The invention relates to thienopyrimidinediones of formula (1) wherein R1 and R2 each independently represent a C1-6alkyl, C3-6alkyl, C3-6alkenyl, C3-5cycloalkylC1-3alkyl or C3-6cycloalkyl; each of which may be optionally substituted by 1 to 3 halogen atoms R3 is a group CO-G or SO2-G where G is a 5- or 6-membered ring containing a nitrogen atom and a second heteroatom selected from oxygen and sulphur adjacent to the nitrogen; the ring being substituted by at least one group as defined in the specification, Q is CR4R5 where R4 is hydrogen, fluorine or C1-6 alkyl and R5 is hydrogen, fluorine or hydroxy; and Ar is a 5-10-membered aromatic ring system wherein up to 4 ring atoms may be heteroatoms independently selected from nitrogen, oxygen and sulphur, the ring system being optionally substituted by one or more groups defined in the specification; as well as pharmaccutically acceptable salts and solvates thereof. Processes for their preparation of the compounds, pharmaceutical compositions containing them and their use in therapy, in particular in immunosuppressive therapy are also described
本发明涉及公式(1)的噻唑嘧啶二酮,其中R1和R2各自独立地表示C1-6烷基,C3-6烷基,C3-6烯基,C3-5环烷基C1-3烷基或C3-6环烷基; 每个基团可以选择性地被1到3个卤素原子取代,R3是一个CO-G或SO2-G基团,其中G是一个5或6成员环,其中包含一个氮原子和一个在氮原子旁边选择的氧或硫的第二个杂原子; 该环可以被至少一个在规范中定义的基团取代,Q是CR4R5,其中R4是氢,氟或C1-6烷基,R5是氢,氟或羟基; Ar是一个5-10成员芳香环系统,其中最多4个环原子可以是氮,氧和硫的杂原子,该环系统可以被一个或多个在规范中定义的基团取代;以及其药学上可接受的盐和溶剂物。还描述了制备这些化合物的过程,包含它们的制药组合物以及它们在治疗中的使用,特别是在免疫抑制治疗中的使用。
