Neomycin sulfate, an aminoglycoside antibiotic, exerts antibacterial activity through irreversible binding of the nuclear 30S ribosomal subunit, thereby blocking bacterial protein synthesis. Neomycin sulfate is a known phospholipase C (PLC) inhibitor. Neomycin sulfate potently inhibits both the nuclear translocation of angiogenin and angiogenin-induced cell proliferation and angiogenesis. Neomycin sulfate inhibits IP3-mediated Ca²⁺ release, MgATP-dependent Ca²⁺ uptake, and electrical excitation-evoked skeletal muscle Ca²⁺ transients. Neomycin sulfate depletes gut microbiota in specific mouse models, causes hearing impairment, and kidney damage with prolonged exposure. Neomycin sulfate can be used for the research of cancer.

In Vitro

Neomycin sulfate (10-500 μM; 30 min) inhibits nuclear translocation of angiogenin in HUVE cells with 60% inhibition at 100 μM and residual 14% translocation at 500 μM^[1].
Neomycin sulfate (5-50 μM; 48 h) completely abolishes angiogenin-induced proliferation of HUVE cells at 50 μM, with 49% inhibition at 5 μM and 69% inhibition at 25 μM^[1].
Neomycin sulfate (5-50 μM; 2 h) does not inhibit the ribonucleolytic activity of angiogenin against yeast tRNA at concentrations up to 50 μM^[1].
Neomycin sulfate (0.25-1.25 mM; 6 minutes after cell permeabilization) inhibits IP₃-mediated Ca²⁺ release in saponin-permeabilized RINmSF insulinoma cells in a dose-dependent manner and also inhibits the initial rate of net Ca²⁺ uptake into non-mitochondrial pools^[2].
Neomycin sulfate (1.25 mM) inhibits IP₃-mediated ⁴⁵Ca²⁺ release from saponin-permeabilized rat hepatocytes, with greater inhibition at low IP₃ concentrations^[2].
Neomycin sulfate covalently linked to glass beads avidly binds IP₃ (93% retention) and ATP (97-98% retention) and also binds PIP₂ (70% retention), but binds IP₁ and myo-inositol poorly^[2].

Cell Proliferation Assay^[1]

Cell Line:	human umbilical vein endothelial (HUVE) cells
Concentration:	5, 10, 25, 50 μM
Incubation Time:	48 h
Result:	Inhibited angiogenin-induced proliferation in a dose-dependent, non-linear manner; reduced proliferation by 49% at 5 μM, by 69% at 25 μM, and completely abolished angiogenin-induced proliferation at 50 μM; did not affect basal proliferation or cell viability when used alone.

In Vivo

Neomycin sulfate (4-200 ng; applied to CAM; single dose) at 20 ng per egg completely inhibits angiogenin-induced angiogenesis in the chicken CAM model^[1].
Neomycin sulfate (1 g/L; p.o.; daily; 14 days) as part of a broad-spectrum antibiotic cocktail depletes over 90% of gut microbiota in 7.5-month-old APP/PS1 transgenic mice^[3].
