IC50: 8 nM for MEK [1]

PD 198306 is a potent, selective and non-ATP competitive MAPK/ERK-kinase (MEK) inhibitor. MEK is a kinase enzyme which phosphorylates mitogen-activated protein kinase (MAPK).

In vitro: PD 198306 inhibits the isolated MEK at a concentration of 8 nM and inhibits MEK activity in synovial fibroblasts at 30–100 nM, depending on the species. PD 198306 is highly selective for MEK and has a IC50 of >4 uM for c-Src, >1 uM for ERK, >4 uM for cyclin-dependent kinases and >10 uM for phosphatidylinositol 3-kinase [1].

In vivo: Rabbits treated with PD 198306 showd a significant dose-dependent reduction in the level of phospho-ERK-1/2 and a lower level of MMP-1. PD 198306 can partially decrease the development of some of the structural changes in experimental rabbit model of osteoarthritis [1]. PD 198306 dose-dependently blocked static allodynia in both the streptozocin and the chronic constriction injury models of neuropathic pain. These antihyperalgesic effects correlated with a reduction in the elevated levels of active ERK1 and 2 in lumbar spinal cord [2].

Clinical trial: So far, no clinical study has been conducted.
