The invention relates to a novel use of 8 substituted xanthine derivatives for the manufacture of a medicament for the treatment of auto-immuno disorders.
The invention relates in particular to the use of a xanthine derivative of general formula (I):
wherein:
R1, R2 and R3 are independently hydrogen, saturated or unsaturated aliphatic chains which may be straight or branched having 1 to 6 carbon atoms;
X and Y are independently oxygen or sulfur;
Z1 is selected from the group comprising a thienyl; furanyl; cyclopentyl, phenyl or a substituted by Z2 or unsubstituted phenyl; wherein Z2 is selected from the group comprising phenyl; sulfonic acid; unsubstituted or N-substituted sulfonamide with substituents such as alkyl, aminoalkyl where the amino group may be substituted itself with lower alkyl groups bearing 1 to 4 carbon atoms; nitro; halogen substituted or unsubstituted amino group; aliphatic chain with 1 to 3 carbon atoms; halogenated aliphatic chain with 1 to 3 carbon atoms; aliphatic chain containing ether functions, acids, esters, amides, substituted or unsubstituted amines having 1 to 3 carbon atoms, nitro, sulfonamides or a combination of these functional groups with a maximum length of the chain of 12 atoms,
or a pharmaceutically acceptable salt thereof for the manufacture of a medicament for the treatment of auto-immuno disorders.
本发明涉及一种 8 取代黄嘌呤衍生物用于制造治疗自身免疫疾病药物的新用途。
本发明尤其涉及通式(I)的黄嘌呤衍生物的用途:
其中
R1、R2 和 R3 独立地是氢、饱和或不饱和脂肪族链,可以是直链或支链,具有 1 至 6 个碳原子;
X 和 Y 独立地为氧或硫;
Z1 选自包括噻吩基、呋喃基、环戊基、苯基或被 Z2 取代或未取代的苯基;其中 Z2 选自包括苯基、磺酸、未取代或 N-取代的磺酰胺,其取代基包括烷基、氨基烷基(其中氨基本身可被含 1 至 4 个碳原子的低级烷基取代)、硝基、卤素取代或未取代的氨基烷基、呋喃基、环戊基、苯基或被 Z2 取代或未取代的苯基;卤素取代或未取代的氨基;具有 1 至 3 个碳原子的脂肪族链;具有 1 至 3 个碳原子的卤代脂肪族链;含有醚官能团的脂肪族链、酸、酯、酰胺、具有 1 至 3 个碳原子的取代或未取代的胺、硝基、磺酰胺或这些官能团的组合,链的最大长度为 12 个原子、
或其药学上可接受的盐,用于制造治疗自身免疫性疾病的药物。
