The present invention is related to azole derivatives notably for use as pharmaceutically active
compounds, as well as to pharmaceutical formulations containing such azole
derivatives. Said azole derivatives are modulators of the protein kinase signalling
pathways, particularly the one involving c-Jun N-terminal kinase and/or Glycogen
Kinase Synthase 3. The present invention is furthermore related to novel azole
derivatives as well as to methods of their preparation. X is O, S or NR0,
with R0 being H or an unsubstituted or substituted C1 -C6
alkyl; A is 2-pyridyl, 3-pyridyl, 4-pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl
or triazinyl group.

Abstract Using histamine as lead molecule, a library of (hetero)aryl substituted thiazol-2,4-yl derivatives incorporating pyridine as proton shuttling moiety were obtained and investigated as activators of human carbonic anhydrase (CA, EC 4.2.1.1) isoforms I, II, VII and XIV. Somederivatives displayed good activating and selectivity profiles. This study provides an interesting opportunity to study

GPR91, a 7TM G-Protein-Coupled Receptor, has been recently deorphanized with succinic acid as its endogenous ligand. Current literature indicates that GPR91 plays role in various pathophysiology including renal hypertension, autoimmune disease and retinal angiogenesis. Starting from a small molecule high-throughput screening hit 1 (hGPR91 IC(50): 0.8 mu M)-originally synthesized in Merck for Bradykinin B(1) Receptor (BK(1)R) program, systematic structure-activity relationship study led us to discover potent and selective hGPR91 antagonists e.g. 2c, 4c, and 5g (IC(50): 7-35 nM; >1000 fold selective against hGPR99, a closest related GPCR; > 100 fold selective in Drug Matrix screening). This initial work also led to identification of two structurally distinct and orally bio-available lead compounds: 5g (%F: 26) and 7e (IC(50): 180 nM; > 100 fold selective against hGPR99; %F: 87). A rat pharmacodynamic assay was developed to characterize the antagonists in vivo using succinate induced increase in blood pressure. Using two representative antagonists, 2c and 4c, the GPR91 target engagement was subsequently demonstrated using the designed pharmacodynamic assay. (C) 2011 Elsevier Ltd. All rights reserved.
