  Probing the ‘bipolar’ nature of the carbonic anhydrase active site: Aromatic sulfonamides containing 1,3-oxazol-5-yl moiety as picomolar inhibitors of cytosolic CA I and CA II isoforms

  摘要：

  A series of potent inhibitors of human carbonic anhydrase (CA) isoforms I and II has been prepared via a direct, chemoselective sulfochlorination of a range of 1,3-oxazolyl benzenes and thiophenes, followed by primary sulfonamide synthesis. The latter functionality is a known zinc-binding group (ZBG) responsible for anchoring the inhibitors to the CA's zinc metal ion. The compound's periphery as well as the overall scaffold geometry was designed to enable optimal interactions with the two distinct sides of the enzyme's active site, one of which is lined with hydrophobic residues and while the other is predominantly hydrophilic. As a result, several compounds inhibiting the therapeutically important cytosolic CA I and CA II in picomolar range have been identified. These compounds are one of the most potent CA inhibitors identified to-date. Not only the remarkable (>10 000-fold), cytosolic CA I and CA II selectivity vs. the membrane-bound CA IX and CA XII isoforms, but also the pronounced CA II/I selectivity observed in some cases, allow considering this series as a set of isoform-selective chemical biology tools and promising starting points for drug candidate development.

  A continuous flow process is presented, which directly converts isoxazoles into their oxazole counterparts via a photochemical transposition reaction. This results in the first reported exploitation of this transformation to establish its scope and synthetic utility. A series of various di- and trisubstituted oxazole products bearing different appendages including different heterocyclic moieties were

  A silver‐induced cycloaddition of isocyanides with acyl chlorides has been developed. This transition metal‐catalyzed strategy provides an effective and scalable approach for the formation of 2,5‐disubstituted oxazoles in good to high yields. The employed silver‐based MOF catalyst can be efficiently recycled without compromising the yield.
