1. A pharmaceutical preparation containing as active ingredient a compound of the formula
wherein R, and R2 are the same or different, and each is selected from the group consisting of hydrogen, alkyl groups containing 1-6 carbon atoms; cycloalkyl groups containing 3-6 carbon atoms; cycloalkyl-alkyl groups containing 4-6 carbon atoms: 1-adamantyl; 2-adamantyl, benzyl; and phenyl groups of the formula
wherein R. and R5 are the same or different, and each is selected from the group consisting of hydrogen, halogen, alkyl having 1, 2, or 3 carbon atoms, alkoxy having 1, 2, or 3 carbon atoms, alkoxycarbonyl having 2-7 carbon atoms and alkylcarbonyl groups having 2-7 carbon atoms; or R. and R5 together form a straight saturated alkylene chain having 3 or 4 carbon atoms and being bound to adjacent positions, i.e. 2,3- or 3,4- in the phenyl ring;
and R3 is selected from the group consisting of hydrogen, alkyl groups containing 1-8 carbon atoms; cycloalkyl groups containing 3-8 carbon atoms; cycloalkyl-alkyl groups containing 4-8 carbon atoms; 1-adamantyl; 2- adamantyl; benzyl; and phenyl groups of the formula
wherein R4 and Rs have the meaning given above; provided that at least one of the groups R,, R2 and R3 is alkyl, cycloalkyl, or cycloalkyl-alkyl as defined above, or 1-adamantyl, 2-adamantyl, or benzyl; and provided that when R3 is H, then one of R, and R2 is alkyl, cycloalkyl, or cycloalkyl-alkyl as defined above, or 1-adamantyl, 2-adamantyl, or benzyl and the other of R, and R2 is H; or a physiologically acceptable salt or an optical isomer thereof; novel compounds within formula I, methods for their preparation and their medicinal use.
