| abstract |
Derivatives of verbascoside and the pharmaceutical compositions containing them are the subject matter of the present invention. In particular, the present invention relates to compounds of Formula (I), wherein R, R 1 , R 2 and R 3 are the same or different and are independently selected from hydrogen and a residue of a carboxylic acid, wherein the ester groups R-O-, R 1 -O, R 2 -O- and R 3 -O-, respectively, are hydrolysable to a pH ranging between 4.5 and 7, provided that R, R 1 , R 2 and R 3 are not simultaneously hydrogen. |
