| 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 —SO 2 NR 1 R 2 , whereby R 1 and R 2 , 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. |
