The increasing prevalence of gout has been accompanied by a growing number of patients intolerant to or with disease refractory to the available urate-lowering therapies. This metabolic disease is a common disease with a higher prevalence in men older than 30 years and in women older than 50 years. These findings highlight the need for emerging treatments to effectively lower urate levels. In this view, we describe the xanthine oxidase (XO) inhibitory activities of the synthesized compounds 5a-j and also their antioxidant activities. Compounds 5c, 5d, 5f, 5h, and 5j exhibited good inhibitory activities against XO. On the other hand, compounds 5g and 5j exhibited moderate antioxidant activity.

Polyphenolic plant compounds possess nutritional and pro-healthy potential, reducing the risk of auto-inflammatory and neoplastic diseases. However, their interference with the progression of thyroid gland dysfunctions has remained largely unaddressed. For this purpose, we combined the analyses of phenolic content and antioxidative activity with the thyroid peroxidase (TPO), lipoxygenase (LOX), xanthine oxidase (XO) and cyclooxygenase-2 (COX-2) activity assays, isobolographic approach and the estimation of thyroid cancer cells' proliferation and motility in vitro.

In this study, five seagrass species Halodule uninervis, Thalassia hemprichii, Enhalus acoroides, Cymodocea serrulata, and Syringodium isoetifolium collected from the Mandapam coastal region of Rameswaram (Palk Bay region), Tamil Nadu, India, were selected to identify the antioxidant-rich protein/peptides. The primary objective was to identify the proteins/peptides present in these seagrass filtrates extracted by using four different pH-based buffer extracts and to assess their antioxidant activity. Among the various buffer extracts, 0.

Background: Dementia is a mental condition defined by a severe loss of intellectual ability that interferes with one's occupational or social activities. The rapid increase in the number of patients with dementia and Alzheimer's disease (AD) will result in tremendous consequences for our society and economy. Hypoxanthine is a purine compound that is implicated in the progression of AD.

Purpose: Serum uric acid (SUA) is primarily produced through the hydrolysis of purines in the liver, with its excretion largely handled by the kidneys. Urate transporter 1 (URAT1) inhibitors are known to enhance uric acid elimination via the kidneys, but they also increase the risk of kidney stone formation. Currently, xanthine oxidase (XO) inhibitors are the predominant uric-lowering medications on the market.
