Product Description
Potent and specific inhibitor of  phosphoinositide 3-kinase (PI(3)K), myosin light chain kinase and of neutrophil and formyl-Met-Leu-Phe-mediated phospholipase D activation. Strongly inhibits autophagy (proteolysis). Markedly potentiates the LPS-induced nitric oxide (NO) production from macrophages. Induces in vivo Alzheimer-like hyperphosphorylation in tau.
