Product Description

Aminoglycoside antibiotic that inhibits translation by binding to the small subunit of prokaryotic ribosomes. Inhibitor of phospholipase C (PLC) due to binding to inositol phospholipids. Neomycin inhibits phosphatidylcholine-phospholipase D activity. Blocks voltage sensitive Ca²⁺ channels without affecting Na⁺/Ca²⁺ antiporters in nerve cells.

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.
