HY-B0678S

Metaxalone-d3

Metaxalone-d₃ is the deuterium labeled Metaxalone. Metaxalone (AHR438; NSC170959) is an FDA-approved muscle relaxant. Metaxalone acts mainly on the central nervous system and achieves muscle relaxation by inhibiting polysynaptic reflex arcs. In addition, Metaxalone is an inhibitor of MAO-A, which has anti-inflammatory and antioxidant effects. Metaxalone inhibits IL-1β-induced inflammatory phenotype, modulates NF-κB and other related signaling pathways, and decreases MAO-A expression and activity in IL-1β-treated microglia .

Metaxalone-d₆ is deuterium labeled Metaxalone. Metaxalone (AHR438; NSC170959) is an FDA-approved muscle relaxant. Metaxalone acts mainly on the central nervous system and achieves muscle relaxation by inhibiting polysynaptic reflex arcs. In addition, Metaxalone is an inhibitor of MAO-A, which has anti-inflammatory and antioxidant effects. Metaxalone inhibits IL-1β-induced inflammatory phenotype, modulates NF-κB and other related signaling pathways, and decreases MAO-A expression and activity in IL-1β-treated microglia .

HY-B1833S

Afloqualone-d7
Afloqualone-d₇ (HQ-495-d₇) is deuterium labeled Afloqualone. Afloqualone (HQ-495) is an orally active central muscle relaxant and antivertiginous agent that can increase the sensitivity of GABA receptors in neurons of the lateral vestibular nucleus. Afloqualone (HQ-495) can be used in the research of low back pain and neck-arm-shoulder syndrome .

HY-B0194AS

Tizanidine-d4 hydrochloride

Tizanidine-d₄ hydrochloride is deuterium labeled Tizanidine hydrochloride (HY-B0194A). Tizanidine hydrochloride, a skeletal muscle relaxant, is an orally effective central α₂-adrenoceptor agonist (IC₅₀ = 6.9 nmol). Tizanidine hydrochloride primarily exerts muscle relaxation effects by inhibiting the release of excitatory amino acids (glutamate and aspartate) from the presynaptic terminals of spinal cord interneurons. Tizanidine hydrochloride has anti-injury activity and can inhibit gastrointestinal (GI) transport. Tizanidine hydrochloride can inhibit the proliferation, migration, and invasion of lung cancer cells and induce cell apoptosis by upregulating Nischarin and inhibiting the AKT and Wnt3a/β-catenin signaling pathways. Tizanidine hydrochloride can be used to treat spasticity caused by diseases such as multiple sclerosis (MS), stroke, and spinal cord injury (SCI).

HY-W016221S

6-Hydroxy Chlorzoxazone-d2
6-Hydroxy Chlorzoxazone-d₂ is deuterium labeled 6-Hydroxy Chlorzoxazone. 6-Hydroxy Chlorzoxazone is a metabolite of Chlorzoxazone (HY-B1462). Chlorzoxazone is a centrally acting muscle relaxant used to treat muscle spasm and the resulting pain or discomfort .

HY-B1139S

Tolperisone-d10 hydrochloride

Tolperisone-d₁₀ (hydrochloride) is the deuterium labeled Tolperisone hydrochloride. Tolperisone hydrochloride is a centrally acting muscle relaxant, is indicated for use in the treatment of pathologically increased tone of the cross-striated muscle caused by neurological diseases (damage of the pyramidal tract, multiple sclerosis, myelopathy, encephalomyelitis) and of spastic paralysis and other encephalopathies manifested with muscular dystonia.

HY-W709349S

Flupirtine-d6 hydrochloride

Flupirtine-d₆ (D 9998-d₆) hydrochloride is the deuterium labeled Flupirtine hydrochloride (HY-W709349). Flupirtine hydrochloride is an orally active, blood-brain barrier-crossing non-opioid analgesic and neuroprotective agent. Flupirtine hydrochloride is a neuronal potassium channel opener (Kv7 activator), a NMDA receptor antagonist and a GABA receptor activator. Flupirtine hydrochloride stabilizes blood-brain-barrier integrity, reduces oxidative stress and brain leukocyte infiltration, enhances angioneurogenesis, suppresses calcium influx, stabilizes neuronal resting membrane potential, and counteracts focal cerebral ischemia. Flupirtine hydrochloride exhibits analgesic, muscle relaxant properties, protects neurons from excitotoxic, ischemic, or cytokine-mediated death. Flupirtine hydrochloride functions as a non-opioid analgesic without antipyretic or antiphlogistic properties, shows no relevant affinity to opiate receptor. Flupirtine hydrochloride can be used for the research of focal cerebral ischemia, pain, Alzheimer’s disease, or multiple sclerosis .
