  Synthesis and Characterization of Metabolites and Potential Impurities of the Antiulcerative Drug Tenatoprazole

  摘要：

  Tenatoprazole (Ulsacare (R)) is a recently developed antiulcerative drug used for the treatment of both erosive and nonerosive gastroesophageal reflux disease. During the bulk synthesis of tenatoprazole, we have observed four impurities (tenatoprazole N-oxide, tenatoprazole sulfone N-oxide, N-methyl tenatoprazole, and desmethoxy tenatoprazole) and two metabolites (tenatoprazole sulfide and tenatoprazole sulfone). The present work describes the synthesis and characterization of these impurities.

  The present invention concerns enantioselective preparation of sulphoxide derivatives or their salts. The method consist in performing an enantioselective oxidation of a sulphur of general formula (I) A-CH 2 —SB, wherein: A is a diversely substituted pyridinyl ring and B is a heterocyclic radical comprising an imidazo-pyridinyl ring, using an oxidizing agent in the presence of a titanium (IV) -based catalyst and a chiral ligand consisting of a cyclic beta or gamma-amino-alcohol, in an organic solvent, followed, if required, by salt formation with a base. The invention is useful for preparing sulphoxides useful in therapeutics.

  Tenatoprazole, a substituted imidazopyridinyl derivative, is an irreversible proton pump inhibitor (PPI), which is used for the prevention and treatment of gastric acid-related diseases. A new highly efficient asymmetric oxidation using cumene hydroperoxide (CHP) as the oxidant in the presence of titanium tetraisopropoxide (Ti(OiPr)(4)) and (+)-(1R,2S)-cis-1-amino-2-indanol, in a polar aprotic solvent at 0-20 degrees C, has been developed to prepare tenatoprazole with an enantiomeric excess of >99%, a chemoselectivity of >90% and a chemical yield of >90% from the corresponding sulfide. This procedure was successfully implemented on scales ranging from 100 mg to multiple kilograms. Detailed studies of the parameters controlling purity and yield for this reaction are presented.
