, (2018/01/17)
The present invention relates to benzodiazepine derivative compounds of formula (I), or pharmaceutically acceptable salts thereof. The present benzodiazepine compounds are useful Clostridium difficile inhibitors in the treatment of Clostridium difficile infection in humans. The present invention provides a pharmaceutical composition containing benzodiazepine compounds of formula (I) and a method of making as well as a method of using the same in treating patients infected with Clostridium difficile infection by administering the same. The compounds of the present invention may be used in combination with additional antibiotics or anti-toxin antibody drugs.

In the first systematic study of thiopyranopyridines in which the sulphur atom is separated from the pyridine ring by one carbon atom, the four isomeric enol esters, ethyl 5-hydroxy-8H-thiopyranopyridine-6-carboxylate (4b), ethyl 8-hydroxy-5H-thiopyranopyridine-7-carboxylate (5b), and ethyl 4-hydroxy-1H-thiopyrano- and pyridine-3-carboxylate (6b) and (7b), have been synthesised.Improved methods for the preparation of their pyridine precursors are described.With phenylhydrazine, the enol esters (4b) - (7b) give condensed pyrazole derivatives (15) - (18), which have dipolar structures; with hot mineral acid they undergo decarboxylative hydrolysis, to give the corresponding oxothiopyranopyridines (4a) - (7a).
