On the basis of the results obtained in previous series of AMPA potentiators belonging to 3,4-dihydro-2H-benzo- and 3,4-dihydro-2H-pyrido-1,2,4- thiadiazine 1,1-dioxides, the present work focuses on the design of original isosteric 3,4-dihydro-2H-thieno-1,2,4-thiadiazine 1,1-dioxides. Owing to the sulfur position, three series of compounds were developed and their activity as AMPA potentiators was characterized. In each of the developed series, potent compounds were discovered. After screening the selected active compounds on a safety in vivo test, 6-chloro-4-ethyl-3,4-dihydro-2H-thieno[2,3-e]-1,2,4- thiadiazine 1,1-dioxide (24) appeared as the most promising compound and was further evaluated. Its effects on long-term potentiation in vivo and on AMPA-mediated noradrenaline release were measured to predict its potential cognitive enhancing properties. Finally, an object recognition test performed in mice revealed that 24 was able to significantly enhance cognition, after oral administration, at doses as low as 0.3 mg/kg. This study validates the interest of the isosteric replacement of the benzene or pyridine nuclei by the thiophene nucleus in the ring-fused thiadiazine dioxides class of AMPA potentiators.

Two series of novel thienopyrrole inhibitors of recombinant human liver glycogen phosphorylase a (GPa) which are effective in reducing glucose output from rat hepatocytes are described. Representative compounds have been shown to bind at the dimer interface site of the rabbit muscle enzyme by X-ray crystallography.

A process for preparing a compound of formula (I) where R4 and R5are as defined in the specification; and R6 is hydrogen or a protecting group, which process comprises cyclisation of a compound of formula (II) where R4, R5and R6 are as defined in relation to formula (I) and R7is a nitrogen-protecting group, and removing protecting group R7-, and thereafter if desired or necessary, removing any protecting group R6 to obtain the corresponding carboxylic acid. Novel intermediates and the use of the products in the preparation of pharmaceutical compounds is also described and claimed

The Beckmann rearrangement of 2-acetylthiophene, 5-methyl-2-acetylthiophene, 5-chloro-2-acetylthiophene, and 2,5-dichloro-3-acetylthiphene oxime benzenesulfonates to the corresponding acetamidothiophenes was carried out by heating with an aqueous methanol solution of sodium acetate.This method can be used for the preparative synthesis of 2-acetamidothiophene and 2,5-dichloro-3-acetamidothiophene.
