Mebhydrolin napadisylate (Incidal) is an antihistamine used to relieve allergic symptoms caused by histamine release, including nasal allergies and allergic dermatosis.

Mirtazapine (6-Azamianserin) is a tetracyclic antidepressant with a somewhat unique mechanism of action. Mirtazapine therapy can be associated with transient asymptomatic elevations in serum aminotransferase levels and has been linked to rare instances of clinically apparent acute liver injury.

Brompheniramine maleate (Dimotane) is an antagonist against histamine H1 receptors.

Levodropropizine ((S)-(-)-Dropropizine) is a histamine receptor inhibitor. It is used as an effective and very well tolerated peripheral antitussive drug.

Pheniramine maleate (Trimetose), an alkylamine derivative with antihistaminic and vasodilatory properties, binds to histamine H1 receptors, thereby inhibiting phospholipase A2 and production of the endothelium-derived relaxing factor, nitric oxide.

Cloperastine hydrochloride (HT-11 hydrochloride) is a type of flavonoid.

Mianserin hydrochloride (Org GB 94) is a tetracyclic compound with antidepressant properties that blocks alpha-adrenergic, histamine H1, and certain serotonin receptors; it may cause drowsiness and hematological issues.

Histamine (Ergamine) is an amine derived by the enzymatic decarboxylation of histamine. Histamine is a potent stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and a neurotransmitter of central action.

Olopatadine hydrochloride (ALO4943A) is an antihistamine with mast-cell stabilizing properties used as eye drops in the treatment of ALLERGIC CONJUNCTIVITIS.

Doxepin hydrochloride (Aponal) is a dibenzoxepin tricyclic compound. It displays a range of pharmacological actions including maintaining adrenergic innervation. Its mechanism of action is not fully understood, but it appears to block reuptake of monoaminergic neurotransmitters into presynaptic terminals. It also possesses anticholinergic activity and modulates antagonism of histamine H(1)- and H(2)-receptors.

Olanzapine (LY170053) is an atypical antipsychotic that is used currently in the treatment of schizophrenia and bipolar illness.

Hesperetin belongs to the flavanone class of flavonoids. Hesperetin, in the form of its glycoside hesperidin, is the predominant flavonoid in lemons and oranges.

Quetiapine hemifumarate (ICI-204636), an atypical antipsychotic, is used in the treatment of bipolar I mania, schizophrenia, bipolar II depression, bipolar I depression.

Buclizine dihydrochloride (Buclina) is the hydrochloride salt form of buclizine, a piperazine histamine H1 receptor antagonist with primarily antiemetic and antivertigo activities. Buclizine dihydrochloride binds to and blocks the histamine H1 receptor, thereby preventing the symptoms that are caused by histamine activity. Buclizine dihydrochloride exerts its anti-emetic effect by binding to and blocking the muscarinic and histamine receptors in the vomiting center of the central nervous system (CNS). This may prevent activation of the chemoreceptor trigger zone (CTZ) and may reduce nausea and vomiting.

Epinastine hydrochloride (WAL-801CL HCl) is an antihistamine and mast cell stabilizer that is used in eye drops to treat allergic conjunctivitis.

Cyproheptadine hydrochloride is an effective orally active 5-HT2A receptor antagonist with antidepressant, anti-serotonin, and antiplatelet activities. It can be used for research on thromboembolic diseases and for the establishment of diabetes models.

Lafutidine (FRG-8813) is a newly developed histamine H2-receptor antagonist that inhibits gastric acid secretion.

Azatadine dimaleate (SCH10649) is an inhibitor for histamine（IC50=6.5 nM） and cholinergic（IC50=10 nM）.

Terfenadine ((±)-Terfenadine) is a prodrug metabolized by intestinal CYP3A4 into fexofenadine, an active selective histamine H1-receptor antagonist that possesses antihistaminic and non-sedative effects.

HT-0712 is a phosphodiesterase 4 (PDE4) inhibitor.

2-Methyl-5-HT (2-Methyl-5-hydroxytryptamine) is a potent, selective 5-HT3 receptor agonist exhibiting anti-depressive-like effects.

2-Methyl-5-HT maleate (2-Methyl-5-hydroxytryptamine maleate) is a potent and selective 5-HT3 receptor agonist with demonstrated anti-depressive-like effects[1].

2-Methyl-5-HT hydrochloride (2-Methyl-5-hydroxytryptamine) is a potent and selective 5-HT3 receptor agonist, exhibiting anti-depressive-like effects.

D3 5-HT receptor modulator-1 (compound 5i) is a selective antagonist of the dopamine D3 and 5-HT2A receptors, and a partial agonist at the 5-HT1A receptor. It exhibits Ki values of 4.5 nM, 11.9 nM, and 15.3 nM for the dopamine D3, 5-HT2A, and 5-HT1A receptors respectively. The compound shows lower affinity for the dopamine D2 receptor, 5-HT2C receptor, and hERG channel. D3 5-HT receptor modulator-1 possesses atypical antipsychotic properties.
