PD325901 is a highly selective MEK1/2 inhibitor that suppresses ERK1/2 phosphorylation and downstream signaling. In neuroscience, the MEK/ERK pathway is implicated in synaptic plasticity, memory formation, and neuroinflammation. PD325901 has shown promise in preclinical models of neurodevelopmental and neurodegenerative disorders, including fragile X syndrome and Alzheimer's disease, by modulating aberrant signaling and improving cognitive outcomes.

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.
- Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
- Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
- Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
- QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
- Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity
To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
