PD98059,167869-21-8,IC-0224717

PD98059 is a potent and selective MEK inhibitor with an IC50 of 2 μM. PD98059 binds to the inactive form of MEK, thereby preventing the upstream kinase from activating MEK1/2. Besides, PD98059 is a ligand for the AHR and functions as an AHR antagonist[1-3].

PD98059(10 µM PD98059;14days) combined with TGF-β1 transforms human UDSCs (hUDSCs) into smooth muscle cells (SMCs)[4]. PD98059 (10 μM PD98059 ;24 h) suppresses the ERK pathway and the epithelial mesenchymal transition process(EMT) process in low dose cisplatin-resistant ovarian cancer cells(SKOV-3/DDP) [5]. PD98059 arrested Hec50co cells at the G0/G1 phase, the combination with PTX treatment increased accumulation at both the G0/G1 and G2/M phase[6]. PD98059(1, 5, 10, 20 and 50 µM；24h) inhibited MCF-7 and MDA-MB-231 cells proliferation in a dose-dependent manner[7].

PD98059(5 mg/kg/day; i.p; 2 weeks) treatment reduced adverse effects, including micronucleus (MN) formation, lipid peroxidation, and glutathione(GSH) oxidation in the EAE model[8].PD98059(0.15/0.3mg/kg PD98059; i.v. gtt) protects the brain against mitochondrial-mediated apoptosis and autophagy at 24 h post-resuscitation in rats subjected to cardiac arrest/cardiopulmonary resuscitation (CA/CPR), which is linked with the downregulation of dynamin-related protein 1 (Drp1) expression[9]. Treatment of mice with PD98059(10mg/kg; i.p; bolus) attenuated the peritoneal exudation and the migration of polymorphonuclear cells caused by zymosan[10].
