JNJ-1013 is a proteolysis-targeting chimera (PROTAC) containing the IL-1 receptor-associated kinase 1 (IRAK1) and IRAK4 inhibitor JH-I-25 and a methylated derivative of the PROTAC building block VH 032 (Item No. 39982).1 It degrades IRAK1 with a half-maximal degradation concentration (DC50) value of 3.3 nM in HBL-1 diffuse large B cell lymphoma (DLBCL) cells and is selective for IRAK1 over 7,548 proteins but does degrade cyclin G-associated kinase (GAK) and NmrA-like family domain-containing protein 1 (NMRAL1) at 1 µM. JNJ-1013 (0.3-1 µM) decreases phosphorylated levels of IκBα and STAT3 in HBL-1 cells. It reduces the proliferation of HBL-1 and OCI-LY10 DLBCL cells (IC50s = 60 and 170 nM, respectively).
WARNING This product is not for human or veterinary use.
