Target	Dopamine Receptor serotonergic receptor
In Vitro	Asimilobine (0.05-0.2 μM; for 24 h) shows a significant inhibition of intracellular dopamine levels in a concentration-dependent manner with an IC50 value of 0.13 μM[2]. Asimilobine (0.15 μM) inhibits tyrosine hydroxylase (TH) and aromatic L-amino acid decarboxylase (AADC) activities at 24 h[2]. Asimilobine also decreases TH mRNA levels and intracellular cyclic AMP levels[2].
