    • Bio Activity:

      6-Alpha Naloxol(Alpha-Naloxol) is an opioid antagonist closely related to naloxone; a human metabolite of naloxone.; IC50 value:; Target: opioid antagonist; When responding over the entire 30 min operant session was examined, naloxone was only 5-fold more potent than 6-alpha-naloxol in suppressing operant responding under Morphine Na?ve conditions, but this increased to a 65-fold potency difference after Single or Repeat Morphine pretreatment.
