生物活性

Tacrine is an effective oral acetylcholine (AChE) inhibitor (IC50 = 109 nM) and also acts as an active substrate for CYP1A2. Tacrine can restore cognitive dysfunction in elderly rats. Tacrine can cause liver toxicity and is used in research related to Alzheimer's disease[1][2][3][4].

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.
