Deprotektive Alkylierung: Eine Plattform zur Umsetzung von Alkoholen zu Aminen mittels Nonafluormesitylensulfonamiden

Angewandte Chemie, EarlyView.
Die direkte Umwandlung von Alkoholen in tertiäre oder sekundäre Amine in einem Reaktionsschritt unter Verwendung von Nms‐Amiden wird beschrieben. Die Transformation zeichnet sich durch eine breite Toleranz gegenüber verschiedenen funktionellen Gruppen und eine hohe Stereospezifität aus, was ihre Eignung für die Synthese isotopenmarkierter Arzneimittel ...

Successful febuxostat desensitization in a patient with febuxostat hypersensitivity: A Malaysian experience

, 2017
Over the years, allopurinol has been widely used as the preferred choice of urate lowering therapy in patients with gout. However, its role in patients with renal impairment is limited; and adverse reactions are well documented.

Remote Desaturation of Unprotected Amines and C─H Amination of Alkanes by Polarity‐Matched N‐Radical Cations

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Highly electrophilic N‐radical cations enable efficient and selective H‐atom transfer (HAT) of unprotected amines. In this exceedingly practical strategy, simple CuCl catalyzes an interrupted Hofmann–Löffler–Freytag (HLF) reaction to afford δ desaturated amines, aza‐heterocycles, and C─H aminated alkanes without protecting groups.

A New Regimen for Induction of Metabolic Syndrome and the Effect of Febuxostat in Ovariectomized Female Albino Rats

SVU - International Journal of Medical Sciences, 2021
Background: Metabolic syndrome (MetS) is increasing worldwide and correlates with serum uric acid and high fat combined with highfructose diet (HFFD). Fat raises triglycerides. Fructose increases uric acid. We hypothesized that HFFD in menopause may have

Deprotective Alkylation: A Platform for Alcohol‐to‐Amine Interconversion Using Nonafluoromesitylenesulfonamides

Angewandte Chemie International Edition, EarlyView.
The straightforward conversion of alcohols to tertiary or secondary amines employing Nms‐amides in a single operation is described. The transformation features broad functional group tolerance and high stereospecificity, underscoring its utility in the synthesis of isotope‐labeled pharmaceuticals.

African American patients with gout: efficacy and safety of febuxostat vs allopurinol

BMC Musculoskeletal Disorders, 2012
Background African Americans are twice as likely as Caucasians to develop gout, but they are less likely to be treated with urate-lowering therapy (ULT).

Cardiovascular Safety of Febuxostat and Allopurinol in Hyperuricemic Patients With or Without Gout: A Network Meta-Analysis

Frontiers in Medicine, 2021
Background: Hyperuricemia is a common metabolic disease and has become a public health problem because of its increasing prevalence and association with comorbidities.

Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.

Triangulating Evidence on Serum Uric Acid and Cancer Risk: Consistent Inverse Associations With Lung Cancer

Cancer Science, EarlyView.
Using both conventional observational and Mendelian randomization (MR) analyses in the same Japanese community‐dwelling population, the evidence consistently supported an inverse association between the serum uric acid level and lung cancer risk. ABSTRACT We examined the association between serum uric acid (UA) levels and cancer incidence through a ...
