Nalmefene

• Description :

  Nalmefene is a BBB-penetrable opioid receptor modulator. Nalmefene is an antagonist of MOR and DOR, and a partial agonist of KOR. Nalmefene has anti-inflammatory and neuroprotective activities. Nalmefene can be used in the research of reducing alcohol-dependent disorders[1][2][3][4].
