D₃ Receptor Inhibitor

CYD-1-79 is a selective positive allosteric modulator of 5-HT2C receptor. CYD-1-79 potentiates 5-HT-evoked intracellular calcium release via a topographically distinct allosteric site. CYD-1-79 shows significant inhibition of binding at dopamine D3 receptor, DAT, and α2A/α2B adrenergic receptors. CYD-1-79 modulates 5-HT2C receptor-mediated spontaneous ambulation in rodents and synergizes with a low dose of a 5-HT2C receptor agonist. CYD-1-79 attenuates relapse vulnerability of psychoactive substance in a rodent self-administration model. CYD-1-79 can be used for the research of neurological disease.

Tiapride hydrochloride is a selective and orally active D₂ and D₃ dopamine receptors antagonist with IC₅₀ values of 110-320 nM and 180 nM, respectively. Tiapride hydrochloride shows anti-dyskinetic activity and anxiolytic activity. Tiapride hydrochloride is a neuroleptic agent.

Benzquinamide (P2647; BZQ; Benzoquinamide) hydrochloride is an orally active binder of dopamine receptors and adrenergic receptors. Benzquinamide hydrochloride specifically targets dopamine D2, D3, D4 receptors and α-2A, α-2B, α-2C adrenergic receptors. Benzquinamide hydrochloride regulates blood pressure and heart rate, attenuates the pressor effect of adrenaline, and exhibits activities such as antiemesis, anxiolysis, and reduction of histamine-induced bronchoconstriction. Benzquinamide hydrochloride has good safety and does not deplete serotonin or norepinephrine in the brain. Benzquinamide hydrochloride can be used in studies related to nausea/vomiting, mental disorders, anxiety states, neurosis, and psychosis.

Clomipramine-d₃ (hydrochloride) is a deuterium labeled Clomipramine hydrochloride. Clomipramine hydrochloride is a serotonin transporter (SERT), norepinephrine transporter (NET) dopamine transporter (DAT) blocker with K_i of 0.14, 54 and 3 nM, respectively.

Nomifensine-d₃ ((±)-Nomifensine-d₃) maleate is the deuterium labeled Nomifensine maleate (HY-B1110A). Nomifensine ((±)-Nomifensine) maleate is a potent norepinephrine (NE) and dopamine (DA) reuptake inhibitor. Nomifensine maleate inhibits uptake of NE, DA and 5-HT in rat brain synaptosomes, with IC₅₀ values of 6.6 nM, 48 nM and 830 nM, and K_i values of 4.7 nM, 26 nM and 4000 nM, respectively. Nomifensine maleate has antidepressant and analgesic effects. Nomifensine maleate is used in neurodegenerative diseases, compound addiction, and pain research.

Clomipramine-d₃ is the deuterium labeled Clomipramine. Clomipramine is a serotonin transporter (SERT), norepinephrine transporter (NET) dopamine transporter (DAT) blocker with K_i of 0.14, 54 and 3 nM, respectively.

Benztropine-¹³C,d₃ (mesylate) is the ¹³C- and deuterium labeled Benztropine (mesylate). Benztropine mesylate (Benzatropine mesylate) is an orally active centrally acting anticholinergic agent that can be used for Parkinson's disease research. Benztropine mesylate is an anti-histamine agent and a dopamine re-uptake inhibitor. Benztropine mesylate is also a human D2 dopamine receptor allosteric antagonist. Benztropine mesylate also has anti-CSCs (cancer stem cells) effects.

SUN-1334H free base is an orally active inhibitor for histamine H1 receptor, with an IC₅₀ of 20.3 nM and K_i of 9.7 nM. SUN-1334H free base inhibits histamine-induced contractions of isolated guinea-pig ileum with an IC₅₀ of 0.198 μM. SUN-1334H free base inhibits histamine-induced bronchoconstriction in guinea pigs, histamine-induced skin wheals in beagle dogs, and ovalbumin-induced rhinitis in guinea pigs.

Benzquinamide (P2647; BZQ; Benzoquinamide) is an orally active binder of dopamine receptors and adrenergic receptors.

Benzquinamide regulates blood pressure and heart rate, attenuates the pressor effect of adrenaline, and exhibits activities such as antiemesis, anxiolysis, and reduction of histamine-induced bronchoconstriction. Benzquinamide has good safety and does not deplete serotonin or norepinephrine in the brain. Benzquinamide can be used in studies related to nausea/vomiting, mental disorders, anxiety states, neurosis, and psychosis.
