  • Publication number: 20250018046
    Abstract: This disclosure relates to compounds of Formula (A): Formula (A), or a pharmaceutically acceptable salt thereof, wherein DSM is a degradation signaling moiety that is covalently attached to the linker L, L is a linker that covalently attaches IRAK to DSM; and IRAK is an IRAK4 binding moiety represented by Formula (I) that is covalently attached to linker L; Formula (I) in which all of the variables are as defined in the application. Compounds or pharmaceutically acceptable salts thereof as described herein are capable of activating the selective ubiqitination of IRAK4 proteins via the ubiquitin-proteasome pathways (UPP) and cause degradation of IRAK4 proteins. The present disclosure also provides methods of treating disorders responsive to modulation of IRAK4 activity and/or degradation of IRAK4 with at least one compound described herein.
