  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.

  The reaction of substituted oxazoles with 4-phenyl-3H-1,2,4-triazole-3,5(4H)-dione (PTAD) or diethyl azodicarboxylate gave the corresponding 1,2,4-triazoline derivatives through formal [3+2] cycloaddition accompanying ring opening of oxazoles. The molecular structure of an adduct of 5-methoxy-4-methyl-2-(p-tolyl)oxazole with PTAD was determined by means of X-ray crystallography.

  [Au(1‐κP)2][SbF6]. The particular combination of a firmly coordinated (phosphane) and a dissociable (nitrile) donor moieties renders complexes 3/3′ attractive for catalysis because they can serve as shelf‐stable precursors of coordinatively unsaturated AuI fragments, analogous to those that result from the widely used [Au(PR3)(RCN)]X catalysts. The catalytic properties of the Au‐1 complexes were evaluated in model
