The present invention relates to compounds of formula (I) wherein Q is selected from O or S; R.sup.1 is a non-aromatic heterocyclic group comprising at least one ring nitrogen atom, wherein R.sup.1 is attached to the sulfur atom of the sulfonylurea group by a ring carbon atom, and wherein R.sup.1 may optionally be substituted; and R.sup.2 is a cyclic group substituted at the ?-position, wherein R.sup.2 may optionally be further substituted. The present invention further relates to salts, solvates and prodrugs of such compounds, to pharmaceutical compositions comprising such compounds, and to the use of such compounds in the treatment and prevention of medical disorders and diseases, most especially by the inhibition of NLRP.sub.3. ##STR00001##

Bifunctional compounds that increase uric acid excretion and reduce uric acid production. Methods of using these compounds for reducing uric acid levels in blood or serum, for treating disorders or uric acid metabolism, and for maintaining normal uric acid levels in blood or serum are provided. Pharmaceutical compositions comprising the bifunctional compounds are also provided.

The invention relates to medicine, in particular to gastroenterology, and lies in the field of treatment of liver diseases of various origins. For this purpose, the hepatoprotective agent that is introduced to the patient is embodied as derivatives of bis(2-thio-4,6-dioxo-1,2,3,4,5,6-hexahydropyrimidine-5-yl) arylmethanes. The method provides reduction of the manifestations of cytolysis under the influence of damaging agents and a statistically significant reduction of dysproteinemia, it accelerates restoration of detoxifying processes of the liver, increases induction of endogenic interferon alfa and, consequently, makes the protection of liver cells during hepatitides of various origins more effective.
