contain a functionalized ester group at 17 alpha has been prepared and examined to separate their systemic activity from topical antiinflammatory activity. Introduction of the functionalized ester group at 17 alpha was carried out by an acid-catalyzed formation of cyclic orthoesters with 17 alpha,21-hydroxyl groups of corticosteroids and subsequent acid-catalyzedhydrolysis. As for the functional group

conditions, among all tested ionicliquids the 5,5-membered [R-3C-im][NTf2] ionicliquids were most stable to solvent deuterium isotope exchange while the previously reported [bdmim][NTf2] ionicliquid was 50% deuterium exchanged at its C-2 methyl in 30 min at ambient temperature. Under identical condition, the commonly used [bmim][NTf2] ionicliquid was deuterium exchanged instantaneously at its C-2
An affinity ionic liquid, based on biomolecular recognition, was developed and found to be capable of quantitative partitioning of biomacromolecules from aqueous buffer to ionic liquid.

The present invention provides for certain sulfonyl ureas and related compounds which have advantageous properties and show useful activity in the inhibition of activation of the NLRP3 inflammasome. Such compounds are useful in the treatment of a wide range of disorders in which the inflammation process, or more specifically the NLRP3 inflammasome, have been implicated as being a key factor.
