Biological Activity
Aftin-4 is an Amyloid-β42 (Aβ42) inducer.
In Vitro
Aftin-4 selectively and potently increases Aβ1-42 in N2a cells, primary neurons, and brain lysates, with an EC50 value around 30 μM[1].
In Vivo
Aftin-4 increases Aβ1-42 levels in vivo in mice and provokes rapidly a sustained toxicity highly reminiscent of Alzheimer’s disease (AD). Aftin-4 is administered at increasing doses, between 3 and 20 nmol/mouse, into the lateral ventricle and animals are sacrificed at various time points, between 3 to 14 days after injection. The hippocampus is dissected out the contents in Aβ1-40 or Aβ1-42 is determined using a mouse ELISA assay. Aftin-4 dose-dependently and significantly increases Aβ1-42 content, up to +216% at the highest dose tested[1].
