The present invention relates to compounds of the following formula (I), wherein: m represents an integer being equal to 0, 1, 2, 3, 4, 5 or 6, X represents a simple bond or a radical &#x2014;CHRwherein Rrepresents:&#x2014;a hydrogen atom, or&#x2014;a linear or branched, possibly interrupted by up to 3 heteroatoms selected from O, S or N and/or possibly substituted, (C-C)-alkyl, R, Rand Rrepresent independently from each other:&#x2014;a hydrogen atom, or&#x2014;a linear or branched (C-C-alkyl or (C-C)-acyl R5 represents:&#x2014;a hydrogen atom, or&#x2014;a linear or branched, possibly substituted, (C-C)-alkyi possibly substituted and possibly interrupted by up to 3 heteroatoms selected from O, S or N, Rrepresents:&#x2014;a hydrogen atom, or&#x2014;a linear or branched possibly substituted (C-C)-alkyl, possibly substituted and possibly interrupted by up to 3 heteroatoms selected from O, S or N, for their use as antibacterial drugs for the treatment and/or the prevention of infection(s) caused by biofilm-forming bacteria.

Compounds for their use as drugs for the treatment and/or the prevention of infection(s) caused by biofilm-forming bacteria

The present invention relates to a nanocrystalline photocatalyst active upon visible light irradiation, with a high degree of dispersion, stable in the form of a transparent colloidal solution in an aqueous environment, containing nanocrystals of titanium dioxide (TiO) surface-modified via direct chemisorption of organic compounds. The present invention in turn relates to a method of producing the material as well as its use as a photosterilizer, photobacteriocide, photomycocide, and/or photocatalyst, in particular for the sterilization of glass surfaces, transparent plastics and transparent materials, in particular contact lenses, medical catheters, glass and plastic conduits as well as other surfaces, whose sterilization is desirable and/or required.
