Kind Code:
A1
Abstract:
Provided are: a 6-aminopyrazolopyrimidine compound having an inhibitory activity on NLRP3 inflammasomes or a pharmaceutically acceptable salt thereof; a pharmaceutical composition containing the same; and a pharmaceutical use thereof. A compound represented by formula [IA] or a pharmaceutically acceptable salt thereof. [IA] (In the formula, the partial structure [2] is a structure represented by formula [3] (in the formula, R4 is hydrogen or a C1-4 alkyl (where the alkyl may be substituted with hydroxy or cyano)), and a cyclic group CyA is a group represented by formula [5] (in the formula, R6 and R7 are each independently hydrogen, hydroxy, cyano, C1-6 alkyl, or the like, R8 and R9 are each independently hydrogen, C1-4 alkyl, or C1-4 haloalkyl, and R10 is hydrogen, cyano, C1-6 alkyl, or the like), R1 is hydrogen or C1-4 alkyl, R2A and R3A are each independently hydrogen, C1-6 alkyl, or the like, or R2A and R3A together with a nitrogen atom to which they are bonded may form a 4-membered to 7-membered heterocycloalkyl, or the like, to which a -NR2AR3A group may be substituted.)
