Beschreibung
Acetohydroxamic acid is a potent, non-competitive and irreversible inhibitor of
bacterial urease (Ki≈lO
-7M). This enzyme, which is widely distributed in plants
and bacteria, but not in mammalian cells, catalyzes the decomposition of urea to
ammonia. Elevated urinary ammonia levels can reduce the antibacterial effectiveness
of a number of agents. Thus, acetohydroxamic acid is useful as adjunctive
therapy to decrease urinary ammonia and alkalinity in patients with chronic
urea-splitting urinary infection. Such infections are a leading cause of recurring
complications and death in paraplegics.
Chemische Eigenschaften
White Crystalline Solid
Verwenden
Acetohydroxamic acid is a potent inhibitor of bacterial urease activity and reduces urinary ammonia levels. 2-Acetohydroxamic acid loaded floating microspheres forms an efficient drug delivery system for the treatment of Helicobacter pylori.
Acetohydroxamic acid was used:
to study the mechanism of complexation of iron (III) with acetohydroxamic acid.
to study the inhibitory mechanism of lansoprazole and omeprazole on Helicobacter pyloni.
in urease inhibition studies.
for in situ generation of nitrosocarbonylmethane as a Diels-Alder dienophile.
Used in urease inhibition studies and for in situ generation of nitrosocarbonylmethane as a Diels-Alder dienophile.

Nebenwirkungen
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have:
pounding heartbeats or fluttering in your chest;
signs of a blood clot in your leg --pain, swelling, warmth, or redness in one or both legs;
signs of a red blood cell disorder --pale or yellowed skin, dark colored urine, fever, confusion or weakness.
Common side effects may include:
headache during the first 2 days of treatment;
skin rash, warmth, tingling or redness (especially if you drink alcohol while taking acetohydroxamic acid);
upset stomach, nausea, loss of appetite;
depressed mood;
anxiety, tremors, nervousness;
hair loss.
Sicherheitsprofil
Moderately toxic by intraperitonealroute. An experimental teratogen. Other experimentalreproductive effects. Mutation data reported. When heatedto decomposition it emits toxic fumes of NOx.
