PI3K inhibitor - Autophagy Inhibitor

Wortmannin is a cell-permeable, fungal metabolite that acts as a potent, selective and irreversible inhibitor of phosphatidylinositol 3-kinase (PI3K) [1].

There is increasing evidence of the involvement of PI3K in Toll-like receptor (TLR) signaling [2]. Inhibition of PI3K with wortmannin enhances TLR-mediated inducible nitric-oxide synthase (iNOS) expression, activates NF-κB and up-regulates cytokine mRNA production [3].

Furthermore, PI3K is required for autophagy [4]. Autophagy is a complex pathway in which cell material can be sequestered and delivered to the lysosome for degradation. Inhibition of PI3K with wortmannin can inhibit autophagic sequestration [4].
