4-FPBUA

4-FPBUA is a semisynthetic analog of usnic acid (HY-W015883) that can enhance cellular blood-brain barrier (BBB) function and increase the transport of Amyloid β (Aβ) across monolayer cells. 4-FPBUA is also an inhibitor of mTOR, capable of enhancing cellular Autophagy, thereby reversing BBB disruption in vivo and being utilized in research for Alzheimer's disease[1].
