Novel antiseptic derivatives with broad spectrum antimicrobial activity for the impregnation of surfaces

Abstract From the Canadian patent

The present invention provides novel broad spectrum antiseptic compounds comprising a basic reagent (such as a guanidium compound a biguanide, a , bipyridine, aphenoxide or an alkyl oxide) bound to a dye that further have , properties that allow them to be coated/impregnated into polymer surfaces. Methods for coating these antiseptic compounds onto medical devices especially in-dwelling medical devices to prevent the growth of pathogens in such devices and hence, to prevent infection to patients via such devices are provided. The invention also provides antiseptics that are useful as general surface disinfectants and sterilizers, fluid disinfectants and biocide preservatives.
