IC50: 0.2  μM (MAO-A)[1]

In order to assess whether the protective effect is related to the inhibition of the MAO-A or due to another mechanism, the effect of Brofaromine (BRO) is determined on the activity of MAO-A in cultured cortical cells. It shows, firstly, that cultured cortical cells have a significant MAO-A activity, and secondly, that Brofaromine inhibits the enzyme in a concentration-dependent manner. The IC50 is 0.19 μM for Brofaromine . Hill coefficient is 0.96. The enzyme is almost completely inhibited at 10 μM . Brofaromine inhibits MAO-A activity of our cultured cortical cells in a concentration-dependent manner. The IC50 range of Brofaromine is 0.01 μM to 0.1 μM[1].
