Chroman 1 is a highly potent ROCK2 inhibitor, with an IC50 of 1 nM.

IC50 & Target[1]


1 nM (IC50)


150 nM (IC50)

In Vitro

Chroman 1 is a highly potent ROCK2 inhibitor, with an IC50 of < 1 nM. Chroman 1 also shows inhibitory activities against MRCK, with an IC50 of 150 nM, but has no effect on PKA (IC50, > 20000 nM) or AKT1 (IC50, > 20000 nM)[1].

Kinase Assay

Assays are performed using the HTRF KinEASE STK S2 kit. A 5 μL mixture of 1 μM STK2 substrate and 20 μM ATP in STK-buffer is added to the wells. Inhibitor (including Chroman 1, 20 nL) at various concentrations is then dispensed. Reaction is started by addition of 0.5 nM ROCK-II in STK-buffer (5 μL). After 4 h at room temperture (rt), the reaction is stopped by addition of 10 μL mixture of 1× STK antibody-Cryptate in detection buffer and 62.5 nM Sa-XL in detection buffer. After 1 h at rt, the plates are read on the Viewlux in HTRF mode[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
