HY-123689S

Samidorphan-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 .

HY-123689S1

Samidorphan-d5

Samidorphan-d5 (ALKS-33-d5) is is a deuterated compound of Samidorphan. Samidorphan is an orally active opioid system modulator that binds with high affinity to μ-opioid, κ-opioid, and δ-opioid receptors. Samidorphan is a μ-opioid receptor antagonist and a partial agonist at k-opioid and δ-opioid receptors. Samidorphan acts primarily as an opioid receptor antagonist in vivo .

HY-A0118AS

Naloxegol-d5 oxalate
Naloxegol-d₅ (oxalate) is deuterium labeled Naloxegol (oxalate). Naloxegol oxalate (NKTR-118 oxalate; AZ-13337019 oxalate) is a μ-opioid-receptor antagonist. Naloxegol oxalate inhibits opioid binding in μ-opioid receptors in the gastrointestinal tract and effective for alleviating opioid-induced constipation[1][2].

HY-109054AS

O-Desmethyltramadol-d6 hydrochloride
O-Desmethyltramadol-d6 (hydrochloride) is a deuterated labeled O-Desmethyltramadol (hydrochloride) . O-Desmethyltramadol (hydrochloride) is a primary active metabolite of Tramadol. O-Demethyltramadol is mainly responsible for its μ-opioid receptor-related analgesic effect. Tramadol is metabolized to O-Demethyltramadol mainly by the cytochrome P450 (CYP) 2D6 enzyme .
