The invention provides pharmaceutically active agents of the structural formula <IMAGE> (I) wherein n is 1 or 2; X is Z if n is 1 and X is CH2Y, CH2OH or OH if n is 2; Y is OH if n is 1 and, if n is 2, one of the radicals Y is Z and all other radicals Y are OH; <IMAGE> R11 is a C3-C10 linear or branched alkyl; a C3-C5 linear or branched alkenyl or alkynyl; a C2-C4 linear or branched alkyl substituted by C1-C4 alkoxy, methoxymethoxy, methoxyethoxy, or hydroxyethoxy radicals; C3-8 cycloalkyl; C1-3 alkyl substituted with C3-8 cycloalkyl groups; benzyl; benzyl having 1 to 3 substituents selected from the group consisting of C1-4 alkyl, C1-4 alkoxy and cyclopropyl; phenethyl; tetrahydrofurfuryl, furfuryl; morpholinoethyl, morpholinopropyl; piperidinoethyl; and R12 is a C1-C10 linear or branched alkyl; C3-C5 linear or branched alkenyl or alkynyl; C1-6 hydroxyalkyl; C2-4 linear or branched alkyl substituted by C1-4 alkoxy or C1-4 hydroxyalkoxy; C3-8 cycloalkyl; C1-3 alkyl substituted by a C3-8 cycloalkyl radical; benzyl, chlorobenzyl; benzyl having 1 to 3 substituents selected from the group consisting of C1-4 alkyl and C1-4 alkoxy; tetrahydrofurfuryl; furfuryl; morpholino; morpholinoethyl; morpholinopropyl; thiophen-2-yl-methyl; pyridylethyl; and piperidinoethyl.
