Dye and compositions to monitor the multistep protein aggregation process in both test tubes and live cells are provided. These dyes can detect misfolded protein oligomers and distinguish insoluble protein aggregates from misfolded oligomers. Applications of these dyes include measuring kinetics of protein aggregation, monitoring aggregation of specific proteins in intact live cells, monitoring aggregation of cellular proteome in intact live cells, and tracking the time course of protein aggregation in cells under stress conditions.

The present invention relates to sulfonylureas and sulfonylthioureas comprising a 5-membered nitrogen-containing heteroaryl ring attached to the sulfonyl group, wherein the heteroaryl ring is substituted with a nitrogen-containing group R.sup.1′ wherein R.sup.1 contains from 1 to 7 atoms other than hydrogen or halogen. 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.

The disclosure relates to compounds that act as inhibitors of epidermal growth factor receptor (EGFR); pharmaceutical compositions comprising the compounds; and methods of treating or preventing kinase-mediated disorders, including cancer and other proliferation diseases.

The present invention refers to substituted imidazolium sulfuranes, the use thereof for the transfer of a CN group or an alkyne group.

The present invention relates to compounds of formula (I), wherein Q is selected from O or S; R.sup.1 is a 5- or 6-membered heteroaryl group consisting of one or more carbon atoms, and one or more nitrogen and/or oxygen atoms, and substituted with a monovalent, optionally substituted cycloalkyl, cycloalkenyl or heterocyclic group, wherein the 5- or 6-membered heteroaryl group of R.sup.1 may optionally be further substituted; R.sup.2 is an ,-substituted cyclic group which may optionally be further substituted; R.sup.3 and R.sup.4 are each independently hydrogen, halogen, OH, NH.sub.2, CN, R.sup.5, OR.sup.5, NHR.sup.5 or N(R.sup.5).sub.2; or R.sup.3 and R.sup.4 together with the carbon atom to which they are attached may form a 3- to 7-membered saturated or unsaturated, optionally substituted cyclic group; and R.sup.5 is independently an optionally substituted C.sub.1-C.sub.4 alkyl group. 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 NLRP3.
