  • Patent number: 7507725
    Abstract: The invention relates to compounds which, acting as a prodrug and/or support, enable an active agent to be taken up by the erythrocytes and/or an active agent to bind to the erythrocytes. The uptake of these compounds by and/or the binding thereof to the erythrocytes is made possible by a group of formula —SO2NR1R2, wherein R1 and R2, independently of each other, mean a hydrogen atom, an acyl group, an alkyl group, a cycloalkyl group, an aryl group, a cyano group or a hydroxy group. The inventive prodrugs enable active agents such as endogenic substances, natural substances and synthetic substances with therapeutically useful properties which have a high “first path” effect, to be administered orally effectively or significantly improve the oral activity thereof.

  • Publication number: 20090023896
    Abstract: This invention relates to compounds that as prodrugs and/or vehicles make it possible for an active ingredient to be taken up into erythrocytes and/or an active ingredient to bind to erythrocytes, whereby the uptake of the compounds into erythrocytes and/or the binding of the compounds to erythrocytes is made possible by a group —SO2NR1R2, whereby R1 and R2, independently of one another, mean a hydrogen atom, an acyl group, an alkyl group, a cycloalkyl group, an aryl group, a cyano group or a hydroxy group. By the prodrugs according to the invention, active ingredients, such as endogenous substances, natural substances and synthetic substances with therapeutically valuable properties with a high “first pass” effect are made available orally to a reasonable extent or are decisively improved relative to oral activity.
