Acetohydroxamic acid NEW

1. Clinical Medical Applications (Core Use)

• Treatment of urinary tract infections (UTIs) caused by urease-producing bacteria

  Urease-producing bacteria (e.g., Proteus, Klebsiella, Pseudomonas) can decompose urea in urine into ammonia, leading to alkalization of urine and the formation of magnesium ammonium phosphate (struvite) and calcium phosphate stones (urolithiasis).

  Acetohydroxamic acid inhibits bacterial urease activity, reduces ammonia production, lowers urine pH, and prevents the formation and growth of urinary stones. It is often used as an adjunctive drug combined with antibiotics to treat recurrent UTIs associated with struvite stones, especially for patients who cannot undergo surgical stone removal.

• Adjunctive treatment of Helicobacter pylori (H. pylori) infections

  H. pylori produces urease to neutralize gastric acid and survive in the acidic gastric environment. Although acetohydroxamic acid is not a first-line drug for H. pylori eradication, it can be used as an alternative adjunct in combination with proton pump inhibitors (PPIs) and antibiotics for patients with drug-resistant H. pylori infections, to enhance the eradication effect by inhibiting urease.

2. Industrial Applications

• Metal chelating agent

  The hydroxamic acid group of acetohydroxamic acid has a strong chelating ability with metal ions (e.g., Fe³⁺, Cu²⁺, Ni²⁺). It is used in industrial water treatment to prevent metal ion-induced scaling in pipelines and equipment; it can also be applied in mineral processing as a flotation collector for certain metal ores (e.g., wolframite, tantalite).

• Corrosion inhibitor

  It can form a stable chelate film on the surface of metal equipment, especially for iron and steel products, to reduce corrosion caused by acidic or alkaline media in industrial environments.

3. Scientific Research Applications

• Enzyme inhibition research

  As a classic urease inhibitor, it is widely used in biochemical experiments to study the structure and function of urease, and to screen and develop new urease inhibitors with higher efficiency and lower toxicity.

• Biological mechanism studies

  It is used in cell and molecular biology research to explore the role of urease in bacterial pathogenicity, and to verify the relationship between urease activity and disease progression (e.g., urinary stone formation, gastric mucosal damage).
