    摘要: The present invention provides a method for producing a disulfonylamine alkali metal salt, including a step of subjecting a disulfonylamine onium salt represented by formula [I] (wherein each of R 1 and R 2 independently represents a fluorine atom or a fluorinated alkyl group having 1 to 6 carbon atoms, provided that at least one of R 1 and R 2 represents a fluorine atom, and each of R 3 , R 4 , R 5 and R 6 independently represents a hydrogen atom or the like) to a cation exchange reaction in an organic solvent, thereby producing a disulfonylamine alkali metal salt represented by formula [II] (wherein M + represents an alkali metal cation, and R 1 and R 2 are as defined in formula [I]), and a step of filtering the organic solvent solution containing the disulfonylamine alkali metal salt through a filter having a particle retention size of 0.1 to 10 µm to obtain a filtrate.

    摘要: The invention relates to dimeric aryl-sulphonamido compounds endowed with inhibitory activity against metalloproteases MMP, having formula (I) below (M)-L-(M') (I), wherein M and M', the same or different from each other, represent the residues of the metalloproteases inhibitors of formula (II), wherein R, R
    1 , R
    2, R
    3 , G and n have the meanings reported in the specification; the invention also refers to the process for their preparation, to pharmaceutical compositions comprising them and to their use as therapeutic agents, particularly in the treatment of degenerative disorders.
