of opioid-induced constipation (OIC) without compromising analgesic effect opioids. However, a variety adverse effects were associated with them, partially due to their relatively low MOR selectivity. NAP, 6β-N-4′-pyridyl substituted naltrexamine derivative, was identified previously as potent and highly antagonist mainly acting within peripheral nervous system. The noticeable diarrhea it prompted design synthesis its analogues in order study structure–activity relationship. Among compound 8 showed improved pharmacological profiles compared original lead, at while increasing intestinal motility morphine-pelleted mice (ED50 = 0.03 mg/kg). slight decrease ED50 lead well compensated by unobserved effect. Hence, this seems be more promising de...
