HY-119980

Fluphenazine	Antagonist	98.70%
Fluphenazine is a potent, orally active phenothiazine-based dopamine receptor antagonist. Fluphenazine blocks neuronal voltage-gated sodium channels. Fluphenazine acts primarily through antagonism of postsynaptic dopamine-2 receptors in mesolimbic, nigrostriatal, and tuberoinfundibular neural pathways. Fluphenazine can antagonize Methylphenidate-induced stereotyped gnawing and inhibit climbing behaviour in mice. Fluphenazine can be used for researching psychosis and painful peripheral neuropathy associated with diabetes and has potential to inhibit SARS-CoV-2.

HY-B1470

Azaperone	Antagonist	99.23%
Azaperone is an antagonist of dopamine D2 receptor (Dopamine D2 Receptor) and α-adrenergic receptor (AR). Azaperone reduces vasomotor tone, mean arterial pressure, hematocrit, hemoglobin concentration, and etorphine-induced duration; induces transient tachycardia followed by bradycardia, splenic uptake of red blood cells, and sedation; alters animal behaviors; and produces sedation with distinct onset and duration in foals. Azaperone is used for sedation and tranquilization in various animals to reduce stress and aggressive behaviors, and serves as a preanesthetic agent.
