The invention relates to a compound of formula (1A) or (1B), or a pharmaceutically acceptable salt thereof, Wherein R1 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 X1, X2, X3 and X4 are N, and the remainder are each independently CR2; or for formula (1B): X4 is C or N; and one or two of X1, X2and X3 are independently selected from N and NR8, and the remainder are each independently CR2; such that X1, X2,X3,X4and N form a heteroaryl group; each R2 is independently selected from H, alkyl, CN, halo, heteroaryl, heterocycloalkyl, cycloalkyl, OR4, CONR5R6 and SO2R7, wherein said alkyl, heteroaryl, heterocycloalkyl and cycloalkyl groups are each optionally further substituted by one or more groups selected from alkyl, halo and OR9; each R8 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, OR4, CONR5R6 and SO2R7; R4, R5, R6, R7and R9 are each independently selected from H and alkyl; or R5 and R6 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).
该发明涉及公式(1A)或(1B)的化合物,或其药学上可接受的盐,其中R1是从烷基、单环杂环烷基、双环杂环烷基和环烷基中选择的基团,每个基团可选择性地被一个或多个来自烷基、卤素和环烷基的基团取代;对于公式(1A):X1、X2、X3和X4中的一个、两个或三个为N,其余各自独立地为CR2;或对于公式(1B):X4为C或N;X1、X2和X3中的一个或两个独立地从N和NR8中选择,其余各自独立地为CR2;使得X1、X2、X3、X4和N形成一个杂芳基团;每个R2独立地从H、烷基、CN、卤素、杂芳基、杂环烷基、环烷基、OR4、CONR5R6和SO2R7中选择,其中所述的烷基、杂芳基、杂环烷基和环烷基基团可进一步被一个或多个来自烷基、卤素和OR9的基团取代;每个R8独立地从H和烷基中选择,其中所述的烷基基团可进一步被一个或多个来自CN、卤素、杂芳基、杂环烷基、环烷基、OR4、CONR5R6和SO2R7的基团取代;R4、R5、R6、R7和R9各自独立地从H和烷基中选择;或R5和R6与它们连接的氮一起形成一个环状基团,该基团可选择性地进一步包含一个或多个来自O、N和S的杂原子;但是当化合物为公式(IB)时,化合物不是3-(5-异丙基-4H-1,2,4-三唑-3-基)-N-(四氢-2H-吡喃-4-基)-1H-吡唑并[4,3-c]吡啶-4-胺或3-(5-环丙基-4H-1,2,4-三唑-3-基)-N-(四氢-2H-吡喃-4-基)-1H-吡唑并[4,3-c]吡啶-4-胺。进一步涉及制备公式(1A)和(1B)化合物的药物组合物、治疗用途和工艺方面。
