Taxifolin (Dihydroquercetin) is a flavonoid in many plants such as Taxus chinensis, Siberian larch, Cedrus deodara and so on.

Conopeptide rho-TIA, a peptide from Conus tulipa venom, acts as a selective, noncompetitive inhibitor at the human α1B-Adrenergic Receptor and as a competitive inhibitor at the α1A and α1D-Adrenergic Receptors. Binding to these subtypes, conopeptide rho-TIA may inform the creation of new α1-Adrenergic Receptor subtype-selective drugs [1].

Xamoterol hemifumarate is a potent and selective β1-adrenoceptor agonist.Xamoterol hemifumarate is a potential compound for the study of the relationship between cardiac arrhythmias and β1-adrenergic stimulation with IKr.

Quetiapine (ICI204636) is used for the therapy of schizophrenia, and for the treatment of acute manic episodes associated with bipolar I disorder. The mechanism of quetiapine' action is thought by mediated through antagonist activity at serotonin and dopamine receptors. Specifically, the D1 and D2 dopamine, the α1 adrenoreceptor and α2 adrenoreceptor, and 5-HT1A and 5-HT2 serotonin receptor subtypes are antagonized. Quetiapine also can inhibit the histamine H1 receptor.

JP1302 is a selective α2C adrenoceptor antagonist with a Kb value of 16 nM and a Ki of 28 nM for human α2C receptors.JP1302 has antidepressant activity, disrupts the FACT complex and degrades histone H1.JP1302 has been used in the study of neuropsychiatric disorders, acute renal failure, and renal injury.
