Biological Activity

Description SL327 is a selective inhibitor for MEK1/2 with IC50 of 0.18 μM/ 0.22 μM, no activity towards Erk1, MKK3, MKK4, c-JUN, PKC, PKA, or CamKII;capable of transport through the blood-brain barrier.
Targets
MEK1 [3] MEK2 [3] AP-1 [3]
0.18 μM 0.22 μM 2.03 μM
In vitro

SL327 is a structural homologue of the specific MKK1/2 inhibitor U0126 with IC50 of 0.18 μM and 0.22 μM for MEK1 and MEK2 respectively. SL327 has no effect on a variety of other kinases, including PKA, PKC, or CamKII. [1]
In vivo

SL327 (50 mg/kg) crosses the blood-brain barrierand and blocks fear conditioning by inhibiting MAPK/ERK phosphorylation. [2] SL327 (30 mg/kg) significantly impairs spatial learning in mice. [3] SL327 (50 mg/kg) blocks cocaine-induced properties. [4]
