Description: PD98059 also known as PD-98059, is a potent and selective inhibitor of MAP kinase kinase (also known as MAPK/ERK kinase or MEK kinase). It mediates its inhibitory properties by binding to the ERK-specific MAP kinase MEK, therefore preventing phosphorylation of ERK1/2 (p44/p42 MAPK) by MEK1/2. MAPK ERK1/2 is involved in TLR-induced production of cytokines.

Biological target: PD98059 is a MEK inhibitor with an IC50 of 5 µM.
In vitro activity: To determine the antiproliferative effects of PD98059 on breast cancer cells, MCF-7 and MDA-MB-231 breast cancer cells were treated with 1, 5, 10 and 20 µM PD98059 for 24 h. As shown in Fig. 1A and B, after incubation of the MCF-7 and MDA-MB-231 cells with 1, 5, 10 and 20 µM PD98059 for 24 h, the expression of phosphorylated MEK1 which is an indicator of MEK1 activation was markedly decreased from 5 to 20 µM compared with the control group. PD98059 inhibited MCF-7 and MDA-MB-231 cell proliferation in a dose-dependent manner using MTT assay (Fig. 1C and D). For example, the cell growth inhibition ratio was increased from 4.7% at the dose of 1 µM to 33.1% at the dose of 50 µM in MCF-7 breast cancer cells. Similarly, the cell growth inhibition ratio was increased from 4.2% at the dose of 1 µM to 40.5% at the dose of 50 µM in the MDA-MB-231 breast cancer cells.

In vivo activity: In CCI (chronic constriction injury) exposed rats single intrathecal PD98059 (2.5 mcg) administration produced significant antiallodynic effect after 30 min as assessed at day 7 by the von Frey test (18.5 g ± 0.55, n = 10; Fig 4C and 4D). Single intrathecal PD98059 (2.5 mcg) administration enhanced morphine-induced analgesia (24.2 ± 0.63, n = 8, Fig 4C). Single intrathecal PD98059 (2.5 mcg) administration also enhanced buprenorphine-induced analgesia (23.25 ± 0.62, n = 7, Fig 4D).
