The present invention relates to compounds of formula (I): Formula (I) wherein Q is selected from O or S; L is a saturated or unsaturated, optionally substituted C.sub.1-C.sub.12 hydrocarbylene group optionally including one or more heteroatoms N, O or S; R.sup.1 is —NR.sup.3R.sup.4, —OR.sup.5, —(C═NR.sup.6)R.sup.7, —(CO)R.sup.8, —CN, —N.sub.3, a quaternary ammonium group or an optionally substituted heterocycle; R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are each independently hydrogen or a saturated or unsaturated, optionally substituted C.sub.1-C.sub.10 hydrocarbyl group optionally including one or more heteroatoms N, O or S; wherein optionally L and R.sup.3, or L and R.sup.4, or R.sup.3 and R.sup.4, or L and R.sup.5, or L and R.sup.6, or L and R.sup.7, or R.sup.6 and R.sup.7, or L and R.sup.8 together with the atom(s) to which they are attached may form a 3- to 12-membered, saturated or unsaturated, optionally substituted cyclic group; and R.sup.2 is a cyclic group substituted at the a-position, wherein R.sup.2 may optionally be further substituted; provided that the atom of L which is attached to the sulfur atom of the sulfonylurea group is a carbon atom and is not a ring atom of a heterocyclic or aromatic 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 NLRP.sub.3. ##STR00001##

A family of novel diazirine-based molecules as well as methods of manufacture and uses thereof are disclosed. These compounds allow non-functionalized polymers, such as polyolefins, to crosslink via C—H insertion. Such a C—H insertion process is useful, for example, for forming protective topical coatings on low surface energy films, for the covalent adhesive bonding of such films, or for creating rigid 3-dimenional polymeric structures by in-situ doping and activation of the crosslinker. The crosslinkers can be activated thermally, by UV radiation or by an electric potential.
