Abstract

The present disclosure relates to compounds that act as inhibitors of NLRP3 inflammasomes; pharmaceutical compositions comprising the compounds; and methods of treating disorders associated with inflammation and inflammaging, including hearing loss and other diseases associated with aging; wherein the inhibitors of NLRP3 inflammasomes are compounds of Formula VII: or a pharmaceutically acceptable salt thereof.

Claims (68)

1. A method of inhibiting NLRP3 inflammasome in a subject in need thereof comprising administering to the subject a therapeutically effective amount of a compound of Formula VII:

or a pharmaceutically acceptable salt thereof, wherein

X, Y, and Z, together with the ring to which they are attached, form

2. The method of claim 1 , wherein the compound of Formula VII is selected from the group consisting of

or a pharmaceutically acceptable salt thereof.
