    • The invention relates to a compound of formula (1A) or (1B), or a pharmaceutically acceptable salt thereof, Wherein R 1 is a group selected from alkyl, monocyclic heterocycloalkyl, bicyclic heterocycloalkyl and cycloalkyl, each of which is optionally substituted by one or more groups selected from alkyl, halo and cycloalkyl; for formula (1A): one, two or three of X 1 , X 2 , X 3 and X 4 are N, and the remainder are each independently CR 2 ; or for formula (1B): X 4 is C or N; and one or two of X 1 , X 2 and X 3 are independently selected from N and NR 8 , and the remainder are each independently CR 2 ; such that X 1 , X 2 ,X 3 ,X 4 and N form a heteroaryl group; each R 2 is independently selected from H, alkyl, CN, halo, heteroaryl, heterocycloalkyl, cycloalkyl, OR 4 , CONR 5 R 6 and SO 2 R 7 , wherein said alkyl, heteroaryl, heterocycloalkyl and cycloalkyl groups are each optionally further substituted by one or more groups selected from alkyl, halo and OR 9 ; each R 8 is independently selected from H and alkyl, wherein said alkyl group is optionally further substituted by one or more groups selected from CN, halo, heteroaryl, heterocycloalkyl, cycloalkyl, OR 4 , CONR 5 R 6 and SO 2 R 7 ; R 4 , R 5 , R 6 , R 7 and R 9 are each independently selected from H and alkyl; or R 5 and R 6 together with the nitrogen to which they are attached are linked to form a cyclic group which optionally further comprises one or more heteroatoms selected from O, N and S; with the proviso that when the compound is of formula (IB), the compound is other than 3-(5-isopropyl-4H-1,2,4-triazol-3-yl)-N- (tetrahydro-2H-pyran-4-yl)-1H-pyrazolo[4,3-c]pyridin-4-amine or 3-(5-cyclopropyl-4H-,2,4-triazol-3-yl)-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazolo[4,3-c]pyridin-4-amine. Further aspects relate to pharmaceutical compositions, therapeutic uses and process for preparing compounds of formula (1A) and (1B).
    • 本发明涉及式(1A)或(1B)化合物或其药学上可接受的盐,其中R1是选自烷基,单环杂环烷基,双环杂环烷基和环烷基的基团,其各自任选被一个或多个 选自烷基,卤代和环烷基的基团; 对于式(1A):X1,X2,X3和X4中的一个,两个或三个是N,其余各自独立地是CR 2; 或式(1B):X4为C或N; X1,X2和X3中的一个或两个独立地选自N和NR8,其余各自独立地为CR2; 使得X1,X2,X3,X4和N形成杂芳基; 每个R 2独立地选自H,烷基,CN,卤素,杂芳基,杂环烷基,环烷基,OR 4,CONR 5 R 6和SO 2 R 7,其中所述烷基,杂芳基,杂环烷基和环烷基各自任选进一步被一个或多个选自烷基, 卤素和OR9; 每个R 8独立地选自H和烷基,其中所述烷基任选被一个或多个选自CN,卤素,杂芳基,杂环烷基,环烷基,OR4,CONR5R6和SO2R7的基团进一步取代; R4,R5,R6,R7和R9各自独立地选自H和烷基; 或者R 5和R 6与它们所连接的氮一起连接形成环状基团,任选地还包含一个或多个选自O,N和S的杂原子; 条件是当化合物为式(IB)时,该化合物不同于3-(5-异丙基-4H-1,2,4-三唑-3-基)-N-(四氢-2H-吡喃-2-基) 吡啶-4-基)-1H-吡唑并[4,3-c]吡啶-4-胺或3-(5-环丙基-4H-,2,4-三唑-3-基)-N-(四氢-2H-吡喃 -4-基)-1H-吡唑并[4,3-c]吡啶-4-胺。 其它方面涉及药物组合物,治疗用途和制备式(1A)和(1B)化合物的方法。
