An intracerebroventricular injection of (+)-Coclaurine (d-Coclaurine; 50 μg) produces a slight increase in 3,4-dihydroxyphenylacetic acid level and a significant increase in homovanillic acid level in the mouse striatum. (+)-Coclaurine blocks postsynaptic but not presynaptic dopamine receptors in the mouse striatum.
