摘要

The present invention relates to compounds of formula I, or pharmaceutically acceptable salts or esters thereof, (Formula I) wherein R1 is selected from: aryl; heteroaryl; -NHR3; fused aryl-C4_7-heterocycloalkyl; -CONR4R5; - NHCOR6; -C3-7-cycloalkyl,-NR3R6; -OR3; OH; NR4R5; and alkyl optionally substituted with a substituent selected from R11 and a group A; wherein said aryl, heteroaryl, fused aryl-C4-7-heterocycloalkyl and C4-7- heterocycloalkyi are each optionally substituted with one or more substituents selected from C1-6-alkyl, C3-7-cycloalkyl, heteroaryl, C4-7-heterocycloalkyl, aryl and a group A, and said C1-6-alkyl, C3-7-cycloalkyl, heteroaryl, C4-7-heterocycloalkyl, and aryl substituents are in turn each optionally substituted with one or more groups selected from R11 and a group A; R2 is selected from hydrogen, aryl, C1-6-alkyl, C2-6-alkenyl, C3-7-cycloalkyl, heteroaryl, heterocycloalkyi, fused aryl-C4-7-rheterocycloalkyl and halogen, wherein said C1-6-alkyl, C2-6-alkenyl, aryl, heteroaryl, fused aryl-C4-7-heterocycloalkyl and C4-7-heterocycloalkyl are each optionally substituted with one or more substituents selected from R11 and A. Further aspects relate to pharmaceutical compositions and therapeutic uses of said compounds.
