Basic Info of Zileuton

What is Zileuton?

Asthma is a common chronic disease with a prevalence of about 10% in developed countries, and its morbidity and disability rate are increasing globally. As an important mediator of airway allergic inflammation, the successful study of leukotriene antagonists is a major breakthrough in asthma treatment in recent years.

Zileuton is a novel selective 5-lipoxygenase inhibitor that antagonizes leukotriene synthesis by inhibiting lipoxygenase. Leukotrienes are highly active inflammatory substances synthesized from tetraenoic acid via the lipoxygenase pathway, and play an important role in the pathogenesis of asthma. Zileuton mechanism of action is to effectively control the development of asthmatic inflammation by inhibiting the synthesis of leukotrienes. As a new class of anti-asthmatic drugs, zileuton has certain tracheal protection, tracheal expansion and anti-inflammatory effects. In the United States, the drug has been officially included in the National Asthma Education and Prevention Program in the United States due to its positive efficacy and small side effects, as a long-term treatment for asthma control (the currently included varieties are zafirlukast and zileuton).

The chemical name of zileuton is N-hydroxy-N-[1-(2-benzothiophene)ethyl]urea, which was developed by Abbott Company in the United States and was approved by the FDA in 1997 to be marketed in the United States for prevention and treatment Chronic asthma over 12 years of age.

Zileuton Uses

  1. Zileuton is suitable for asthma, especially the trachea and bronchospasm caused by antigens, aspirin, etc., thereby improving lung function.
  2. Zileuton has obvious anti-allergic and anti-inflammatory effects in vivo and in vitro. Prevents leukotriene synthesis by inhibiting the activity of the initiating enzyme 5-LOX in the leukotriene biosynthesis pathway. It can also antagonize the effect of the leukotriene product LTB4, and inhibit the bronchial constriction and inflammatory effects of leukotrienes.
  3. Zileuton selectively inhibits 5-lipoxygenase biosynthesis for asthma.

Preparation of Zileuton

Using 2-acetoxybenzothiophene as the starting material, the target compound zileuton (4) was synthesized through three steps of oximation, reduction and condensation. The synthesis reaction conditions were mild, the operation was simple, and the efficiency was improved. Its purity can reach more than 99% through HPLC determination, and the reaction equation is as follows::

Great company! thanks from Australia for good product quality, correct product, good customer service using chat.. delivery speed was ok, via FedEx. the Alibaba App finally makes it safer, so good companies like Shandong Zhi Shang can do business with us, I don't have to worry now with Alipay. Everything is safe for me now, I can't go wrong. frst time payments can just use card, the seller never knows your details, only Alibaba does the payment, so the risk is gone, delivery on time is guaranteed, and because the seller can't see your card details, scammers can't use this system, only good companies that do the right thing can make money here. it really is a much better system now.

I general, was very satisfied with the supplier. Basic analyzes (m.p.. FTIR) of the product in our facility confirmed its high quality. Further analyzes are planned, but due to the COVID-19 pandemic, most laboratories in Slovenia are closed.
