Biological Activity for LY 450139

LY 450139 is a γ-secretase pseudo-inhibitor. Inhibits Aβ secretion from cells in vitro and increases accumulation of γ-secretase products and long Aβ species in vitro and in vivo. Also attenuates the accumulation of activated microglia and neurological injury in a traumatic brain injury animal model.
