    Etoposide is a topoisomerase II inhibitor that induces DNA strand breaks by preventing the re-ligation of cleaved DNA. This mechanism leads to apoptosis, making etoposide a useful tool in studying DNA damage pathways in neurons. It is also used in models of neurotoxicity and to investigate the role of DNA repair in neurodegenerative conditions.

    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).
