A number of N- and S-substituted uracil and thiouracil glycosides were synthesized by coupling reaction of 5,6-dibenzyle pyrimidine derivatives with the corresponding acetobromosugar. The synthesized compounds were tested for their antiviral activity against hepatitis B virus. Plaque reduction infectivity assay was used to determine virus count reduction as a result of treatment with tested compounds which showed moderate to high antiviral activities.

Thiouracil (2-thiouracil) is a thyrostat used to promote weight gain in cattle. However, its use is prohibited within the European Union (EU), necessitating the monitoring of its presence in bovine urine for beef exports to the EU. In this study, we present the development and validation of a quantitative method for the determination of 2-thiouracil, 4-thiouracil, and 6-methyl-2-thiouracil in bovine urine using liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Article Synopsis
- The study investigates new complexes formed between gallium(III) and various thiouracil derivatives, examining their properties in aqueous solutions at low concentrations.
- The research employs techniques like potentiometric titration and spectroscopy to analyze the complexes' fluorescence, stability, and how pH affects these factors involving coordination with nitrogen, sulfur, and oxygen atoms.
- The results indicate these complexes may have promising future applications in biomedicine, particularly as potential antibacterial and anticancer agents, suggesting a need for further research.
A comparative study on the clinical efficacy and pregnancy outcomes of methimazole and propylthiouracil in managing pregnancy complicated with hyperthyroidism.

The objective of the study was to compare the clinical efficacy and pregnancy outcomes of methimazole and propylthiouracil in managing hyperthyroidism during pregnancy. This retrospective analysis included 100 pregnant women with hyperthyroidism, who were divided into two groups: the methimazole group (Group A) and the propylthiouracil group (Group B). Indicators such as thyroid function, liver function, pregnancy outcomes, and newborn health were closely monitored.

We report a case of Graves' disease in a patient who initially received carbimazole therapy, which was switched to propylthiouracil due to adverse effects. After 14 months of propylthiouracil therapy, the patient developed cutaneous ANCA-associated vasculitis. Prompt cessation of propylthiouracil and topical treatment led to complete resolution of the skin lesions.

Article Synopsis
- - The study explored how cordycepin affects renal damage caused by hypothyroidism using a rat model induced by propylthiouracil (PTU), observing general health, thyroid and kidney function, blood lipids, and tissue damage.
- - Findings showed that hypothyroid rats experienced renal damage and increased blood lipids as the disease progressed, with higher levels of MCP-1 indicating podocyte damage.
- - Cordycepin was found to enhance thyroid function and significantly alleviate kidney damage, reducing both renal harm and blood lipid levels, while also decreasing the expression of damage markers MCP-1 and Desmin, indicating potential protective effects for renal health.
