NW-1689 is a process-related impurity of safinamide mesilate (SAFM). SAFM can be used for the study of Parkinson's disease (PD). It is a highly selective and reversible inhibitor of monoamine oxidase-B (MAO-B) and also blocks sodium channels and N-type calcium channels. These effects of SAFM help reduce the breakdown of dopamine and inhibit the release of glutamate. NW-1689 has a similar chemical structure to SAFM and has some similar pharmacological effects as SAFM, and can be used in Parkinson's disease research.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
