| abstract |
The invention is related to compounds of general formula (I) wherein R is Me, Et, n-Pr, iso-Pr, n-Bu, iso-Bu, sec.-Bu or allyl; R' is hydrogen, Me, MeO, fluoro, chloro, bromo, CF3, or OCH x F y; R" is hydrogen or fluoro, with the proviso that R" is fluoro when R' is fluoro; and further when R' and R" are both hydrogen, R is not Me; R4 is selected from hydrogen and pharmaceutically acceptable inorganic and organic cations; R5 is selected from MeS, EtS, n-PrS, iso-PrS, MeSO, EtSO, MeSO2 and EtSO2: wherein x=0-2, y=1-3 with the proviso that x+y=3; and Me is methyl, Et is ethyl, Pr is propyl and Bu is butyl; and any tautomer, optical isomer and racemate thereof. The invention also relates to pharmaceutical compositions containing a compound of general formula (I) together with a pharmaceutically acceptable carrier. Included are also processes for the preparation of the compounds of formula (I), as well as methods for the treatment of mammals suffering from diseases resulting from autoimmunity and pathological inflammation by administering of a compound having formula (I) to said mammal. |
