Naratriptan-d3

Naratriptan-d₃ (GR-85548A-d₃) is the deuterium labeled Naratriptan (HY-B0197). Naratriptan is a selective 5-HT1B/1D receptor agonist. Naratriptan is peripherally active and has good oral bioavailability, inducing cranial artery vasoconstriction by activating 5-HT1B/1D receptors (EC₅₀=0.11 μM for dog basilar artery). Naratriptan also inhibits trigeminal nerve-mediated dural neurogenic plasma extravasation and reduces sterile inflammation. Naratriptan is mainly used in the research of acute migraine, targeting cranial vascular and neuroinflammatory mechanisms .

HY-B0383AS

Almotriptan hydrochloride-d6

Almotriptan-d₆ (PNU180638-d₆) hydrochloride is the deuterium labeled Almotriptan hydrochloride. Almotriptan hydrochloride is an orally active, highly selective agonist of the 5-HT_1B/1D receptor (5-HT_1B/1D receptor), with EC₅₀ values of 1.6 nM and 3.1 nM, respectively. Almotriptan hydrochloride shows moderate affinity for the 5-HT1F receptor, and weak affinity for the 5-HT1A, 5-HT6 and 5-HT7 receptors. Almotriptan hydrochloride induces intracranial vasoconstriction, inhibits nociceptive neurotransmission in the trigeminocervical complex, and suppresses the release of vasoactive peptides from trigeminal nerve endings. Almotriptan hydrochloride can be used in research related to migraine.

HY-B0383AS2

Almotriptan-d3 benzoate

Almotriptan-d₃ benzoate (PNU180638 free base-d₃) is deuterated labeled Almotriptan benzoate. Almotriptan benzoate is an orally active, highly selective agonist of the 5-HT_1B/1D receptor (5-HT_1B/1D receptor), with EC₅₀ values of 1.6 nM and 3.1 nM, respectively. Almotriptan benzoate shows moderate affinity for the 5-HT1F receptor, and weak affinity for the 5-HT1A, 5-HT6 and 5-HT7 receptors. Almotriptan benzoate induces intracranial vasoconstriction, inhibits nociceptive neurotransmission in the trigeminocervical complex, and suppresses the release of vasoactive peptides from trigeminal nerve endings. Almotriptan benzoate can be used in research related to migraine.
