Flavoxate hydrochloride (Rec-7-0040; DW61) is an orally active L-type Ca²⁺ channel inhibitor and antispasmodic. Flavoxate hydrochloride inhibits cyclic adenosine monophosphate production by blocking voltage-dependent inward Ba²⁺ currents, regulating the brainstem micturition center, and stimulating G protein-coupled receptors. Consequently, Flavoxate hydrochloride induces relaxation of bladder smooth muscle and inhibits isovolumetric rhythmic contractions. Flavoxate hydrochloride effectively increases bladder capacity and alleviates symptoms of urgent urination frequency and pollakiuria caused by overactive bladder. Flavoxate hydrochloride can be used in research on overactive bladder and related voiding dysfunctions.

(-)-MDO-NPA is an N-propylnorapomorphine analog and a D1R/D2R dual-target ligand. (-)-MDO-NPA has EC₅₀ values of 1949 nM (D1R) and 520 nM (D2R) for β-arrestin. (-)-MDO-NPA has EC₅₀ values of 717.5 nM (D1R) and 7.7 nM (D2R) for cAMP. (-)-MDO-NPA can be used in the research of dopamine-related diseases such as Parkinson’s disease.

(S)-SKF-77434 (Compound 11) ((S)-APB) is an enantiomer of SKF-77434 (HY-103417). (S)-SKF-77434 shows an affinity for the D₁ receptor with an IC₅₀ of 2800 nM. (S)-SKF-77434 can be used in the research of neuropsychiatric disorders.

L-750667 is a selective dopamine D4 receptor antagonist ligand. ¹²⁵I-labeled L-750667 can specifically bind to dopamine D4 receptors in the rat retina, with a K_d value of 0.06 nM. L-750667 is involved in the regulation of the light-sensitive cAMP pool.

UCSF34 (Compound 54) is a Haloperidol (HY-14538) analogue. UCSF34 binds to the human D₂L receptor, with an estimated pK_i of 7.49. UCSF34 can be used in the research of schizophrenia.

m,p-Dimethyl PPE is a D4 dopamine receptor ligand. m,p-Dimethyl PPE promotes GDP/GTP exchange of the G protein α-subunit, dissociates the receptor-G protein complex, stabilizes the low-affinity receptor state, and inhibits adenylate cyclase activity. m,p-Dimethyl PPE inhibits Forskolin (HY-15371)-induced melatonin synthesis in retinal photoreceptor cells and reduces the efficacy of full agonists when used in combination. m,p-Dimethyl PPE can be used in studies related to attention-deficit hyperactivity disorder.

Piquindone (Ro 22-1319) is a potent antipsychotic agent. Piquindone binds to a D₂ dopaminergic receptor subtype in a sodium-dependent manner. Piquindone can be used in the research of schizophrenia.

Cinuperone is a multi-target competitive receptor ligand and σ receptor antagonist that acts on Dopamine D1, σ, Dopamine D1, and 5-HT₂ receptors. Cinuperone shows significantly higher affinity for σ receptors than for Dopamine D1 receptors, and only exhibits moderate binding activity for dopamine D2 receptors. Cinuperone can be used in the research of central nervous system diseases.

Spectramide is a blood-brain barrier-permeable, reversible, and selective dopamine D₂ receptor ligand. Spectramide shows no strong interactions with dopamine D₁ receptors, dopamine uptake sites, adrenergic receptor systems, cholinergic receptor systems, or 5-HTR systems. Spectramide can be labeled with ¹¹C or ¹²³I isotopes for use in PET or SPECT. Spectramide preferentially accumulates in the striatum with low uptake in other brain regions, and its accumulation can be blocked by pre-administration of Haloperidol (HY-14538).
