PP1 is a potent and selective inhibitor of Src family protein tyrosine kinases. It binds to the ATP-binding site of tyrosine and serine/threonine kinases, displaying high selectivity over ZAP-70 and JAK2. In neuroscience, PP1 is used to study the role of Src kinases in synaptic plasticity, neuronal development, and neuroinflammation. It is particularly useful in models of excitotoxicity and neurodegeneration, where Src signaling contributes to calcium dysregulation and cell death.

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).
