MLS1547 is a small-molecule, G protein-biased agonist of the dopamine D2 receptor used in research to probe receptor signaling bias. It preferentially stimulates G protein-mediated signaling with micromolar potency while showing reduced β-arrestin recruitment, making it useful for studies of biased agonism and D2 receptor pharmacology.

• Preferentially activates G protein signaling over β-arrestin pathways.
• D2 receptor agonist activity (Ki ≈ 1.2 μM; EC50 ≈ 0.37 μM).
• Antagonizes dopamine-stimulated β-arrestin recruitment (IC50 ≈ 9.9 μM).
• High purity suitable for biochemical assays (≥98% HPLC).
• Supplied in small research quantities for laboratory studies.
• Store refrigerated at +4 °C to maintain stability.
