Samidorphan-d₄  (Synonyms: ALKS-33-d₄; RDC-0313-d₄)

Samidorphan-d4 is the deuterium labeled Samidorphan(HY-123689).Samidorphan (ALKS-33) is an orally active opioid system modulator that has a high affinity for binding with μ‐opioid, κ‐opioid, and δ‐opioid receptors. Samidorphan acts as an antagonist at μ‐opioid receptors and acts as a partial agonist at k-opioid and δ‐opioid receptors. Samidorphan primarily acts as an opioid receptor antagonist in vivo^[1].
