Fumaric acid derivatives of the formula <IMAGE> (I) wherein R1 is a hydrogen atom, a C1-C8 alkyl group or a metallic cation, and R2 is a saturated or unsaturated aliphatic C6-C24 alkyl group, psoralen-9-yl, retinyl, alpha -tocopheryl (vitamin E), calciferyl, corticosteroid-21-yl or monosaccharid- omega -yl; a group of fumaric acid derivatives based on glycerol, alkane diol or polyol molecules; and fumaric acid derivatives of the formula <IMAGE> (IX) wherein n is an integer from to 30 to 260, R3 is a hydrogen atom or a C1-C3 alkyl group, R4 is one of the R3 groups and n is the number of molecule repetitions, processes for their production and compositions containing same are described. These compounds are useful as drugs for the treatment of cryptogenically-caused diseases and have antisporiatic as well as antimicrobial action. |
